When a vehicle is in motion, it has _____. A. no weight B. no inertia C. potential energy D. kinetic energy
Answer:
D kinetic energy
Step-by-step explanation:
When a vehicle is in motion, it has kinetic energy. Option C is correct.
The statement is given, When a vehicle is in motion, it has _____.
Blank statement to be filled from the options A. no weight B. no inertia C. potential energy D. kinetic energy.
When an object is subjected to perform a motion by the action of force induced by external means the object's potential energy transforms into kinetic energy. Or kinetic energy is half the product of mass and square of the velocity.
When a vehicle is in motion. it has both kinetic energy and inertia because a vehicle has velocity and weight respectively. Since kinetic energy is directly proportional to the square of velocity, inertia is directly proportional to weight. In option, we have only kinetic energy options.
Thus, When a vehicle is in motion, it has kinetic energy. Option C is correct.

A graphing calculator is recommended. A function is given. g(x) = x4 − 5x3 − 14x2 (a) Find all the local maximum and minimum values of the function and the value of x at which each occurs. State each answer rounded to two decimal places.
Answer:
The local maximum and minimum values are:
Local maximum
[tex]g(0) = 0[/tex]
Local minima
[tex]g(5.118) = -350.90[/tex]
[tex]g(-1.368) = -9.90[/tex]
Step-by-step explanation:
Let be [tex]g(x) = x^{4}-5\cdot x^{3}-14\cdot x^{2}[/tex]. The determination of maxima and minima is done by using the First and Second Derivatives of the Function (First and Second Derivative Tests). First, the function can be rewritten algebraically as follows:
[tex]g(x) = x^{2}\cdot (x^{2}-5\cdot x -14)[/tex]
Then, first and second derivatives of the function are, respectively:
First derivative
[tex]g'(x) = 2\cdot x \cdot (x^{2}-5\cdot x -14) + x^{2}\cdot (2\cdot x -5)[/tex]
[tex]g'(x) = 2\cdot x^{3}-10\cdot x^{2}-28\cdot x +2\cdot x^{3}-5\cdot x^{2}[/tex]
[tex]g'(x) = 4\cdot x^{3}-15\cdot x^{2}-28\cdot x[/tex]
[tex]g'(x) = x\cdot (4\cdot x^{2}-15\cdot x -28)[/tex]
Second derivative
[tex]g''(x) = 12\cdot x^{2}-30\cdot x -28[/tex]
Now, let equalize the first derivative to solve and solve the resulting equation:
[tex]x\cdot (4\cdot x^{2}-15\cdot x -28) = 0[/tex]
The second-order polynomial is now transform into a product of binomials with the help of factorization methods or by General Quadratic Formula. That is:
[tex]x\cdot (x-5.118)\cdot (x+1.368) = 0[/tex]
The critical points are 0, 5.118 and -1.368.
Each critical point is evaluated at the second derivative expression:
x = 0
[tex]g''(0) = 12\cdot (0)^{2}-30\cdot (0) -28[/tex]
[tex]g''(0) = -28[/tex]
This value leads to a local maximum.
x = 5.118
[tex]g''(5.118) = 12\cdot (5.118)^{2}-30\cdot (5.118) -28[/tex]
[tex]g''(5.118) = 132.787[/tex]
This value leads to a local minimum.
x = -1.368
[tex]g''(-1.368) = 12\cdot (-1.368)^{2}-30\cdot (-1.368) -28[/tex]
[tex]g''(-1.368) = 35.497[/tex]
This value leads to a local minimum.
Therefore, the local maximum and minimum values are:
Local maximum
[tex]g(0) = (0)^{4}-5\cdot (0)^{3}-14\cdot (0)^{2}[/tex]
[tex]g(0) = 0[/tex]
Local minima
[tex]g(5.118) = (5.118)^{4}-5\cdot (5.118)^{3}-14\cdot (5.118)^{2}[/tex]
[tex]g(5.118) = -350.90[/tex]
[tex]g(-1.368) = (-1.368)^{4}-5\cdot (-1.368)^{3}-14\cdot (-1.368)^{2}[/tex]
[tex]g(-1.368) = -9.90[/tex]

The breaking strength of hockey stick shafts made of two different graphite-Kevlar composites yield the following results (in newtons):
Composite A: 487.3 444.5 467.7 456.3 449.7 459.2 478.9 461.5 477.2
Composite B: 488.5 501.2 475.3 467.2 462.5 499.7 470.0 469.5 481.5
485.2 509.3 479.3 478.3 491.5
Assuming normality, can you conclude that the mean breaking strength is smaller for hockey sticks made from composite B by at least 2 newtons? Carry out the appropriate test by hand.
Answer:
We reject H₀
we don´t have evidence to claim the strength of composite B is smaller than the strength of composite B by at least 2 [N]
Step-by-step explanation:
From data, we calculate μ₁, s₁ and, μ₂, s₂ mean and standard deviation of samples A and B respectively
μ₁ = 464,7 s₁ = 13,42 Composite A
μ₂ = 479,49 s₂ = 13,38 Composite B
n₁ ; n₂ < 30 then we should use t -student table
Test Hypothesis:
Null Hypothesis H₀ μ₂ - μ₁ >= 2
Alternative Hypothesis Hₐ μ₂ - μ₁ < 2
Assuming CI 95 % α = 5 % α = 0,05 and degree of freedom is
df = n₁ + n₂ - 2 df = 9 + 9 - 2 df = 16
Then for a one tail test t(c) = 1,746 and to compte t(s)
t(s) = ( μ₂ - μ₁ - 2 ) / sp * √ 1/n₁ + 1/n₂
sp² = ( n₁ - 1 )*s₁² + ( n₂ - 1 )*s₂² / n₁ + n₂ - 2
sp² = 8 * (13,42)² + 8 * (13,38)² / 16
sp² = (8 * 180,1 + 8 * 179) / 16
sp² = 179,55
sp = 13,40
then
t(s) = ( 479,49 - 464,7 - 2 ) / 13,40*√1/9 +1/9
t(s) = 12,79 / 13,40*0,4714
t(s) = 12,79/6,32
t(s) = 2,02
t(s) > t(c)
2,02 > 1,746
t(s) is in the rejection region, therefore we reject H₀ we don´t have evidence to claim the strength of composite B s smaller than the strength of composite B by at least 2 [N]

Classify the data as qualitative or quantitative. If qualitative then classify it as ordinal or categorical, and if quantitative then classify it as discrete or continuous. Variable Height (in inches) Grade (ABCDF) Weight (exact) Color Data Type a Quantitative Continuous b Quantitative Discrete c Qualitative Categorical d Qualitative Ordinal
Answer:
Explained below.
Step-by-step explanation:
Qualitative variables are categorized or labelled to belong to a certain category or group.
There are two types of qualitative variables, Categorical and ordinal.
Categorical variable are those variables that are labelled in non-numeric or numeric form, where the numbers have no value. The order also does not matters. For example, the number on the jerseys of football players. It is not necessary that the player number 1 is actually the best player.
Ordinal variables are those variables where the label or category has to be in order. For example, the rank of students in the statistics class.
Quantitative variables are in numerical form and can be measured.
There are two types of quantitative variables, discrete and continuous.
Discrete variables are those variables that assume finite and specific value. For example, the number of girls in each section of a school.
Continuous variables are those variables that can assume any number of values between a specific interval. For example, the time it takes to reach point B from A.
Variable Category Sub-Category

Answer:
$42
Step-by-step explanation:
Original price: $56
Discount: 25%
A discount of 25% means that the discount is 25% of the price of the item, so you need to subtract 25% of the price of the item from the original price of the item.
Let's find an expression for the amount of the discount.
25% of $56 = 25% * $56 = 0.25 * $56
The amount of discount is 0.25 * $56.
Now we subtract that amount form the original price of $56.
$56 - 0.25 * $56 = $56 - $14 = $42

BRAINLIEST IF RIGHT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Trevon's Custom Kitchen Supplies sells handmade forks and spoons. It costs the store $1.80 to buy the supplies to make a fork and $1.40 to buy the supplies to make a spoon. The store sells forks for $4.60 and spoons for $5.40. Last April Trevon's Custom Kitchen Supplies spent $24.60 on materials for forks and spoons. They sold the finished products for a total of $73.80. How many forks and how many spoons did they make last April? A. 8 forks and 10 spoons B. 8 forks and 8 spoons C. 9 forks and 9 spoons D. 9 forks and 6 spoons
Answer:
D. 9 forks and 6 spoons
Step-by-step explanation:
Let's calculate how many forks and spoons were made. We need to guess a pair of variable values that will add up to $24.60. We'll do this by substituting all the possible pairs in:
Here's the pair for A:
[($1.80 * a) + ($1.40 * b)]
= [($1.80 * 8) + ($1.40 * 10)]
= [$14.40 + $14]
= $28.40
Is $28.40 equal to $24.60? No, this is not correct.
Here's the pair for B:
[($1.80 * a) + ($1.40 * b)]
= [($1.80 * 8) + ($1.40 * 8)]
= [$14.40 + $10.80]
= $25.20
Is $25.20 equal to $24.60? No, this is not correct.
Here's the pair for C:
[($1.80 * a) + ($1.40 * b)]
= [($1.80 * 9) + ($1.40 * 9)]
= [$16.20 + $12.60]
= $28.80
Is $28.80 equal to $24.60? No, this is not correct.
Here's the pair for D:
[($1.80 * a) + ($1.40 * b)]
= [($1.80 * 9) + ($1.40 * 6)]
= [$16.20 + $8.40]
= $24.60
Is $24.60 equal to $24.60? Yes, this is correct.
Therefore, we know the answer is (D) 9 forks and 6 spoons
We can also check by substituting these values to find the amount Trevon's Custom Kitchen Supplies earned last April:
[($4.60 * a) + ($5.40 * b)]
= [($4.60 * 9) + ($5.40 * 6)]
= [$41.40 + $32.40]
= $73.80
This is equal to the amount of money earned last April.
I hope this helps! Tell me if I'm wrong, please!

With nothing% confidence, it can be said that most driving distances to work (in miles) in the population are between the interval's endpoints. D. With nothing% confidence, it can be said that the population mean driving distance to work (in miles) is between the interval's endpoints.
Answer:
With 99 % confidence, it can be said that the population mean driving distance to work (in miles) is between the interval's endpoints [19.91 miles, 31.49 miles] .
Step-by-step explanation:
The complete question is: In a random sample of six people, the mean driving distance to work was 25.7 miles and the standard deviation was 6.7 miles. Assuming the population is normally distributed and using the t-distribution, a 99% confidence interval for the population mean mu is left parenthesis 14.7 comma 36.7 right parenthesis (and the margin of error is 11.0).
Through research, it has been found that the population standard deviation of driving distances to work is 5.5 . Using the standard normal distribution with the appropriate calculations for a standard deviation that is known, find the margin of error and construct a 99 % confidence interval for the population mean mu .
Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.)
A. nothing % of all random samples of six people from the population will have a mean driving distance to work (in miles) that is between the interval's endpoints.
B. With nothing % confidence, it can be said that most driving distances to work (in miles) in the population are between the interval's endpoints.
C. It can be said that nothing % of the population has a driving distance to work (in miles) that is between the interval's endpoints.
D. With nothing % confidence, it can be said that the population mean driving distance to work (in miles) is between the interval's endpoints.
We are given that in a random sample of six people, the mean driving distance to work was 25.7 miles and the standard deviation was 6.7 miles.
Through research, it has been found that the population standard deviation of driving distances to work is 5.5 .
Firstly, the pivotal quantity for finding the confidence interval for the population mean is given by;
P.Q. = [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] ~ N(0,1)
where, [tex]\bar X[/tex] = sample mean driving distance to work = 25.7 miles
[tex]\sigma[/tex] = population standard deviation = 5.5 miles
n = sample of people = 6
[tex]\mu[/tex] = population mean driving distance to work
Here for constructing a 99% confidence interval we have used a One-sample z-test statistics because we know about the population standard deviation.
So, 99% confidence interval for the population mean, [tex]\mu[/tex] is ;
P(-2.58 < N(0,1) < 2.58) = 0.99 {As the critical value of z at 0.5% level
of significance are -2.58 & 2.58}
P(-2.58 < [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] < 2.58) = 0.99
P( [tex]-2.58 \times {\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]{\bar X-\mu}[/tex] < [tex]2.58 \times {\frac{\sigma}{\sqrt{n} } }[/tex] ) = 0.99
P( [tex]\bar X-2.58 \times {\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]\mu[/tex] < [tex]\bar X+2.58 \times {\frac{\sigma}{\sqrt{n} } }[/tex] ) = 0.99
99% confidence interval for [tex]\mu[/tex] = [ [tex]\bar X-2.58 \times {\frac{\sigma}{\sqrt{n} } }[/tex] , [tex]\bar X+2.58 \times {\frac{\sigma}{\sqrt{n} } }[/tex] ]
= [ [tex]25.7-2.58 \times {\frac{5.5}{\sqrt{6} } }[/tex] , [tex]25.7+2.58 \times {\frac{5.5}{\sqrt{6} } }[/tex] ]
= [19.91, 31.49]
Therefore, a 99% confidence for the population mean is [19.91, 31.49] .
The margin of error here is = [tex]2.58 \times {\frac{\sigma}{\sqrt{n} } }[/tex]
= [tex]2.58 \times {\frac{5.5}{\sqrt{6} } }[/tex] = 5.793
With 99 % confidence, it can be said that the population mean driving distance to work (in miles) is between the interval's endpoints [19.91, 31.49] .

graph. Enter exponents using the caret (-); for example, enter x2 as x^2.
The answer : (x-5)^2 .....................................(x-5)square
For example, for f(x)= x square . For x=1 ,then, y=1 .
But consider the g function. the minimum value that g function has is x is 5. When x is 5, y is 0 . So (x-5)square is the equation of this function.
The complete equation of the blue graph is (x-5)^2.
What is a function?
Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
Red graph equation= X^2
Now,
In blue graph it shifted by 5 units to the right
For blue graph
x=5
Putting the value of x in red graph equation
=(x-5)^2
=x^2 + 25 - 10x
Therefore, by the given graph function will be (x-5)^2.

Devon bought running shocs at a price that was 1/4 off the original price of $88. He paid a sales tax of 7% on
the discounted price and gave the clerk four $20 bills.
How much change should he receive?
A. $ 4.62
B. $ 7.84
C. $ 9.38
D. $12.46
E. $18.62
The correct answer is C. $ 9.38
Explanation:
The first step to solve this mathematical problem is to know the price of the shoes. About this, we know the price is 1/4 of $88 plus taxes. You can find how much is 1/4 of $88 by following this process:
1. Write the amounts given
[tex]\frac{1}{4}[/tex] of [tex]88[/tex]
2. Divide the number by the denominator (bottom number) and then multiply by the numerator
[tex]88[/tex] ÷ [tex]4 = 22[/tex]
[tex]22 x 1 = 22[/tex]
This means the discount was $22 and $88- $22 = $66, which is the price with the discount. Now, it is necessary to add the sales tax, which can be done by finding the 7% of $66 and adding this number to $66 (the price of the shoes including the 1/4 discount)
1. Write the values
66 = 100 (66 represents the total or 100%)
x = 7 (7% is the value you want to know and the x represents the value is not known)
2. Cross multiply
x 100 = 462
3. Find x
x = 462 ÷ 100
x = 4. 62 ( value of taxes)
Now, add the taxes to the price $66 + $ 4.62 = $70.62 (price with taxes). Finally, we know Devon paid using four $20 bills. This means he gave the clerk $80 ($20 x 4 = $80). Finally, to know how much is the change subtract the price of the shoes from the money Devon gave the clerk $80 - $70.62 = $9.38
