Describe the solution of h(x) shown in the graph.
a parabola opening up passing through negative 1 comma zero, zero comma negative 2, and 2 comma zero
A. All solutions that lie on h(x)
B. All real solutions
C. All whole number solutions
D. All positive solutions
Answer:
Step-by-step explanation:
This is a reading question. You have to know what all the terms mean.
B: is the first one you have to think about. All real solutions. Is that the answer, or do you have to think about it more. The key word is solutions. So that takes in A. So B is the answer.
A is the second best answer. Any solution has to be on the blue line. The blue line is the visual record of what works in B. Well, why not pick A? It is because B is more general, and it includes A.
C More than whole numbers solve this question. The line is continuous.
D There are negative solutions as well. Not the answer.
Answer:
the answer is A. All solutions that lie on h(x)

Given f(x)= 2^x and g(x)=x^2 answer the questions that follow
a. Your friend claims the graph of f(x)=2x increases at a faster rate than the graph of g(x)=x2 when x ≥ 0. Is your friend correct? Explain your reasoning.
b. How are the 2 functions different?
PLEASE HELP
Answer:
a. Yes it's correct, reasons;
I) let x=1, f(1)=2^1=2, g(x)=1^2=1 this proves that when a higher number is used the value of f(x) will be higher than g(x).
ii) As x approaches zero f(x) approaches 1, but g(x) approaches 0. Which will make the rate at which the graph of f(x) increase be faster than g(x)
b. f(x) has an infinite degree but g(x) has a finite degree of 2.

A standard number die is tossed once, and then again. Find P(first
roll = 1 and second roll = 1),
help pls
Answer:
1/36
Step-by-step explanation:
A standard die has 6 faces
The numbers 1 through 6 on singly on each face
so the probability of tossing a 1 would be;
1/6
The probability of tossing another 1 would still be same 1/6
So the probability of tossing a 1 and another 1 would be the product of the two tosses as follows;
1/6 * 1/6 = 1/36
a person earns 17/5 dollars in 1/2 hours. What is the unit rate in dollars pure hour
Answer:
35 2/3 dollars per hour
Step-by-step explanation:
The unit rate in dollars per hour is 6.8 dollars per hour.
To find the unit rate in dollars per hour, we need to divide the amount earned by the time taken.
The person earns 17/5 dollars in 1/2 hours. To calculate the unit rate in dollars per hour, we divide the amount earned (17/5 dollars) by the time taken (1/2 hours):
Unit rate = (Amount earned) / (Time taken) = (17/5 dollars) / (1/2 hours)
To divide fractions, we multiply the numerator of the first fraction by the reciprocal of the second fraction:
Unit rate = (17/5 dollars) x (2/1 hours)
Simplifying the expression:
Unit rate = (17 x 2) / (5 x 1) = 34/5 = 6.8
Therefore, the unit rate in dollars per hour is 6.8 dollars per hour.

Answer:
copper ?? the "slope" is 8.75
Step-by-step explanation:
A walking path across a park is represented by the equation y=-3x - 6. A new path will be built perpendicular to this path. The paths will intersect at the point (-3,3). Identify the equation that represents the new path 10- 20 10
The equation of the new path would be y=1/3x+4.
Explanation
If two lines are perpendicular, their slopes are negative reciprocals of each other. The original equation is written in slope-intercept form, y=mx+b, where m is the slope. In this equation, m=-3=-3/1.
In the new equation, the slope would be the opposite sign and flipped; this means it would be 1/3.
We can use the point given, the slope and slope-intercept form to write the equation of the new line:
y=mx+b
3=1/3(-3)+b
3=1/3(-3/1)+b
3=(-3/3)+b
3=-1+b
Add 1 to both sides:
3+1=-1+b+1
4=b
This makes the equation y=1/3x+4.
Answer:
B
Step-by-step explanation:
> if the lines are perpendicular then their slopes are negative reciprocal so
y=mx+b , is the general form where is m = slope
y= -3x -4, old path has slope m= -3
y= (1/3)x +b , is the new path with slope m=(1/3)
>if the paths intersect at (-3,3) then this point is on the new path as well
y= (1/3)x +b, now substitute x= -3, and y=3 to find b
3 = (1/3)(-3)+b , divide -3/3
3= -1 +b, add 1 to both sides
4 = b
>the equation of the new path is
y= (1/3)x +4

Step-by-step explanation:
Solve the equation they've given you:
[tex]\frac{3}{4} S=60\\\frac{3S}{4} =60\\3S=60*4\\3S=240\\S=80[/tex]
Answer:
B. 80
Step-by-step explanation:
(3/4)S = 60
You want to isolate S. S is being multiplied by 3/4.
You need to multiply 3/4 by its reciprocal to get rid of the 3/4 on the left side.
The reciprocal of 3/4 is 4/3.
The rule with equations is that you are allowed to multiplied both sides of an equation by the same number. Multiply both sides of the equation by 4/3.
4/3 * (3/4) * S = 4/3 * 60
12/12 * S = 4/3 * 60/1
1 * S = 240/3
S = 80

At the movie theatre, child admission is $5.70 and adult admission is $9.50, 146 tickets were sold for a total sales of $1075.40. How many adult tickets were sold that day?
Answer:
x = number of children tickets sold = 82 tickets
y = number of adult tickets sold = 64 tickets
Step-by-step explanation:
Let
x = number of children tickets sold
y = number of adult tickets sold
x + y = 146 (1)
5.70x + 9.50y = 1075.40 (2)
From (1)
x = 146 - y
Substitute x = 146 - y into (2)
5.70x + 9.50y = 1075.40 (2)
5.70(146 - y) + 9.50y = 1075.40
832.2 - 5.70y + 9.50y = 1075.40
- 5.70y + 9.50y = 1075.40 - 832.2
3.8y = 243.2
y = 243.2/3.8
y = 64
Substitute y = 64 into (1)
x + y = 146
x + 64 = 146
x = 146 - 64
x = 82
x = number of children tickets sold = 82 tickets
y = number of adult tickets sold = 64 tickets

A. 145
B. 35
C. 55
D. 75
Explanation:
Angles 4 and 8 are corresponding angles since they are both in the southwest corner of their respective 4 corner configuration.
Corresponding angles are congruent when we have parallel lines like this.
Set the expressions equal to each other and solve for x
angle 4 = angle 8
x+20 = 2x+5
x-2x = 5-20
-x = -15
x = 15
Use this x value to find the two angles to help confirm we have the correct x value, and to finish up to answer the question.
angle 4 = x+20 = 15+20 = 35angle 8 = 2x+5 = 2(15)+5 = 30+5 = 35So that's why the answer is B) 35 degrees

Enter a decimal rounded to the nearest hundredth.
Answer:
Answer is 0.14.
Step-by-step explanation:
The probability that a student earns a grade of D or F is 0.14.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To find the probability that a student earns a grade of D or F, we need to add the frequencies of these two grades and divide by the total number of students:
P(D or F) = (3 + 2) / 35
P(D or F) = 5 / 35
P(D or F) = 0.14 (rounded to the nearest hundredth)
Therefore,
The probability that a student earns a grade of D or F is 0.14.

Diego deposited \$ 10,000$10,000 for 44 years at a rate of 6\%6% simple interest. Find the amount of interest Diego earned after four years.
Answer:
$2,400
Step-by-step explanation:
Note: The correct years is 4 not 44
The Principal = $10,000
Time period = 4 years
Rate = 6 % p.a.
Simple Interest = Principal * Rate * Time
Simple Interest = $10,000 * 6% * 44
Simple Interest = $2,400
So, the amount of interest Diego earned after four years is $2,400
A student drops their notes and their papers scatter. The fact that the papers scatter and do not remain neatly stacked is an illustration of :
Answer:
-- increase in entropy
-- second law of thermodynamics
Step-by-step explanation:
The 1st law of thermodynamic states that there is conservation of energy, i.e. we cannot create energy and we cannot destroy energy also in an isolated system.
The given example is not a representative of the 1st law.
The [tex]\text{2nd law of thermodynamics}[/tex] states that there is a natural tendency of an isolated system to [tex]\text{degenerate}[/tex] into a more [tex]\text{disordered state.}[/tex] Before dropping the notes and papers were in an isolated ordered system.
After dropping the papers scattered and did not remain in a stack position. It moves into a more disordered state.
Begore dropping down the notes and papers, they were in a stable position, i.e. no kinetic energy is there. No randomness when the notes and the papers were dropped. There is an increase in kinetic energy. There is randomness among the molecules by bombardment. So there is an increase in entropy.
Thus, above illustrations represents :
