Answer:
b. 156
Step-by-step explanation:
A "perfect square" is the product of an integer that is being multiplied by itself.
Choice a, 625, is a perfect square because it is the product of 25 multiplied by itself.
25 x 25 = 625Choice b, 156, is not a perfect square because you cannot find any integer that can be multiplied by itself that will result in 156 as a product. Therefore, this is the correct answer.
Choice c, 196, is a perfect square because it is the product of 14 multiplied by itself.

please give thanks by hitting heart button! :)
Answer:
15%
Step-by-step explanation:
1. Subtract the sale price from the normal price.
$1000 - $850 = $150.
2. Divide this amount by the original price.
$150/$1000 = 0.15
3. Multiply by 100 to get the %.
0.15 x 100 = 15%
Annabeth has $29.00 to spend at the sporting goods store. She buys a T-shirt that costs $15.32. She also wants to buy a soccer ball for $12.87, a baseball cap for $8.39, a set of shin guards for $14.98, or a water bottle for $5.93. Use the equation $15.32 + c = $29.00, where c is the item cost, to select the most expensive item she can buy. A. 00:00 soccer ball B. 00:00 baseball cap C. 00:00 shin guards D. 00:00 water bottle
Answer:
B. Baseball cap
Step-by-step explanation:
Given that:
Total money available with Annabeth = $29.00
Amount at which T-shirt was bought = $15.32
Things that Annabeth wants to buy:
Soccer ball for the price of $12.87 or
Baseball cap for the price of $8.39 or
Set of shin guards for the price of $14.98 or
Water bottle for the price of $5.93
The equation that can be used to find the cost of most expensive item with the remaining amount of money:
$15.32 + [tex]c[/tex] = $29.00
[tex]\Rightarrow c = 29 - 15.32\\\Rightarrow c= \$13.68[/tex]
Cost of items that can be bought in the decreasing order is:
Cost of pair of shin guards ( $14.98 ) > Cost of soccer ball ( $12.87 ) > Cost of baseball cap ($8.39) > Cost of water bottle ( $5.93 )
The most expensive item that can be bought is the Soccer ball at $12.87.
Answer is:
B. Soccer ball
Cost of shin guards is more than the amount of money remaining.

Answer:
A = 60 degrees
C = 8 m
Step-by-step explanation:
Whenever we are faced with a geometry problem, and we have a right-angled triangle within the problem, we are to remember Pythagoras' Law first, and the fact that a right-angled triangle always has an angle that measures 90 degrees.
We will also need to know that the sum of the angles in a triangle is 180 degrees.
Therefore, angle A will be = 180 - (90 +30) = 60 degrees
From Pythagoras' Law, we can see that [tex]c= tan 30 \times 8\sqrt{3} =8[/tex]
therefore, line c = 8m

Answer: See explanation
Step-by-step explanation:
From the question, we are informed that a coach has 17 pompoms to give to her cheerleading team and that each cheerleader needs 2 pompoms to compete.
The greatest number of cheerleaders that can compete will be calculated as:
= 17 / 2
= 8 1/2
Therefore, the greatest number of cheerleader is 8.
There be 1 pompom remaining.

Answer:

3(x-y) / 2 =9
so first you have to make the equation equal to 0 so you can find the intercepts
3(x-y) /2 -9 =0
now simplify
3x-3y/2 -9 =0
2(3x-3y/2 -9)=0(2)
3x-3y-18
we will factor
3(x-y-6)
3=0
(x-y-6)=0
make the x=0 to find y and vise versa
(-y-6)=0
-y=6
y=6/-1 or -6
(x-6)=0
x=6/1 or 6
2/3x +4(y-2)=0
it is already equal to 0 to we simplify and factor
3(2/3x = 4(y-2)= 0(3)
2x+ 4y -8
2(x+y-4)
2=0
as we did in the last problem make x=0 then do the same to y
(y-4)=0
y=4
(x-4)=0
x=4

The kinetic energy of a body of mass 2 kg is 25 J. Its speed is??
Step-by-step explanation:
Kinetic Energy (K. E) = 25 J
Mass ( m) = 2 kg
Velocity or speed (v) = ?
We have the formula that
[tex]ke \: = \frac{1}{2} m {v}^{2} \\ or \: 25 = \frac{1}{2} \times 2 \times {v}^{2} \\ or \: 25 = {v}^{2} \\ or \: {5}^{2} = {v}^{2} \\ therefore \: v \: = 5 \: m |s[/tex]
it's speed is 5 m/s .
Hope it helps. :)
The speed of the body is 5 m/s
Applying the formular of kinetic energy
Kinetic energy: This can be defined as the energy posses by a moving body or that depends on the speed of a body.
The formular for kinetic energy is
E = mv²/2.................... Equation 1
Where E = Kinetic energy of the body, m = mass of the body, v = veocity/ speed of the body.
make v the subject of equation 1 above
v = [tex]\sqrt{2E/m}[/tex]................ Equation 2
From the question,
Given: E = 25 J, m = 2 kg
Substitute these values into equation 2
v = [tex]\sqrt{2*25/2}[/tex]
v = [tex]\sqrt{50/2}[/tex]
v = [tex]\sqrt{25}[/tex]
v = 5 m/s.
Thus, the speed of the body is 5 m/s

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−1 intersect are the solutions of the equation 4x = 2x−1. (4 points)
Part B: Make tables to find the solution to 4x = 2x−1. Take the integer values of x between −4 and 4. (4 points)
Part C: How can you solve the equation 4x = 2x−1 graphically? (2 points)
(10 points)
Answer:
Part A: So the solution for 4 = 2x-1 is -2. Why they're intersecting is because x is -0.5 in both cases. 2/4, as we already know, is 0.5. Since, this -2/4, we can just make 0.5 negative, so -0.5. -0.5 times 4 = -2, so x is -0.5. For y = 2x-1, multiply -0.5 by 2, which would get you -1. Then after that subtract 1, for -2.
Part B:
Well, notice how none of the entries for y = 4x and y = 2x-1 match. That would mean the answer wouldn't be an integer. (Attachment is the table)
Part C:
First, graph both y = 4x and y = 2x-1. After that, find where the two equations' y-coordinates are the same (So, on a graph, where they intersect.). The y-coordinate in common is your answer.
Answer:
A: the intersection represents the answer because the place where it intersects is where the equations have the same x values.
B: they intersect at the point (0,1)
C: plot the equations on an online graph and solve, Its almost impossible to draw an accurate continuing graph for an exponential equation. I recommend desmos.

Brandy only has $23 in cash to spend on drinks, and the concession stand charges $3.75
for a drink. If x represents the number of drinks purchased, and y is the amount of money
spent on drinks, what is the range in this situation?
Answer:
{0, 3.75, 7.5, 11.25, 15, 18.75, 22.5}
Step-by-step explanation:
Since the values in this function cannot go on infinitely this is a discrete funciton.
Its basically asking how much he can spend on drinks with 23$ if they are each 3.75$, this means that he can buy at most 6 drinks. Imagine a disctrete graph with a point on every value he spends per drink, (0,0) (1 , 3.75) (2 , 7.5) etc.
As our bright fellow shadow188 has stated, y is the range or the output so you list the possible outputs for the range in bracets.
I hope you found this helpful, ik its a little late.
The required range will be $3.75 ≤ y ≤ $23 for the function.
Given that,
Brandy only has $23 in cash to spend on drinks, and the concession stand charges $3.75 for a drink.
x represents the number of drinks purchased, and y is the amount of money spent on drinks, what is the range in this situation is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Let the x be the cost of the drink and y be the total amount of money spent,
Since there are concession stand charges of $3.75 also.
So the minimum charge will be $3.75 whether bought the drink or not, and Brandy has $23 to spend on drinks so the maximum will be $23.
So, the range can be given as $3.75 ≤ y ≤ $23.
Thus, the required range will be $3.75 ≤ y ≤ $23 for the function.

Find the domain and range of the function
Answer:
domain: (-∞ , ∞)
range: (-∞, 2]
Step-by-step explanation:
the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2
range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.
