Your friend says that the table represents an exponential function because y is multiplied by a constant factor. Is your friend correct? Explain.
A.Yes. Because y is multiplied by a constant factor, the function is exponential.
B.Yes. Because y increases by greater amounts as x increases, the function is exponential.
C.No; Because y is multiplied by a constant factor, the function is not exponential.
D. No; Because x increases by different amounts, the function is not exponential.
x: 0,1,3,6
y: 2,10,50,250
Answer:
C.No; Because y is multiplied by a constant factor, the function is not exponential.
Step-by-step explanation:
For a set of number to be exponential, there is need for it to show a logical increase of a given time frame when the set of number is multiplied by a constant factor. In the table given, though the Y function is multiplied by a constant factor, the increase of the function is irregular so therefore cannot be said to be exponential.

One page of a petition can hold p signatures. You were able to get 4p+5 people to sign the petition. Your friend was able to get 2p−3 people to sign the petition. Write an expression in simplest form that represents the number of people that you and your friend got to sign the petition.
Answer:
6p - 2
Step-by-step explanation:
The expression that needs to be made in this question refers to the total number of people that signed the petition. To calculate this we need to add the total number of signatures that both you and your friend were able to acquire. Once we do this we simply combine like terms in order to simplify the expression as much as possible.
4p + 5 + 2p - 3
4p + 2p + 5 - 3
6p - 2
Therefore, the total and simplified expression for the total number of signatures would be 6p - 2
3x-5/6=1/6 what does x=?
Answer:
x = 2
Step-by-step explanation:
[tex]\frac{3x-5}{6} = \frac{1}{6} \\[/tex]
In order to solve this, you must get the denominator off of the left-hand side of the equation, by multiplying 6 on each side, in order to get the denominators to cancel. This leaves you with:
[tex]3x-5 = 6/6\\3x-5 = 1[/tex]
Then, you add 5 to each side.
[tex]3x = 6[/tex]
Divide by 3, to get x by itself.
[tex]x = 2[/tex]
Which gets us to our final answer of x = 2.
Then, you can plug x back into the equation just to double-check yourself:
[tex]\frac{3(2)-5}{6} = \frac{1}{6} \\\\\frac{6-5}{6} = \frac{1}{6}\\\\\frac{1}{6} = \frac{1}{6}[/tex]
I hope that this helped you understand to concept a little better. Good luck.

Answer: x⁴y²⁰
Step-by-step explanation: Distribute the exponent ⁴ over the parentheses
(x y⁴)⁴ becomes x⁴y¹⁶ (multiply exponents)
then take the 4th root of y¹⁶ (divide the exponent of the radicand by the index) ⁴√y¹⁶ becomes y⁴
Then multiply the factors. Add exponents
x⁴y¹⁶ * y⁴ becomes x⁴y²⁰

A race car can travel at a speed of 3.4 x 10^2 miles/hour. The Speed of Sound is approximately 7.6 × 10^2 miles/hour. How many times faster is the Speed of Sound than the Bullet Train?
Answer:
The speed of sound is 2.23 times of the speed of race car
Step-by-step explanation:
Given that,
The speed of a race car = [tex]3.4\times 10^2\ mi/h[/tex]
The speed of sound = [tex]7.6\times 10^2\ mi/h[/tex]
Dividing the speed of sound to the speed of a race car. So,[tex]\dfrac{\text{speed of sound}}{\text{speed of race car}}=\dfrac{7.6\times 10^2}{3.4\times 10^2}\\\\\dfrac{\text{speed of sound}}{\text{speed of race car}}=2.23[/tex]
So, the speed of sound is 2.23 times of the speed of race car.
If the cost of 4 pears and 2 peaches equals $1.00 and the cost of 2 pears and 3 peaches equals $0.70 how much does each pear and each peach cost
Answer:
20 p per pear 10p per peach
Step-by-step explanation:
Hope this helps
Answer:
1 pear costs 20 cents. 1 peach costs 10 cents.
Step-by-step explanation:
x represents pears
y represents peaches
4x + 2y = 1
2x + 3y = 0.7
multiply the second equation by -2 to elimate the x variable
(2x +3y = 0.7) -2 = -4x - 6y = -1.4
add the new equation to the first original one:
4x + 2y = 1
-4x - 6y = -1.4
-4y = -0.4. divide both sides by -4, y = 0.10
plug in y = 10, solve algebraically and get x = 0.20
Lastly, check your work:
4(0.20) + 2(0.10) = 1
2(0.20) + 3(0.10) = 0.7

What is the rate of change? I will give u a crown if ur right just help ASAP
Answer:
-2 because rise over run is -2/1 or -2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
The rate of change is the slope.
A slope that goes down to the right is negative. This line has a negative slope.
Now we will find the exact value of the slope.
slope = rise/run
rise = vertical distance (up is positive; down is negative)
run = horizontal distance (right is positive; left is negative)
Start at an easy-to-read point. Let's start at (0, 1) which is the y-intercept.
Now we need to go to another easy-to-read point. Let's use (1, -1) as our second point.
(By easy-to-read points, I mean points on grid line intersections whose coordinates can be read easily off the graph.)
We need to go from (0, 1) to (1, -1) by only moving vertically and horizontally. Start at (0, 1). We go vertically down 2 units and then horizontally right 1 unit to get to (1, -1). Going vertically down 2 units is a rise of -2. Going horizontally right 1 unit is a run of +1.
slope = rise/run = -2/1 = -2
slope = -2
The rate of change is the slope.
Answer: rate of change = -2
Deana made a scale drawing of her patio using a scale of 1/2 cm =1 foot what is the actual width, in feet, of deanas patio
Full question attached
Answer and explanation:
Given that 1/2cm= 1 foot
5cm= 2×5=10 feet
Length is twice the width, therefore real length of shape = 10×2=20 feet
Perimeter is sum of all sides= 20 feet+20 feet+10 feet+10 feet = 60 feet
Therefore Deana's Patio= 60 feet in real length
Answer:
60

What is the sum of 25% of 2018 and 2018% of 25?
Answer:
1009
Step-by-step explanation:
0,25 x 2018 = 504,5
20,18 x 25 = 504,5
504,5 + 504,5 = 1009
Answer:
1,009
Step-by-step explanation:
[tex] \frac{25}{100} \times 2018 = 504.5[/tex]
[tex] \frac{2018}{100} \times 25 = 504.5[/tex]
[tex]504.5 + 504.5 = 1009[/tex]
