Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]\frac{27}{32}[/tex] × [tex]\frac{16}{27}[/tex] ← cancel the 27 and 16, 32 by 16
= [tex]\frac{1}{2}[/tex]
A 2-column table has 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled y with entries 4.5, 6.75, 10.125, 15.1875.
What is the multiplicative rate of change of the exponential function represented in the table?
1.5
2.25
3.0
4.5
The multiplicative rate of change of the exponential function represented in the table is 1.5.
Option A is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find the multiplicative rate of change of the exponential function represented in the table, we need to look at the ratio of consecutive
y-values.
The first ratio is:
6.75 / 4.5 = 1.5
The second ratio is:
10.125 / 6.75 = 1.5
The third ratio is:
15.1875 / 10.125 = 1.5
Since all three ratios are the same, we can conclude that the function is exponential with a constant multiplicative rate of change equal to 1.5.
Therefore,
The multiplicative rate of change of the exponential function represented in the table is 1.5.

Answer:
a) -1535.5
b) 0
Step-by-step explanation:
A) We do this problem according to its parenthesis. First, let's evaluate the first half, -2[(-1/4)-12(-1)^2]. We have to do (-1)^2 first, because of PEMDAS. (-1)^2 is just 1. Now, our equation is -2[(-1/4)-12*1]. Thus, we get -2[(-1/4)-12] because 12*1 is just 12. Then, we do (-1/4)-12, giving us -12.25. Our equation becomes -2(-12.25). Then, we just get 24.5.
The next half, -5[24+2(-12)^2] is similar. We first evaulate (-12)^2 because of PEMDAS, giving us 144. Then, we have -5[24+2(144)]. 2 times 144 is 288, so we get -5[24+288]. 24 + 288 is 312, so we have -5(312). This finally gives us -1560.
Putting the two together, we get 24.5 - 1560, which is -1535.5.
--------------------------------------------------------------------------------------------------------------B) We substitute a = -1/3 and b = -1 into the equation, -a^2b^2 - 3a^3b^2.
We plug in -1/3 where a is and -1 where b is. So:
-(-1/3)^2(-1)^2 - 3(-1/3)^3(-1)^2.
The tricky part of this problem is making sure you follow PEMDAS. We evaluate the exponents first.

Dace Slide
Students, draw anywhere on this slide!
Answer:
B
Step-by-step explanation:
We can subtract the fixed 12 of 40 to see how much she can spend on messages alone. So we are left with $28.
At 10 cents apiece for every dollar she can send 10. So we would get 280 messages.
I dont understand the options given, I think there are equation signs missing
So it would be B I assume since x=280

Use the value 3.14 for it, and do not round your answer.
Be sure to include the correct unit in your answer.
PLZZ HELP I WILL MARK BRAINLIEST!!
Answer:
113.04 cm.
Step-by-step explanation:
Step 1: Formula/explain
To find the area of a circle, multiply the radius by itself twice, then multiply the product pi.
[tex]a=\pi r^2(3.14*radius*radius)[/tex]
Step 2: Solve
According to the word problem, the circle has a diameter of 12. This means it has a radius of 6.
Now, we plug the numbers into formula.
[tex]\pi 6^2 (3.14*6*6)=113.04[/tex]
Step 3: Conclude
Therefore, the area of this circle is 113.04 cm.

HELP DUE IN 10 MINS!
Given that QUAD is a rectangle, QS = 17, and QD = 16 find the length of DU and QU.
DU =??
QU =??
Answer:
DU = 34
QU = 30
Step-by-step explanation:
DU = 34 since the diagonals of a rectangle are congruent, Diagonal QA would be 17 * 2 and so would be Diagonal DU.
QU = 33.045, according to me the base of a triangle;
b = [tex]2\sqrt{l^2-h^2}[/tex], height would be half the length of QD = 8
b = 2[tex]\sqrt{17^2 -8^2}[/tex]
b = 30
Hope this helps!
