I hope this helps you

f (7)=7^2+6

f (7)=49+6

f (7)=55

g (f (7))=g (55)=55+8/55

g (55)=63/55

Base on the given values above, here is how we found the correct answer.
At first, what we need to do is to evaluate x first. (g ° f)(–7) is equal to <span>g(f(-7)). So x = -7. So now, plug in the values:
</span>f (7)=7^2+6
f (7)=49+6
f (7)=55
g (f (7))=g (55)=55+8/55
g (55)=63/55
So the answer would be 63/55.
Hope this answer helps.

The amount $180.00 is what percent greater than $135.00?

svp [43]

It would be: 180/135 * 100 = 36/27 * 100
= 4/3 * 100
= 400/3 = 133.33

It means, 180 is 133.33% of 135. So, the difference would be: 133.33 - 100 = 33.33%

In short, Your Final Answer would be 33.33%

Hope this helps!

Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 50 meters. What is the diagonal d

jolli1 [7]

Answer:

70.7 meters.

Step-by-step explanation:

We have been given that Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 50 meters.

Since we know that diagonal of a square is product of side length of square and $\sqrt{2}$ . So we will find diagonal of our given square plaza by multiplying 50 by $\sqrt{2}$ .

$\text{Diagonal distance across the plaza}=50\times \sqrt{2}$

$\text{Diagonal distance across the plaza}=50\times 1.414213562373095$

$\text{Diagonal distance across the plaza}=70.71067811865475\approx 70.7$

Therefore, diagonal distance across the plaza is 70.7 meters.
