Answer:

d.

Step-by-step explanation:

\bigg( \frac{16}{49}  \bigg)^{  - \frac{3}{2} }  \\  \\  =  \bigg( \frac{49}{16}  \bigg)^{ \frac{3}{2} }  \\  \\  =  \bigg( \frac{ {7}^{2} }{ {4}^{2} }  \bigg)^{ \frac{3}{2} }  \\  \\  =  \bigg( \frac{ {7}}{ {4} }  \bigg)^{ \frac{2 \times 3}{2} }  \\  \\  =  \bigg( \frac{ {7}}{ {4} }  \bigg)^{ 3}   \\  \\  =  \frac{343}{64}  \\

The figure shows a carpeted room. How many square feet of the room are carpeted?
OverLord2011 [107]

Split the figure into two shapes.

Top rectangle would be 6 feet x 5 feet ( 8-3)

The bottom rectangle would be 2 feet x 3 feet.

Calculate the area of both and add them together:

6 x 5 = 30

2 x 3 = 6

Total area = 30 + 6 = 36 square feet.

Which of the following exponential regression equations best fits the data shown below
Art [367]

Answer:

(D) 8.46\cdot 3.51^x

Step-by-step explanation:

One could run this on a computer and verify the best fit through brute force. The more elegant way is, as usual, to think: What are special values of x for an exponential function? Zero, for starters - anything to the power of zero is 1. The function value for x=0 in the table is 10. Which choices A through D are close to 10 for x=0? Well, (C) and (D), the rest is too far. Next, what is the function value for the next easy one, x=1? The table says 30. Which of (C) and (D) is close to 30 for x = 1. It turns out we can safely exclude (C) because 10.84*1.77 is about 19 and that's way too far from 30. Let's check (D): 8.46*3.51=29.7 - that's quite close. Since there is no other candidate left, I bet my money on (D). Feel free to verify closeness for the other values of x if you are unconvinced yet.
