Answer:

8 ft.

Step-by-step explanation:

The formula for area of a square is:

$A=s^2$

We are given the area of 64 square feet.

$64=s^2\\\\\sqrt{64}=\sqrt{s^2}\\\\ \boxed{8=s}$

Each side should be 8 ft.

Hope this helps.

What is 9 1/10 - 4 3/4

Nady [450]

Answer:

$\frac{87}{20}$

Step-by-step explanation:

First we need to change the mixed numbers into improper fractions.

9 x 10 = 90 + 1 = 91/10

4 x 4 = 16 + 3 = 19/4

Now we need to get them into simplest terms. There is a few ways to do this, but I know that 10 x 2 = 20 and 4 x 5 = 20 so I will use 20.

$\frac{91}{10} = \frac{91 x 2}{10 x 2} = \frac{182}{20}$

$\frac{19}{4} = \frac{19 x 5}{4 x 5} = \frac{95}{20}$

Now we can subtract:

$\frac{182}{20} - \frac{95}{20} = \frac{87}{20}$

And that leaves us with our answer :D

$y = 4^x \quad \to\quad y = - \frac 2 3 (4^{x+7}) - 5$

$y=4^x$

OK, we'll go in steps. First a reflection through the x axis, which negates y.

$y = -4^x$

Now a vertical scaling of 2/3

$y = -\frac 2 3 \cdot 4^x$

Now we shift seven units to the right,

$y = -\frac 2 3 \cdot 4^{x+7}$

Now down five,

$y = -\frac 2 3 \cdot 4^{x+7} - 5$

There it is.

Answer: reflection thru x axis, vertical scale 2/3, right shift 7, down 5, second choice
