Keisha swims 18 feet from one side of her circular pool to the other swimming straight through the center. She then swims one ti

Ket [755]

Answer:

56.5 ft

Step-by-step explanation:

Here we know that:

- Keisha swims 18 feet from one side of her circular pool to the other swimming straight through the center --> this means that the diameter of the swimming pool is 18 feet, so

d = 18 ft

- Then, she swims one time around the entire edge of her swimming pool. --> this means that she swims along the perimeter of the swimming pool

The perimeter of a circle is given by

$p=\pi d$

where d is the diameter. Therefore in this case, the length of Keisha's second swim is:

$p=\pi \cdot d = 3.14 \cdot 18 =56.5 ft$

What are the factors of x^2-144?

Ksju [112]

Answer:

(x-12) (x+12)

Step-by-step explanation:

If you factor it out since both are perfect squares you would place an x on each side and then find the square root of 144, which is 12 and put a positive and a negative in each parenthesis.

What’s the x and y intercept of 8x+5y=-48

Anuta_ua [19.1K]

Step-by-step explanation:

$8x + 5y = - 48 \\ \\ at \: x = 0 \\ \\ 8 \times 0 + 5y = - 48 \\ \\ \therefore \: 5y = - 48 \\ \\ \therefore \: y = \frac{ - 48}{5} \\ \\ \therefore \: y - intercept = - 9.6 \\ \\ at \: y = 0 \\ \\ 8 x + 5 \times 0 = - 48 \\ \\ \therefore \:8x = - 48 \\ \\ \therefore \: x = \frac{ - 48}{8} \\ \\ \therefore \: x - intercept = -6 \\ \\$
