The answer would be 656.

Extracting the root is the inverse operation of ^2:

<span><span>656<span>−−−</span>√2</span>×<span>656<span>−−−</span>√2</span>=<span><span>656<span>−−−</span>√2</span>2</span>=656</span>

The term can be written as

<span><span>656<span>−−−</span>√</span>or<span>656<span>−−−</span>√2</span></span>

Like any positive number, the number 656 has two square roots: <span>656<span>−−−</span>√2</span>

, which is positive and called principal square root of 656, and −<span>656<span>−−−</span>√2</span>

, which is negative.

Together, they are denominated as ± <span>656<span>−−−</span>√2</span>

.Hope this helps!!

20. What is the equation of the line that passes through the points (–2, 2) and (0, 5)? A. y = x + 5 B. y = x – 5 C. y = –3/2x +
Vanyuwa [196]

y=mx+b

first find the y intercept or b or x=0

b=5

now find the slope

y²-y¹/x²-x¹--> 5-2/0-(-2)

m=3/2

the equation is D. y=3/2x+5

Find the formula for the area A and the perimeter P of the shape shown find the area and perimeter when R is 5 cm find R when A
Ghella [55]

Answer:

1)Area; A = ¼πr²

Perimeter; P = πr/2 + 2r

2)A = 19.63 cm²

P = 17.85 cm

3) r = 8.885 cm

4) r = 14 cm

Step-by-step explanation:

This is a quadrant of a circle. Thus;

Area of a circle is πr². A quadrant is a quarter of a circle. Thus;

Formula for Quadrant Area is; A = ¼πr²

A) Perimeter of a circle is 2πr. Thus, perimeter of a quadrant is a quarter of the full circle perimeter.

Formula for the quadrant perimeter in the image given is;

P = 2πr/4 + 2r

P = πr/2 + 2r

B) When r is 5 cm;

A = ¼π(5)²

A = 19.63 cm²

P = π(5)/2 + 2(5)

P = 17.85 cm

C) when A is 100cm²:

¼πr² = 100

r² = 100 × 4/π

r² = 78.9358

r = √78.9358

r = 8.885 cm

D) when P = 50 cm.

50 = πr/2 + 2r

50 = (½π + 2)r

r = 50/(½π + 2)

r = 14 cm
