The equation of a circle that contains the point (–5, -3) and has a center at (-2, 1) is (x + 2)² + (y - 1)² = 25
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The circle contains the point (–5, -3) and has a center at (-2, 1), hence:
The equation is:
(x - (-2))² + (y - 1)² = 5²
(x + 2)² + (y - 1)² = 25

Answer:
A) 300 cm2
Step-by-step explanation:
First you have to find height
use Pythagorean theorem: a2 + b2 = c2
h2 + 64 =289
h2 = 289-64
h2 = 225
h= 15
now the area
A = a * h
A = 20 * 15
A = 300 cm2
Answer:
0.05?
Step-by-step explanation:
0.2 are taken by oarents
3/4 = 0.75 were taken by parents
0.20 + 0.75 = 0.95
1.00 - 0.95 = 0.05
Answer:
30
Step-by-step explanation:
A triangle has a total degree of 180. We already have 150(from the 60 and the right angle) 180-150 is 30
