Radius = 7
center = (-3, 1)
Equation for a circle is: r² = (x-h)² + (y-k)²
where r = radius, (h,k) = center
fill in the values to get:
7² = (x+3)² + (y-1)²
Answer is C
Answer:
$2.80
Step-by-step explanation:
8x0.35=$2.80
So evaluate/subsitue
the equation becomes
(78 times 91+42)^2
pemdas
do what's inside the parenthasees first
start over
parenthasees
exponents
multiplication and division yes 78 times 91
addition and subtraction so
78 times 91 is first
78 times 91=7098
addition
(7098+42)^2
(7140)^2
restart
parentasees simplified
exponents
7140^2=50,979,600
