Answer:
a 10d
Step-by-step explanation:
5d(7-3)- 16d+3*2d
Simplify what is inside the parenthesis first PEMDAS
5d(4) -16d +3*2d
Then we multiply and divide from left to right
5d(4) -16d +3*2d
20d -16d +3*2d
20d -16d+6d
Then we add and subtract from left to right
4d+6d
10d
There's an identity
sec^2 x = 1 + tan^2 x
so here we have
sec^2 theta = 1 + (3/8)^2 = 73/64
sec theta = sqrt 73 / 8 or 1.068 to nearest thousandth
Answer:
x = -2-y
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
Circle with centre (0,2) will have the equation
(x)²+(y-2)² = r²
Finding r² by distance formula using P(-7,2)
r² = (-7-0)²+(2-2)²
r² = (-7)²
r² = 49
So substituting in the equation
x²+(y-2)² = 49
