Area of a circle= 2 times pi times radius squared
A= 2 <span>π r^2
A=2(3.14)(97mm)^2= 609.16 mm^2</span>
7x- y = 17 is the standard form
Hello from MrBillDoesMath!
Answer:
10
Discussion:
(g-f)(5) =
g(5) - f(5) =
(2(5)+13) - (5^2-12) = => as 5^2 = 25
(10+13) - (25-12) =
23 - 13 =
10
Thank you,

Answer:
153 degrees is the measure of the supplementary angle
<span>Replace tan θ with sin θ/cos θ
= sin²θ/cos θ + cos θ
Now multiply the right-hand side by cos θ/cos θ to get the same denominator:
= sin²θ/cos θ + cos²θ/cos θ
= (sin²θ + cos²θ)/cos θ
The numerator is equivalent to 1:
= 1 / cos θ
= sec θ</span>
