Answer:
f ) x+72=90(complementary angle)
x= 90-72
x=18
g )x+77=90
x=90-77
x=13
plz give me thanks
Answer:
381.51 in^3
Step-by-step explanation:
Volume of a sphere = 4/3 x pi x r^3
r = 9/2 = 4.5
4/3 x 3.14 x 4.5^3 = 381.51 in^3
5x^2 + 6x +13.88 is what is is simplified hope it helped a bit
Answer:
(x + 3)² + (y -2)² = 4
Explanation:
Circle Formula: (x -h)² + (y -k)² = r²
"r" is radius, "h" is x coordinates of center, "k" is y coordinate of center.
Here given:
Insert values:
(x -(-3))² + (y -2)² = 2²
(x + 3)² + (y -2)² = 4
X6 – 9x3 + 8 = 0
let u = x^3
u^2 - 9u + 8 = 0
(u-8)(u-1) = 0
u = 1,8
back substitute
1 = x^3
8 = x^3
