Answer: 88
Step-by-step explanation: since its a circle u times the diameter of the cloth by 3.14 which is 87.92 so you round it to 88
Answer:
Step-by-step explanation:
Given
f(x) = 2x^2 - 3x
g(x) = -2x + 4
Now
f(-5) = 2 *(-5)^2 - 3*(-5)
= 2 * 25 + 15
= 50 + 15
= 65
Also
g(5) = - 2 * 5 +4
= -10 +4
= - 6
Hope it will help you.
Answer:
1.38
Step-by-step explanation:
tan Ø = 2/3
Ø = tan⁻¹(2/3)
Ø = 33.69
sin 33.69 ≈ 0.55
cos 33.69 ≈ 0.83
sin Ø + cos Ø ≈ 1.38
<span>y = 5/6x - 12
when x = 12
</span>y = 5/6x - 12 = 5/6(12) - 12 = 10 - 12 = -2
(12, -2)
answer is D. <span>y = 5/6x - 12</span>
