11/2 divided by $0.99 is $<span>1.51</span>
Answer:
1 / 2
Step-by-step explanation:
The average rate of change is the same as the slope.
Slope formula: (y₂ - y₁) / (x₂ - x₁)
= (5 - 3) / (2 - (-2))
= 2 / 4
= 1 / 2
Answer: A right triangle.
Step-by-step explanation:
This is because an acute triangle would have all of its three sides acute while an obtuse one would have two acute angles as well, but also an obtuse one. If the question is specifically asking for a triangle with exactly two acute angles, a right triangle would be the answer.
Answer:
Below.
Step-by-step explanation:
We need to prove this identity by taking the left side and trying to transform it to the right side.
LHS = sin(150 + x) + sin(150 − x)
= sin 150 cos x + sin x cos 150 + sin 150 cos x - sin x cos 150
= 2 sin 150 cos x
= 2 * 1/2 * cos x
= cos x = RHS.
So it is proved.
|x-10| when x = -8
| - 8 - 10 | = |-18| = 18 <==
