Answer:
.5 (1/2)
Step-by-step explanation:
First you need to solve the equation and find its answer. In this case, 4x+1=3 would equal 1/2 (in this case it'll be .5) Then you need to figure out how far it is from 0. Which is easy, since absolute value is always positive. Your answer will be .5
24 slices because you would do three apples times eight slices so you would get 24 slices
Recall the double-angle identity,
sin²(<em>x</em>) = (1 - cos(2<em>x</em>)) / 2
Now if sin(12°) = <em>k</em>, then
<em>k</em> ² = sin²(12°) = (1 - cos(24°)) / 2
→ cos(24°) = 1 - 2<em>k</em> ²
Answer:
21 performances
Step-by-step explanation:
First, you have to subtract 150-24 (to find the total amount of time the performances will take), which is 126
Next, you divide 126/6 (each performer has 6 minutes), which is 21
so the talent show can accommodate 21 performers
