To get the answer, multiple 20 by 0.45= $9 than subtract 9$ from $10 which equals $1.
Answer:
√6 + √2
= --------------
4
Step-by-step explanation:
15° = 45° - 30°
So
cos(15) = cos(45 - 30)
=cos(45) × cos(30) + sin(45) × sin(30)
= 1/√2 × (√3)/2 + 1/√2 × 1/2
(√3) + 1
= --------------
2√2
(√3) + 1 √2
= -------------- x ---------
2√2 √2
√6 + √2
= --------------

Answer:
I figured all these out by graphing the function. See the attachment for a picture.
h(x) = (x-1)^2
It's <u>increasing over (1, ∞)</u> because the values are going up in that span.
It's <u>decreasing over (-∞, 1)</u> because the values are going down in that span.
Its range is all values of <u>y </u>
<u> 0</u> (we can see that only y-values above 0 are in the function).
g(x) = -(x+1)(x-1)
It's <u>increasing over (-∞, 0)</u> because the values are going up in that span.
It's <u>decreasing over (0, ∞)</u> because the values are going down in that span.
Its range is all values of <u>y </u>
<u> -1</u> (we can see that only y-values below 1 are in the function).
