Step-by-step explanation:
C=p+R x p
C=30.99 + .05 x 30.99
Order of operations states do the multiplication first
C=30.99 + 1.55
C=32.54

Answer:
h(4) = -1 ; h(-5) = 1 h(0) = -9
Step-by-step explanation:
a) h(x) = |-2x| - 9 Substitute x = 4
h(4) = | -2 · 4| - 9
h(x) = | -8| - 9
h(4) = 8 - 9
h(4) = -1
b) h(x) = |-2x| - 9 Substitute x = -5
h(-5) = |-2 · -5| - 9
h(-5) = |-10| - 9
h(-5) = 10 - 9
h(-5) = 1
c) h(x) = |-2x| - 9 Substitute x = 0
h(0) = |-2 · 0| - 9
h(0) = |0| - 9
h(0) = 0 - 9
h(0) = -9

Answer:
- 128°
- 52°
- 47°
- 133°
- 81°
Step-by-step explanation:
Alternate interior angles are congruent, so you know ...
∠2 = 52°
∠3 = 47°
The sum of angles in a triangle is 180°, so ...
∠5 = 180° -∠2 -∠3 = 180° -52° -47°
∠5 = 81°
Linear pairs are supplementary, so ...
∠1 = 180° -∠2 = 180° -52°
∠1 = 128°
∠4 = 180° -∠3 = 180° -47°
∠4 = 133°
_____
<em>Alternate solution</em>
To find angles 1 and 4, you could also make use of the fact that same-side interior angles are supplementary.
