Vertical angles are congruent, so
107=3x-4
3x=111
x=111/3=37°
Answer:
C. $7.70
Step-by-step explanation:
First, you have to calculate the 10% of the price and subtract that from the price to find the amount of the discount:
$27*10%=$2.7
Now, you can add the amount of the discount plus the coupon to find the amount that the customer saved:
$5+$2.7=$7.7
According to this, the answer is that the customer saved: C. $7.70

Answer: y = 6 cos (2x) + 4
<u>Step-by-step explanation:</u>
A cosine function is expressed as: y = A cos (Bx - C) + D where
- amplitude (A) is the distance from the midline to the max/min.
- B = 2π/P where P is the period
- C/B is the phase shift
- D is the center line (aka midline)
A = Max - Midline
= 10 - 4
= 6
The max to the midpoint is π/4
⇒ 1/4 P = π/4
⇒ P = π
B = 2π/P
= 2π/π
= 2
C = 0 because there is no phase shift
D = 4 (given)
Input A = 6, B = 2, C = 0, and D = 4 into the cosine function:
y = 2 cos (2x - 0) + 4
Number 1 is D, and number 2 is B.
