Answer:
A: f(x)=10cos(2π/5 x)+10
Step-by-step explanation:
The coefficient of x in the cosine argument of the function will be 2π/period. Since the period is 5, the coefficient is 2π/5. This observation eliminates choices B and C.
The description "not a reflection of the parent function over the x-axis" means the multiplier of the cosine function is not negative, eliminating choice D.
The remaining choice A matches the description.
Answer:
(69)(3)−8
=
15
199≠15
False
Step-by-step explanation:
hope it helps, 69(3) is already bigger than 15, then -8 makes it 199, which is definitely not equal to 15.
75 cents = $0.75
1 day = 24 h
$0.75 · 24 = $18
<span>Answer: 75 cents/h = </span><span>18 dollars/day </span>
Answer:
less than 55 minutes
Step-by-step explanation:
11 laps at 5 minutes per lap is 55 minutes.
Since she will run fewer than 11 laps, she will run less than 55 minutes.
Answer:
y=4x
Step-by-step explanation:
The equation of a line is y=mx+b, where m is the slope and b is the y intercept.
The slope formula is Δy/Δx, so using the coordinates (1, 4) and (2, 8), the slope is 
which equals 4.
The y intercept is 0.
Therefore, the equation is y=4x.
