3/4 times 60 = 45
45 mph is the answer
Answer:
True
Step-by-step explanation:
Quadratic functions are functions that have a leading degree of 2. The values when the icicle starts and stops dripping is at x = 2 and 9
<h3>Application of intercepts of a function</h3>
Quadratic functions are functions that have a leading degree of 2.
Given the equation that represents the rate at which an icicle drips below:
f(x) = −x^2 + 11x − 18
If the icicle is not dripping at the point where f(x) is a negative number, hence point where the icicle starts and stops dripping is the point where f(x) =0
Substitute
−x^2 + 11x − 18 = 0
x^2 - 11x + 18 = 0
x^2 - 9x - 2x + 18 =0
x(x - 9)-2(x-9) = 0
x = 2 and 9
Hence the values when the icicle starts and stops dripping is at x = 2 and 9

#SPJ4
Answer:
x = 65
Step-by-step explanation:
Since we know the bottom line is = 180 (since it shows the top line)
The angle to the left of x is 90, which leaves x + 25 = 90
x = 65
