Answer:
5.5 minutes
Step-by-step explanation:
Fill in the given information and solve for t.
75 = -15cos(2πt/15) +65
-10/15 = cos(2πt/15)
t = 15/(2π)arccos(-2/3) ≈ 5.492
The volume reaches 75 dB about 5.5 minutes after the truck arrives.
Given:
The diagram of a circle.
.
To find:
The measure of arc BEF.
Solution:
The measure of central angle is equal to the measure of corresponding arc.
So, in the given figure,
Now,
Therefore, the measure of arc BEF is 230 degrees.
Answer:
y = -2x + 11
Step-by-step explanation:
Slope point equation:
y - y1 = m(x -x1)
y1 = 7 ; x1 = 7 , m = -2
y - 7 = -2(x - 2)
y - 7 = -2x -2*(-2)
y -7 = -2x + 4
y = -2x + 4 + 7
y = -2x + 11
