Answer:
78.5°
Step-by-step explanation:
We solve for the above question, using the formula for the Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
Adjacent = The distance between the house and the base of the ladder = 4 feet
Hypotenuse = Length of the Ladder = 20 feet
Hence,
cos θ = 4/20
θ = arc cos(4/20)
θ = 78.463040967°
Approximately = 78.5°
Therefore, the angle that the ladder makes with the ground is 78.5°
The function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.
<h3>Exponential equation</h3>
The inverse of exponential equation is logarithmic equation. The standard exponential equation is expressed as;
y = ab^x
where
a is the initial value
b determine the growth rate or decay.
If the value if b < 1, then it is a decay otherwise it is growth.
Given the function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.

I am assuming you mean $37.52 per hour for the mechanic and $30.42 per hour for the assistant.
Simply multiply each of the hourly wages by 40 and compare the results by finding the difference.
Here:
$37.52 x 40 = $1500.80
$30.42 x 40 = $ 1216.80 When you subtract them you get $284 difference.
