Tanα=h/x
x=h/tanα
x=70/tan38 ft
x≈89.6 ft (to nearest tenth of a foot)
Note: the question seems strange, (because this would make the ladder almost 114 feet long!) or are we to assume as I did that the ladder is leaning against a point 70 feet high, or should if be a 70 foot ladder leaning against a wall of unknown height?
If it is just a 70 ft ladder at a 38° inclination the:
cosα=x/L
x=Lcosα
x=70cos38° ft
x≈55.2 ft

Step-by-step explanation:
Answer:
after 4 months $8352.96
AFTER 13 MONTH $7426.507
AFTER 23 MONTH A = 7675.69
Step-by-step explanation:
Given data:
P = $9388.81
Compound interest cab be determined as
A = P( 1+ r/n)^(nt)
after 4 months

A = 9513.58
But he has to pay $1160.62 after 4 month so remaining amount is
P = 9513.58 - 1160.62 = $8352.96
AFTER 13 MONTH, so total time is 9 month

A = 8604.79
But he has to pay $1178.29 after 13 month so remaining amount is
P = 8604.79 - 1178.28 = $7426.507
AFTER 23 MONTH so total time is 10 month

A = 7675.69
Answer:
Discontinuity of function occurs when x = 4 or x = -4
zero of function is when x=0
Step-by-step explanation:
We are given:

Discontinuity of the function occur when the denominator is equal to zero.
So, we need to find the values of x that makes the denominator zero.
The denominator is x^2 - 16
x^2 - 16 =0
x^2 = 16
x = ± 4
So, if the value of x = 4 or value of x=-4 then the function will be discontinuous.
Zero of the function i.e f(x)=0
So, Putting the function equal to zero and finding the value of x

So, zero of function is when x=0
