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
Answer:
458/143=3.20 so it should be 3.20 hrs
It is a linear function.
y = 5x + 6
x represents the number of weeks in which she saves $05.00, y being the total amount of money she has saved in those weeks. If the rate is constant is constant (m = 5), it is linear.
