Step-by-step explanation:
comvert units into one unit
4ft 2in = 4 + 2/12 ft
3ft 4in = 3ft + 4/12ft
Know that the ratio of tan(x) = O / A
and set up proportions
solve for h
1 meter is 100 cm so that means 70 cm is 70% of a meter
Answer:
f(-2) = 4
Step-by-step explanation:
The function has three definitions depending on the value of x.
You are looking for the value of the function at x = -2.
-2 is in the interval x <= -1, which is the first line of the definition of the function.
We use the first line of the definition of the function.
f(x) = -2x for x <= -1
f(-2) = -2(-2) = 4
Answer: f(-2) = 4
Let length of the hypotenuse = 3x and length of given leg be x feet.
then (3x)^2 = x^2 + 648
8x^2 = 648
x^2 = 81
so x = 9 and 3x = 27
Hypotenuse is 27 feet and the leg equals 9 feet.
