Step-by-step explanation:
F = 18 ft.
The law of cosines states
c² = a² + b² - 2ab cos C
Using our information, we have
c² = 23² + 16² - 2(23)(16)cos 52
c² = 529 + 256 - 736cos 52
c² = 785 - 736cos 52
c² = 331.8732
Taking the square root of both sides, we have
c = √331.8732 = 18.22 ≈ 18
Answer:
actual length = 171.67 ft.
Step-by-step explanation:
scale of school bus drawing is 12 in. to 5 ft.
if the length of a school bus drawing is 412 in.
5 ft
the actual length is = 412 in x --------
12 in
actual length = 171.67 ft.
present value of annuity = annual payment * [ 1 - (1+i)^-n ]/i
=>
12500 = 128.04 * [1-(1+9%/12^-n]/9%/12
=>n = 42 payments
