Answer:
12 x 40 = 480 feet per minute.
480 x 60 = 28800 feet per hour.
28800/5280 = 5.45 miles per hour.
Hope that helps.Thank you!!!
Answer:
(f о g)(0) = 24
Step-by-step explanation:
f(x) = -5x - 1
g(x) = x² - 5
When you see (f о g)(#), they want you to plug the function g(x) into the function f(x).
First find g(0).
g(0) = (0)² - 5
g(0) = 0 - 5
g(0) = -5
Now plug g(0) = -5 into f(x) by replacing all x's with -5.
(f о g)(0) = -5(-5) - 1
Multiply.
(f о g)(0) = 25 - 1
Subtract.
(f о g)(0) = 24

Step-by-step explanation:
The given expression is
As we know that a mixed fraction
can be converted into proper or improper fraction as 
⇒ 
= 
and, 
= 
Hence, the simplified expression =

Answer:
cos M = 38 / 63
Step-by-step explanation:
SOH - CAH - TOA
is how I remember the calculations,
S - sin
C - cos
T - tan
(o = opposite side ; a = adjacent side ; h = hypotenuse)
SOH would be sin = opposite/hypotenuse
CAH means cos = adjacent / hypotenuse
Okay, so looking at the angle M, we know the hypotenuse [63] and the adjacent value [38]
From this, (only having H and A), we can only find the cos of M
(without finding additional numbers, which we could do with the Pythagorean theorem)
So, the cos of M is adjacent/hypotenuse
cos M = 38 / 63
(I didn't try to find other measurements of the triangle here because the most simple measurements [that were already there] worked/was an option)
