Answer:
6miles/hour
Step-by-step explanation:
Speed = Distance/time
So speed is: 
You will get 6/2 from this so you get 6miles/hour

The area of the semicircle
First, we calculate the hypotenuse (h) of the triangle
Considering only the triangle, we have:
--- cosine formula
Make h the subject



The area of the semicircle is then calculated as:

This gives:



Answer:
the ratio would be 2:3 simplified
Answer:
x = - 9 , 6
Step-by-step explanation:
The given function is
⇒
Therefore, the value of h(x) will be undefined for the denominator equal to zero.
So, (x + 9)(x - 6) = 0
⇒ x = - 9 and x = 6
Therefore, the values of x which are not in domain of function h(x) are x = - 9 , 6. (Answer)
Log (25¹/⁵) = (1/5) log(25) = (1/5) (1.3979) = 0.2796
