Answer:
32d
Step-by-step explanation:
-The students ride their bikes to and from school every day. The distance is thus;

-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:

Now, we multiply the distance per day by the total number of days:

Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).
First we need to find the length and width of the rectangle.
As seen from the graph, the length is 4 units and the width of rectangle is 3 units. The triangle ABD is a Right Angled Triangle with side BD as the diagonal. BD is also the hypotenuse of the Right Angled Triangle, so we can find its length using the Pythagorean Theorem.
Using the theorem we can write:
Therefore, the diagonal of the rectangle will be 5 units long.So, the answer is option C
Answer:
Yes, this is a function
Step-by-step explanation:
You know this because it passes the vertical line test.
I hope this helps!
(gof)(3) = g(f(3))
so
f(3) = -2(3) + 8 = 2
g(f(3)) = 5(2) = 10
answer
C. 10
