Step-by-step explanation:
It is given that, Antonio can run a mile in 6.5 minutes. We need to find for how many minutes will it take him to run 4.25 miles. It can be calculated using unitary method.
1 mile = 6.5 minutes
Let t is the time taken by Antonio to run 4.25 miles.
So, 27.62 minutes is taken by Antonio to cover 4.25 miles. Hence, this is the required solution.
Given function : .
We need to find the values of f(-2).
In order to find the value of f(-2), we need to plug x=-2 in the given fucntion .
Replacing x by -2, we get
We get (-2)^2 = -2 *-2*-2=-8 and (-2)^2 = -2 * -2 = 4.
.
f(-2) = -160 +12.
f(-2) = -148.
Therefore, correct option would be option D. That is f(-2)=-148.
Answer:
Part 1) The lateral area is
Part 2) The area of the two bases together is
Part 3) The surface area is
Step-by-step explanation:
Part 1) Find the lateral area
we know that
The lateral area of a prism is given by
where
P is the perimeter of the base
h is the height of the prism
so
----> perimeter of rectangle
---> given
substitute
Part 2) The area of the two bases together is?
The area of the rectangular base B is equal to
therefore
The area of the two bases together is
Part 3) The total surface area is
we know that
The surface area is equal to
substitute
