A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 98m long and 76m wide. F

Vsevolod [243]

Without the image, I assume the two semicircles are on each end of the rectangle.

Rectangle; A = lw
A = 98 x 76
A = 7,448 square meters

Put the two semicircles together to form a circle; A = π $2^{2}$
A = (3.14)( $76^{2}$ )
A = 3.14 x 76 = 5,776 square meters

7,448 + 5,776 = 13,224 square meters

Which is f(5) for the function -2x2 + 2x - 3?

Schach [20]

The value of f(5) is -37

Solution:

Given function is:

$f(x) = -2x^2+2x+3$

We have to find the value of f(5)

To find the value of f(5), we have to substitute x is equal to 5 in given function

Plug in x = 5 in f(x)

$f(x) = -2x^2+2x+3\\\\f(5) = -2(5)^2+2(5) + 3\\\\\text{Simplify the above expression }\\\\f(5) = -2(25) + 10 + 3\\\\\text{Solve the above expression }\\\\f(5) = -50 + 10 + 3\\\\f(5) = -40 + 3 = -37$
