G. 72
H. 192
J.−576
K. 576

Answers

f(-3) = -8(-3)²
= -8(9)
= -72
Hence the answer is F

$f(-3)=-8\cdot(-3)^2=-8\cdot9=-72$

Answers

Total distance walked by Layla is 300 yards

Solution:

Given that,

Layla is walking in a rectangular park

She walks one side that is 50 yards and then the other side that is 120 yards

Length = 120 yards

Width = 50 yards

Layla develops a cramp in her leg and walks diagonally through the park to head back home

Let us find the length of diagonal of rectangle

$d=√(w^2+l^2)$

$d = √(50^2+120^2)\n\nd = √(2500+14400)\n\nd = √(16900)\n\nd = 130$

Thus length of diagonal is 130 yards

What is the total distance that layla walked?

Given that Final answer is perimeter of the triangle park

The diagonal and length and width forms a right angle triangle

Perimeter of triangle = diagonal length + width + length

Perimeter of triangle = 130 + 50 + 120 = 300

Thus total distance walked by Layla is 300 yards

Which is f(-3) for quadratic function graphed

Answers

At f(-3) the graph is equal to -9.

In order to find the point on the graph, move over to -3 on the x axis. Then move down to find the point where it hits the parabola. You'll see that the parabola hits at point (-3, -9).

Estimate the sum to the nearest whole number

29.1 +78.9 + 41.5

Answers

I rounded each number to the nearest whole number and added those.

29 + 79 + 42 = 150

If you add the original numbers you would get 149.5, which rounds to 150.

when you estimate the sum to the nearest you add one number if the decimal is over 5. 29+79+42 = 150

What is Measurement unit?

A measurement unit is a standard quality used to express a physical quantity.

Given that;

Five years ago, an alligator was 2 1/6 feet long.

Today the alligator is three times longer.

Now,

Today the height of alligator = 3 × 2 1/6

= 3 × 13/6

= 13/2

= 6 1/2

Thus, Today the height of the alligator will be 6 1/2 feet.
