Answer:

The answer to your question is SA = 2419.34 m²

Step-by-step explanation:

Data

a = 11.42 m

side = 11 m

height = 20 m

Formula

SA = 2B + PH

Process

1.- Calculate P

Perimeter = P

P = 7(11)

= 77 m

2.- Calculate B

B = Pa/2

= (77)(11.42)/2

= 879.34/2

= 439.67 m²

3.- Calculate 2B

2B = 2(439.67)

= 879.34 m²

4.- Calculate PH

PH = (77)(20)

= 1540 m²

5.- Calculate SA

SA = 879.34 + 1540

= 2419.34 m²

Is this a linear function , why or why not ? explain y=x^2-1

kotykmax [81]

If you graph out y = x^2 - 1, you'll see that it is a curved parabola. It is not a straight line. So visually this shows the equation is not linear. It's considered nonlinear.

Algebraically, the given equation does not fit the form y = mx+b which is slope intercept form. So this is more confirmation that we do not have a linear function.

A trapezoid has a height of 6 feet. The measures of the bases are 12 units and 18

Alik [6]

The area of this trapezoid is 90 square feet.

<h3>Explanation : </h3>

Before we know the answer, let's we know the formula first. The formula for count the area of trapezoid is :

$\boxed {\bold {A = \frac {(a+b) \times h}{2}}}$

If :

A = area of trapezoid
a = bottom bases of trapezoid
b = top bases of trapezoid
h = height of trapezoid

Okay, let's we count its :

We know that :

a = bottom bases of trapezoid = 18 feet
b = top bases of trapezoid = 12 feet
h = height of trapezoid = 6 feet

Question : A = area = ... ?

Answer :

$A = \frac {(a+b) \times h}{2} \\ A = \frac {(12+18) \times \cancel6}{\cancel2} \\ A = 30 \times 3 = 90 \: {ft}^{2}$
