Answer: $SA=117.2\ in^2$

Step-by-step explanation:

You need to remember the following:

1. The area of a rectangle can be calculated with the following formula:

$A_r=lw$

Where "l" is the length and "w" is the width.

2. The area of a triangle can be calculated with the following formula:

$A_t=\frac{bh}{2}$

Where "b" is the base and "h" is the height.

Use those formulas to find the area of each face.

Area of the rectangle

$A_r=(10\ in)(4\ in)=40\ in^2$

Area of two triangles

There are two equal triangles. Each one has a base of 10 inches and a height of 5 inches. Then, their areas are equal:

$A_{t1}=A_{t2}=\frac{(10\ in)(5\ in)}{2}=25\ in^2$

The areas of the other two triangles (which are equal) are:

$A_{t3}=A_{t4}=13.6\ in^2$

Adding the areas of the faces, you get that the surface area of the rectangular pyramid is:

$SA=40\ in^2+25\ in^2+25\ in^2+13.6\ in^2+13.6\ in^2\\\\SA=117.2\ in^2$

H=vt+1/2gt^2 solving for G GIVING BRAINLISEST

ololo11 [35]

Answer:

$g=\frac{2h}{t^2}-\frac{2v}{t}$

Step-by-step explanation:

So we have the equation:

$h=vt+\frac{1}{2}gt^2$

And we want to solve for g.

First, isolate g. To do so, subtract vt from both sides:

$h-vt=\frac{1}{2}gt^2$

Multiply both sides by 2:

$2h-2vt=gt^2$

Now, divide both sides by t^2:

$g=\frac{2h-2vt}{t^2}$

Expand:

$g=\frac{2h}{t^2}-\frac{2vt}{t^2}$

Simplify the second term:

$g=\frac{2h}{t^2}-\frac{2v}{t}$

And we're done!
