Answer:

<em>Surface Area: 10.24 square feet</em>

Step-by-step explanation:

In order to find the surface area, part the figure into 5 shapes; 1 being a square, the other 4 being equivalent triangles

Now find the area of the square, provided the dimensions 0.8 by 0.8:

A = 0.8 * 0.8 = 0.64 square feet

The area of the triangles are equivalent knowing that the share similar dimensions, 0.8 feet for the base and 6 feet for the height, so let us find the area of one at first:

A = 1/2 * 0.8 * 6 = 3 * 0.8 = 2.4 square feet

This means that the area of all 4 triangles are:

A = 2.4 * 4 = 9.6 square feet

The total surface area of this pyramid would then be the sum of the area of all 5 shapes, triangles and square:

Surface Area = 9.6 + 0.64 = 10.24 square feet

Can somebody help me with this?

Answer:

x=11

Step-by-step explanation:

Since this is a 90º angle, 46º+(4x)º has to equal 90º, and you can make and solve an equation for this:

46+4x=90

4x=44

x=11

Check:

46+4x=90

46+4(11)=90

46+44=90

90=90

Which two functions are inverses of each other?

liraira [26]

Answer:

Option 3 - f(x)= 4x, $g(x) = \frac{1}{4}x$

Step-by-step explanation:

To find : Which two functions are inverses of each other?

Solution :

Two functions are inverse if $f(g(x))=x=g(f(x))$

Now, we find one by one

1) f(x)= x, g(x) = -x

$f(g(x))=f(-x)=-x\neq x$

Not true.

2) f(x)= 2x, $g(x) = -\frac{1}{2}x$

$f(g(x))=f(-\frac{1}{2}x)=2\times(-\frac{1}{2}x)=-x\neq x$

Not true.

3) f(x)= 4x, $g(x) = \frac{1}{4}x$

$f(g(x))=f(\frac{1}{4}x)=4\times(\frac{1}{4}x)=x$

$g(f(x))=f(4x)=\frac{1}{4}\times 4x=x$

i.e. $f(g(x))=x=g(f(x))$ is true.

So, These two functions are inverse of each other.

4) f(x)= -8x, $g(x) =8x$

$f(g(x))=f(8x)=8\times(-8x)=-64x\neq x$

Not true.

Therefore, Option 3 is correct.
