Answer:

1.(f+g)(x)=5x-11

2.(f-g)(x)=x-3

Step-by-step explanation:

1.(f+g)(x)=f(x)+g(x)

=(3x-7)+(2x-4)

=5x-11

2.(f-g)(x)=f(x)-(g)

=(3x-7)-(2x-4)

=3x-7-2x+4

=x-3

Among all the rectangles whose perimeters are 100 feet, find the dimensions of the one with the maximum area. explain step by st

kompoz [17]

<span>We let x be the length and y be the width of the rectangle. Then,

Perimeter = 2x + 2y
100 = 2x + 2y
50 = x + y
y = 50 - x

Area = xy
A = x(50 - x)
A = 50x - x^2

We then take the derivative; set it equal to zero:

A ' = 50 - 2x
0 = 50 - 2x
2x = 50
x = 25
y = 50 - x
y = 50 - 25
y = 25

Therefore, the dimensions are 25 and 25.</span>

Suppose the radius of a circle is 3 units what is the circumference

HACTEHA [7]

Answer:

$6\pi$ or approximately $18.85$ units

Step-by-step explanation:

The formula for finding the circumference of a circle is $C=2\pi r$ , where $C$ = circumference and $r$ = radius. In this case, $r=3$ , so after plugging that into $C=2\pi r$ , we get:

$C=2\pi r\\ = 2*\pi *3\\=6\pi$

Since $\pi$ is approximately $3.1415$ , $6\pi =6*3.1415=18.849$ , which rounds to $18.85$ . Therefore, the circumference of the circle is $6\pi$ , or approximately $18.85$ units. Hope this helps!
