F(x)=3x and g(x)=x+2 find fog(x),gof(x),fog(2),gof(2)

Answers

Answer 1

Answer:

Step-by-step explanation:

fog(x)=f(g(x)) =f(x+2) =3⋅(x+2) =3x+6

gof(x)=g(f(x))=g(3x) =3x+2

gof(2)=3⋅2+2 =6+2 =8

fog(2)=3⋅(2+2) =3*2+6=12

The side lengths of a rectangle are all multiplied by 5. What happens to its perimeter?

Answers

Answer:

The perimeter is multiplied by 5.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle with sides l and w is given by:

[tex]P = 2(l + w)[/tex]

The side lengths of a rectangle are all multiplied by 5.

This means that [tex]l = 5l, w = 5w[/tex]. So

[tex]P_M = 2(5l + 5w) = 2*5(l+w) = 10(l + w)[/tex]

What happens to its perimeter?

The rate is:

[tex]\frac{P_M}{P} = \frac{10(l+w)}{2(l+w)} = 5[/tex]

The perimeter is multiplied by 5.

What is the perimeter of the track, in meters? Use tt 3.16 and round to the nearest hundredth of a meter

Answers

Answer:

The perimeter of the track is of 317 meters.

Step-by-step explanation:

Perimeter:

The perimeter of a figure is the sum of all its dimensions.

In this question:

The track is composed by two straights of 80m, and two half circles with a diameter of 50m.

Perimeter of a circle:

The perimeter of a circle with diameter d is of:

[tex]P = \pi d[/tex]

Track:

Two half circles, each with a diameter of 50m, plus two straight lines of 80m. So

[tex]P = \frac{2\pi}{2}(50) + 2*80) = 50\pi + 160 = 50*3.14 + 160 = 317[/tex]

The perimeter of the track is of 317 meters.

A gift box has the dimensions shown below. 16 in x11 in. What is the perimeter of the box in feet

A. 4 feet 1/2 inch
B. 4 feet 6 inches
C. 54 inches
D. 4 feet

Answers

The formula for perimeter is 2l+ 2w so 2(16)+ 2(11)= 54 and since there are 12 inches in 1 ft, you have to divide 54 by 12 to get 4.5 feet (or 4 feet 6 inches)
So, you answer is B

Pls answer its khan academy I really need it

Answers

Answer:

Step-by-step explanation:

Note the f(0) = 9

and f(1) = 15

Since, f(x) = abˣ substituting for x, we get:

9 = f(0) = a . b⁰ = a

⇒ a = 9

Now, f(1) = 15

⇒ 15 = a . b¹

⇒ 15 = 9 . b

⇒ b = 15/19

Therefore,

f (r) = 9. (5/3)

Hence, the answer.
