It can either reduce or add to its value. Say that you had a number 5. If you move the place it would make it .5 which reduced its value to not even 1. But with the same 5. if you move the place the other way to 50. It increases its value significantly.

Celine is 28, celines age is 4 more than 1/3 of drakes age. How old is drake?
ch4aika [34]

Answer:

Step-by-step explanation:

C = 28

C = 4 + 1/3 D

This means that

28 = 4 + 1/3 D

Subtract 4 from both sides.

24 = 1/3 D

Then to get rid of the fraction, multiply both sides by 3

72 = D

Therefore Drake is 72.

Verify that f and g are inverses functions using composition , show your steps
pshichka [43]

Answer:

See explanations below

Step-by-step explanation:

Given the functions

f(x) = 12x - 12

g(x) = x/12 - 1

To show they are inverses, we, must show that f(g(x)) = g(f(x))

f(g(x)) = f(x/12 - 1)

Replace x with x/12 - 1 into f(x)

f(g(x)) =12((x-12)/12) - 11

f(g(x)) =  x-1 - 1

f(g(x)) =x - 2

Similarly for g(f(x))

g(f(x)) = g(12x-12)

g(f(x)) =(12x-12)/12 - 1

12(x-1)/12 - 1

x-1 - 1

x - 2

Since f(g(x)) = g(f(x)) = x -2, hence they are inverses of each other

Find the perimeter of the figure
nalin [4]

Answer:

The perimeter is 66.9 units

Step-by-step explanation:

See the attached figure with letters to better understand the problem

step 1

In the right triangle ABD

<em>Find the length side AD</em>

tan(33^o)=\frac{8}{AD} ----> by TOA (opposite side divided by the adjacent side)

AD=\frac{8}{tan(33^o)}=12.3\ units

Find the length side BD

sin(33^o)=\frac{8}{BD} ---> by SOH (opposite side divided by the hypotenuse)

BD=\frac{8}{sin(33^o)}=14.7\ units

step 2

In the right triangle CDE

Find the length side CE

cos(64^o)=\frac{CD}{CE} --> by CAH (adjacent side divided by the hypotenuse)

we have

CD=BD/2=14.7/2=7.35\ units

substitute

CE=\frac{7.35}{cos(64^o)}=16.8\ units

Find the length side DE

tan(64^o)=\frac{DE}{CD} --> by TOA (opposite side divided by the adjacent side)

DE=tan(64^o){7.35}=15.1\ units

step 3

Find the perimeter of the figure

The perimeter is equal to

P=AB+AD+BD+CE+DE

substitute the values

P=8+12.3+14.7+16.8+15.1=66.9\ units
