13. Find g(f(5)) if g(x) = 2x - 7 and F(x) = -4x - 7

Answers

Answer:

g(f(5)) = - 61

Step-by-step explanation:

Evaluate f(5) then substitute the value obtained into g(x) , that is

f(5) = - 4(5) - 7 = - 20 - 7 = - 27 , then

g(- 27) = 2(- 27) - 7 = - 54 - 7 = - 61

Given: AE = BD; CD = CE

Prove AC = BC

Answers

Step-by-step explanation:

Funny question!

AE=BD

A= BD/E

Then,

CD=CE

D=E

therefore, A=BE/E (SINCE, D=E)

So, A=B

or, AC= BC (multiplying by C)

The length of a rectangle is twice its width. The perimeter of the rectangle is 121 feet.
Plzzz help

Answers

Answer:

[tex]121=6w[/tex]

Step-by-step explanation:

Formula for perimeter of a rectangle:

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

[tex]w[/tex] = width

[tex]l[/tex] = length

Since the length is twice the width,

[tex]l=2w[/tex].

So, plugging these values into the formula, as well as the given perimeter of 121 feet, we get,

[tex]121 = 2(2w)+2w[/tex]

And after some simplification, we are left with,

[tex]121 = 6w[/tex]

Aggie is an australian exchange sudent in china, and she currenly has 14,000 yuan in her bank account. If the exchange rate changes from 1 australian dollar to 6.21 yuan to 1 australian dollar 6.37 chinese yuan, what happens to the value in australian dollars of the money in aggies bank account

Answers

Step-by-step explanation:

Amount in Aggie bank account = 14,000 yuan

Initial exchange rate:

1 Australian dollar = 6.21 yuan

Initial amount in Australian dollars will be;

x aus dollar = 14,000 yuan

cross multiply

6.21x = 14,000

x = 14,000/6.21

x =  2,254.428 australian dollars

If the exchange rate increases to 6.37 Chinese yuan, her new balance in Australian dollars will be y;

1 Australian dollar = 6.37 yuan

y Australian dollar = 14,000 yuan

cross multiply

6.37y = 14,000

x = 14,000/6.37

y = 2,197.80 Australian dollars

The change in her account balance due to increase in exchange rate is y-x

y-x = 2,197.80 - 2,254.428

y-x = -56.626 aus dollars

This negative values shows a decrease in her account balance by 56.626 aus dollars due to increase in the exchange rate.

Answers

Step-by-step explanation:

v=kg

36=k×4

k=36/4

k=9

9=v/11
Multiply both sides by 11 to get rid of /11

What is Greatest Common Factor?

In mathematics, the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

Given is to factor the given expression using the greatest common factor A = 48 + 80

For -

48 = 2 x 2 x 2 x 2 x 3

80 = 2 x 2 x 2 x 5

Using the greatest common factor, we can write -

48 + 80

8(6 + 10)

Therefore, the factored expression is equivalent to -

8(6 + 10)

Here, the largest number is

[tex]1.3 \times 10 ^3[/tex]

Next, is [tex]987[/tex]

Smaller than this, next is :-

for a fifth order polynomial, if x=a+bi is a root, and x=c+di is a root, how many real roots are there?
A. 1
B. 2
C. 5

Answers

1 roots are real.

If x=a+bi is a root then so is x=a-bi and if x=c+di is a root then so is x=c-di and all of those have imaginary numbers so they are not real therefore, there is only one real root.

A school nurse can give 25 eyes test in a two-hour period. How long will it atke the nurse to give eye test to all 600 student sin her school?

Answers

Answer:

96 hours

Step-by-step explanation:

25 eyes - 2 hours

1200 eyes* - x hours

[tex]x = \frac{2 \times 1200}{25} [/tex]

[tex]x = 96[/tex]

*each student has 2 eyes. So 600 students have 600×2=1200 eyes.

It will take the nurse 48 hours to give eye tests to all 600 students in her school.

What is Expression?

An expression is combination of variables, numbers and operators.

If the nurse can give 25 eye tests in two hours, then she can give 12.5 tests in one hour (since 25 divided by 2 equals 12.5).

To give eye tests to all 600 students, the nurse will need to give 600 tests in total.

Using the rate of 12.5 tests per hour, we can set up a proportion:

12.5 tests / 1 hour = 600 tests / x hours

Apply Cross-multiplication

12.5 tests ×  x hours = 600 tests

Divide both sides by 12.5 tests

we get,  x hours = 600 tests / 12.5 tests per hour

x hours = 48 hours

Therefore, it will take the nurse 48 hours to give eye tests to all 600 students in her school.
