Answers

Answer 1

Answer:

The value of b = -2.7

Step-by-step explanation:

Given

As  the equation is given by

[tex]-5=b-2.3[/tex]

To determine

Solve the equation for b

Given the equation

[tex]-5=b-2.3[/tex]

switch the sides

[tex]b-2.3=-5[/tex]

Add 2.3 to both sides

[tex]b-2.3+2.3=-5+2.3[/tex]

Simplify

[tex]b=-2.7[/tex]

Therefore, the value of b = -2.7

Step-by-step explanation:

Because you simplify

f (x) = 2x² + 6x - 80

f (x) = 2x2+6x−80

f (x) = 2x2+6x−80

        = 2 (x−5)(x+8)

Sarah took out a $30,000 loan at a 4% interest rate to put a new pool in her backyard. If the interest is compounded quarterly, write a function to model this situation. How much interest will she have paid after 12 years?

Answers

Answer: $48,366.78

Step-by-step explanation:

3000(1+0.04/4) 4t

The function is A = 30,000(1+0.04/4)^(4t) and the compound interest is $18,366.78 if the interest is compounded quarterly.

What is compound interest?

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

Here P = $30,000

r = 4% = 0.04

n = 4

t = 12

The function of this situation:

[tex]\rm A = 30,000(1+\dfrac{0.04}{4})^{4t}[/tex]

Plug t = 12 in the above function.

[tex]\rm A = 30,000(1+\dfrac{0.04}{4})^{4\times12}[/tex]

A = $48,366.78

So compound interest CI = 48,366.78 - $30,000

CI = $18,366.78

Thus, the function is A = 30,000(1+0.04/4)^(4t) and the compound interest is $18,366.78 if the interest is compounded quarterly.

Answer:

Natalie's total spread = 18

Step-by-step explanation:

The 'spread' of a crossword puzzle tournament player is computed as his/her total score minus the opponent's total score.

Natalie's scores are:

N=410+380+395+370+320+360=2,235

Opponent's scores are:

O=395+360+412+355+340+355=2,217

Natalie's total spread = 2,235 - 2,217 = +18

Natalie's total spread = 18

Answer:

3) m∡ACB = 40 m∡ABC = 63

4) m∡BCA = 14 m∡ABC = 83

Step-by-step explanation:

Since DE is a line it has 180 degrees so:

103 + CAB = 180

CAB = 77 degrees

All triangle interior angles of a triangle add up to 180 degrees, so:

BAC + ACB + CBA = 180

3x - 14 + 3x + 9 + 77 = 180

6x + 72 = 180

6x = 108

x = 18

Plug in your values:

3(18) - 14 = 40

3(18) + 9 = 63

mr rolando sold the house and that at 10, 500,000.00 if he will receive 4% commansion, how much his commansion? ​

Answers

Given:

Mr. Rolando sold the house and that at 10,500,000.00.

Commission percent = 4%

To find:

The amount of commission.

Solution:

We have,

Commission percent = 4%

Commission = 4% of selling price of the house.

                     = [tex]\dfrac{4}{100}\times 10,500,000[/tex]

                     = [tex]4\times 105,000[/tex]

                     = [tex]420,000[/tex]

Therefore, the amount of commission is 420,000.

Step-by-step explanation:

use the distributive property

-2n + 24 + 1 = -2n + 25

-2n + 25 = -2n + 25

+2n            +2n      

25 = 25

infinite solutions

Answer:

infinitely many solutions

Step-by-step explanation:

-2(n-12)+1=-2n+25 Distribute.

-2n+24+1=-2n+25  Combine like terms on each side of the equation.

-2n+25=-2n+25      Add 2n on both sides of the equation.

+2n       +2n

25=25

This statement is true, so there are infinitely many solutions.
