Answer:

12.6

Step-by-step explanation:

a. 315 - 25 = $290

b. After each payment, the amount owed decreases. Therefore, the balance decreases.  

second part of this: write equation for calculating the amount owed a for any number of payments n                      $      $25(n-1)  =a

I cant draw a graph on here for you, but as n increases, then a decreases

d. as n increases by 1, how does a change?  Answer: A decreases by $25 each time n increases by one

e. He will need to make 12.6 payments

In ΔQRS, the measure of ∠S=90°, the measure of ∠R=29°, and SQ = 5.8 feet. Find the length of RS to the nearest tenth of a foot.
taurus [48]

Answer:

10.5 ft

Step-by-step explanation:

In ΔQRS,

  • m∠S=90°
  • m∠R=29°,
  • SQ = 5.8 feet.

See the diagram below.

The triangle is a Right Triangle,

Using trigonometric ratios,

Tan R=\dfrac{|SQ|}{|RS|} \\Tan 29^\circ=\dfrac{5.8}{|RS|}\\$Cross multiply$\\|RS|XTan 29^\circ=5.8\\|RS|=\dfrac{5.8}{Tan 29^\circ}\\$=10.5 ft (to the nearest tenth of a foot)

Solve by completing the square.
enot [183]

Answer:

x^2 -8x -5 = -3

x^2 -8x -2 = 0

We complete the square by:

1) Moving the "non X" term to the right:

x^2 -8x  = 2

2) Dividing the equation by the coefficient of X²

The coefficient of x is 1 so we don't do anything

3) Now here's the "completing the square" stage in which we:

      • take the coefficient of X

that is -8

     • divide it by 2

-8 ÷ 2 = -4

     • square that number

-4*-4 = 16

     • then add it to both sides of the  equation.

x^2 -8x +16 = 2 +16

That becomes

(x -4)^2 = 18

we take the square root of both sides:

(x -4) = sqr root (18)

x1 = sqr root (18) +4

AND

(x+4) = sqr root (18) -4

x1 =  sqr root (18) +4 = 4.2426406871  + 4 = 8.2426406871

x2 = sqr root (18) -4 =  = 4.2426406871  - 4 = .2426406871

In your notebook, set up the following subtraction in a vertical format and select the correct answer.
prohojiy [21]

Answer:

4p^{2} +6p-8

Step-by-step explanation:

Remember these rules for addition, substraction, multiplication or division:

Addition

+ + = +

- - = -

Big + number - =  +

Big -number + =  -

Substraction

change the sign!

And follow the rules for addition

Multiplication or division

+ + = +

- - = +

+ - = -

Now for the exercise

2p^{2} + 3p - 4

<u>- (- 2p^{2} -3p +4)</u>

<u />

Change the signal

2p^{2} + 3p - 4

<u>(+2p^{2}+3p-4)</u>

4p^{2} + 6p -8
