Answer:

a(y=-5x+2500) b(2,380) c(25months)

Step-by-step explanation:

someone point out if I'm wrong. I'm not so sure about "c".

(how I got b)

So 2 years=24 months

y=-5x+2500

So x would be 24.

-5(24)+2500

-120+2500

2,380

allochka39001 [22]

3 {(4 + x)}^{2}  - 10(x + 4) + 2 - 5
so
3( {x}^{2}  + 8x + 16) - 10x - 40 + 3
so
3 {x}^{2}  + 14x + 11
take differential calculus
6x + 14 = 0
you will find x then y

Lamont retired at age 55 and rolls over $300500
Arlecino [84]

If Lamont withdraws $2,750 monthly, he will be <u>66 years old</u> (after 134.326 months) when the money runs out.

<h3>How is the number of monthly withdrawals calculated?</h3>

We can calculate the number of monthly withdrawals using an online finance calculator.

It determines the number of periods it will take for the investment to be exhausted, given an interest rate of 3.8%.

I/Y (Interest per year) = 3.8%

PV (Present Value) = $300,500

PMT (Periodic Payment) = $-2750

FV (Future Value) = $0

<u>Results</u>:

N = 134.326 months

Years = 11 years (134.326/12)

Age at FV = $0 is 66 years (55 + 11)

Sum of all periodic payments = $-369,397.09 (134.326 x $-2,750)

Total Interest = $68,897.09

Thus, making a monthly withdrawal of $2,750 will exhaust the investment when Lamont turns <u>66</u>.

If r and s are positive integers, each greater than 1, and if 11(s-1) =13(r-1), what is the least possible value of (r+s)?
Tresset [83]

Answer:

The least value of (r+s) is (12+14)=26

Step-by-step explanation:

Well, first let us solve equation of 11(s-1)=13(r-1), which results in 11s-11=13r-13. Hence, 11s+2=13r. It is stated that r and s both are integers and greater than 1.

To make sure that r and s are integers, the least value of s must be equal to 14 (s=14) then the least value of r becomes 12 (r=12).

Finally, the least value of (r+s) is (12+14)=26.

Remember to identify the length, width,
Amiraneli [1.4K]

Answer:

If the prism is trapezoid then you need to find the height and use this formula

1/2 x a+b x h

This has been done below you only need to fill in the height and do the shape for 3cm x 2cm as you haven't been clear in your question.

Volume = 8 x h x 10 = 80 x h cm^3

Hope this helps.

Step-by-step explanation:

Slope triangle prism and or rectangle

The area can be seen either by finding height of the triangle or working out the rectangle and halving the rectangle.

Step-by-step explanation:

Volume

6 x 8 = 48cm^2

48 x 5 = 230cm^2 for double (rectangle prism of 6 x8)

385/2 = 115cm^2 triangle slope prism

---------------

Area first

trapezoid front measures 6,5, 10

1/2 x 6 + 5 x h

=1/2 x 6 + 5 x h

= 8 x h x 10= 80 x h

Volume = 8 x h x 10 = 80 x h cm^3
