Suppose your​ friend's parents invest 15,000 in an account paying 7% compounded annually. What will the balance be after 5 ​year
meriva

Answer:

FV= $21,038.28

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $15,000

Interest rate (i)= 7% compounded annually

Number of periods (n)= 5

<u>To calculate the future value (FV), we need to use the following formula:</u>

FV= PV*(1 + i)^n

FV= 15,000*(1.07^5)

FV= $21,038.28

A fruit company delivers its fruit in two types of boxes: large and small. a delivery of 5 large boxes and 3 small boxes has a t
Hoochie [10]
Let's let the weight of a large box be L, and the weight of a small box be S.

We know that 5 large boxes and 3 small boxes is 120kg, so:
5L + 3S = 120

We also know that 7 large boxes and 9 small boxes is 234kg, so:
7L + 9S = 234

You can multiply the first equation by 3 to get:
15L + 9S = 360

See how now both equations have 9S? We can now subtract one from the other:
(15L+9S) - (7L+9S) = 360-234
8L = 126
L = 15.75

Now sub this value back into an equation:
(5x15.75) + 3S = 120
3S = 41.25
S = 13.75

Double check these values
(7x15.75) + (9x13.75)
= 110.25 + 123.75
=234, which is consistent with above.

So a large box is 15.75kg, and a small box is 13.75kg.

Hope this helped

I can't fail and no one has answered my previous questions so please help.
Afina-wow [57]
When you know your equation f(x) and they want you to find f(-4), it means that they want to know what f(x) is worth when x=-4 Therefore, you only need to plug in you x in the equation f(x)=5x-2 f(-4)=5(-4)-2 =-20-2 =-22 (B)

Determine whether abc ----&gt; jgh is a reflection, translation, rotation, or glide reflection.
Usimov [2.4K]
From this picture you can calculate coordinates of triangles' vertices:
A(-9,0),\ B(-6,-4),\ C(-3,0),\ J(8,0),\ G(5,4),\ H(2,0).

Since 

\frac{-9+8}{2} = \frac{-6+5}{2}= \frac{-3+2}{2}=- \frac{1}{2} \frac{0+0}{2}= \frac{-4+4}{2} = \frac{0+0}{2} =0 

you can conclude that points A, B, C are rotated by 180^0 about the point (-0.5,0) to form points J, G, H, respectively.

Answer: A is correct choice.
