If the present value of a growing perpetuity is 214, the required rate of return is 10%, and growth rate is 3%, what is the cash
Kryger [21]

The cash flow in year 1 is $15.

<h3>What is the cash flow in year 1?

A growing perpetuity increases continuously and indefinitely.

Cash flow = present value x (rate of return - growth rate)

214 x (10% - 3%)

214 x 0.07 = $15

Find m angle ABC <br> I really need the answer to this
damaskus [11]
To find <ABC, the first thing you would need to do is to find angle DBA and the value of x

As <DBE is a right angle, <DBE is on the same straight line as well,meaning that it would be 90° , a right angle as well.

It also mean that the total sum of the angles unknown would be 90°

To find x,we need to set up an equation:
(2x+14)+ (x+7) = 90
3x+21 = 90
3x = 69
x = 23

Thus,<ABC would be
(23)+7
=30°

Hope it helps!

Eliminating by multiplying <br> X+3y=1<br> -5x+4y=-24
gavmur [86]

Answer:

y = -1         x = 4

Step-by-step explanation:

(X+3y=1) 5            Multiply this equation by 5 to cancel out the x

-5x+4y=-24

-5x + 4y= -24

+ 5x + 15y = 5       Add both equations together

19y = -19                Divide both sides by 19

y = -1

Plug -1 for y into one of the equations

x + 3(-1) = 1             Multiply 3(-1)

x - 3 = 1

 + 3 + 3                  Add 3 to both sides

x = 4

A cylinder with a 2 centimeter diameter is drilled through the triangular prism shown on the left find the volume of the prism
saw5 [17]

Answer:

The volume of a prism on its own = 248.5cm^3

The volume of a cylinder  = 87.92cm^3

Step-by-step explanation:

The volume does not change for the prism as the hole was drilled.

We can show the drilled space with v(l) and (p) for prism V

v(l) 248.5p - 87.92p + 87.92p

= 248.5p
