You find 1 and 2 on the x-axis and put a dot in the middle of those two numbers. Then, find -2 on the y-axis and put a dot there. And then connect the dots.

What is the present value of a fund that earns 15% on its balance each year, from which $10,000 must be paid a year for 6 years,
Masteriza [31]

Answer:

The present value of the fund=$25,939.66

Step-by-step explanation:

Step 1

Determine the future value of the fund as shown;

Future value(F.V)=payment amounts per year×number of years

where;

payment amounts per year=$10,000

number of years=6

replacing;

Future value (F.V)=(10,000×6)=60,000

Future value (F.V)=$60,000

Step 2

Determine the present value (P.V) of the fund as shown;

F.V=P.V(1+r)^n

where;

F.V=future value

P.V=present value

r=annual interest rate

n=number of years

In our case;

F.V=$60,000

P.V=unknown

r=15%=15/100=0.15

n=6

replacing;

60,000=P.V(1+0.15)^6

60,000=P.V(1.15)^6

P.V=60,000/{(1.15)^6}

P.V=25,939.66

The present value of the fund=$25,939.66

-3 - 8 = 19<br> —3x - 2 = 25
Delicious77 [7]

Answer:

a negative times a negative is a positive so 8×3=24/19 will give you that answer

you add -2 to the other side with 25 and get 27 then u work the rest of the problem out to solve for x

Answer:

52.9 inches .

Step-by-step explanation:

Given that the triangular indentation has an area of 100 in.² and the base and height of this traingle are represented by expressions 3x and x+3 respectively . We need to find out the <u>perimeter </u>to the nearest tenth.

As we know that the area of triangle is ,

\rm\longrightarrow Area_{\triangle}=\dfrac{1}{2}(base)(height)

Substituting the respective values,

\rm\longrightarrow 100\ =\dfrac{1}{2}(x+3)(3x)\\\\\rm\longrightarrow 2(100) = 3x(x+3)\\\\\rm\longrightarrow200 = 3x^2+9x\\\\\rm\longrightarrow 3x^2+9x-200=0

On using the <u>Quadratic</u><u> formula</u> , we have;

\rm\longrightarrow x =\dfrac{-9\pm\sqrt{9^2-4(3)(-200)}}{2(3)} \\\\\rm\longrightarrow x =\dfrac{-9\pm \sqrt{81+1200}}{6}\\\\\rm\longrightarrow x =\dfrac{-9\pm \sqrt{1281}}{6}

On simplifying above , we will get ,

\rm\longrightarrow x = 6.802,-9.802

Since sides can't be negative, therefore,

\rm\longrightarrow\underline{\underline{ x =6.802}}

Therefore ,

  • \rm\longrightarrow Base = 3x =3(6.802)in = 20.406\ in\\
  • \rm\longrightarrow Height = x +3=6.802+3=9.802\ in

Next let's find out the <u>hypotenuse </u>using Pythagoras theorem, as ;

\rm\longrightarrow h=\sqrt{ b^2+p^2}\\

\rm\longrightarrow h =\sqrt{ (20.406)^2+(9.802)^2}\\

\rm\longrightarrow h =\sqrt{416.40+96.07}\\

\rm\longrightarrow h = 22.63\ in

Now we may find perimeter as ,

\rm\longrightarrow P = p + b + h \\

\rm\longrightarrow P = (22.63 + 9.802 + 20.406)in.

\\\rm\longrightarrow P = 52.89 \ in.\\

\rm\longrightarrow \underline{\underline{ Perimeter = 52.9\ in .}}

There are only blue ,yellow cubes and green cubes in a bag there are 5 times as many blue cubes as yellow cubes and there are 5
Molodets [167]

Answer:

1 / 31

Step-by-step explanation:

Given that:

Yellow (y) ; Blue (b) ; Green (g)

b = 5y

g = 5b

Assume :

Number of yellow cube = 1

y = 1

b = 5

g = 5*5 = 25

Probability = (required outcome / number of total possible outcomes)

P( picking a yellow) = number of yellow / total number of cubes

Total number of balls = (1 + 5 + 25) = 31

P(picking a yellow) = 1 / 31
