You invest $2000 in an account at 4.5% per year simple interest. How much will you have in the account at the beginning of the 8

77julia77 [94]

I will have $2721 at the beginning of the eighth year.

The beginning of the eighth year is the end of seven years of investing.

The formula for the future value (FV) of my investment is

FV = C(1 + r)^n

where C = my initial cash

r = the interest rate

n = the number of years

FV = $2000(1.045)^7 = $2722

The endpoints of the diameter of a circle are (-7.3) and (5.1). What is the center of the circle?

Minchanka [31]

Check the picture below.

since we know the endpoints of the diameter of the circle, then we can simply get the midpoint of those endpoints and that'd be the center,

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ (\stackrel{x_1}{-7}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{1}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{5-7}{2}~~,~~\cfrac{1+3}{2} \right)\implies \left( \cfrac{-2}{2}~~,~~\cfrac{4}{2} \right)\implies (-1~~,~~2)$

X Which of the following equations is correct?

Tanya [424]

Answer:

Option A is correct

Step-by-step explanation:

Given:

There are four option is given.

We need to find correct option.

Now we check the given option.

Option A.

$10^{5}\times 2.4 = 240,000$

Now we simplify the left side of the equation.

Simplify $10^{5} = 10\times 10\times 10\times 10\times 10 = 100,000$

And 2.4 replaced by $\frac{24}{10}$

$100,000\times \frac{24}{10} = 240,000$

$\frac{100,000\times 24}{10} = 240,000$

$\frac{2400000}{10} = 240,000$

$240,000 = 240,000$

So the value of left side of the equation is equal to the value of right side of the equation.

Therefore, option A is correct

THE VOLUME OF A CONE IS 15 PI CUBIC METERS. WHAT IS THE VOLUME OF A CYLINDER HAVING THE SAME BASE AND SAME HEIGHT?

Drupady [299]

Okay, so I know that you either multiply the volume of a cone by 3 to get the cylinders volume, or you divide it. I think you multiply it. Just remember, the rule is to multiply the volume of a cone by 3, to get the cylinder volume with the same measurements. So 15 x 3.
