First off,we need to understnad the formula of a cone:
\frac{1}{3} \pi \times {radius}^{2} \times height
In this case,the radius:
=5.8÷2
=2.9in

The volume of the cone:
\frac{1}{3} \pi \times {2.9}^{2} \times 16 \\ = \frac{1}{3} \pi \times 134.56 \\ = \frac{3346}{75} \pi \\ = 140.9109...

Therefore,the answer is 3365/75兀 or 140.91.

Hope it helps!

According to the Complex Conjugate Root Theorem, if a+bi is a root of a quadratic equation, then __blank__ is also a root of the
Trava [24]

Answer:

a-bi


Step-by-step explanation:

If a quadratic equation lx^2+mx+n=0 has one imaginary root as a+bi then the other root is the conjugate of a+bi = a-bi

Because we have l, m and n are real numbers and they are the coefficients.

Sum of roots = a+bi + second root = -m/l

When -m/l is real because the ratio of two real numbers, left side also has to be real.

Since bi is one imaginary term already there other root should have -bi in it so that the sum becomes real.

i.e. other root will be of the form c-bi for some real c.

Now product of roots = (a+bi)(c-bi) = n/l

Since right side is real, left side also must be real.

i.e.imaginary part =0

bi(a-c) =0

Or a =c

i.e. other root c-bi = a-bi

Hence proved.

Look at 3 on Variable B's axis, then go to the right until you reach the line.

After you reach the line, go all the way down and see what number you get to on Variable A's axis. You get 8, so that is your answer.

Can someone please help me-
puteri [66]

Answer:

can be expressed as decimal: 0.025

s= 1.025* $250

 = $256.25

after 8 years

s= $250* 1.025^8

 ~$304.6

earned $54.6

Step-by-step explanation:

2 and a half is equivilant to 2.5

because it is a % (out of 100) move the decimal 2 places down

2.5-->0.25-->0.025

so can be expressed as decimal: 0.025

interest after 1 year is:

original amount of money * (interest rate+1.0)

+1 because you are adding on to 100%. you already have 100%.  if it was just the interest rate, the amount of money would go down.

so

s= 1.025* $250

=1.025* 250

=256.25

interest after 8 years,

that means you have to take the original, and multiply it by the interest rate, then the new original multiply by intrest rate a total of 8 times

to do this use an exponent, because exponents base the total off the total before them. if that makes any sense srry

s= $250* 1.025^8

 ~$304.6  (I used calculator)

to get her earnings, subtract the new amount of money with her original amount of money

304.6-250

=54.6

$54.6

hope this helps
