Gnom [1K]3 years ago

The formula of the volume of a sphere is 4/3(πr^3). Radius is 1/2 the diameter so if the diameter is 18, the radius is 9. Now we plug that into the formula 4/3(π9^3). Now we solve for the volume step by step. First 9^3 = 729. Now 4/3(729π). Now divide 729 by 3 and multiply by 4 so 4(729/3) = 972π. The volume of the sphere is 972π.

What can you say about the end behavior of the function f(x)=-4^6+6x^2-52 ????
frosja888 [35]
Letter C is correct.
When the function is even, (all powers are even) both ends will go in the same direction.
In this case since the leading coefficient is negative, both ends will go down.

A game increased in price by 1/2 . After the increase it was priced at £27. What was the original price of the game? (Hegarty Ma
lukranit [14]

Answer:

£18

Step-by-step explanation:

Let

x = original price of the game

Increase in price = 1/2

New price = £27

x + 1/2x = £27

2x+x/2 = 27

3/2x = 27

x = 27 ÷ 3/2

= 27 × 2/3

= 54 / 3

x = £18

Therefore, the original price of the game is £18

When you divide a whole number by a fraction with a numerator of how can you find the quotient
UNO [17]
All you have to do is change the whole number to a fraction. Say you have 4 divided by 1/2. All you have to do to make a whole number a fraction is put it over 1. So now you would have 4/1 (4 being the numerator) divided by 1/2. When you divide fractions always remember this; Keep, Switch, Flip. Keep 4/1, Flip the division sign to multiplication, and Flip 1/2 to make it 2/1. Then you multiply the numerators and the denominators. So 4/1 * 2/1 = 8/1. Hope this helped.

Determine the payment to amortize the debt. (Round your answer to the nearest cent.) Quarterly payments on $19,500 at 3.9% for 6
Olin [163]

Answer:

$925.20

Step-by-step explanation:

Loan Amount, P = $19,500

Rate of interest, r = 3.9%

Time, t = 6 years

Payment mode, n = Quarterly (4)

payment to amortize, EMI = ?

Formula: EMI=\dfrac{P\cdot \frac{r}{n}}{1-(1+\frac{r}{n})^{-n\cdot t}}

where,

n = 4 , Rate of interest , r = 0.039

Put the values into formula

EMI=\dfrac{19500\cdot \frac{0.039}{4}}{1-(1+\frac{0.039}{4})^{-4\cdot 6}}

EMI=915.20

Hence, The payment to amortize the debt is $915.20
