Answer:

the second option is solution

Step-by-step explanation:

exponents inside parentheses get multiplied by exponents outside them

so first: x^-9y^6 divided by x^12y^18

next, when dividing like terms, keep variable and subtract their exponents

-9 - 12 = -21

6 - 18 = -12

Don't leave negative exponents as answer, simplify by putting them into the denominator (where the exponents will now become positive) with 1 as numerator

Answer:

A) The radius is 4 m

Step-by-step explanation:

Volume of cylinder formula:

V = πr²h

<h3>Given</h3>

V = 64π,
h = 4 m

Find r by substituting given values:

64π = πr²*4
64π = 4r²π
16 = r²
r = √16
r = 4 m

Correct choice is A.

A hovercraft takes off from a platform.

lubasha [3.4K]

Answer:

81 meters.

Step-by-step explanation:

The height (in meters), h(x) of a hovercraft x seconds after takeoff, is modeled by:

$h(x)=-3(x-3)^2+108$

We are to determine its height at the time of takeoff.

Now, at the time of takeoff, x=0.

We substitute x=0 to solve for h.

$h(0)=-3(0-3)^2+108\\=-3(-3)^2+108\\=-3(9)+108\\=-27+108\\=81$ meters$

The height of the hovercraft at takeoff is 81 meters.

Find the interest due on $600 at 9.5% for 120 days.

KATRIN_1 [288]

Answer:

Interest= $ 18.73

Step-by-step explanation:

Given : $600 at 9.5% for 120 days

To find : Find the interest due

Solution :

Simple interest formula $I=P\times r\times t$

Principle(P)=$600 , rate(r)=9.5%=0.095 , time (t)= 120 days

In years, 1 year = 365 days

1 day = $\frac{1}{365}$ year

120 days = $\frac{120}{365}$ year

Put values in the formula

$I=P\times r\times t$

$I=600\times 0.095\times\frac{120}{365}$

$I=\frac{6840}{365}=18.73$

Therefore, Interest= $ 18.73
