Me asap and answer my other questions

Hello!

If all of the dimensions are multiplied by 3, the volume will also be multiplied by 3.

Our answer is A) 3.

I hope this helps!

We know the formula for volume of cylinder of given by

V = π r² h

If the dimensions are tripled, new volume will be :-

V' = π (3r)² (3h) = π (9r²) (3h) = 27 π r² h = 27 V

We can see new volume is 27 times original volume.

4x and 6y

im not sure though

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
