PLEASE hurry brainiliest Suppose that a piano costs $5,000 and loses 20% of its value each year. The table below shows the value, v, of a piano after, t, years.

Number of Years Since Purchase (t)

Value of Piano (v)

0# of years since purchase

$5,000 value of piano

1

$4,000

2

$3,200
Complete the missing values in the table.
3 years and 4 years
Question 4 Part B: Write an equation to find the value of the piano, v, after t years.
Question 4: Part C: What will be the value of the piano after 16 years? Round your answer to the nearest hundredth.

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

ratio is 2 : 9

the answer is three

13.5 : 3

the answer is 13 cm
