Answer:

<h3>9x²-3x+1</h3>

Step-by-step explanation:

The rate of the change of the car is is its speed.

Speed = distance/time

Given

Distance = 27x³-9x²+3x

Time = 3x hours

Speed =  27x³-9x²+3x/3x

factor out 3x from the numerator:

Speed = 3x(9x²-3x+1)/3x

Speed = 9x²-3x+1

Hence the rate of the car is 9x²-3x+1

A<br> 19 = 548 and a<br> 33 = 968<br> Find a<br> 27
s2008m [1.1K]

Answer:

The value of a₂₇ is 788

Step-by-step explanation:

a₁₉ = 548

a₃₃ = 968

Now,

a₁₉ = 548 can be written as

a + 18d = 548 ...(1) and

a₃₃ = 968 can be written as

a + 32d = 968 ...(2)

Now, from equation (2) we get,

a + 32d = 968

a + 18d + 14d = 968

548 + 14d = 968 (.°. <u>a + 18d = 548</u>)

14d = 968 - 548

14d = 420

d = 420 ÷ 14

d = 30

Now, for the value of a put the value of d = 30 in equation (1)

a + 18d = 548

a + 18(30) = 548

a + 540 = 548

a = 548 - 540

a = 8

Now, For a₂₇

a₂₇ = a + 26d

a₂₇ = 8 + 26(30)

a₂₇ = 8 + 780

a₂₇ = 788

Thus, The value of a₂₇ is 788
