Find v(w+3) for v(w)=2w-1

Mathematics

sergey [27]4 years ago

So we have v(w) = 2w - 1

Now we make the following change: w ---> w +3.
So we change every "w" into a "w+3" as follows:

v(w) = 2w - 1 --------> v(w+3) = 2*(w+3) - 1

Let's solve this.
2*(w+3) - 1
2*w + 2*3 - 1
2w + 6 - 1
2w + 5

So

v(w+3) = 2w + 5

Adam buys a car for £18680 which depreciates in value at a rate of 2.5% per year. Work out how much Adam's car will be worth in
timofeeve [1]

Answer:

Adam's car will be 8,406£ in 22 years.

Step-by-step explanation:

I. Find the lose value of 2.5% car by

2.5/100 = x/18,680

46,700/100 = x

x = 467 or the lose value in 1st year.

II. Find the true value of Adam's car by

n year = 18,680 - 467(n)

1st = 18,680 - 467(1)

    = 18,213 means if he sell his car now, he'll get 18,213£

22th = 18,680 - 467(22)

        = 18,680 - 10,274

        = 8,406£

That makes 8,406£ is the right answer.

Hope that help :)

The expression 8x2 − 64x + 720 is used to approximate a small town's population in thousands from 1998 to 2018, where x represen
mezya [45]

Answer:

8(x-4)^{2}+592

Step-by-step explanation:

we have

The expression  8x^{2} -64x+720

This is a vertical parabola open upward

The vertex is a minimum

Convert the expression in vertex form

Factor the leading coefficient

8(x^{2} -8x)+720

Complete the square

8(x^{2} -8x+16)+720-128

8(x^{2} -8x+16)+592

Rewrite as perfect squares

8(x-4)^{2}+592

The vertex is the point (4,592)

That means -----> 4 years since 1998 the population has a minimum
