A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find
Pachacha [2.7K]

Answer:

f(x)=120,000 \times (1.055)^{x}.

Step-by-step explanation:

We are given that,

The present value for the home is $120,000 and the rate of interest is 5.5% i.e. 0.055.

As we know that the function for the home is given by,

f(x)=P \times (1+r)^{x}

where P = present value, r = rate of interest, x = number of years.

So, according to the question, we get that,

f(x)=120,000 \times (1+0.055)^{x}

i.e. f(x)=120,000 \times (1.055)^{x}.

Hence, we see that the function that represents the value of the home is f(x)=120,000 \times (1.055)^{x}.

A rectangle has an area of 36 inches squared. Write an equation to show how the length (l) varies inversely the width (w).
Anastaziya [24]
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36

Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.

Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x

You’re piloting an airplane to prepare for landing you change the planes altitude from a meters to c meters.
soldier1979 [14.2K]

Answer:

|a-c| meters

Step-by-step explanation:

If I am piloting an airplane to prepare for landing, I change the plane's altitude from a meters to c meters, then the expression that represents the distance between two altitudes is given by |a-c| meters, not by |a+c|.

For, example if the altitude of the plane changes from 1000 meters to 500 meters for preparing for landing then the distance between those two altitudes is |1000 - 500| = 500 meters. (Answer)

But using the expression |a+c|, I will get the wrong answer as |1000 + 500| = 1500 meters.
