A person invested $7,400 in an account growing at a rate allowing the money to
double every 6 years. How much money would be in the account after 4 years, to the
nearest dollar?

Answers

Answer 1

Using an exponential function, it is found that $11,747 will be in the account after 4 years.

What is an exponential function?

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

A(0) is the initial value.r is the growth rate, as a decimal.

In this problem, considering the initial investment of $7,400, and the fact that it doubles every 6 years, the equation is given by:

[tex]A(t) = 7400(2)^{\frac{t}{6}}[/tex]

Hence the amount in 4 years is given by:

[tex]A(4) = 7400(2)^{\frac{4}{6}} = 11747[/tex]

The NYC subway system has a total of 850 miles of train tracks, and a NYC subway train has an average speed of 17.4 mph. If you laid all 850 miles of track end-to-end in one big circle, how much time would it take to ride a NYC subway train around the entire circumference of that circle?

Answers

Answer:48.85 hr

Step-by-step explanation:

Given

The length of the train track is [tex]L=850\ miles[/tex]

the average speed of the train is [tex]v_{avg}=850\ mph[/tex]

If this track is laid on to a big circle, then the length is equivalent to the circumference

time is taken to cover the circumference is given by

[tex]\Rightarrow t=\dfrac{L}{v}\\\\\Rightarrow t=\dfrac{850}{17.4}=48.85\ hr[/tex]

What type of function is this: y=.7X ?

1:Quadratic

Answers

Answer:

Linear (4)

Step-by-step explanation:

I assume that by " y=.7X " you actually meant " y = 7x"

If that's the case, this y=7X is a LINEAR function.  Its graph is a straight line.

If you meant " y = 0.7x " that is still a LINEAR function whose slope is smaller than that of y = 7x.

So, lets think about how many inches are in a foot. If you dont know, think about how many inches are on a ruler, 12 right? Well, thats how many inches are in a foot.

So knowing that the truck is 162 inches, lets find how many inches the bridge is. We can do this by multiplying the feet, which is 12. 12(feet) times 12(inches in a foot) equals 144.

Remember that the problem said 12 feet and 5 inches, so we know 12 feet is 144 inches, now we jsut need to add the 5 inches. Well, 144 plus 5 is 149. Clearly, 162(truck) is greater than 149(bridge).

How much taller? lets subtract the heigh of the truck by the bridge: 162-149.

This should get you 13.

So the answer must be that the truck is 13 inches taller.
