First, think about what you know.

The problem is giving you feet for both of the numbers, which is good for you on your part considering you have no measurements to convert.

You also know that you have 5 feet of space in your house to possibly hold a piano. If a piano is larger than five feet, you won't have enough room.

You also know that you can find out if a number is bigger by getting the number out of improper fraction form.

So, to solve this problem, remove the improper fraction. Change 19/4 into 4 3/4, instead. If unsure how to get out of improper fraction format, simply see how many times you can get four into 19. That would be your whole number. Then, let the left over number go over your original denominator. 

Four goes into nineteen 4 times. 4 x 4 is 16 and the leftover amount until 19 would be 3. ( 19 - 16 ) So, place 3/4 and you have 4 and 3/4.

- you could also turn into a decimal to solve instead -

Now, you realize that the piano is 4 3/4 ft long and you have 5 feet of space. The piano is smaller than your house space, and therefore, Ali does have enough room.

The radius of a circular pond is increasing at a constant rate, which can be modeled by the function , where t is time in months
horrorfan [7]

Answer:

B. A(r(t)) = 25πt²

Step-by-step explanation:

Find the completed question below

The radius of a circular pond is increasing at a constant rate, which can be modeled by the function r(t) = 5t where t is time in months. The area of the pond is modeled by the function A(r) = πr². The area of the pond with respect to time can be modeled by the composition . Which function represents the area with respect to time? A. B. C. D.

Given

A(t) = πr²

r(t) = 5t

We are to evaluate the composite expression A(r(t))

A(r(t)) = A(5t)

To get A(5t), we will replace r in A(t) with 5t and simplify as shown

A(5t) = π(5t)²

A(5t) = π(25t²)

A(5t) = 25πt²

A(r(t)) = 25πt²

Hence the composite expression A(r(t)) is 25πt²

Option B is correct.

Bobby's investment of $225,000 loses value at a rate of 3% per year. Use an exponential function to find the value of the invest
AleksAgata [21]

We have been given that Bobby's investment of $225,000 loses value at a rate of 3% per year. We are asked to find the value of the investment after 10 years.

We will us exponential decay function to solve our given problem.

We know that an exponential function is in form y=a\cdot (1-r)^x, where,

y = Final amount,

a = Initial amount,

r = Decay rate in decimal form,

x = Time.

Let us convert 3% into decimal.

3\%=\frac{3}{100}=0.03

Upon substituting a=\$225,000, r=0.03 and x=10, we will get:

y=\$225,000(1-0.03)^{10}

y=\$225,000(0.97)^{10}

y=\$225,000(0.7374241268949283)

y=\$165,920.4285513588675

Upon rounding to nearest dollar, we will get;

y\approx \$165,920

Therefore, the value of the investment after 10 years would be \$165,920.
