The amount that was invested 17 years ago is $2064.25.
The interest earned is $7935.75.
What is the amount invested 17 years ago?The formula that would used to determine the amount that was invested 17 years ago is:
P = FV / (1 + r)^nm
Where:
FV = Future value = 10,000P = Present value R = interest rate = 9.5 / 2 = 4.75%m = number of compounding = 2 N = number of years = 1710,000 / (1.0475)^(17 x 2) = $2064.25
Interest earned = 10,000 - 2064.25 = $7935.75

Three solid shapes a, b and c are similar.
the volume of shape a is 27 cm
the volume of shape b is 64 cm
the ratio of the surface area of shape b to the surface area of shape c is 8:15
work out the ratio of the height of shape a to the height of shape c.
The ratio of the height of shape A to the height of shape C is [tex]\frac{3}{10}[/tex]
Calculations and Parameters:First step:Recall that similar figures have the same scale factor squared due to the ratio of its surface area.
Hence,
We would make:
z-----> the scale factorx----> surface area shape Ay----> surface area shape B[tex]z^2 = x/y\\z= 2/5[/tex]
Therefore, the ratio of the height of shape A to the height of shape B is = [tex]\frac{hA}{hB} = \frac{2}{5}[/tex]
Next step:To find the ratio of the height of shape B to the height of shape C, we would perform a similar operation which is:
[tex]z^3 = 27/64\\z= 3/4[/tex]
The ratio is:
[tex]\frac{hB}{hC} = \frac{3}{4}[/tex]
Final step:To find the ratio of the height of shape A to the height of shape C would be:
[tex](\frac{hA}{hB}) (\frac{hB}{hC} )= \frac{hA}{hC}[/tex]

Write an exponential equation for the graph shown
below.
Explain how you determined the equation.
The exponential equation of the graph is y = 1.59 * 1.26^x
How to determine the exponential equation?On the graph, we have the following points
(x,y) = (2,1) and (4,4)
An exponential function is represented as;
y = ab^x
So, we have:
ab^1 = 2 and ab^4 = 4
Divide both equations
b^3 = 2
Take the cube root of both sides
b = 1.26
Substitute b = 1.26 in ab^1 = 2
1.26a = 2
Divide both sides by 1.26
a = 1.59
So, we have:
y = ab^x
y = 1.59 * 1.26^x
Hence, the exponential equation of the graph is y = 1.59 * 1.26^x

Reset
Answer:Calvin throws 12 sheets of paper up in the air.
He randomly catches one of the sheets as they float down.
Of the 12 sheets of paper, 9 are white and 3 are red.
Probability = Number of favorable outcomes/ total number of outcomes
The probability that Calvin caught a white sheet is = or 75%.
It is likely that this event occurs as above 70% we say that the event is likely and here the probability is 75%.
The probability that Calvin caught a red sheet is = or 25%
This is unlikely to happen. Thus, we can say that it is not likely event.

The expression of time in terms of r is T = 85/9r. If he walked at an average speed of 3 miles per hour. Then the time taken by nick to reach the shopping mall will be 3 hours and 60 minutes.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
Nick walked 5 miles to reach his aunt's house.
From there he traveled 8 miles to the shopping mall on a bicycle.
He traveled 80% faster on the bicycle than on foot.
Let r represent his rate of walking in miles per hour. Then the 1.8r will be the rate of cycling in miles per hour.
Then the number of hours nick took to reach the shopping mall in terms of r will be
T = t₁ + t₂
Where t₁ is the time taken to reach his aunt's house and t₂ is the time taken to reach the shopping mall from his aunt's house. Then we have
T = 5 / r + 8 / 1.8r
T = 1/r (5 + 8/1.8)
T = 85/9r
If r is 3 miles per hour, then the time taken by nick to reach the shopping mall will be
T = 85 / (9 x 3)
T = 3.15 hours
T = 3 hours and 9 minutes

$75 before tax. Disc: 10% Tax: 7%, Tip: 20% what’s the total?
Answer:
$102.75
Step-by-step explanation:
Given the following question:
We are given a cost of 75 dollars and are being asked to find the total cost after adding a tip, tax, and disc to the cost. To find this answer we will use the formula to calculate percentages making sure we use 75 as our base for each addition to our total cost.
Formula to calculate percentages:
[tex]\frac{p\times n}{100}[/tex]
First the disc:
[tex]\frac{10\times 75}{100}[/tex]
[tex]10\times75=750[/tex]
[tex]750\div100=7.5[/tex]
[tex]=7.5[/tex]
Next the tax:
[tex]\frac{7\times75}{100}[/tex]
[tex]7\times75=525[/tex]
[tex]525\div100=5.25[/tex]
[tex]=5.25[/tex]
Last but not least the tip:
[tex]\frac{20\times75}{100}[/tex]
[tex]20\times75=1500[/tex]
[tex]1500\div100=15[/tex]
[tex]=15[/tex]
Finally add:
[tex]75+7.50+5.25+15=102.75[/tex]
[tex]=102.75[/tex]
The total cost after adding the disc, tax, and the tip will be "$102.75."

y=(x + 4)(x+6)
y=(x +9)(x + 2)
y=(x + 7)(x+4)
Answer:
y = (x+8)(x+3)

This simplifies to x^2 + 11x + 24, same as the original question.
The graph of y=x² + 11x + 24 is equivalent to the y=(x+8)(x+3).
