a.) The prism is reflected over the xz-plane.
Reflection Point P(x,y,z) over the xz-plane is P'(x,-y,z):
Reflection P(x,y,z) over the xz-plane → P'(x,-y,z)
Reflection A(0,0,0) over the xz-plane → A'(0,-0,0) = A'(0,0,0)
Reflection B(0,5,0) over the xz-plane → B'(0,-5,0)

Reflection D(3,0,0) over the xz-plane → D'(3,-0,0) = D'(3,0,0)
b.) The reflected image is then translated 2 units back, 3 units left, and 1 unit up.
Translation P'(x,-y,z) 2 units back, 3 units left, and 1 unit up is P''(x-2,-y-3,z+1):
Translation P'(x,-y,z) → P''(x-2,-y-3,z+1)
Translation A'(0,0,0) →A''(0-2,0-3,0+1) = A''(-2,-3,1)
Translation B'(0,-5,0) →B''(0-2,-5-3,0+1) = B''(-2,-8,1)

Answers
P = r x b
where: P = Percentage (Portion)
r = rate
b = base amount
1. Your given for number 1 is as follows:
rate = 8%
Base amount = $25.25
You are looking for how much you would pay in total. First you need to find out how much your going to pay in taxes, based on the base amount. To get that, you need to convert the rate in its decimal form by dividing it by 100.
rate = 8/100 = 0.08
Next you need to find how much you will pay in taxes, you can do that by using the formula:
P = r x b
= 0.08 x $25.25
= $2.02 This is how much you will pay in taxes.
To get the total amount you will pay, just add it to the original price:
$25.25 + $2.02 = $27.27
2. Your given will be:
p = 20
b = 25
r = ?
All you have to do is input what you know in the formula:
P = r x b
20 = r x 25
Transpose the 25 to the other side of the equation to get the rate and divide:
20/25 = r
0.8 = r
For this case it is asking for the rate in percent, all you need to do is multiply your computed rate by 100% and you will get 80%.
3. If your given would be:
P = $42.00
r = 70%
b = ?
Base is the unknown here, because you are looking for the original price. So we put this into our equation again:
$42.00 = 0.70 x b
Transpose the 0.70 to the other side of the equation again and divide:
$42.00/0.70 = $60.00
The original price was $60.00
4. The given would be:
P = ?
r = 7% or 0.07
b = $42,000
We are looking for how much he got, or the portion he got, so we are looking for the percentage. Input what you know into our formula:
P = 0.04 x $42,000
= $2,940.00
6. Your given would be as follows:
P = ?
r = 1.6% or 0.016
b = $800
You are looking for how much you would pay in finance charge, or the portion that will be added, based on your base amount so you will be looking for the percentage. Input your given into the formula:
P = 0.016 x $800
= $12.80
As for number 5, that is a trick question. The prices are different and no matter what formula you will use, you will not come up with a mathematical sound answer. Consider the situation, what can you buy in local hardware store that has 1, 12, and 144? The answer is HOUSE NUMBERS.
2. 80%
3. $60
4. $2,940
5. Ms. Jones was buying house numbers. Her house number was 112144. Each separate number would cost $.50. Therefore, the number 1 would cost $.50, the numbers 1 and 2 (12) would cost $1.00, and the numbers 1, 4, and 4 (144) would cost $1.50.
6. $12.80

The percentage of high school students who drink and drive was 17.5% at the beginning of 2001 and declined linearly to 10.3% at the beginning of 2011.†(a) Find a linear function f(t) giving the percentage of high school students who drink and drive in year t, where t = 0 corresponds to the beginning of 2001.f(t) = (b) If the trend continued, what was the percentage of high school students who drank and drove at the beginning of 2015? %
To find the linear function that represents the percentage of high school students who drink and drive in a given year, we can use the slope-intercept form of a linear equation. We can determine the slope and y-intercept by using the given data points. The linear function is f(t) = -0.82%t + 17.5%.
Explanation:To find a linear function f(t) giving the percentage of high school students who drink and drive in year t, we can use the slope-intercept form of a linear equation, which is y = mx + b. In this case, y represents the percentage of students who drink and drive, and t represents the year. We know that at the beginning of 2001 (t=0), the percentage was 17.5%, and at the beginning of 2011 (t=10), the percentage was 10.3%. Using this information, we can find the slope (m) and the y-intercept (b) of the linear function.
Step 1: Calculate the slope (m):
m = (y2 - y1) / (t2 - t1) = (10.3% - 17.5%) / (10 - 0) = -0.82% per year.
Step 2: Substitute one of the points and the slope into the slope-intercept form to find the y-intercept (b). Using the point (0, 17.5%):
17.5% = -0.82%(0) + b
b = 17.5%.
Therefore, the linear function f(t) is: f(t) = -0.82%t + 17.5%.
