1. $2,520.00
2. 0.0%
3. 3%
4. $661.5
5. $727.00
6. $1,736.96
8. $3,250.00
10. 2%
Step-by-step explanation:
1.
We solve for the original price by solving first for the reverse value of the %off.
In this case we have 2.0% off. To find the reverse value, we first need to convert it to its decimal form.
r = 2.0% or 0.02
Now we solve for the rate by subtracting r to 1.
r = 1 - 0.02
r = 0.98
Now that we have r we divide the discounted price by r.
Original price = 2,469.60 / 0.98
Original price = $2,520.00
2.
Pretty straight forward as the Original price and the Discounted are the same. So there is no discount.
r = 0.0%
3.
To find the rate we first need to subtract the original price to the discounted price to find the decrease.
$850 - $824.50 = $25.50
Now that we have the decrease we can find the rate by using this formula:
4.
To find the discounted price we simply multiply the original price to the r and subtract the amount to the original price.
5.
Since the %off is 0.0% then the discounted price is equal to the original price.
$727.00
7.
To find the discounted price we simply multiply the original price to the r and subtract the amount to the original price.
8.
We solve for the original price by solving first for the reverse value of the %off.
In this case we have 3.0% off. To find the reverse value, we first need to convert it to its decimal form.
r = 3.0% or 0.03
Now we solve for the rate by subtracting r to 1.
r = 1 - 0.03
r = 0.97
Now that we have r we divide the discounted price by r.
Original price = 3,152.50 / 0.97
Original price = $3,250.00
10.
To find the rate we first need to subtract the original price to the discounted price to find the decrease.
$4,567.00 - $4,475.66 = $91.34
Now that we have the decrease we can find the rate by using this formula:
You need 3 points to graph a quadratic function.
It is advisable that one of these points be the vertex, because the line of symmetry passes through it
Next, you need to find two other points that lie on the curve, replacing an x-value into the function and calculating the y-value. It is easier if these two points are at the same distance from the line of symmetry.
For example, if the quadratic function is y = (x - 4)² + 3, the vertex is located at (4, 3). Replacing with x = 3 into the equation, we get:
y = (3 - 4)² + 3
y = 1 + 3
y = 4
Replacing with x = 5 into the equation, we get:
y = (5 - 4)² + 3
y = 1 + 3
y = 4
Now, we need to connect the points (3, 4), (4, 3), and (5, 4) with a U shape, as follows:
