What's the question?
(if its x-intercepts, its 1,-2,-5 since you use the zero product property)
Answer: $172.50
Step-by-step explanation: Method 1:
The original price of the item is $230.
The discount is 25%.
Let's find 25% of $230.
25% of $230 = 0.25 * $230 = $57.50
The discount amount is $57.50.
Now we subtract the amount of the discount from the original cost.
Sale price = $230 - $57.50 = $172.50
Method 2.
The original price is $230.
That means that $230 is 100% of the price since 100% of a thing means the entire thing.
Since the discount is 25% of the price, we subtract 25% from 100%, 100% - 25% = 75%.
The sale price is 75% of the original price.
Now we find 75% of $230.
75% of $230 = 0.75 * $230 = $172.50
Since the shape of the polygon is a square, all 4 sides have the exact same length. This means that Perimeter = 4 * length of one side, or;
Thus, the length(value) of S is

Answer:
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
Step-by-step explanation:
f(x) = -3x² +30x - 71
f(x) = -3(x² +-10x) - 71
f(x) = -3(x² +-10x+5^2-5^2) - 71
f(x) = -3(x² +-10x+5^2) -3(-5^2) - 71
f(x) = -3(x² +-10x+5^2) + 4
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
The value is 62.50
To the get whole value or 100 % of the value, we always divide the value to its corresponding percentage.
25 is the value; 40% is the percentage of 25 from the whole value.
25 / 40% = 62.50
In the event that the value of a part and the whole is given and the percentage is required. Simply divide the part by the whole to get its percentage of the whole.
whole = 62.50
part = 25
25 / 62.50 = 0.40 * 100% = 40%
If the whole value and the percentage is given. To find the value of the percentage, simply multiply the whole to the percentage.
whole = 62.50
percentage = 40%
62.50 * 40% = 25
