Does anyone know how to do reverse percentages?
2 answers:
First, calculate the reduction of the price
reduction = normal price - sale price
reduction = 57 - 41.6
reduction = 15.4
The price decreased £15.4
Second, change the reduction of the price into percentage
percent = reduction/normal price × 100%
%
%
%
percent = 27.01%
The percentage reduction is 27.01% or approximately 27%
reduction = normal price - sale price
reduction = 57 - 41.6
reduction = 15.4
The price decreased £15.4

Answer: Choice D) x can be anything but 13
========================================================
Explanation:
The domain of is the same as the domain of g(x)
The domain for g(x) is saying we can plug in any number we want as long as it's not 13. This is to avoid dividing by zero. The same domain applies for the composite function because
and we can see that we still need to kick out x = 13 from the domain to avoid the division by zero issue.
Hi,
During halftime of a soccer game, a slingshot launches T-shirts at the crowd. A T-shirt is launched from a height of 5 feet with an initial upward velocity of 72 ft. Per second. The T-shirt is caught 34 feet above the field. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time.
<u>Write the general equation that represents height of the t-shirt as a function of time. </u>
f(t) = -16 + 72t + 5
2. <u>What is the maximum height of the t-shirt?</u>
<u />
1. <u>How long will it take the t-shirt to reach its maximum height?</u>
2,25 secondes
3. <u>The range describes which values of the graph? What would the range of this graph be? (Write in inequality and interval notation).</u>
height (y)
5 ≤ y ≤ 86 [ 5,86 ]
