The horizontal distance from the point where it was launched is 7.143.
We have given that,
The path of the marshmallow can be modeled by the quadratic y=−0.07x^2+x+2.2,
x represents the horizontal distance from the point it is launched, in feet.
<h3>What is the horizontal distance?</h3>
Horizontal distance means the distance between two points measured at a zero percent slope.
(1) Put x = 7.143 in given equation
y= -0.07(7.143)^2+7.143+2.2
y= 2.2
y= 5.771
We have to determine the what is its horizontal distance from the point where it was launched.
The value of x is called horizontal distance.
Therefore the horizontal distance from the point where it was launched is 7.143.

Hello from MrBillDoesMath!
Answer:
Domain = {All real number except for x = 5}
Discussion:
The domain of a function is all points where the function is defined. In this case, as division by zero is not allowed
. the domain is all real number except where x-5 = 0, i.e. x =5
Thank you,
MrB
The right answer is Option B.
Step-by-step explanation:
Given,
Amount of olive oil used for 4 servings =
Ratio of olive oil to servings =
Let,
x represents the amount of olive oil used for 20 servings.
Ratio of olive oil to servings = x:20
Using proportion
Ratio of olive oil to servings :: Ratio of olive oil to servings
Product of mean = Product of extreme
Dividing both sides by 4
Rachel will use cups of olive oil.
The right answer is Option B.
