Answer: 44 gallons
Step-by-step explanation:
Using proportion,
33 gallons = 3hours
X = 4hours
Cross multiply
3 × X = 33 × 4
3X = 132
Divide bothside by 3
3x/3 =132/3
X = 44
Therefore the helicopter uses 44gallons for 4 hours.
The graph is Parabola or Graph of Quadratic Function.
The graph has minimum value, not maximum. So ( A ) is not correct for maximum part.
B is not correct for exponential part.
also C is not correct for discrete part as Quadratic graph is continuous.
So the answer is D.
For this case we define the following variables:
x: Number of party dresses
y: Number of suits
You have 30 hours per week to cut, that is, the first equation is given by:
It is also known that 25 hours per week are available for sewing, that is:
It has a system of two equations with two unknowns, solving we have:
Multiplying the second equation by -1:
Adding up:
Substituting x in the first equation:
Clearing and:
Thus, per week, the designer can produce 5 party dresses and 5 suits working at her maximum capacity.
Answer:
5 Party dresses
5 Suits
Answer:
See below.
Step-by-step explanation:
Let x equal each of the values on the table, and find the value of the function for that value of x.
f(x) = 5x - 5
x = -4
f(-4) = 5(-4) - 5
f(-4) = -20 - 5
f(-4) = -25
x = 0
f(0) = 5(0) - 5
f(0) = 0 - 5
f(0) = -5
x = 1
f(1) = 5(1) - 5
f(1) = 5 - 5
f(1) = 0
x = 3
f(3) = 5(3) - 5
f(3) = 15 - 5
f(3) = 10
x = 5
f(5) = 5(5) - 5
f(5) = 25 - 5
f(5) = 20
x f(x)
-4 -25
0 5
1 0
3 10
5 20
It is an enlargement because the scale factor is 2 and a half
