Hello Johnson!
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x - intercepts: (9,0), (5,0), (4,0)
y - intercepts: (0, -180)
Good luck!

The y-intercept is already given an the equation.
It is negative 180.
The x-intercepts or roots where y = 0, are 4, 9, and 5. You know that there are three roots because the highest degree of the function is 3.
If you have a graphing calculator, I suggest plugging in the function to see the shape of the graph.

<h3>The area of base is 0.25 square meter</h3>
<em><u>Solution:</u></em>
Given that,
The capacity of a cylindrical fuel tank is 2.5 kl and its height 10 m
To find: area of base
<em><u>The volume of cylinder is given as:</u></em>
The area of base of cylinder is area of circle
Therefore,
From given,
h = 10 m
v = 2.5 kl
1 kilo liter = 1 cubic meter
Therefore,
2.5 kl = 2.5 cubic meter
Substitute height = 10 and volume = 2.5
Thus area of base is 0.25 square meter
Answer:
Therefore the company have to print either 47 or 12 t-shirt for its production cost to be $40 or less.
Step-by-step explanation:
Given that,
The function that models the production cost is
To find the number of t-shirt, we put f(t)=40 in given function.
∴40= 0.1t²-6t+100
⇒ 0.1t²-6t+100-40=0
⇒0.1 t²- 6t +60=0
⇒t²-60t+600=0
Applying quadratic formula , a=1, b= - 60 and c=600
= 47.32,12.67
≈47, 12
Therefore the company have to print either 47 or 12 t-shirt for its production cost to be $40 or less.
