Find the x - and y - intercepts of the line. X + 3y=6Y intercept: ( , )X intercept: ( , )
pantera1 [17]

ANSWER:

Y intercept: (0, 2)

X intercept: (6, 0)

STEP-BY-STEP EXPLANATION:

We have the following equation:

x+3y=6

The x-intercept is when y is equal to 0 and the y-intercept is when x is equal to 0, therefore:

\begin{gathered} \text{ x-intercept } \\ x+3\cdot0=6 \\ x=6\rightarrow(6,0) \\ \text{ y-intercept } \\ 0+3\cdot y=6 \\ y=\frac{6}{3}=2\rightarrow(0,2) \end{gathered}

What shape is the cross section formed by the intersection of a cone and a plane parallel to the base of the cone?
Ksju [112]
<h2>Answer:</h2>

A circle

<h2>Step-by-step explanation:</h2>

The representation of this problem is shown below. The cross-section is the name for a slice that cuts through a solid. If we move around the height of the cone through its volume, we will find that at every point the cross section will be a circle. The radius of that circle will depend on the point we are on. On the base of the cone, the circle will have the same radius of the cone and the radius will be decreasing when moving until we get to the apex.

Sarina throws a ball up into the air, and it falls on the ground nearby. The ball's height, in feet, is modeled by the function
tangare [24]

Answer:

(C) 3 feet

Step-by-step explanation:

We have a function of f(x) here. When Sarina throws the ball, it has been 0 seconds since she threw it.

Since x represents the amount of seconds, we can find the height of the ball (f(x)) by substituting x in as 0.

-0^2 - 0 + 3

0 squared is 0, 0 minus zero is 0, and 0+3 = 3, so

f(x) = 3

Meaning that when Sarina threw the ball, it's height was 3 feet.

Hope this helped!
