X-intercept and y-intercepts og y=x^2-3
Rufina [12.5K]

Answer:

Part 1) The y-intercept is the point (0,-3)

Part 2) The x-intercepts are the points (-\sqrt{3},0)\ and\ (\sqrt{3},0)

Step-by-step explanation:

we have

y=x^{2}-3

This is a vertical parabola open upward

step 1

Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

y=(0)^{2}-3

y=-3

The y-intercept is the point (0,-3)

step 2

Find the x-intercepts

we know that

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

x^{2}-3=0

solve for x

Adds 3 both sides

x^{2}-3+3=0+3

x^{2}=3

take square root both sides

x=(+/-)\sqrt{3}

so

The x-intercepts are the points (-\sqrt{3},0)\ and\ (\sqrt{3},0)

The ice cream parlor serves spherical scoops of ice cream with a radius of 1 in. What is the approximate volume of 2 scoops of i
Varvara68 [4.7K]

Answer: 8.37 in³

Step-by-step explanation:

Given the following :

Shape of icre cream scoop = sphere

Radius (r) = 1 inch

Volume of a scoop of icecream = volume of sphere :

4/3πr³

(4/3) × 3.14 × 1³

1.333 × 3.14 × 1

= 4.1867 in³

Hence, the volume of 2 scoops of ice cream will be :

2 × ( volume of a scoop of ice cream)

(2 × 4.1867) in³

= 8.37 in³

Please answer as soon as possible, im in a bit of a hurry.
12345 [234]

Easy bruh

Answer:

6w^3

Step-by-step explanation:

It can't be any answer with cubed in it because that would be volume. So, A and C magically vanish. If we know that the length of a cube is w that means that all sides are w. There are six faces on a cube. If we want to find surface area we will have to add up the area of all faces. the area of one face will be w^2. We multiply that number by six and we get 6w^3.
