larisa86 [58]3 years ago

Answer:

(1,0)

(5,24)

(-2,3)

Step-by-step explanation:

So we want y=x^2-1 per point.

Let's check them.

(0,1)? Plug in 0 for x and see what y is:

y=0^2-1

y=0-1

y=-1 which is not 1.

(1,0)? Plug in 1 for x and see what y is:

y=1^2-1

y=1-1

y=0 which is what we have for y.

(3,5)? Plug in 3 for x and see what y is:

y=3^2-1

y=9-1

y=8 which is not 5.

(5,24)? Plug in 5 for x and see what y is:

y=5^2-1

y=25-1

y=24 which is what we have for y.

(-2,3)? Plug in -2 for x and see what y is:

y=(-2)^2-1

y=4-1

y=3 which is what y is.

(-4,-17)? Plug in -4 for x and see what y is:

y=(-4)^2-1

y=16-1

y=15 which is not -17.

What does it mean when there is an open circle on a graph?
VladimirAG [237]
It means that the value will not be included. So if the open circle coincides with 2 on the x-axis then your limit will have x<2, which also means that the function is not continuous.

Ksenya-84 [330]

Answer:

244.92 square inches

Step-by-step explanation:

You just have to fill in the formula with the information they gave you.

They gave you the diameter for base circle so you divide that number in half to get the radius which is what you need for the formula represent as "r".

r=3

h=10

and you know pi is 3.14

so just plug in the numbers.

SA=2x3.14x3^2+2x3.14x3x10

SA=6.28x9+6.28x30

SA=56.52+188.4

SA=244.92
