Answer:

Step-by-step explanation:

(x - 4)/2 = 5

x - 4 = 10

x = 14

(y - 10)/2= -8

y - 10 = -16

y = -6

(14, -6)

The volume of a cone is 20pi cubic meters. What is the volume of a cylinder with the same base and height?

Sergeu [11.5K]

Recall, the volume of a cone is 1/3pi times radius of base times height.
$V cone_{} = \frac{1}{3} * \pi *r^2*h$

Volume of a cylinder is the same but without the 1/3
$V cyl_{} = \pi*r^2*h$

It gives you the cone volume 20pi and that the radius and height of both of them are the same values.
$20 \pi= \frac{1}{3} \pi r^2h$
$V cyl_{}= \pi r^2h$

since it says the radius and height are the same for both , you can equate the two, you can solve both equations for r^2*h and then equate what is on the other side.
$60=r^2h
$
$\frac{V}{ \pi } =r^2h$

so
$60= \frac{V}{ \pi }$
$V=60 \pi$

What is the equation of the graph below? A graph shows a parabola that opens up and crosses the x axis at negative two and negat

Anastaziya [24]

Answer:

$y=(x+3)^{2} -1$

Step-by-step explanation:

General equation of a parabola that opens up is $y=a(x-h)^{2} +k$ , a>0

So equation becomes $y=(x-h)^{2} +k$ which implies option A and option B can never be true for this parabola.

Also this parabola's vertex lies in 3rd quadrant where coordinates of both x and y will be negative.

So, the equation of parabola will be of the form $y=(x+h)^{2} - k$

Hence, option 4 that is $y=(x+3)^{2} -1$ is correct.

What is the linear function equation that best fits the data set?

slavikrds [6]

Answer:

Option 3

Step-by-step explanation:

Given data set is,

{(1.5, 1), (2.5, 3), (3, 3), (3, 5), (3.5, 5), (4.5, 7), (5, 7), (5, 9), (5.5, 9), (6.5, 11), (7.5, 13)}

By using linear regression calculator,

Equation of the linear function will be,

y = 2x - 2

Therefore, Option 3 will be the correct option.
