Answer:

803.84

Step-by-step explanation:

because its pi x r² x height

in this case the radius is 4 because the diameter is 8 and half would be 4 so its 4² which is 16 and the height is 16 and you mulitply pi which is 3.14 so 16 x 16 x 3.14= 803.84cm

A pair of equations is shown below:

y = 7x − 8
y = 5x − 2

Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.

Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer

Answers

Answer:

Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.

y=7x-8

y=5x-2

7x-8=5x-2

   +8     +8

-----------------

7x=5x+6

-5x  -5x

----------------

2x=6

/2   /2

-----------

x=3

y=7x-8

y=21-8

y=13

Part B) The lines will intersect at point (3, 13)

Step-by-step explanation:

hope this helps

so sorry if this is wrong

did this for hw

Answer:

Step-by-step explanation:

part a:

substitution

7x - 8 = 5x - 2

2x - 8 = -2

2x = 6

x = 3

y = 7(3) - 8 = 21 - 8 = 13

y = 13

100 POINTS AND BRAINLY NO LINKS What is the length of the line segment with endpoints (−3, −8) and (10, −8) ?

Answers

Answer:

13 units

given two points: (−3, −8) and (10, −8)

As the y coordinates are same.

use the method:

|x2| + |x1|  where  (x1, y1), (x2, y2)

Solve:

|10| + |-3|

10 + 3

13

Answer:

10 units

Step-by-step explanation:

[tex](x_1,y_1)=(-3,-8)[/tex]

[tex](x_2,y_2)=(10,-8)[/tex]

We are supposed to find the length of the line segment with endpoints (−3,8) and (7, 8)

We will use distance formula : [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute the values :

[tex]d=\sqrt{(10+3)^2+(8-8)^2}[/tex]

[tex]d=\sqrt{100}[/tex]

[tex]d=10[/tex]

Hence the length of the line segment with endpoints (−3,8) and (7, 8) is 10 units
