Answer:

A, E

Step-by-step explanation:

Solving for y, the coefficient of x tells us the slope of the given line.

y = (-x +50)/5

y = (-1/5)x +10 . . . . . the given line; has a slope of -1/5

The perpendicular line will have a slope that is the opposite reciprocal of this value:

m = -1/(-1/5) = +5

That is, you want equations for lines that have a slope of +5.

As above, the slope is the x-coefficient when the equation is in y = ( ) form. This fact lets us identify A as one good choice, and reject B–D as incorrect choices.

When we divide the equation of E by 5 to put it into the desired form, we have ...

y = 5x +2.6 . . . has a slope of 5

The equations of interest are ...

A. y = 5x +2
E. 5y = 25x +13

1. The diameter of a sphere is 21.6 cm. The volume of the sphere is __

sveta [45]

Detailed Answers:

Volume of a Sphere (V) = 4/3 πr^3

1. Diameter (d) = 21.6 cm
Radius (r) = 21.6/2 = 10.8 cm

Therefore,
= 4/3 πr^3
= 4/3 * 22/7 * (10.8)^3
= 4/3 * 22/7 * 1259.712
= 88/21 * 1259.712
=> 5278.79

Volume (V) = 5278.79 cm^3

2. Diameter (d) = 16 cm
Radius (r) = 16/2 = 8 cm

Therefore,
= 4/3 πr^3
= 4/3 * 22/7 * (8)^3
= 4/3 * 22/7 * 512
= 88/21 * 512
=> 2145.52

Volume (V) = 2145.52 cm^3

3. Diameter (d) = 24 cm
Radius (r) = 24/2 = 12 cm

Therefore,
= 4/3 πr^3
= 4/3 * 22/7 * (12)^3
= 4/3 * 22/7 * 1728
= 88/21 * 1728
=> 7241.14

Volume (V) = 7241.14 cm^3

4. Diameter (d) = 6 cm
Radius (r) = 6/2 = 3 cm

Therefore,
= 4/3 πr^3
= 4/3 * 22/7 * (3)^3
= 4/3 * 22/7 * 27
= 88/21 * 27
=> 113.14

Volume (V) = 113.14 cm^3
