What is the distance between points (4, −7) and (−5, 9)? Round to the nearest tenth of a unit.
Answers
they are 18.4 units away from eachother
Here is the distance formula; hopefully that helps. Note that the whole formula is square rooted! d= \sqrt{( x_{2}- x_{1) } }{2} ( y_{2} - y_{1} ){2} [/tex]

What is the value of angle C figure 2
Answers
the answer is 105 for the angle
Sum of interior angles in a triangle = 180° C + 30° + 45° = 180° C + 75° = 180° C = 180° - 75° C = 105°
Answer: The value of angle C = 105°
A salesperson at a furniture store earns a 3% commission on all sales. How much commission does the salesperson earn on a $1400 sale?

The circumference of the bas of the cylinder is 18π units. The cylinder is 30 units tall.Which of the following is the closest to the volume of the cylinder? A 706 cubic units B 1,414 cubic units C 7,630 cubic units D 21,195 cubic units
Answers
The volume of a cylinder is (pi) (radius)² (height).
We know the height, but we don't know the radius. Is there a way we can find it ? We know the circumference of the base. Maybe that's a clue. Can you find the radius of a circle when you know the circumference ?
Circumference of a circle = (pi) x (diameter)
18 pi units = (pi) x (diameter)
Divide both sides by pi : 18 units = diameter
Divide both sides by 2 : 9 units = radius yay !
Now we know the radius and the height of the cylinder, so we can calculate the volume.
radius = 9 height = 30 we'll use 3.14 for pi .
Volume = (pi) (radius)² (height) =
(3.14) (9)² (30) =
(3.14) (81) (30) = 7,630.2 cubic units
Is there a choice close to that ? I'll go up and look.
