Select all that apply. What are some uses for the distance formula? Finding the perimeter of polygons. Finding the area of recta
Gnesinka [82]

Answer:

Everything except the finding the midpoint

Step-by-step explanation:

If the question states the points of a shape, you can find the perimeter and the area of the polygon because you would know the dimensions and the lengths of each side, but in the options, it says the area of a rectangle, and it doesn't have to be a rectangle

You can find the equation of the circle, by finding the diameter of the circle and the radius. With the diameter, you would be able to find the centre of the circle and then you need to divide the diameter by two to get the radius.

For the midpoint, you use the midpoint formula. You just need to sub in the points into the formula and you would get the midpoint

When you are given two points on a graph (or worded problem), and it says that for every x number of km it uses y amount of gas and the question asks to find how much gas is needed in between these two points, you can do this. Find the distance between the two points and then use algebra to work out the amount of gas required

(x² + 16x)² = 17²

√x² + 16x)²  =  √17²
(x²  +  16x)   = (+-)17
1st equation: x²+16x-17 = 0
2nd equation:x²+16x+17 =0
Let's solve these 2 quadratic equation:
1st equation x' =1 & x" = - 17
2nd equation x'= (-8+√47) & x" =(-8-√47)
