Answer:

The expression

D = √(x2-x1)²+(y2-y1)

Distance between the two point is 8.06

Step-by-step explanation:

Given two points in space (x1,y1) and (x2,y2). The distance between this two points is calculated using the expression

D = √(x2-x1)²+(y2-y1)²

Given two points, the expression which gives the distance between the two points is described using the above formula.

Given the points (5,1) and (9, -6)

x1 = 5, y1= 1, x2 = 9, y2 = -6

D = √(9-5)²+(-6-1)²

D = √4²+(-7)²

D = √16+49

D = √65

D = 8.06

I believe you do
$x^{2} - x
 /y^{2} - y$

mel-nik [20]

Answer:

Step-by-step explanation:

The average is the total of the scores divided by 5.

128 x 5 Gives us the total scores of 640. I know that one bowler had a score of 160. I will subtract that from the total of 640. 640-160 = 480. Since the 4 bowlers left, all had the same score, I will divide 480 by 4 to get 120

For the graphed function f(x) = -(5)* - 3 + 2, calculate the average rate of change from x = 3 to x = 4.

Ilia_Sergeevich [38]

Answer:

-4

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is $\frac{f(b)-f(a)}{b-a}$

The given function is $f(x)=-5^{x-3}+2$ .

$f(4)=-5^{4-3}+2=-3$ .

$f(4)=-5^{3-3}+2=1$ .

The average rate of change from x=3 to x=4 is given by:

$\frac{f(4)-f(3)}{4-3}$

$\frac{-3-1}{4-3}=-4$

I need some help... HOW DO I DO THISSSS. NOT ASKING YOU TO DO IT JUST HELP ME

torisob [31]

so obviously first of all find three sherical objects or balls of varioius sizes to make it easier get a large medium and small sized.

then on scratch paper sketch those objects (im assuming by the looks of it you would trace them if not just draw them then take measuring tape or a ruler across to measure said object) now you arent told what units to measure in but id assume to stick with one unit either inches or cm

mesure the length across which is the circumference

now you would just have to do your calculations by finding the radius and volume and surface area

remember volume is (*units) cubed and suface area is (*units) sqared
