Find the other endpoint of the line segment with the given endpoint and midpoint. Endpoint: (-2, -6) Midpoint: (-5, 1)

Answers

Answer 1
Answer:

Answer:

(-8,8)

Step-by-step explanation:

The midpoint M(x_M,y_M) of the segment AB with endpoints A(x_A,y_A) and B(x_B,y_B) has coordinates

x_M=(x_A+x_B)/(2)\n \ny_M=(y_A+y_B)/(2)

In your case, A(-2,-6), \ M(-5,1), then

-5=(-2+x_B)/(2)\Rightarrow -2+x_B=-10,\ x_B=-10+2=-8\n \n1=(-6+y_B)/(2)\Rightarrow -6+y_B=2,\ y_B=2+6=8

Jason wants to fill a cylindrical water tank to its full capacity. He knows that the volume of the tank is equal to the product of , the square of the radius of the tank, and the height of the tank. Jason measured the height of the tank and found it to be 15 feet. He also measured the radius of the cylindrical tank and found it to be 10 feet.

Answers

Answer: the volume is 1500


Step-by-step explanation:

The answer is the product of the swuare of the radius of the tank (10^2) and the height. so it would be (10 x 10) x 15

A stretch of highway that is 12 1/4 miles long has speed limit signs every 7/8 of a mile.How many speed limit signs are on this highway? Please help!

Answers

12*4= 48
48 + 1 = 49
So there are 49 / 8 in the highway overall.
49  / 7 = 7
So there are 7 speed limit signs overall.

the probability of a radar station detecting an enemy plane is 62%. if 50 stations are in use what is the probability of exactly 35 stations detecting the enemy plane?

Answers

this is binomial probability with n=50 and p=0.62.

We want binom(50,0.62,35).

One way to calculate this is to use a calculator with statistical functions.

What isSlope-Intercept Form

Answers

Slope-intercept form is the formula:
Y=mx + b
The m= the slope
The b= the y-intercept
For example,
If you had the slope intercept form
Y=5x + 6
5= slope
6= y-intercept

the slope intercept form is the rate of change between any two points on a line it always is the same. The constant rate of change is called the slope of the line. Slope is the ratio of the rise, or vertical change, to the run, or horizontal change.                     

So Slope intercept form is basically Rise over Run.
