Find the mindpoint of ab a(-3,7) and b(-7,-6)

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

The midpoint of AB is (-5,1), if A(-3,8) and B(-7,-6). How to find out the midpoint of coordinates?The midpoint of coordinates is found by measuring the distance between two endpoints and dividing the obtained result by 2. Apart from this, one more method is there which is to add the two X-coordinates of the endpoints and divide them by 2. The same concept is applied to the Y-coordinates as well. According to the question, A = (-3,8) and B = (-7,-6). The formula is as follows:M(x,y) = ((x₁+x₂)/2 , (y₁+y₂)/2). Putting the above values in the mentioned formula, we get:M(x,y) = ((-3-7)/2 , (8-6)/2).

M(x,y) = (-5 , 1). Therefore, the midpoint of AB is (-5,1), if A(-3,8) and B(-7,-6).To learn more about the Midpoint of coordinates, refer to the link: brainly.com/question/28308761

Find the area of a regular pentagon with radius 9mm

Answers

The required area of pentagon is 212.36 mm².

What is area of a shape?

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

Given that,

radius of pentagon = 9 mm

Since in pentagons there are 5 sides.

Therefore,

Area is =  (5/4)x s² x tan(π/5)

Where s is the pentagon's length along one side.

Use the pentagon's radius to get s using the following calculation

since we already know,

S = 2x radius x sin(π/5)

When we enter the values ,

we obtain: s = 2 x 9 x sin(π/5)

                    = 14.56 mm.

We can now enter this value of s into the area formula as follows:

Area  = (5/4) x s² x tan(π/5)

          = 212.36mm².

Consequently, the regular pentagon's area with a 9 mm radius is roughly 212.36 mm²

#SPJ2

The area is calculated by using the formula A=(r^2)*n*sin(360/n)/2 where n is the number of sides which is 5 for pentagon and r is the radius which is 9 mm. So, using the formula, the answer is 51.4 mm^2.

The cost to rent a moving truck is a flat fee of $25 plus $0.60 per mile. The equation c = 25 + 0.6m models the cost, c, in dollars for the number of miles, m, traveled in the truck.

Answers

Answer:

Miles Traveled is independent.

Cost is the dependent.

Step-by-step explanation:

Hope this helps!!

I’m not entirely sure what the question is here, but all you would have to do is plug a given number of miles into m to find the cost. Or, if you’re trying to find the amount of miles driven, simply substitute the cost for c and solve for m. You would do this by subtracting 25 from both sides and then dividing by .6

WILL CHOOSE YOUR ANSWER AS BRAINLIEST!!The height of a 0.5-liter orange juice box with a square base is a function of the width of its base,



h=(500)/(w^2)



where w is the width of the base in centimeters. Find the width of the juice box if its height is 20 centimeters.



w =_____cm

Answers

Answer:

5 cm

Step-by-step explanation:

It is given in the question that height and width of the orange juice box are related as:

h=(500)/(w^(2))

We have to find the width when h=20 cms

20=(500)/(w^(2))

w^(2)=(500)/(20) =25 (cm)^(2)

∴w=±5 cm

But width cant be negative,hence w=5 cm.
