Can someone show me how to do it and the answer

Virty [35]

Answer:

Step-by-step explanation:

The equation of a circle is

(x-h)^2 + (y-k)^2 = r^2

h= 9, k = -7

r = 2, so r^2 = 4.

We now know that the equation must equal 4, so we can rule out answers A and C.

Plug in the values for h and k to get

(x-9)^2 + (y+7)^2 = 4

Choice B is correct!

Answer:

Equation: y = 2x + 25

Step-by-step explanation:

Here x determines the number of year. For the first year,we will see ( 2 * 1 ) = $2 increase. In the second year, ( 2 * 2 ) =$4 increase and like this goes on, whereas the $25 being constant. "y" determines the total cost for each year.

An isosceles trapezoid was broken into a rectangle and two triangles. What are the base and height of one of the triangles?

Serga [27]

Answer:

base = 2 m; height = 6 m

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

Given the information:

base of 8 meters
height of 6 meters
top side length of 4 meters.

=> the height of one of the triangles equal to the the height of the trapezoid = 6 meters

=> the base of the triangles:

= (the base of the trapezoid - the top side length) / 2

= (8-4)/2

= 2

So the base and height of one of the triangles : base = 2 m; height = 6 m

Hope it will find you well.
