Find the linear function for F in terms of H

F = -20h + 450

Step-by-step explanation:

To find the linear function, we will use the coordinate points (1, 430) and (2, 410)

Get the slope;

m = ΔF/Δh = 410-430/2-1

m = -20/1

m = -20

Get the y intercept b

Substitute m = -20 and (1, 430) into y = mx+b

430 = -20(1) + b

430+20 = b

450 = b

Swap

b = 450

Get the required equation

y = -20x + 450

replace x with h and y with F

F = -20h + 450

Hence the required equation is F = -20h + 450

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
