Step-by-step explanation:
since you said equation I'm assuming it's in terms of x and y Just as a general equation
since the centre of the circle isn't at 0, you have to take that into account using the formula above. solve for the radius of the circle by substituting (4,0) into the formula and get your r value to replace in the original formula
Answer:
the answer should be c. have a grand one
Distance of the person from the building (x)
tan 24 = 20/x => x = 20/tan 24 = 44.92 ft
The height of the building above the height of the person and the distance of the person from the building forms two legs of right angled triangle.
Therefore, if h is the height of the building, then;
tan 31 = (h-20)/44.92
h-20 = 44.92 tan 31
h = (44.92 tan 31) + 20 = 26.99 + 20 = 46.99 ft
I know that x=-3. So probably that second choice.
(g-f)(x)=g(x)=f(x)
(g-f)(x)=6x-4+x^2
(g-f)(x)=x^2+6x-4 then:
(g-f)(3)=3^2+6*3-4
(g-f)(3)=9+18-4
(g-f)(x)=23
