10ft by 12ft = 120
12ft by 12 ft = 144
144-120 = 24 sq ft
You need 24 square feet.
Answer:
F(4) = 23
Step-by-step explanation:
Find F(4) also means finf F = 4x + 7 when x =4
When x = 4, it would be:
F = 4*4 +7
F = 16 + 7
F = 23
F(4) = 23
Hope it helped you :3
Answer:
780
Step-by-step explanation:
7.8 x 10 is 78. 1.0 x 10 is 10. Multiply both and get 780
y = -8x + 5
To obtain the equation we require a point on it and it's slope.
the slope m = dy/dx at x = 1
dy/dx = -2-6x
x = 1 then dy/dx = -2 -6 = -8
equation of line in form y - b = m(x-a) with m = -8 and (a,b)=(1,-3)
y + 3 = -8(x-1)
y + 3 =-8x + 8
⇒ y = -8x +5 is the equation of the tangent
