________
x=12
Answer:
4x^2 + 3.
Step-by-step explanation:
f o g(x) = f(4x^2 + 4)
= (4x^2 + 4) - 1
= 4x^2 + 3.
Answer:
360 cm^2.
Step-by-step explanation:
Area of the base = 10*10 = 100 cm^2.
We find the slant height of the sides using Pythagoras:
h = sqrt ( 12^2 + 5^2)
h = sqrt 169
h = 13.
Area of the triangular sides = 4 * 1/2 * 10* 13
= 260 cm^2
So the total surface area = 100 + 260
= 360 cm^2.
Answer:
y+1=-5/7(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(4-(-1))/(-3-4)
m=(4+1)/-7
m=5/-7
m=-5/7
y-(-1)=-5/7(x-4)
y+1=-5/7(x-4)
