Answer:
Well. this is kinda trivial.
For a function f(x) = y.
The y-intercept is defined as the point where the graph of f(x) intersects the x-axis.
This always happens at x = 0.
So the y-intercept is equal to f(0).
Now, if we have the graph of f(x), you simply can see at what value of y does the graph intersect the x-axis, and that will be the y-intercept.
Answer:
4) 120π cm^2
5) 56π cm^2
6) 32π cm^2
Step-by-step explanation:
Surface Area of Cylinder = 2π
+ (2πr)(height)
(will use variable h for height)
4)
diameter = 8 cm
r = 0.5(diameter) = 0.5(8) = 4 cm
height = 11 cm
2π
+ (2π)(4)(11)
= 2π(16) + 2π(44)
= 32π + 88π
= 120π cm^2
5)
diameter = 8 cm
r = 0.5(diameter) = 0.5(8) = 4 cm
height = 6 cm
2π + (2π)(4)(6)
= 2π(16) + 2π(12)
= 32π + 24π
= 56π cm^2
6)
diameter = 6 cm
r = 0.5(diameter) = 0.5(6) = 3 cm
height = 7 cm
2π
+ (2π)(3)(7)
= 2π(9) + 2π(7)
= 18π + 14π
= 32π cm^2
Answer:
x=0
y=6
Step-by-step explanation:
3y- 12x = 18
2y-8x= 12
rearrange the equation
2y-8x=12
add 8x to both sides
2y=8x+12
divide both sides by 2
y=4x+6
now substitute it into 3y-12x=18
3(4x+6)-12x=18
simplify
12x+18-12x=18
simplify
18=18
x=0
substitute to find y
2y-8(0)=12
2y=12
y=6
Recheck:
3(6)-12(0)=18
18=18
2(6)-8(0)=12
12=12
