Answer:
Radius 6.5cm
Diameter 13cm
Step-by-step explanation:
Diameter ia a straight line passing from side to side through the center a circle or sphere.
Radius formula is simply derived by halving the diameter of the circle
13/2=6.5
I think you write the equation wrong but I have tried
Because if the exponent is an even number, x can also be -x. For example, -4^2=4^2 but -4^3 isn't the same as 4^3
Step-by-step explanation:
1.
The given equation is :
6x+2y=14
We need to write it in the function form.
Taking 2 common from both sides,
2(3x+y)=2(7)
So,
(3x+y)=7
Subtract 3x from both sides,
y+3x-3x=7-3x
y = 7-3x
So, the correct option is (c).
2. f(x) = 3x-4
We need to find f(2). Put x = 2 in the above function.
f(2) = 3(2)-4
= 6-4
= 2
The correct option is (D).
