A.48 : 60 : 35 : 42
4 : 5 : 5 : 6
B 16 : 13 : 13 : 16
16 : 13 : 13 : 16
C 22 : 33 : 14 : 21
2 : 3 : 2 : 3
D 25 : 28 : 5 : 7
25 : 28 : 5 : 7
Option C is the correct answer
If you picture a cylinder rolled out flat. there would be two circles for top and bottom and then a rectangle for the side. The rectangle would have width equal to height and length equal to circumference.
So then the areas of the pieces are added together to get total surface area.
= 2pi(3x-2)^2 + 2pi(3x-2)(x+3)
and you can simplify this is you want by multiplying through and combining like terms.
= 2pi(12x^2 - 5x -2)
or factor more to simplify the solution.
= 2pi(3x-2)(3x-2+x+3)
= 2pi(3x-2)(4x+1)
Answer:
this is your answer look it once
Answer:
There is only one zero for this function, and it takes place at x = 3
Which seems to agree with answer "c" in your list of options
Step-by-step explanation:
This is the equation of a line with a slope different from zero, therefore, there is only one zero (crossing of the x-axis) for it. We can find it by solving for x when y = 0:
y = - 3 x + 9
0 = - 3 x +9
3 x = 9
x = 9/3
x = 3
