Answer:
Step-by-step explanation:
He added 
, so you need to include it, the new expression now being
You need to simplify the polynomial first (combine all like terms) and it should become
The only option that actually exists are A and D, the answer would be D though because the letters that come first in the alphabet have more priority
The answer is very simple to get if you have a calculator. You first multiply
and
. You should get 26.46, now you move one decimal to the front which means you are multiplying 10 to it. Now you can refer the rest from below:
Add the powers of ten
This is your answer =)
Volume of a cylinder = πr²h
Volume of the cylinder = π (2 3/16)² (3)
Volume of the cylinder= 45.10 in³
Answer: 45.10 in³
Answer-
y = -1x or y = -x
Explanation-
Step 1: Look for a pattern in the x column and the y column.
X = -1, 3, 7, 11
(The pattern is that you add 4 with every number)
Y= 0, -4, -8, -12
(The pattern is that you subtract 4 with every number)
Step 2: Create and (if needed) simplify the slope
Slope = y/x
Slope -> -4/4
Simplified Slope -> -1
Step 3: Put it in slope-intercept form
Slope-intercept form -> y = mx + b
y = -1x + 0 -> y = -1x or y = -x
You plug in numbers -3 to 3 into the x variable of the equation and then plot those points
y = -2x
X = -3 y = (-2)(-3) = 6
X = -2 y = (-2)(-2) = 4
X = -1 y = (-2)(-1) = 2
X = 0 y = (-2)(0) = 0
X = 1 y = (-2)(1) = -2
X = 2 y =(-2)(2) = -4
X = 3 y = (-2)(3) = -6
In case that looks a little cluttered here are the points to graph:
(-3, 6) (-2, 4) (-1, 2) (0, 0) (1, -2) (2, -4) (3, -6)
