FORMULA : Volume of the cylinder = πr²h
Volume = π x 4² x 3
Volume = π x 16 x 3
Volume = 150.8 ft³
Answer:
D) When x=2, y=14
When x=4, y=28
Step-by-step explanation:
By using slope= y2-y1/x2-x1
I get (1,7) and (3,21) from the table
slope= 21-7/3-1= 14/2= 7
Then I plug in the values into y=mx+b
7= 7(1) +b
b= 0
Getting an equation of y=7x
When x= 2
y= 7(2)= 14
When x= 4
y= 7(4)= 28
X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8
Answer:
3. undefined (vertical line)
4. 1
7. -4
8. 3
11. undefined (vertical line)
12. -1/3
Step-by-step explanation:
You can use the slope formula to calculate the slope which is (y2-y1)/(x2-x1)
3. (-4 - (-2)) / (6-6) denominator is 0 here so the slope is undefined (vertical line)
4. (7 - 1) / (-2 - (-4)) = 6 / 6 = 1
7. (1 - (-7)) / (2 - 4) = 8 / -2 = -4
8. (-1 - 5) / (0 -2 ) = -6 / -2 = 3
11. (3 - 0) / (-6 - (-6)) = 3 / 0 = undefined (vertical line
12. (2 - 3) / (-5 - (-2) = 1 / -3 = -1/3
Answer:
Step-by-step explanation:
Given
Required
Determine the solution
Make x the subject of formula in:
Divide both sides by 4
Substitute in
Solve the fraction
Open the bracket
Subtract 0.1 from both sides
Divide both sides by 0.2
Substitute 0 for y in
