So remember the formula for working out the slope:
(y2 - y1) ÷ (x2 - x1)
We already know two points:
(11, 5) and (20, 5) (Remember points are like (x, y)
Therefore y2 = 5 and y1 = 5 and x2 = 20 and x1 = 11
Substitute these into the formula from the start:
(y2 - y1) ÷ (x2 - x1)
(5 - 5) ÷ (20 - 11)
0 ÷ 9
And we can determine the slope is equal to 0 as 0 ÷ 9 = 0
Answer:
Step-by-step explanation:
f(x) = 2(x − 1)² + 3
= 2 ( x² - 2x +1) +3
= 2x² - 4x +2 +3
f(x) = 2x² − 4x + 5 .....standard form.
Answer:
50 pi cm^2
Step-by-step explanation:
the lateral surface area of a cylinder = 2×pi×r×h
from the values given: 2×pi×5×5
=50pi
2/3 + w = 1 1/2
get a common denominator, 6
2/3 * 2/2 = 4/6
1/2 * 3/3 = 3/6
4/6 + w = 1 3/6
subtract 4/6 from each side
w = 1 3/6 - 4/6
change the 1 to a common denominator of 6
w = 6/6+ 3/6 - 4/6
W = 9/6 - 4/6
w = 5/6
Answer w = 5/6
