Answer:
f''(2) = 8
Step-by-step explanation:
f'(x)= 2x³ - 4x +3
f''(x)= 2*3x - 4= 6x - 4
f''(2)= 6*2 - 4 = 12 - 4 = 8
(7, -2).
Reflection will remain the same distance with the symmetrical line.

A pentagon needs 540 degrees in total to be a complete pentagon.
-----------------------------------------------
Solution:
Add all angles.
121 + 108 + 102 + 100 = 431
Subtract to 540.
540 - 431 = 109 degrees.
-----------------------------------------------
Answer:
x = 109 degrees

Using the formula for the perimeter and area of rectangle, the dimensions are: Length = 19 m; width = 9 m.
<h3>What is the Perimeter and Area of a Rectangular Shape?</h3>
Perimeter = 2(length + width)
Area = (length)(width).
Let x represent the length and y the width, therefore:
2(x + y) = 56 --> eqn. 1
xy = 171 --> eqn. 2
Rewrote eqn. 1
x + y = 56/2
x = 28 - y
Substitute x = (28 - y) into eqn. 2
171 = (28 - y)y
171 = 28y - y²
171 - 28y + y² = 0
y² - 28y + 171 = 0
Factorize
(y - 9)(y - 19)
y = 9 and y = 19
Therefore, the dimensions are: Length = 19 m; width = 9 m.

Answer:
48/80
Step-by-step explanation:
In order to get a denominator of 80, we need to turn the current denominator, 10, into 80. We do this by multiplying it by 8. We then have to multiply the top by 8 to keep it equal.
