The slope of any function is its first derivative.
If f(x)=x^2, then f'(x)= 2x .
At x=5, slope = f'(x) = 2(5) = <em>10</em> .
length is 8m
Width is 6.5m
<u>Explanation:</u>
Let, width = b
So, length = 2b-5
area = 52
We know,
area of rectangle = length X width
So, 
= 
On solving the above equation, we get
Width, b = 6.5m
length, l = 8m
Answer:
2x^2 +11
Step-by-step explanation:
f(x) = 3x^2 + 2 and g(x) = x^2 – 9
(f – g)(x) = 3x^2 + 2 -( x^2 – 9)
Distribute the minus sign
3x^2 + 2 - x^2 + 9
Combine like terms
2x^2 +11
x + 24 = first angle
x = second angle
4x = third angle
x + 24 + x + 4x = 180°
6x + 24 = 180°
6x = 180° - 24
6x = 156°
x = 156° ÷ 6
x = 26°....the second angle.
x + 24 = 26 + 24 = 50°.... the first angle.
4(26) = 104°
The largest angle is the third angle, which measures 104°.
