Points of inflections are zeroes of the second derivative. We have:
So, the second derivative equals zero if and only if
So, this is the only point of inflection of this function.
Answer:
There are 14 4-point questions and 26 2-point questions.
Step-by-step explanation:
m = number of 4-point questions
n = number of 2-point questions
m+n =40
4m + 2n =108
You can solve system by elimination:
Multiply the 1st equation by -4 and keep the 2nd equation the same.
−4(m+n=40) → -4m -4n= -160
4m+2n=108 add them up
-2n = -52 divide both sides by -2
n = 26
plug it back in to solve for m
m + n = 40 →m + 26 =40 subtract 26 to both sides
m = 14

The value of sin 0 in quadrant 2 is 4/5
<h3>How to determine the identity</h3>
Given that cos 0 = -3/5
We have;
- adjacent = -3
- hypotenuse = 5
Let's find the opposite side, using Pythagorean theorem
5^2 = x^2 + (-3)^2
25 = x^2 + 9
collect like terms
x^2 = 25 - 9
x^2 = 16
x = √ 16
x = 4
We have that
sin 0 = opposite/hypotenuse
sin 0 = 4/5
It is important to note that the trigonometric identity 'sine' is positive in quadrant 2
sin 0 = 4/5
Hence, the value of sin 0 in quadrant 2 is 4/5
