Answer:

Step-by-step explanation:

The average rate of change of the function f(x) is

$\dfrac{f(b)-f(a)}{b-a}$

1. At $a=1,$

$f(1)=2\cdot 1-1=1$

2. At $b=2,$

$f(2)=2\cdot 2-1$

The average rate of change is

$\dfrac{3-1}{2-1}=\dfrac{2}{1}=2$

The point given is on the terminal side of an angle theta. Find the exact values of the six trig functions of theta.. (-3,2)

Dima020 [189]

We can use SOH, CAH and TOA, but first we must find the length of a hypotenuse:
h = $\sqrt{(-3) ^{2}+2^{2} } = \sqrt{9+4}= \sqrt{13}$
sin (theta)= 2/√13
cos ( theta) = -3/√13
tan (theta) = -2/3
cot (theta ) = -3/2
sec (theta) = 1/cos(theta ) = -√13/3
csc(theta ) = 1/ sin (theta) = √13/2

Write 5/3 as a mixed number

Lostsunrise [7]

5 / 3 is improper fraction.
To change it into mixed fraction you have to divide 5 by 3.
i.e. 1 is the quotient, 3 is the divisor, 5 is the dividend, and 2 is the reminder.

To write it in the mixed fraction you will only need the quotient, remainder and divisor.
First you will write quotient in the middle then the remainder divided by divisor
i.e. 1 2/3 where 1 is quotient, 2 is remainder and 3 is divisor.
