Answer 1
Answer:

Answer:

D

Step-by-step explanation:

Secant is hypotenuse / adjacent, while cosine is adjacent / hypotenuse. In fact, secant = 1/cosine.

Here, we know that cos(θ) = 2/19, so sec(θ) = 1/(2/19) = 19/2.

The answer is thus D.
Answer 2
Answer:

Answer:

D

Step-by-step explanation:

sec(theta) = 1/cos(theta)

= 1 ÷ 2/19

= 1 × 19/2

= 19/2

What is the average rate of change from x = −1 to x = 2?
A. −3
B. −1
C. 1
D. 3

Answers

we have

f(x)=x^(4)-4x

Step 1

Using the table find the value of f(x) for x=-1

x=-1\nf(-1)=5

Step 2

Using the table find the value of f(x) for x=2

x=2\nf(2)=8

Step 3

Find the average rate of change

we know that

the average rate of change is equal to the formula

(f(b)-f(a))/(b-a)

in this problem we have

f(b)=f(2)=8

f(a)=f(-1)=5

b=2

a=-1

substitute the values in the formula

(8-5)/(2+1)

(3)/(3)=1

therefore

the answer is the option C

the average rate of change is 1
A(x) = (f(x) - f(a))/(x - a) = (f(-1) - f(2))/(-1 - 2) = (5 - 8)/(-3) = (-3)/(-3) = 1
The answer is C.
