Use the following table of the function f(x) = x4 − 4x to answer this question: x f(x)
-2 24
-1 5
0 0
1 -3
2 8
What is the average rate of change from x = −1 to x = 2?
A. −3
B. −1
C. 1
D. 3

Answers

Answer 1

Answer:

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 $1$

Answer 2

Answer: $A(x) = (f(x) - f(a))/(x - a) = (f(-1) - f(2))/(-1 - 2) = (5 - 8)/(-3) = (-3)/(-3) = 1$
The answer is C.

Andrew borrows $79,500 for 5 months on 6.30% interest rate in his saving account. calculate the simple interest

Answers

Equation i= p time r time T 79500 time .0630 time .42 Equal 21,035.7 simple interest Dos Doctor pepper on the interest, going back two time on the left which would become .0630 5 divide month of 12 which is .41666 Round to the nearest tenth which is .42

Final answer:

The simple interest on a $79,500 loan borrowed for 5 months at a 6.30% interest rate is $25,087.50.

Explanation:

To calculate the simple interest, we can use the formula: Simple Interest = Principal Amount * Rate * Time. In this case, the principal amount is $79,500, the rate is 6.30%, and the time is 5 months. First, convert the rate to a decimal by dividing it by 100: 6.30/100 = 0.063. Then, substitute the values into the formula: Simple Interest = $79,500 * 0.063 * 5 = $25,087.50.

If you have a semi-circle with a diameter of 8.6ft, what's the semi-circles area? Use the formula $\pi r^(2)$

Answers

So,

The diameter is 8.6ft. We need to convert to radius.

2 radius = 1 diameter

8.6/2 = 4.3 ft.

$\pi r{2}$

$\pi 4.3^(2)$

$\pi 18.49$

3.14(18.49)

58.0586ft.²

Divide by 2 (semi-circle)
29.0293ft.²
