See below

Step-by-step explanation:

This equation is solved if one of the following 2 conditions is met

(x² + 1) / 10 is between 1 and 2

and

10 / (x² + 1) is between 0 and 1

<u>Solve this:</u>

1 < (x² + 1) / 10 < 2
10 < x² + 1 < 20
9 < x² < 19
3 < |x| < √19
x ∈ (- √19, - 3) ∪ (3, √19)

0 < 10 / (x² + 1) < 1
x² + 1 > 10
x² > 9
|x| > 3

Solution for this case is x ∈ (- √19, - 3) ∪ (3, √19)

(x² + 1) / 10 is between 0 and 1

and

10 / (x² + 1) is between 1 and 2

<u>Solve this:</u>

0 < (x² + 1) / 10 < 1
0 < x² + 1 < 10
- 1 < x² < 9
0 ≤ |x| < 3
x ∈ ( - 3, 3)

1 < 10 / (x² + 1) < 2
x² + 1 < 10 ⇒ x² < 9 ⇒ |x| < 3
x² + 1 > 5 ⇒ x² > 5 ⇒ |x| > √5

Solution for this case is x ∈ (- 3, - √5) ∪ (√5, 3)

The table below represents an exponential function, g, that has been vertically shifted from the parent function, f(x)= 2^x. Det

astra-53 [7]

Answer:

1. The size of shift from function f to function g is -12

2. The plot of the points of a function that is shifted only half as much as g from the parent function f is in the attached file in blue color.

Step-by-step explanation:

Parent function: f(x)=2^x

x=0→f(0)=2^0→f(0)=1

x=1→f(1)=2^1→f(1)=2

x=2→f(2)=2^2→f(2)=4

x=3→f(3)=2^3→f(3)=8

x=4→f(4)=2^4→f(4)=16

Size of the shift from function f to function g: s

s=g(0)-f(0)=-11-1→s=-12

s=g(1)-f(1)=-10-2→s=-12

s=g(2)-f(2)=-8-4→s=-12

s=g(3)-f(3)=-4-8→s=-12

s=g(4)-f(4)=4-16→s=-12

Points of a function h that is shifted only half as much as g from the parent function, f. Use the same x- values as used in the table for function:

s2=s/2→s2=(-12)/2→s2=-6

x h(x)

0 1+(-6)=1-6=-5

1 2+(-6)=2-6=-4

2 4+(-6)=4-6=-2

3 8+(-6)=8-6=2

4 16+(-6)=16-6=10

What is the future amount of 12,000 invested for 5 years at 14% compounded monthly?

Triss [41]

The total amount accrued, principal plus interest, with compound interest on a principal of $12,000.00 at a rate of 14% per year compounded 12 times per year over 5 years is $24,067.32.The amount of the initial loan, or principal, is multiplied by one plus the annual interest rate raised to the number of compound periods minus one to determine compound interest.

<h3 /><h3>what is compound interest?</h3>

To begin, change R from a percentage to a decimal, using the formula:

r = R/100 r = 14/100

r = 0.14 rate per year;

Next, find A by solving

A = P(1 + r/n)nt A = 12,000.00(1 + 0.14/12)(12). (5)

A = 12,000.00(1 + 0.011666666666667)(60) (60)

A = $24,067.32

Summary: The total amount accrued, principal plus interest, with compound interest on a principal of $12,000.00 at a rate of 14% per year compounded 12 times per year over 5 years is $24,067.32.

The amount of the initial loan, or principal, is multiplied by one plus the annual interest rate raised to the number of compound periods minus one to determine compound interest. You will then be left with the loan balance plus compound interest.
