Ted earned $4,300 from his summer internship that he plans to invest so that he can buy a used car after three years. Ted choose
olganol [36]

Answer: Yes he will be

Step-by-step explanation:

To find out if Ted can afford the car, find the future value of $4,300 in three years.

First convert the number of years and rates to quarterly values as this is the compounding period:

Term = 3 * 4 quarters = 12 quarters

Rate = 5.5% / 4 = 1.375% per quarter

Future value = Amount * ( 1 + rate) ^ term

= 4,300 * ( 1 + 1.375%)¹²

= $5,065.69

<em>Considering that Ted makes $5,065.69 in 3 years, he will be able to buy a car that costs $4,700.</em>

Use these functions a(x) =4x +9 and b(x) =3x -5 to complete the function operations listed below
Sloan [31]

Consider that we need to find (a+b)(x), (a-b)(x), (ab)(x),\left(\dfrac{a}{b}\right)(x).

Given:

The functions are:

a(x)=4x+9

b(x)=3x-5

To find:

The function operations (a+b)(x), (a-b)(x), (ab)(x),\left(\dfrac{a}{b}\right)(x).

Solution:

We have,

a(x)=4x+9

b(x)=3x-5

Now,

(a+b)(x)=a(x)+b(x)

(a+b)(x)=4x+9+3x-5

(a+b)(x)=7x+4

Similarly,

(a-b)(x)=a(x)-b(x)

(a-b)(x)=4x+9-(3x-5)

(a-b)(x)=4x+9-3x+5

(a-b)(x)=x+14

And,

(ab)(x)=a(x)b(x)

(ab)(x)=(4x+9)(3x-5)

(ab)(x)=12x^2-20x+27x-45

(ab)(x)=12x^2+7x-45

And,

\left(\dfrac{a}{b}\right)(x)=\dfrac{a(x)}{b(x)}

\left(\dfrac{a}{b}\right)(x)=\dfrac{4x+9}{3x-5}

Therefore, the required functions are (a+b)(x)=7x+4, (a-b)(x)=x+14, (ab)(x)=12x^2+7x-45 and \left(\dfrac{a}{b}\right)(x)=\dfrac{4x+9}{3x-5}.
