For exercises 14-19, find an equation for the line that satisfies the conditions

The no. of people own computer in 2015 are 92.0953 million.

The interest charged on a loan or deposit is known as compound interest. In our day-to-day lives, it is the concept we use the most. The amount's compound interest is based on both the principal and the interest earned over time. This is the primary distinction between simple and compound interest.

Given annually increase rate of computers = R =  23.2%

people own computer in 1990 = 1/2 million = 0.5 million

let no. of people own computer in 2015 be x

compound interest for annually increase in rate is p[tex](1 + R/100)^{t}[/tex]

where t = time and R = rate

Time = 2015 - 1990 = 25 years

x = 0.5(1 + 23.2/100)²⁵

x = 0.5(1.232)²⁵

x = 0.5 × 184.1906

x = 92.0953 million

Hence 92.0953 million people own computer in 2015.

He needs to sell $400,000 worth of goods.

Base salary = $30000

Percent Commission = 5%

Let the amount of goods that need to be sold be represented by x

Therefore, the equation will be:

30000 + (5% × x) = 50000

30000 + (0.05 × x) = 50000

30000 + 0.05x = 50000

Collect like terms

0.05x = 50000 - 30000

0.05x = 20000

x = 20000/0.05

x = 400000

Therefore, he needs to sell $400,000 worth of goods.

from the problem m = 1/2

point slope =

y -2 = 1/2(x+8)

We are given a parent function f(x) as:

       [tex]f(x)=\dfrac{1}{x}[/tex]

and the transformed function g(x) is given by:

       [tex]g(x)=\dfrac{1}{x+4}-6[/tex]

We know that the transformation of the type:

     f(x) → f(x+a)

is either a shift a units to the left or to the right depending whether a is positive or negative respectively.

Also, the transformation of the type:

   f(x) → f(x)+a

is the shift of the function f(x) either upward or downward depending on whether x is positive or negative respectively.

Here the function g(x) is:

     [tex]g(x)=f(x+4)-6[/tex]

This means that the function g(x) is a shift of the function f(x) 4 units to the left and then it is translated 6 units downward.

Also we may see by the graph.

Answer: [tex]-2\dfrac{1}{10}[/tex]

Step-by-step explanation:

The given expression to simplify : [tex]5\dfrac{1}{4}\div-2\dfrac{1}{2}[/tex]   (i)

First we convert mixed fraction into improper fraction as :

[tex]5\dfrac{1}{4}=\dfrac{5\times4+1}{4}=\dfrac{20+1}{4}=\dfrac{21}{4}[/tex]

[tex]-2\dfrac{1}{2}=-\dfrac{2\times2+1}{2}=-\dfrac{4+1}{2}=\dfrac{-5}{2}[/tex]

Now , put them in (i) , we get

[tex]\dfrac{21}{4}\div\dfrac{-5}{2}[/tex]

[tex]=\dfrac{21}{4}\times\dfrac{-2}{5}=\dfrac{-21}{10}=-\dfrac{20+1}{10}=-2\dfrac{1}{10}[/tex]

Hence, the required answer is [tex]-2\dfrac{1}{10}[/tex].

Answer:

Total rent costing for traveling for 4 days, 389 miles is $447.31

Step-by-step explanation:

Given : a car rental costs $35 per day plus $0.79 per mile.

We have to find the total rent costing for traveling for 4 days, 389 miles.

Since, Cost of car rent per day is $35

Thus, Cost of car rent for 4 days is $ 35 × 4 = $140

Also, Cost of car rent per miles is $0.79

Thus, Cost of car rent for  389 miles is $ 0.79 × 389 = $307.31

Thus, total car rental cost = Cost of car rent for 4 days + Cost of car rent for  389 miles.

Total car rental cost = $140 +  $307.31

Total car rental cost = $447.31

Thus, total rent costing for traveling for 4 days, 389 miles is $447.31

Step-by-step explanation:

In geometry, reflections and glide reflections are transformations that result in a preimage and an image with opposite orientations. This happens because a reflection flips an object over a line, creating a mirror image with reverse orientation. A glide reflection combines a translation and a reflection, also leading to opposite orientation.

In mathematics, particularly in geometry, when we talk about a preimage and an image, we refer to the original shape and the shape after transformation respectively. The transformation that results in a preimage and image with opposite orientations is reflections and glide reflections. A reflection is a transformation that flips a figure over a line, thus turning it into its mirror image. This reverses the orientation of the figure. A glide reflection involves a translation (or glide) followed by a reflection. Again, the result will have an orientation opposite to the original (or preimage).
