mr. Smith took out a 54200 car loan at 10.2% compounded annually what would the interest be after 4 years
Answers
The compounded loan means that in the first year the 10.2% of interest is add to the initial 54200 and that value generate the next year the 10.2%
then in the first year the interest will be:
You use a rule of three:
[tex]\text{1st}=\frac{54200\cdot10.2}{100}=5528.4[/tex]As the first year the interest is 5528.4
To the second year that sum is added to the 54200 to get the interest:
[tex]54200+5528.4=59728.4[/tex][tex]2nd=\frac{59728.4\cdot10.2}{100}=6092.3[/tex]Third year:

if x is the number of years since 2000 and y is the percent of people using travel services the following equations represent the percent of people using travel agents and the percent of people using the internet to plan travel. y=-2x+30 y=6x+41 Find the year travel agents and the Internet were used equally
Answers
We need to solve a system of two variables with two equations, using elimination method.
y=-2x+30 (1)
y=6x+41 (2)
We are going to multiply first equation by 3, doing so the equation (1) can be written as:
3y = -6x + 90 (1)
Then, we are going to add the last equation to the second equation
3y = -6x + 90 (1)
+ y= 6x + 41 (2)
-----------------------------
4y = 131
y = 131 / 4 Isolating y
y= 131/ 4
Then, we replace y= 131/4 in the first equation and solve for x
[tex]\begin{gathered} \frac{131}{4}=-2x+30 \\ \frac{131}{4}-30=-2x\text{ Transposing 30 to the other side of the equation} \\ \frac{131}{4}-\frac{120}{4}=-2x\text{ Converting 30 to an improper fraction} \\ \frac{11}{4}=-2x\text{ Operating homogeneous fractions} \\ \frac{\frac{11}{4}}{-2}=-\frac{2}{-2}x\text{ Dividing by -2 on both sides of the equation} \\ -\frac{11}{8}=x \end{gathered}[/tex]Since -11/8 is equal to -1.4 and x represents the number of years since 2000, then the year travel agents and the Internet were used equally was 1998.

A family has 5 children. Assume that each child is as likely to be a boy as it is to be a girl. Find the probability that the family has 5 girls if it is known that the family's first child is a girl.
Answers
The required probability is 1/31 that the family has 5 girls if it is known that the family's first child is a girl.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Let us express every possible set of 5 children as a 5-letter word made up of the letters G or B. (G for a girl and B for a boy).
In all, 2⁵ = 32 such words are outcomes, with two options for each of the five slots.
The constraint "if it is known that the family contains at least one female" suggests that we would evaluate the reduced space of all such words, except the word (BBBBB).
This reduced event space is made up of 32-1 = 31 elements.
There is just one such term in the favorable collection of events (GGGGG).
As a result, the probability for the question is P = 1/31.

The function f(x)= -200x+1000 represents the altitude (in feet) of a paraglider x minutes from the time the paraglider begins a descent to a landing site located 100 feet above sea level. Identify the slope, domain, and range.
Answers
The slope of the Function is -200, the domain of the function is any real value of x and the range of the function is [1000,∞).
The provided function is,
f(x) = -200x+1000
This function is representing the altitude of a paraglider and time from where the paraglider descent. Here, x is representing time in minutes.
The landing site is located at the depth of 1000 feet.
we can write the function as,
y = -200x + 1000
Here, y is the range of the function.
As we observes the function, it is an equation of line,
So, the slope is equal to the coefficient of x.
So the slope is -200.
The domain is any value of x for which the function is defined,
as this it an equation of line,
The domain would be any real value of x.
The range is the output that we get after putting value of x.
Here,
Put x = 0.
y = -200(0)+1000
y = 1000
Now. putting x = -1,
y = -200(-1) + 1000
y = 1200.
Putting any negative value of x will make y positive,
So, the range will be [1000,∞)

These types of functions are called Piecewise-defined functions since it use a different formula for different parts of its domain because it has a point of discontinuity.
We have the following function:
[tex]f(x)=\begin{cases}-\frac{1}{3}x^2+4\rightarrow ifx\ne1^{} \\ \text{ 4 if x=1}\end{cases}[/tex]So, to find f(-4), we need to substitute x=-4 into the function for x≠1.

[tex]x=-4,x=1,x=5[/tex]These points coincide with the ones in the graph.
The expansion of this equation is:
[tex]f(x)=-x^3+2x^2+19x-20_{}[/tex]If we give some points to the equation at points x = -6, x = -3, x = 0, x = 3, x = 6, we have:
f(-6) = 154
f(-3) = -32
f(0) = -20
f(3) = 28
f(6) = -50
And all these values adjust to the proposed graph.
Therefore, the equation for option A would produce the proposed graph.

we have , three quarters means
we have 75 cents
and 75 cents = $0.75
we have 8 dimes ,
we know that 1 dime [tex]=[/tex] 10 cents
so , 8 dimes = 80 cents
and 80 cents = $0.80
we have six nickels,

So , The amount of money does Ahmad have left in the account after 11 trips on the toll roads is $ 48
b)
The number of trips on the toll roads can he take until his account is empty be n
when A ( t ) = 0
224 - 16t = 0
Adding 16t on both sides of the equation , we get
