f(n) = -1.2n + 38.1
Hence, for an additional race
the finishing time, f(n+1), is given
f(n+1) = -1.2(n+1) + 38.1 = -1.2n + 38.1 -1.2
Which implies that
f(n+1) = f(n) - 1.2
This implies that the finishing time decreases by 1.2minutes

We need to find the longest sequence using the number 21 such that each number in the sequence must be a factor or multiple of the previous number.
Let the last number be 21.
The previous number of 21 must be a factor or multiple of 21.
From the given numbers we can only choose 7 as it is a factor of 21.
So, the sequence will be ...., 7, 21.
Now,
The previous number of 7 must be a factor or multiple of 7.
From the given numbers we can only choose 1 as it is a factor of 7.
So, the sequence will be 1, 7, 21.
There is not any previous number to 1.

Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks. To keep in shape, Tisha exercises at a track near her home. She requires 24 minutes to do 6 laps running and 3 laps walking. In contrast, she requires 20 minutes to do 6 laps running and 2 laps walking. Assuming she maintains a consistent pace while running and while walking, how long does Tisha take to complete a lap? Tisha takes minutes to run a lap and minutes to walk a lap.
Answers
Let R be the minutes Tisha runs and W be the minutes Tisha walks. Since she requires 24 minutes to do 6 laps running and 3 laps walking, we have the following equation:
[tex]6R+3W=24[/tex]Now, when she requires 20 minutes to do 6 laps running and 2 laps walking, we have:
[tex]6R+2W=20[/tex]So, we have the following system of equations:
[tex]\mleft\{\begin{aligned}6R+3W=24 \\ 6R+2W=20\end{aligned}\mright.[/tex]We are going to solve it by elimination. Notice that the coefficients of R are the same, so we just have to multiply one equation by -1 and add it altogether to the other equation:
[tex]\begin{gathered} (6R+2W=20)(-1) \\ \Rightarrow-6R-2W=-20 \end{gathered}[/tex]Then:
[tex]\begin{gathered} 6R+3W=24\rbrack \\ -6R-2W=20 \\ \Rightarrow(6R-6R)+(3W-2W)=24-20 \\ \Rightarrow W=4 \end{gathered}[/tex]Now we use the value W=4 to find R:
[tex]\begin{gathered} W=4 \\ 6R+3W=24 \\ \Rightarrow6R+3\cdot4=24 \\ \Rightarrow6R=24-12=12 \\ \Rightarrow6R=12 \\ \Rightarrow R=\frac{12}{6}=2 \\ R=2 \end{gathered}[/tex]Therefore, it takes Tisha to complete a lap 2 minutes if she's running and 4 minutes if she's walking.

Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the given values
[tex]\begin{gathered} Total\text{ payment}=242000 \\ down\text{ payment}=55\% \\ rate\text{ for compunding}=8.2\%=\frac{8.2}{100}=0.082 \\ n=2\text{ since it is compounded semi-annually} \\ t=5\text{ years} \end{gathered}[/tex]STEP 2: Find the mortgage value
[tex]mortgage\text{ }value=Total\text{ payment}-Down\text{ payment}[/tex]Down payment will be calculated:
[tex]\begin{gathered} 55\%\text{ of \$242000} \\ \frac{55}{100}\cdot242000=0.55\cdot242000=\text{ \$}133100 \end{gathered}[/tex]To calculate the mortgage value, we first calculate the compounded amount,
[tex]\begin{gathered} A = P(1 + \frac{r}{n})^{nt} \\ A=108900\cdot(1+\frac{0.082}{2})^{2\cdot5} \\ A=108900\cdot(1.041)^{10} \\ A=162755.3131\approx\text{ \$}162755.31 \end{gathered}[/tex]Hence, the mortgage value will be approximately $162755.31
Then we calculate the monthly payments
Number of months between 25 years will be:
[tex]\begin{gathered} 1\text{ year}=12\text{ months} \\ 25\text{ years}=25\cdot12=300\text{ months} \end{gathered}[/tex]Therefore, the monthly payments will be:

Im trying to plot a slope function on a graph y=2x+3
Answers
1) To plot a linear equation, like y=2x +3 let's visualize the graph
2) Set this function as an equation, to find the root of that function the x coordinate
y= 2x +3 Turn this to an equation
2x +3 =0 Subtract 3 from both sides
2x +3 -3 = -3
2x+0=-3 Divide both sides by 2
x=-3/2 -3/2 = -1.5
Looking at the function, we can see that the slope m=2, m>0, and the y-intercept is 3
Now we can set a table, where we can choose any value for x and then plug it into the function
x = 0 , y = 2(0) +3 y= 3
x= 1, y = 2(1) +3 y= 5
x=-1.5 y = 2(-1.5) +3 y=0

Determine the possible numbers of positive real zeros, negative real zeros, and imaginary zeros for the function. g(x) =x^5-2x^3-x^2+6
Answers
Step-by-step explanation:
Note: The term root and zero are used interchangeably.
Use Descartes Rule of Signs,
For the function, f(x), For every sign change, we have a positive root. If we have at least 2 positive roots, we either have that said number of roots or 2 less number of roots until we reach 0.
For example if we have 8 positive roots, we either have 8,6,4,2, or 0 positive roots
For the function f(-x), For every sign change we have a negative root.. If we have at least 2 negative roots, we either have that said number of roots or 2 less number of roots until we reach 0.
For example, if we have 7 possible roots, we either have 7,5,3,1 possible negative roots.
For g(x), we have 2 sign changes, so 2 positives root or none
[tex]g( - x) = ( - x) {}^{5} - 2( - x) {}^{3} - ( - x) {}^{2} + 6[/tex]
[tex]g( - x) = - {x}^{5} + 2 {x}^{3} - {x}^{2} + 6[/tex]
We have 3 sign changes, so we have 3 or 1 negative roots.
The degree of the polynomial tells us the max possible of zeroes. So the total number of zeroes is 5. That will always be the case for this polynomial so fill every row under the total number columns as 5.
The following possible combinations
2 positive zeroes, 3 negative zeroes, 0 imaginary zeroes
2 positive zeroes, 1 negative zeroes, 2 imaginary zeroes
0 positive zeroes, 3 negative zeroes, 2 imaginary zeroes
0 positive zeroes, 1 negative zeroes, 4 imaginary zeroes

Answers
The motion of the car (velocity and acceleration) based on the advertisement can be described as follows;
The initial velocity of the car is 0 m/s
72 km/h is equivalent to 20 m/s
The acceleration of the car is 1.6 m/s²
What is velocity and acceleration?Velocity is the rate of change of displacement
Acceleration is the rate of change of velocity with time
The car accelerates from rest indicates that the initial velocity of the car is 0 m/sThe speed to which the car accelerates to is 72 k m/h
To convert from km/h to m/s, the conversion factor is1000/3600
Therefore;
72 km/h = 72 × 1000/3600 m/s = 20 m/s
The speed of the car of 72 km/h is equivalent to 20 m/sAcceleration can be found from the rate of change of the velocity as follows;
[tex]Acceleration = \dfrac{Change\, in \, \, velocity}{Time}[/tex]
The time it takes the car to increase from 0 to 72 kph (20 m/s) = 12.5 seconds

Factoring 2nd-degree polynomials make use of the factors of the numerical coefficient of the first and last term.
The numerical coefficient of our first term is 49. The possible factors of 49 are 1 and 49, 7 and 7, -1 and -49, and -7 and -7.
The numerical coefficient of our last term is 36. The possible factors of 36 are 1 and 36, 6 and 6, 12 and 3, 4 and 9, -1 and -36, -6 and -6, -3 and -12, and -4 and -9.
Since the choices only show 1,7 and 6,6, we will only be focusing on these factors. Our goal here would be for us to have a result of +84 when the two pairs of factors are multiplied and then multiplied to two.
The second row gives us the middle term +84. Therefore, the factors of the polynomial are (7x + 6y)(7x + 6y). The answer is Option A.
