Step-by-step explanation:
Exponential Functions:
a=starting value = 14000
r=rate = 2.5%=0.025
Exponential Growth:
b=1+r=1+0.025=1.025
Write Exponential Function:
put it all together-
y=14000(1.025)^x
Plug in time for x:
y=14000(1.025) ^5
Evaluate-

Suppose that your boss must choose four employees in your office to attend a conference in Jamaica. Because all 19 of you want to go, he decides that the only fair way is to draw names out of a hat. What is the probability that you, Samuel, Lisa, and Andrew are chosen
Answers
Answer: the probability that I, Samuel Lisa and Andrew are chosen is 0.0003
Step-by-step explanation:
Given that;
Number of 4 employees are to be chosen from 19 of them;
so Number of ways to choose 4 employees from 19 employees = ?
we know that;
c(n,r) = [tex]\left[\begin{array}{ccc}n\\r\end{array}\right][/tex] = n! / ( r!(n-r)!)
so we substitute
c(19,4) = [tex]\left[\begin{array}{ccc}19\\4\end{array}\right][/tex] = 19! / ( 4!( 19-4 )!) = 3876
so the probability that I, Samuel Lisa and Andrew are chosen will be;
⇒ 1 / 3876 = 0.0002579 ≈ 0.0003
the probability that I, Samuel Lisa and Andrew are chosen is 0.0003

Answer:
Ur answer is in the screenshot :)
Step-by-step explanation:
1. Subtract 2x2x from both sides. 3y=5x-y-2x
3y=5x−y−2x
2. Simplify 5x-y-2x5x−y−2x to 3x-y3x−y.
3y=3x-y
3. Add yy to both sides.3y+y=3x
3y+y=3x
4. Simplify 3y+y3y+y to 4y4y. 4y=3x
4y=3x
5. Divide both sides by 33.\frac{4y}{3}=x34y=x
6. Switch sides.x=\frac{4y}{3}
x= 34y! Hope this helped!! :))

Find the gradient of the line segment between the points (1,-2) and (-2,10).
Answers
Given:
A line segment is between the points (1,-2) and (-2,10).
To find:
The gradient of the given line segment.
Solution:
We know that gradient of the given line segment means slope of the line segment.
The line segment between the points (1,-2) and (-2,10). So, slope of the line segment is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{10-(-2)}{-2-1}[/tex]
[tex]m=\dfrac{10+2}{-3}[/tex]
[tex]m=\dfrac{12}{-3}[/tex]
[tex]m=-4[/tex]
Therefore, the gradient of the given line segment is -4.
