Answer:
65000(1.02)^n.
Step-by-step explanation:
Salary = 65000(1.02)^n where n is the number of years he has worked for the company.
So after one year he earns $6500* 1.02 and after 2 years $65000 * 1.02^2.
The exponential function represents Mark's salary is [tex]65000(1.02)^n.[/tex]
What is an exponential function?The mathematical expression f(x)=exp or e^x denotes the exponential function.
The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to complex numbers or adapted to other mathematical objects like matrices or Lie algebras.
Given that Mark just landed a great job as an engineer where he will make $65,000 a year. The company he will work for guarantees a 2% pay increase each year so its employees' salaries keep up with inflation. At the end of the first year, Mark will have made $65,000.
The exponential function for the salary will be written as:-
[tex]Salary = 65000(1.02)^n[/tex]
where n is the number of years he has worked for the company.
So after one year, he earns $6500 x 1.02, and after 2 years $65000 x 1.02².
Therefore, the exponential function represents Mark's salary is [tex]65000(1.02)^n.[/tex]

Justo ayer fue el cumpleaños de Mauricio. Si a la edad e Mauricio, le sumo 13, al resultado le resto 10, luego al nuevo resultado lo divido entre 23 y finalmente le sumo 20, obtendré el número 21. ¿EN QUE AÑO nació mauricio?
Answer:
Mauricio nació en el año 2000.
Step-by-step explanation:
Supóngase que el cumpleaños se celebra en el año 2020, si [tex]x[/tex] es la edad actual de Mauricio, entonces la expresión matemática que traduce el enunciado del problema es:
[tex]\frac{(x+13)-10}{23} +20 = 21[/tex]
Ahora, se desarrolla y se simplifica la ecuación:
[tex]\frac{x+3}{23}+20 = 21[/tex]
[tex]\frac{x+3}{23} = 1[/tex]
Se despeja [tex]x[/tex]:
[tex]x +3 = 23[/tex]
[tex]x = 20[/tex]
Mauricio tiene 20 años.
Ahora, el año de nacimiento de Mauricio es la sustracción de la edad de Mauricio del año actual:
[tex]y = 2020-20[/tex]
[tex]y = 2000[/tex]
Mauricio nació en el año 2000.

A large western state consists of 3129 million acres of land. Approximately 55% of this land is federally owned. Find the number of acres that are not federally owned
Answer:
1408.5 acres
Step-by-step explanation:
If 55% of the land is federally owned, then 100 - 55 = 45% of the land is not federally owned.
We need to find how many acres are not federally owned, in other words, we need to find how many acres represent 45% of the total 3129 acres. So, to do this we can apply a rule of three:
3129 acres ---- 100%
x acres ------ 45%
[tex]x=\frac{(3129)(45)}{100} =3129(0.45)= 1408.05[/tex]
Therefore, the total of acres that are not federally owned are 1408.5 acres.
A store donates 3% of total sales to a charity. Mr. Winn bought 4 jackets at the store. Each jacket had a price of $150. How much money did the store donate to charity because of the jackets Mr. Winn bought?
Answer: The donated $18
Step-by-step explanation:
If each jacket cost $150 then multiply 150 by 4 to find out the total that the store received.
150 * 4 = 600
Now find 3% of 600 to find out how much they donated to the charity.
3% * 600 = $18
Hi May I know how to solve this?
Answer:
k = 3/4
Step-by-step explanation:
Parallel lines have the same slope so first, we need to find the slope of 8x + 6 = 2y. To do so, we can do the following:
8x + 6 = 2y
2y = 8x + 6
y = 4x + 3 (This is now in slope intercept form - y = mx + b where m = slope and b = y-int.)
Therefore, the slope is 4. Now, we can do:
3x = ky - 10
3x - 10 = ky
(3x / k) - (10 / k) = y
y = (3x / k) - (10 / k) (where k ≠ 0)
Now that the second line is in slope-intercept form, we can set the two x terms equal to each other, therefore:
3x / k = 4x
3x = 4x * k
3x / 4x = k
k = 3/4
why isnt 16:14 equivlant to 64:60
Answer:
The scalar used does not exist in the real number system.
Step-by-step explanation:
The ratio 16:14 is not equivalent to the ratio 64:60 because the scalar used does not exist in the real number system.
Note, that the ratio 64:60 can be scaled down by 4 to be the ratio 16:15, which is not the ratio 16:14.
In order to scale 64:60 to 16:14 or vise versa, you'd have to use a number that simply does not exist in the real number system.

Angle A and angle B are supplementary angles. If
angle B is 30° more than four times angle A, find
angle A and angle B.
Answer:
Angle A is 30
Angle B is 150
Step-by-step explanation:
So we have the supplementary angles A and B. In other words:
[tex]A+B=180[/tex]
We are also told that Angle B is 30 more than four times Angle A. In an equation, this is:
[tex]B=30+4A[/tex]
We now have a system of equations. Solve by substitution of B into the first equation:
[tex]A+B=180[/tex]
[tex]A+(30+4A)=180[/tex]
Combine like terms:
[tex]5A+30=180[/tex]
Subtract 30:
[tex]5A=150[/tex]
Divide by 5:
[tex]A=30[/tex]
So, Angle A is 30 degrees.
And since the angles are supplementary, this means that Angle B is 180 minus 30 or 150 degrees.

8 gal to 9 1/3 gal write ratio in lowest form with whole numbers in numerator and denominator
Answer:
[tex]\bold{\dfrac{6}{7}}[/tex]
Step-by-step explanation:
Given ratio is:
8 gal to [tex]9\frac{1}3[/tex] gal
To find:
Ratio in Lowest form with whole numbers in numerator and denominator.
Solution:
First of all, let us convert [tex]9\frac{1}3[/tex] to simple [tex]\frac{p}{q}[/tex] form:
Formula:
[tex]a\dfrac{b}{c} = \dfrac{a\times c+b}c[/tex]
Using the formula, we get:
[tex]9\dfrac{1}{3} = \dfrac{9\times 3+1}{3} = \dfrac{28}{3}[/tex]
Now, let us have a look at the ratio:
[tex]8 : \dfrac{28}{3}[/tex]
Any ratio, [tex]p:q[/tex] can be written as [tex]\frac{p}{q}[/tex].
Writing given ratio as per above:
[tex]\dfrac{8}{\dfrac{28}{3}}\\\Rightarrow \dfrac{8 \times 3}{28}\\\Rightarrow \dfrac{2\times 3}{7}\\\Rightarrow \bold{\dfrac{6}{7}}[/tex]
Therefore, the answer is
[tex]\bold{\dfrac{6}{7}}[/tex]

In a game experience, the experience of monsters, E, is measured by the formula E= 100M/L, where M=number monsters and L=level of monsters. Solve the formula for L
Answer: The formula solved for L is E/100M = L.
Step-by-step explanation:
So far we have the givens:
E, is measured by the formula E = 100M/L, where M = number monsters and L= level of monsters and solve for L.
Thus, isolate L to solve for it.
E = 100M/L

E/100M = L
Hence your answer!
Answer: 50M/E is correct
