5t^-2 • 2t^-5
can someone write the steps? i can’t remember the formula so i’m stuck
Just multiply the numbers 5 and 2 to get 10. Then add the the exponent t and add the exponents together so you answer would be 10t^-7

The Fun Guys game rental store charges an annual fee of $5 plus $5.50 per game
rented.
The Game Bank charges an annual fee of $11 plus $2.50 per game.
For how many game rentals will the cost be the same at both stores?
Answer:
2 games
Step-by-step explanation:
Given data
The Fun Guys game
charges annual fee of $5 plus $5.50 per game
let the number of games be x
and the total charges be y
The expression for the total is
y=5+5.5x---------------1
The Game Bank
charges an annual fee of $11 plus $2.50 per game.
y=11+2.5x---------------2
Equate 1 and 2 above
5+5.5x=11+2.5x
collect like terms
5.5x-2.5x= 11-5
3x= 6
divide both sides by 3
x= 6/3
x= 2
It will take 2 games

Hi. I need help with these questions (see image)
Please show workings.
Question : Find the derivative with respect to x of each of the following:
(see image)
Answer:
see explanation
Step-by-step explanation:
Note that [tex]log_{e}[/tex] x = lnx ( natural logarithm)
Using the standard derivatives
[tex]\frac{d}{dx}[/tex] (lnx ) = [tex]\frac{1}{x}[/tex] , [tex]\frac{d}{dx}[/tex] ([tex]log_{a}[/tex] x ) = [tex]\frac{1}{xlna}[/tex]
Using the chain rule
Given y = f(g(x)) , then
[tex]\frac{dy}{dx}[/tex] = f'(g(x))) × g'(x) ← chain rule
(c)
y = [tex]log_{10}[/tex] (x² - 2) then
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{(x^2-2)ln10}[/tex] × [tex]\frac{d}{dx}[/tex] (x² - 2)
= [tex]\frac{1}{(x^2-2)ln10}[/tex] × 2x
= [tex]\frac{2x}{(x^2-2)ln10}[/tex]
(d)
y = ln([tex]\frac{1}{x}[/tex] )
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{\frac{1}{x} }[/tex] × [tex]\frac{d}{dx}[/tex] ([tex]x^{-1}[/tex] )
= x × - [tex]x^{-2}[/tex]
= x × [tex]\frac{-1}{x^2}[/tex]
= - [tex]\frac{1}{x}[/tex]
I can't find x y or z
Answer:
x = 4[tex]\sqrt{3}[/tex]
y = 6
z = 8
Step-by-step explanation:
keep in mind I'm not doing that well with geometry so this might all be wrong lol
x is part of a 30 60 90 triangle.
so x is 4[tex]\sqrt{3}[/tex]
next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.
4 + 6 = 10
10^2 = 100
100 = a^2 + b^2
y = 6 and z = 8 bc 36 + 64 = 100

Three students, Hunter, Gavin, and Levi, line up one behind the other. How many
different ways can they stand in line?
Answer:
Hunter, Gavin Levi
Levi, Gavin, Hunter
Gavin, Hunter, Levi
Hunter Levi Gavin
Levi Hunter Gavin
Gavin Levi Hunter
6 different ways
The number of different ways this can be done is 6 ways
Permutation and combinationGive the following students Hunter, Gavin, and Levi, line up one behind the other. They can line up in any form as they wish.
In order to line them up as they wish, we will take the factorial of the total student. In general;
n! = n(n-1)!
Since there are 3 students, the different ways can they stand in line is;
3! = 3 * 3 * 1
3! = 6
Hence the number of different ways this can be done is 6 ways

Step-by-step explanation:
A hobby store marks up remote-controlled cars 20%. The original price was $35. What is the retail price to purchase a remote-controlled car at the hobby store?
Answer:
The retail price to purchase a remote-controlled car at the hobby store is $42
Step-by-step explanation:
Original Price of remote controlled car = $35
Mark up = 20%
We need to find retail price.
First we will find mark up value i.e. 20% of 35 and then add it to the original price to find retail price.
Finding 20% of 35
[tex]20\% \:of\: 35\\=\frac{20}{100}\times 35\\=7[/tex]
So, mark up price is $7
Now, the retail price will be:
Retail price = Original Price + Mark up
Retail price = 35 + 7
Retail price = 42
So, the retail price to purchase a remote-controlled car at the hobby store is $42
How can I solve this problem using substitution, please show the work. (x,y)
y=x+8
x+y=2
Answer:
(-3,5)
Step-by-step explanation:
To solve using substitution, first isolate one variable in one of the given equations. Then, substitute the value you received from that equation for the matching variable in the second equation. Finally, substitute that value back into any of the equations to have both the x and y values.
1) The y in y = x + 8 is already isolated, so let's substitute that value for the y in x + y = 2. Substitute x + 8 for y in x + y = 2, then solve:
[tex]x + y = 2\\x + (x + 8) = 2 \\x + x + 8 = 2\\2x + 8 = 2 \\2x = -6\\x =-3\\[/tex]
Therefore, the x-value of the solution is -3.
2) Substitute the x value back into any of the one equations to find the value. Any choice is fine - in my work, I chose to substitute -3 for the x in y = x + 8:
[tex]y = x + 8 \\y = (-3) + 8\\y = -3 + 8\\y = 5[/tex]
Therefore, the y-value of the solution is 5.
3) Thus, the solution is (-3, 5).

Answer:
x = 12
Step-by-step explanation:
18:24 (comparing the same sides for the similar shapes; 18 and 24) when simplified down is equal to 3:4.
Using this 3:4 scale factor we can find the missing side x.
Solving for x :
[tex]\frac{3}{4}[/tex] × 16 = 12
x = 12
OR: Set up a proportion:
[tex]\frac{24}{16}[/tex] × [tex]\frac{18}{x}[/tex]
cross-multiply
16 × 18 = 288
24 × x = 24x
288 = 24x
x = 12

The graph of a line.
To find:
The slope of the line.
Solution:
From the given graph it is clear that the line passes through the points (1,7) and (3,5).
So, the slope of the given line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{5-7}{3-1}[/tex]
[tex]m=\dfrac{-2}{2}[/tex]
