Step-by-step explanation:
The revenue, Y, received for selling, t, DVD players is given by the equation: Y = -1/1000 t^2 + 10t. Find the number of DVD players that must be sold to obtain the maximum revenue.
The equation Y = -1/1000 t^2 + 10t is an illustration of a quadratic function
The number of DVD players that must be sold to obtain the maximum revenue is 5000
How to determine the number of DVDs?The equation of the function is given as:
[tex]Y = -\frac 1{1000} t^2 + 10t[/tex]
Differentiate the function
[tex]Y' = -2 * \frac 1{1000} t + 10[/tex]
Set to 0
[tex]-2 * \frac 1{1000} t + 10 = 0[/tex]
Simplify
[tex]- \frac 1{500} t + 10 = 0[/tex]
Subtract 10 from both sides
[tex]- \frac 1{500} t = -10[/tex]
Multiply both sides by -500
[tex]t = 5000[/tex]
Hence, the number of DVD players that must be sold to obtain the maximum revenue is 5000

Lexi ran 2/4 of a mile in 1/10 of an hour. At this rate, in how long does she run one mile?
Answer:A runner ran 20 miles in 150 minutes. If she runs at that speed,. How long would it take her to run 6 miles? ... How fast is she running in miles per hour? ... experience in reasoning with equivalent ratios and unit rates from both sides of the ratio.
Step-by-step explanation:
Answer:
0.2 hours
Step-by-step explanation:
Givens
2/4 mile = 1/2 mile when 2/4 is reduced. 1/2 = 0.5 miles in decimal form.
1/10 = 0.1
0.5 miles 1 mile
======= = ======
0.1 hours x hours
Solution
Cross multiply
x* 0.5 = 0.1 * 1 Combine
0.5 x = 0.1 Divide by 0.5
x = 0.1/0.5
x = 0.2 hours.

What is an equation of the line that passes through the point (8,2) and is parallel to the line x+4y=28
Answer:
[tex]y =\frac{-1}{4}x + 4[/tex]
Step-by-step explanation:
Parallel lines have same slope
x + 4y = 28
4y = -x + 28
[tex]y=\frac{-1}{4}x+\frac{28}{4}\\\\y=\frac{-1}{4}x+7[/tex]
m = (-1/4) and line passes through (8 , 2)
Equation: y - y₁ = m(x - x₁)
[tex]y - 2 = \frac{-1}{4}(x - 8)\\\\y -2 = \frac{-1}{4}x - 8*\frac{-1}{4}\\\\y -2 = \frac{-1}{4}x + 2\\\\ y = \frac{-1}{4}x + 2 +2\\\\ y =\frac{-1}{4}x + 4[/tex]

a person walks 80 feet in 40 seconds. what equation represents this relationship. how many feet will the person walk in 10 seconds
Answer:
20 feet
Step-by-step explanation:
[tex]\frac{80 feet}{40 seconds}[/tex] = [tex]\frac{x feet}{10 seconds}[/tex]
Simplify [tex]\frac{80}{40}[/tex]
[tex]\frac{80}{40}[/tex] = [tex]\frac{2}{1}[/tex]
Every 1 second, a person will walk 2 feet.
[tex]\frac{x}{10}[/tex] = [tex]\frac{20}{10}[/tex]
X = 20 feet
Answer:
20 feet
Step-by-step explanation:
We can solve this two different ways:
The 1st and easiest way would be to first divide [tex]40/10[/tex] to get [tex]4[/tex], and then divide [tex]80/4[/tex] to get [tex]20[/tex].
This method works well in this situation because all the numbers are easily divisible, but in some situations this method may give you decimals which would make things more difficult.
In a situation like that, you would create a simple equation using this format: [tex]y=m(x)[/tex] in which [tex]y[/tex] represents the total number of feet walked, [tex]m[/tex] represents the number of seconds, and [tex]x[/tex] represents number of feet walked per minute.
You would start by finding out the number of feet walked per minute. You do this by plugging the information you know into the equation. We know that the person walks 80 feet in 40 seconds so the equation would look like this: [tex]80=40x[/tex]
To solve for [tex]x[/tex], you would then divide 40 on both sides to get [tex]2=x[/tex]
Now that we know that the person walks 2 feet every second, we can plug the information into a new equation to find out how far they go in 10 seconds. This equation will look like this: [tex]y=10(2)[/tex] and we can solve it to learn that [tex]y=20[/tex]. This means that the person will walk 20 feet in 10 seconds.
There are 23 animals in the field. Some are pigs and some are ducks. There are 80 legs in all. How many of each animal are in the field?
Answer:
Pigs = 17
Ducks = 6
Step-by-step explanation:
Let there be x pigs and y ducks in the field.
[tex]\implies x + y =23[/tex]
[tex]\implies y =23-x.....(1)[/tex]
Since, there are 80 legs in all.
Each pig has 4 legs and each duck has 2 legs. So, x pigs will have 4x legs and y ducks will have 2y legs.
Total legs = 4x + 2y
Total legs = 80 (Given)
[tex]\implies 4x + 2y =80....(2)[/tex]
From equations (1) & (2), we find:
[tex]\implies 4x + 2(23-x) =80[/tex]
[tex]\implies 4x + 46-2x =80[/tex]
[tex]\implies 2x =80-46[/tex]
[tex]\implies 2x =34[/tex]
[tex]\implies x =\frac{34}{2}[/tex]
[tex]\implies x =17[/tex]
[tex]\implies y =23-17[/tex]
[tex]\implies y =6[/tex]

Square root of 125 it’s between ___ and ___. It’s closer to ___.
Answer:
explantion IS the answer
Step-by-step explanation:
To estimate the square root of a number, we could start by relating the square to known perfect squares. 125 is between 11 and 12. It is probably closer to 11 since 125 is closer to 121 than to 144.

Answer:
so it's number 2
Step-by-step explanation:
just try it I'm sure it's right
Answer:
Second option: y = 5(x + 2)
Step-by-step explanation:
Equation that is already graphed: y = 5x - 10
Let's use the second option: y = 5(x + 2)
Since y = 5x - 10, we substitute 5x - 10 into the equation y = 5(x + 2)
The equation will look like this: 5x - 10 = 5(x + 2)
Now we solve: 5x - 10 = 5(x + 2)
5x - 10 = 5(x + 2)
Distribute
5x - 10 = 5x + 10
Rearrange variables to the left side of the equation
5x - 5x = 10 + 10
Apply the inverse property of addition
0 = 10 + 10
Add 10 and 10
0 = 20
Therefore, there is no solution
