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

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

Answer:

The other part is 27 in. long

Step-by-step explanation:

1 ft is 12 in

2 ft are 24 in

4 ft are 48 in

48 in - 21 in = 27 in

Answer:

Part A

Green rope = 4 ft

As 1 ft = 12 in

Then 4 ft = 4 × 12 in = 48 in

Antonia cuts the green rope into 2 pieces.  One of the pieces is 21 in long.  To find the length of the unknown piece, subtract the length of the known piece from the total length:

length of unknown piece = 48 - 21

                                           = 27 in

Part B

Blue rope = 2 yd

1 yd = 36 in

Therefore, 2 yd = 2 × 36 = 72 in

Antonia wants to cut the rope into MORE than 3 pieces, and all the pieces need to be of equal length.  As the length of the rope is an even number of inches, Antonia could first cut the rope in half, so she would have 2 pieces each of 36 in in length.  Then she could cut both of those lengths in half, so she would have 4 pieces each of 18 in in length.

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.

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:

∠ 3 = 35°

Step-by-step explanation:

∠ 5 and ∠ 3 are alternate angles and congruent, thus

∠ 3 = ∠ 5 = 35°

Answer:

B is the answer

Step-by-step explanation:

looking at line CF,

it is a straight line thus being 180°

the < EOD is 90° < EOF is 55°

let < COD = t

therefore,

EOD + EOF + COD = 180

90 + 55 + t = 180

taking terms

t = 180 - (90 + 55)

t = 180 - 145

t = 35

COD = 35

EOD = 90

THUS, COE = COD + EOD

COE = 35 + 90

COE. = 125

[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]

Answer:

y = 2/3x + 4

Step-by-step explanation:

so we already know the y intercept is 4 so lets put that in the equation

y = mx + 4

now we use the equation y2 - y1 / x2 - x1 to find the slope

lets use the points (-6, 0) and (3, 6)

6 - 0 / 3 - (-6)

6 / 9

2/3

the equation is

y = 2/3x + 4

check:

lets use the point (6, 8)

substitute:

8 = 2/3(6) + 4 ?

8 = 4 +4?

8 = 8

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.

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]

(there is a notable difference of 80 on each row)

243+(80x4)=243+320=563

Answer:

563

Step-by-step explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding to the previous term in the sequence gives the next term. In other words, .

Formula;

L = a + (n - 1)*d

Givens

n = 70

a = 11

d = 8

Solution;

t = 11 + (70 - 1)*8

t = 11 + 69*8
