Answer:

Step-by-step explanation:

I'm fairly certain you have an error in your equation as the curve you suggests opens upward so has no maximum profit. Profit becomes positive on completion of the 7th unit. (curve crosses x axis at (6.056, 0))

I will GUESS that the equation should read

P(x) = - 2x² + 120x – 800

Maximum will occur when the derivative is zero (zero slope)

P(x) = -2x² + 120x – 800

P'(x) = -4x + 120

    0 = -4x + 120

     x = 30

P(30) = -2(30)² + 120(30) – 800

P(30) = $1000

I NEED HELP NOW PLS ASAP
castortr0y [4]

Answer:

Step-by-step explanation:

hello,

I understand that there are only 4 cards  and then the player draw a card out of the 4 cards, replace it so the second draw is still out of the 4 cards

<u>How many ways can you draw two cards?</u>

as the first card is replaced, this is 4*4=16

so there is 16 possibles ways

hearts hearts

hearts clubs

hearts diamonds

hearts spades

clubs hearts

clubs clubs

clubs diamonds

clubs spades

diamonds hearts

diamonds clubs

diamonds diamonds

diamonds spades

spades hearts

spades clubs

spades diamonds

spades spades

<u>out of these 16 ways, how many have same colour for both cards?</u>

I assume that there are only two colours Red and Black, so we can have

only 8 ways so the first probability is 8/16 = 1/2

<u>out of these 16 ways, how many are red ace first and black ace?</u>

There are 4 ways so the probability is 4/16 = 1/4

hope this helps

Nate has an account that pays 2. 76% simple interest per year and wants to accumulate $3,090 in interest from it over the next 1
lana66690 [7]

We have given that,

interest rate = 2.76%

simple interest = 3,090

term = 15 years

<h3>What is the principle of simple interest?</h3>

Simple Interest = Principal * interest rate * term

3,090 = Principal * .0276 * 15\\3,090 = Principal * 0.414\\3,090 / 0.414  = Principal\\7,463.77 = Principal

Therefore,Nate should invest 7,463.77 to meet his goal.

Use the T-table below to determine 3 solutions to this equation: y = 2x
Jet001 [13]
The table is attached as a figure

The given equation is ⇒⇒⇒⇒ y = 2x
To solve this equation, we need to pick numbers from the table then this number will be substituted into the equation to find y
we need 3 solutions . so, we need to pick 3 numbers of x
From the table, let us choose x = 0
y = 2x
y = 2 * (0)
y = 0

From the table, let choose second value of x such as x = 1
y = 2 * (1)
y = 2

From the table, let choose third value of x such as x = -1
y = 2 * (-1)
y = -2

So, the picked three solutions are
y = 0  at   x = 0
y = -2  at  x = -1
y = 2 at  x = 1
