Answer:

A: 8

Step-by-step explanation:

y = f(g(x)) = ( \sqrt{7x + b)}   \\ y= \sqrt{7x + b}  \\ at \: (4 \:  \: 6) \\  \\ i.e. \: plugging \: x = 4 \: and \: y = 6 \\  \\ 6  = \sqrt{7 \times 4 + b}    \\ 36 = 28 + b \\ b = 36 - 28 \\ b = 8 \\

you are starting your own buisness making candles. You spent $350 to get started and will charge each customer $85 for a case of
lara31 [8.8K]

Answer:

Option c.

Step-by-step explanation:

Missing options are attached below.

Given: Initial Investment is $350

           Selling price for each case of candles is $85.

Lets assume the number of case of candles be "x".

And let profit be "p".

The intitial investment will be negative as there is no immediate earning on it.

∴ Initial investment= -350

Profit increase with the number of customer buy the case of candles.

We know, Profit= selling\ price - Cost\ price

Here, cost is the amount spent in starting the business.

Now, p= 85x-350

Therefore, as per equation y intercept is -350 and slope is 85.

If divide the initial investment by selling price of each case of candles, we will get number of case of candle need to bought to get break even point of business, which is Cost Price - Selling Price= 0

∴ Number of cases of candles need to bought to get break even point= \frac{350}{85}= 4.11

Next, checking the graph, we find option c is correct as it is showing number of case of candles as 4.11 and profit as 0 (which is break even point).

Hence the answer is option c.

If a polynomial function f(x) has roots –8, 1, and 6i, what must also be a root of f(x)?
inna [77]
For any polynomial with a complex root, the imaginary part of the complex root always has positive and negaive component. Since one of the roots of this polynomial is 6i, then -6i must also be a root of the function.

What is the value of x?<br> 40°<br> (6x + 2)
Anvisha [2.4K]

Answer:

x = 8

Step-by-step explanation:

40 + 6x + 2 = 90   {Complementary angles}

Combine like terms

40+ 2 + 6x = 90

     42 +6x = 90         {Subtract 42 form both sides}

             6x = 90 - 42

             6x = 48       {divide both sides by 6}

        6x/6 = 48/6

             x = 8
