Answer:

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

The French Club's car wash is going to charge $10 per car, we can express this numerically as the following,

y = 10x

<u>Where:</u>

  • y is the total amount made
  • x is the number of cars

In this situation the <u>Independent Quantity</u> is x the number of cars. And the Dependent Quantities are both 10 and y , since 10 depends on x. While y depends on both 10 and x.

The Domain in this situation is the amount of cars (x), while the Range is the total amount (y). Since we cannot have a negative amount of cars the Domain and Range would be the following.

Domain: [0, +∞) ......allowing only whole numbers

Range: [0, +∞) ..... in intervals of 10

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

The initial size of the population is 300. After 1 day the population has grown to 800. Estimate the population after 6 days. (R
Cloud [144]

Solution :

Given initial population = 300

Final population after 1 day = 800

Number of days = 6

∴ $\frac{dP}{dt} =kt^{1/2} $

P(0) = 300    P(1) = 300

We need to find P(8).

$dP = kt^{1/2} dt$

$ \int 1 dP = \int kt^{1/2} dt$

$P(t) = k \left(\frac{t^{3/2}}{3/2}\right)+c$

$P(t)= \frac{2k}{3}t^{3/2} + c$

When P(0) = 300

$300 = \frac{2k}{3} (0)^{3/2} + c$

∴ c = 300

∴ $P(t)= \frac{2k}{3}t^{3/2} + 300$

When P(1) = 800

$800 = \frac{2k}{3} (1)^{3/2} + 300$

$500 = \frac{2k}{3}$

∴ k = 750

$P(t)= 500t^{3/2} + 300$

So, P(8) is

$P(t)= 500(8)^{3/2} + 300$

        = 11,614

So the population becomes 11,614 after 8 days.

How do I solve this? Thank you.
MariettaO [177]

Answer:

Heyya little student!

Sin means \frac{opposite }{hypotenuse}

5 is the hypotenuse (its opposite to 90 degrees )

So, sin β would be:-

the side opposite to the angle β divided by the hypotenuse of the triangle.

The side opposite to β is 4

and as I said earlier, the hypotenuse is 5

<h2>So, sin β would be:-</h2><h2>\frac{4}{5}</h2>

I hope it helped you!

Keep learning

and never stop smiling

You Are Awesome!
