Answer: 896

Step-by-step explanation:

Let's use a rule of three here.

\frac{576}{x}=\frac{18}{28}

Solve for x;

x=\frac{576*28}{18}

x=896

Anni [7]

Answer:

(x+1)(x²-4x+1)

Step-by-step explanation:

f(x) = x³-3x²-3x+1

     = (x³+1) - 3x (x+1)

     = (x+1)(x²-x+1) - 3x(x+1)

     = (x+1)(x²-x+1-3x)

     = <u>(x+1)(x²-4x+1)</u>

<u />

** (x+1)(x²-4x+1) = (x+1)((x-2)² - 3)

                        = (x+1)((x-2)² - (√3)²)

                        = (x+1)(x-2-√3)(x-2+√3)

a beekeeper estimates that his bee population will triple each year. Currently he has 150 bees. Write a function to represent th
Soloha48 [4]

Answer:

Exponential functions!

Step-by-step explanation:

I think what you are dealing with is an exponential function!

So, to solve this, we need to first understand the main form of an exponential function:

f(x)=a*b^{x}

Where a is the number we start off with, and b is the constant thing(forgot what it was called).

Now, 150 is our starting number, so it is a, and b is our constant at which the initial term is multiplied, which is 3!

Also, defining variables:

Let f(x)= # of Bees

Let x= # of years

Thus, here is our equation:

f(x)=150*3^{x}

So, that's it!

Now, some of my answers have been recently deleted because they violated community guidelines for recommending something that shall not be named, so if you do really need help on the subject, look online! It is the largest source of information humanity has created! (also I cannot explain Exponential Functions in a single paragraph)

Please help I’ll mark you as branlst
wariber [46]

Answer:

6

Step-by-step explanation:

Since the degree of the angle is 45, we know that the triangle is isosceles. That means that the sides of the triangle, not including the hypotenuse, has a length of 3√2.

Using the Pythagorean theorem, which is a^2 + b^2 = c^2, we have (3√2)^2 + (3√2)^2 = c^2.

Note: c is the hypotenuse of the triangle.

18 + 18 = c^2

= 36 = c^2

Therefore, c = 6.
