*IN YOUR OWN WORDS* Summarize the constant of proportionality.

Lilit [14]

Answer: Constant of proportionality is the constant value of the ratio between two proportional quantities. Two varying quantities are said to be in a relation of proportionality when, either their ratio or their product yields a constant.

Step-by-step explanation:

To find the constant of proportionality, we use the formula k=y/x. So we have k=20/500 = 0.04.

The equation representing this situation will look like y=kx. Substituting in our value of k that we found, we have the equation y=0.04x.

We can use our equation to find the answer to this problem.

Use the quadratic f(x)=x²+3x-4 and use any method to solve for the Zeros. Use the same function to solve for x when y is 6. F(x)

Katyanochek1 [597]

Answer:

a) $f(x) = (x+4)\cdot (x-3)$ , b) $x = -5$ or $x = 2$ , c) $x \approx 2.531$ or $x \approx -5.531$

Step-by-step explanation:

a) The function is solved by factorization:

$f(x) = (x+4)\cdot (x-3)$

b) The function has the following form:

$x^{2} + 3\cdot x - 4 = 6$

$x^{2} + 3\cdot x - 10 = 0$

The roots of the polynomial are found by factorization:

$(x+5)\cdot (x-2) = 0$

$x = -5$ or $x = 2$

c) The function has the following form:

$x^{2} + 3\cdot x - 4 = 10$

$x^{2} + 3\cdot x - 14 = 0$

The roots of the polynomial are determined by the General Formula for the Second-Order Polynomial:

$x_{1} = \frac{-3+\sqrt{3^{2}-4\cdot (1)\cdot (-14)}}{2\cdot (1)}$

$x_{1} \approx 2.531$

$x_{2} = \frac{-3-\sqrt{3^{2}-4\cdot (1)\cdot (-14)}}{2\cdot (1)}$

$x_{2} \approx -5.531$

The answer would be 3 because 15-4=11, each book is 3.5 pounds
3.5+3.5=7

An old billionaire is writing his will, and deciding how to distribute his nine estates among his three children. He wants to gi

Answer:

Step-by-step explanation:

6 2 1 How many ways does this produce and are they legitimate?

6 2 1
6 1 2
2 6 1
2 1 6
1 2 6
1 6 2

So any combination that you come up with, will produce 6 variations within those three choices. They are legitimate.

Lets see what you get with at most 5 estates to one person

5 3 1 Which will also give 6 variations. There are no other ways to make 5

4 3 2 Which will give 6 variations

I don't think there are any more possible choices.

Are the only 3 ways the estates can be split given the rules. Each choice leads to 6 other choices. The total is 18
