What is the relation between the variables in the equation y/x^2=10

2 answers:

8 0

The given expression is:

$\frac{y}{ x^{2} } =10$

which gives:

$y = 10x^{2}$

This implies that y and x^2 have an inverse relationship and "10" is the constant term in this expression.

The answer is C. y varies directly with x squared

I need to increase the number of customers by 20% daily, I talk to an average of 8 customers per hour during an 8 hour shift so

MA_775_DIABLO [31]

Before we figure out how many customers you will need to talk per day to reach your goal, let's calculate what is 20% of how many customers you normally talk to a day.

current no. = 8

goal = 8 + 20%

20% = 8 x 0.20

(a percent is really just a fraction with the percent number over 100)

20% = 1.60

goal = 8 + 1.60

goal = 9.60

However, there is no such thing as .60 of a person so we will have to round up. You will need to talk to 10 customers per day.

Solve the quadratic inequalities, by either graphing, or pure algebraic method:

BlackZzzverrR [31]

Answer:

less than/equal to -2

Or, greater than/equal to 2.5

Step-by-step explanation:

2x² - x - 10 ≥ 0

2x² - 5x + 4x - 10 ≥ 0

x(2x - 5) + 2(2x - 5) ≥ 0

(x + 2)(2x - 5) ≥ 0

Roots: -2, 5/2

x《 -2 or x》5/2

Select the correct answer from each drop-down menu. The graph represents the piecewise function.

kvasek [131]

The functions will be defined as y = x² if 0 ≤ x < 3, y = -x + 10 if 3 < x ≤ 6, and y = x + 2 if 6 ≤ x ≤ 10.

<h3>What is a function?</h3>

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The graph is given below.

The function can be defined as

The parabolic equation will be

f(x) = x²

The equation of the absolute function will be

f(x) = |x - 6| + 4

Then we have

$f(x) = \left\{\begin{matrix}y=x^2 & 0\leq x < 3 \\\\y=-x+10 & 3 < x\leq 6 \\\\y=x+2 & 6\leq x \leq 10 \\\end{matrix}\right.$
