PLEASE ANSWER + BRAINLIEST!! Use the quadratic formula to solve. 3x^2 = 5x

Mathematics
1 answer:
ra1l [238]3 years ago
6 0
The quadratic formula is:

\frac{-b \pm  \sqrt{b^2-4ac} }{2a}

To solve the equation using the quadratic formula, we must put it in ax^2+bx+c form.

3x^2 - 5x + 0 = 0

Now plug a, b, and c into the formula and solve:

\frac{5 \pm  \sqrt{25 - 4(3)(0)} }{6}

Simplify:

\frac{5 \pm  \sqrt{25-0} }{6}

\frac{5 \pm 5}{6}

x = \frac{10}{6} or 0

Reduced, the answer is:

x = 5/3 or 0

What is the average rate of change for the function f(x)=x^2+4 for the domain of -2 to 4
Neko [114]

Answer:

  2

Step-by-step explanation:

For a quadratic function the average rate of change on an interval is the rate of change at the midpoint of the interval. The rate of change of a function is given by its derivative.

The derivative of f(x) = x^2 is f'(x) = 2x. The midpoint of the interval is (4+(-2))/2 = 1. Then the average rate of change is ...

  f'(1) = 2(1) = 2

The average rate of change of f(x) on [-2, 4] is 2.

__

<em>Alternate solution</em>

The average rate of change is the slope of the line between the end points of the interval:

  m = (y2 -y1)/(x2 -x1)

  m = (f(4) -f(-2))/(4 -(-2)) = (20 -8)/(6) = 2

The average rate of change on [-2, 4] is 2.

_____

The attached graph shows the points on the curve and a line with slope 2 between them. It also shows the various slope calculations.

Gary's contract says he must work at least 20 hours per week. Gary is paid $15.50 per hour. Gary is also paid $50 per week. Gary
Rasek [7]

Answer: Gary needs to work more than 25hours for the week to earn above $400.

Step-by-step explanation:

For Gary to be paid $50 per week means he worked $50/ $15.50= 3.23 hours for the week.

To make over $400 this week he needs to work for

400/15.50 = 25.81 hours and more for the week to earn above $400
