Answer: 918 is the constant of variation.

Step-by-step explanation:

Since, In see saw the weight (w) of an object is inversely proportional to the distance (d) from the seesaw support.

That is w ∝ 1/d

or w = k/d

where k is the constant of variation.

Here, The weight of Levon, w = 153 lb

And, his distance from the see saw support, d = 6 ft

Therefore. 153 = k/6

⇒k= 153 × 6 = 918

The sum of 4 consecutive integers is 326. What is the second number in this sequence?

Fynjy0 [20]

Answer:

x + (x+1) + (x +2) + (x +3) = 326

4x + 6 = 326

4x = 320

x = 80

The second number would be 81

A painter earns $15 per hour. What is the minimum number of hours he must work to earn at least $200? Write an inequality to rep

IRISSAK [1]

So you know that he earns $15 per hour so we can write that as 15h, h = # of hours worked

We also know he has to earn AT LEAST $200, so putting all this together we form the inequality(=< means less than or equal to): 15h =< 200

so now we have to solve for h (number of hours worked):

15h =< 200

(divide both sides by 15)

h =< 13 1/3

So, the painter must work a minimum of 13 and 1/3 hours to earn at least $200.

one x-intercept for a parabola is at the point (2, 0). use the quadratic formula to find the other x-intercept for the parabola

omeli [17]

Answer:

Step-by-step explanation:

There are 3 ways to find the other x intercept.

1) Polynomial Long Division.

Divide x^2 - 3x + 2 by the binomial x - 2, because by the Factor Theorem if a is a root of a polynomial then x - a is a factor of said polynomial.

2) Just solving for x when y = 0, by using the quadratic formula.

$x^2 - 3x + 2 = 0\\x_{12} = \frac{3 \pm \sqrt{9 - 4(1)(2)}}{2} = \frac{3 \pm 1}{2} = 2, 1$ .

So the other x - intercept is at (1, 0)

3) Using Vietta's Theorem regarding the solutions of a quadratic

Namely, the sum of the solutions of a quadratic equation is equal to the quotient between the negative coefficient of the linear term divided by the coefficient of the quadratic term.

$x_1 + x_2 = \frac{-b}{a}$

And the product between the solutions of a quadratic equation is just the quotient between the constant term and the coefficient of the quadratic term.

$x_1 \cdot x_2 = \frac{c}{a}$

These relations between the solutions give us a brief idea of what the solutions should be like.
