ANSWER

y = 2x - 4

EXPLANATION

To find the equation of BC, we must find the slope and use the point B(4,4) with the slope to find the equation.

We know the slope of BC is perpendicular to the slope of AB.

But the slope of AB
= \frac{4 - 5}{4 - 2}

= - \frac{1}{2}

The slope of BC is the negative reciprocal of the slope of AB, which is
= - \frac{ 1 }{ - \frac{ 1}{2} }
= - 1 \times - \frac{2}{1} = 2

The equation in slope intercept form is given by,

y = mx + c

This implies that,

y = 2x + c

The point B(4,4) lies on this line so it must satisfy its equation,

4 = 2(4) + c

4 = 8 + c

c = 4 - 8 = - 4

The required equation is,

y = 2x - 4

The correct answer is A

Cans of regular Coke are labeled as containing 12 oz. Statistics students weighted the content of 5 randomly chosen cans, and fo
marishachu [46]

Answer: 0.0078

Step-by-step explanation:

We assume that cans of Coke are filled so that the actual amounts are normally distributed with a mean of 12.00 oz and a standard deviation of 0.12 oz.

As per given , we have

\mu=12.00\ oz  and \sigma=0.12\ oz

Sample size : n= 5

Let \overline{X} be the sample mean amount of coke in can.

Then, the  probability that a sample of 5 cans will have a mean amount of at least 12.13 oz will be :_

P(\overline{x}\geq12.13)=1-P(\overline{x}

=1-P(z

= 1-0.9922=0.0078  [By using z-table]

Hence, the required probability = 0.0078

Fantom [35]

Answer:

  3m = -3

Step-by-step explanation:

Subtract 2m from both sides of the equation:

  -6 = 6m

Divide both sides by 2:

  -3 = 3m

A soccer ball is kicked toward the goal. the height of the ball is modeled by the function h(t) = −16t2 48t, where t equals the
mamaluj [8]

It takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.

<h3>What is the axis of symmetry?</h3>

Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object.

1. The function  is a parabola of the form . The the formula for the axis of symmetry of a parabola is . We can infer from our function that a= -16 and b = 48, so lets replace those values in our formula:

x = \frac{-b}{2a}

x = \frac{(-48)}{-2(16)}

x = \frac{-48}{-32}

x = 1.5

We can conclude that to the left of the line of symmetry the ball is reaching its maximum height, and to the right of the line of symmetry the ball is falling.

2. Lets check how much time the ball takes to reach its maximum height and return to the ground. To do that we are going to set the height equal to zero:

-16t^{2} +48t = 0

-16t(t-3)=0

t = 0, (t-3) = 0

t = 0, t = 3

From our previous point we know that the ball reaches its maximum time at , which means that it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.

For the inequality y−x&gt;−x2−1, where is the graph shaded and is the curve solid or dotted?
vodomira [7]

The curve will be dotted and upper portion of the graph will be shaded.

<h3>Inequality expression</h3>

Inequality are expressions not separated by an equal sign Given the following inequality

y−x>−x2−1

Equate to zero

y > x^2 + x -1

Since the inequality sign in the given expression is a less than sign, hence the curve will be dotted.

Also, since the inequality sign is a "greater than", hence upper portion of the graph will be shaded.
