Answer:

y+9=-1(x-4)

Step-by-step explanation:

Point Slope Form is:

$y-y_1=m(x-x_1)$

When:

'm' is the slope.

$(x_1,y_1)$ is the coordinate.

We are given the slope of -1 and the coordinate of (4,-9).

So:

$m=-1\\x_1=4\\y_1=-9$

Using the information and replacing the values we get:

$y+9=-1(x-4)$

So, the line equation in point slope form should be: y+9=-1(x-4)

James has a piece of constrution paper with area of 65 1/4 inches . It is 9 2/3 inches long. What is the width of the piece of c

MrMuchimi

Answer:

The width of the piece of construction paper is 6.75 inches.

Step-by-step explanation:

The area of the paper = $65\frac{1}{4} = 65.25$ sq inches

The length of the paper = $9\frac{2}{3} = 9.66$ in

Let the width of the paper = w inches

Now, AREA OF THE PAPER = LENGTH x WIDTH

or, 65.25 sq. inches = 9. 66 in x w in

⇒ 65.25 = 9.66 x w

or, $w = \frac{65.25}{9.66} \implies w = 6.75$

or, w = 6. 75 inches

Hence, the width of the piece of construction paper is 6.75 inches.

Suppose a baby food company has determined that its total revenue R for its food is given by R = − x 3 + 39 x 2 + 945 x where R

Paraphin [41]

Answer:

35,000 units

Step-by-step explanation:

Total revenue is:

$R = -x^3+39x^2+945x$

The maximum revenue is attained at the production level for which the derivate of the revenue function is zero:

$R = -x^3+39x^2+945x\\R'=0=-3x^2+78x+945\\x=\frac{-b\pm\sqrt{78^2-(4*(-3)*945)} }{-6}\\x_1=35\\x_2=-9$

Since production cannot be negative, revenue will be at a maximum when x = 35, or when the production level is 35,000 units.

Which distribution has the greatest spread

Sauron [17]

For solving this question we will use the relationship between the range of data and the spread of data. The relationship is that "Higher the Range of the Data, Higher is the Spread and lower the range of the data then lower is the spread".

So, keeping in mind this definition let us proceed and check each option and measure their range.

We know that Range is measured as

Range=(Highest Value of the Data)-(Lowest Value of the Data)

a. 13.7-3.1=10.6

b. 423.6-1.3=422.3

c. 38.4-7.2=31.2

d. 231.4-5.5=225.9

As we can see Option b. has the largest range and as range is a measure of spread then option b is the distribution which has the largest spread.
