Answer:

4 < x < 15.

Step-by-step explanation:

Solve -2x^2 + 38x -120 = 0 This gives x = 4 and x = 15. So the company makes a profit when the range of x is greater than 4 and less than 15. The graph of function is a flipped U which pass through x axis at 4 and x = 15. Above the x-axis is the area of profit.

Answer:

621,810 square yards

1,865,430 square feet

128.47 acres

353.30 square miles

Step-by-step explanation:

Since Cindy owns a plot of land measuring 630 yards wide by 987 yards long, to determine what is the area of the land in square yards, square feet, acres and square miles, the following calculations must be performed:

1 yard = 3 feet

1 square yard = 0.000206612 acres

1 yard = 0.000568182 miles

Square yards: 630 x 987 = 621,810 square yards

Square feet: 621,810 x 3 = 1,865,430 square feet

Acres: 621,810 x 0.000206612 = 128.47 acres

Square miles: 621.810 x 0.000568182 = 353.30 square miles

Step-by-step explanation:

4 x 3 + 6

12 + 6

= 18

or

4 x (3+6)

4 x 9

= 36

depends whether the 3+6 is in brackets :)

Answer:

if x = 4

then,

4 (3 + 6)

12 + 24

= 36

Depends whether they are in brackets but usually i would consider it in this problem.

Without the brackets would be:

4 x 3 + 6

12 + 6 = 18

Language Arts 6 B  Unit 7 Lesson 13

Students would want to include sensory language which describes in the solution part that focuses on writing about their favorite food.

Sensory Language is a word or words used to evoke mental imagery and help the reader visualize the tale or poetry. Imagery is a literary method that appeals to the reader's senses, whereas Sensory Language is a writing style and how writers utilize words to generate images for the readers.

When writing about their favorite food, a student might want to include sensory language that focuses on how the food looks, smells, tastes, feels, and sounds. This can help to paint a vivid picture for the reader and make the experience of reading about the food more immersive.

For example, if the student's favorite food is pizza, they might describe the golden, crispy crust; the savory, spicy tomato sauce; the gooey, melted cheese; the spicy sausage and bell peppers; and the satisfying crunch that it makes when they take a bite. They might also describe the way the warm, comforting aroma of the pizza fills the room as it cooks, or the way the different textures and flavors come together in each bite to create a satisfying and delicious meal. By using descriptive language that focuses on the senses, the student can help the reader to better understand and share in their love of the food.

Answer:

Step-by-step explanation:

The sales will double on the 6th day of the month

The equation sales for last month = 4(day of the month) + 16

let

x = day of the month

The day of the month could be 1, 2, 3, 4, 5, 6, 7, 8...…31. The numbers represents the first, second, third ,...… thirty first day.

Sales = 4x + 16

From the equation, on the first day his sales  will be :

sales = 4(1) + 16 = 20 units

The double of 20 units is 40 units. Therefore, the day of the month which the sales will double can be calculated below

40 = 4x + 16

40 - 16 = 4x

4x = 24

x = 24 / 4

x = 6

it will double on the 6th day.

Answer:

cos 2x = (√7) / 4

Step-by-step explanation:

sin x - cos x = 1/2

(sin x - cos x)² = (1/2)²

sin²x - 2 sin x cos x + cos² x = 1/4

1 - 2 sinx cosx = 1/4

2 sinx cosx = 3/4

sin 2x = 2 sinx cosx = 3/4

sin² 2x = 9/16

cos² 2x = 1 - sin² 2x = 1 - 9/16 = 7/16

cos 2x = (√7) / 4

Answer:

  9) 39.7°

  10) insufficient information

  11) 20.0 in

  12) 19.0 m

Step-by-step explanation:

These Law of Sines problems are all worked the same way. For sides a, b, and opposite angles A, B, the relevant relationship is ...

  a/sin(A) = b/sin(B)

This gives rise to formulas for angle and side:

  A = arcsin(a/b·sin(B))

  a = b·sin(A)/sin(B)

If the longest given side is not opposite the largest given angle, there may be two solutions.

_____

9) B = arcsin(8/12.5·sin(87°)) = 39.7°

10) missing a side or angle; insufficient information

11) f = (5 in)·sin(70.4°)/sin(13.6°) = 20.0 in

12) p = (22 m)·sin(59°)/sin(180°-59°-24°) = 19.0 m

Step-by-step explanation:

to make a graph, when you have the equations, as you do,  just make up a table of some x coordinates,  you get to choose which ever ones you want so pick some easy ones,   like - 2,-1 , 0, 1, 2  .. then put each of those numbers into your equations as the x ... one at a time, ofc,   and see what you get out for y.  then you have the y coordinate of your table  

when you have your table then you can plot each of the points,  if you use the Demos  web site graphing tool you can make the graph on your computer , or use a graph paper.

Answer:

0.9772 = 97.72% probability that a randomly selected firm will earn more than Arc did last year

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Suppose the mean income of firms in the same industry as Arc for a year is 90 million dollars with a standard deviation of 7 million dollars.

This means that [tex]\mu = 90, \sigma = 7[/tex]

What is the probability that a randomly selected firm will earn more than Arc did last year?

Arc earned 76 million, so this is 1 subtracted by the pvalue of Z when X = 76.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{76 - 90}{7}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

1 - 0.0228 = 0.9772

0.9772 = 97.72% probability that a randomly selected firm will earn more than Arc did last year
