Answer:
The graph has no y intercepts
Step-by-step explanation:
Given
[tex]y = \frac{2}{x} - 1[/tex]
Required
True about the graph
The graph has no y intercepts because this would mean:
[tex]y = \frac{2}{0}-1[/tex]
2/0 is undefined. Hence, the graph has no y intercept.
Which is the graph of y=[x]-2?
Answer:
The function y = ⌊x⌋ is called the "greatest integer value" function.
it works as follows: the input is any number x, the output is the greatest
integer smaller or equal to x.
For example:
⌊0.1⌋=0
⌊0.26⌋=0
⌊0.4678⌋=0
⌊0.8989⌋=0
⌊0.999⌋=0
⌊1⌋=0
⌊1.0001⌋=1
so, the value of ⌊x⌋, for the entire interval (0, 1] is 0.
Similarly,
the value of ⌊x⌋, for the entire interval (1, 2] is 1. and so on,
thus the graph of y = ⌊x⌋ is as shown in picture 1
the graph of y = ⌊x⌋ – 2 is the graph of y = ⌊x⌋ shifted 2 units down.
check picture 2.
what's a circumference of a circle with a diameter of 100 inches
Answer:
The circumference will be equal to 314 inches if we take 3.14 as pi's value.
Step-by-step explanation:
In order to find the circumference, we need to know the following...
circumference = diameter x π
π is a math constant pi.
So we just substitute the values and get that...
circumference = 100 x π
circumference = 100π
circumference ≅ 314 inches
uppose paired data are collected consisting of, for each person, their weight in pounds and the number of calories burned in 30 minutes of walking on a treadmill at 3.5 mph. How would the value of the correlation coefficient, r, change if all of the weights were converted to kilograms
Answer:
Has no effect on the correlation
Step-by-step explanation:
The correlation coefficient measures the strength of the relationship between two variables and it has no unit of measurement. All that correlation Coefficient does is to observe whether increase in variable x increases as variety able y increases and vice versa and how closely the values in each if the two variables are related. This is to emphasize that, the correlation Coefficient is independent of the unit of measurement of the two variables in question.
Hence, converting all weights to kilograms has no effect on the correlation Coefficient
What is the value of x?
Answer:
45 degree
Step-by-step explanation:
3x - 9 + 24 + 30 = 180 degree (being sum of interior angles of a triangle)
3x + 45 = 180
3x = 180 - 45
x = 135/3
x = 45 degree
Answer:45 độ
Step-by-step explanation:
3x - 9 + 24 + 30 = 180 độ (là tổng 3 góc của tam giác)
3x + 45 = 180
3x = 180 - 45
x = 135/3
x = 45 độ

The city of Atlanta wants to paint a cylindrical-shaped water tank. The height of the tank is 88 feet and the radius is 25 feet. How much water will this tank hold
Answer:
The tank can hold water 172,857.14 cubic feet
Step-by-step explanation:
Given that the shape is cylindrical, the amount of water it can hold may be determined using the formula for the volume of a cylinder.
The volume V of a cylinder whose base radius r and height is h is given as
V = Pir^2h where Pi is 22/7
Given that the height of the tank is 88 feet and the radius is 25 feet, then the volume V
= 22/7 * 25^2 *88
= 172,857.14 cubic feet

9514 1404 393
Answer:
9°, 9°, 162°
Step-by-step explanation:
Let x represent the measure of the first angle. Then the sum of all of the angles in the triangle is ...
x + x + 9(x+x) = 180°
20x = 180° . . . . . . . . . . collect terms
x = 180°/20 = 9° . . . . . divide by 20

Company is preparing budgets for the quarter ending June 30, 2019.
Budgeted sales in units for the next five months are:
April 20,000
May 50,000
June 30,000
July 25,000
Required:
a. Prepare Sales budget for April, May & June assuming selling price per unit is 15.
b. Prepare production budget for April, May & June if the company wishes ending inventory as 10 % of next month sales units.
Answer:
Results are below.
Step-by-step explanation:
First, we need to determine the sales budget for April, May, and June:
Sales budget April:
Number of units sold= 20,000
Sales revenue= 20,000*15= $300,000
Sales budget May:
Number of units sold= 50,000
Sales revenue= 50,000*15= $750,000
Sales budget June:
Number of units sold= 30,000
Sales revenue= 30,000*15= $450,000
Now, the production budget using the following formula:
Production= sales + desired ending inventory - beginning inventory
Production budget April:
Sales= 20,000
Desired ending inventory= 50,000*0.1= 5,000
Beginning inventory= 0 (assuming no beginning inventory)
Production= 25,000
Production budget May:
Sales= 50,000
Desired ending inventory= 30,000*0.1= 3,000
Beginning inventory= (5,000)
Production= 48,000
Production budget June:
Sales= 30,000
Desired ending inventory= 25,000*0.1= 2,500
Beginning inventory= (3,000)
Production= 29,500

If paper products accounted for 33% of the total MSW recycled in 2010 and about 7m3 of landfill space is saved for each metric ton of paper products recycled, calculate how much landfill space was saved by recycling paper products in 2010 in the United States.
Answer:
Volume of landfill space saved by recycling paper products in 2010 in the United States = 175.56 million m³ of land space
Note: The Table in the attachment below Shows The Total MSW (in Metric Tons) And Percent MSW Recycled Over Time In The United States.
Step-by-step explanation:
Step 1: Determining the amount in metric tons of paper products recycled
In the year 2010, a total of 76 million metric tons of MSW was recycled.
Recycling of paper products accounted for 33% of the total MSW recycled in 2010.
The amount of paper products recycled in millions of metric ton = 0.33 × 76 million = 25.08 million metric tons of paper products.
Step 2: Determining the volume of landfill space saved in 2010 by recycling paper products
7m³ of landfill space is saved for each metric ton of paper products.
Volume of landfill space saved by recycling paper products in 2010 in the United States = total amount of paper products recycled × 7 m³/metric ton
Volume of landfill space saved = 25.08 million metric tons × 7 m³/metric ton
Volume of landfill space saved = 175.56 million m³ of land space
Therefore, volume of landfill space saved by recycling paper products in 2010 in the United States = 175.56 million m³ of land space
Using proportions, it is found that about 21 cubic metres of landfill space was saved by recycling paper products in 2010 in the United States.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, 33% of the total amount is equivalent to 7 cubic metres, hence:
0.33t = 7
t = 7/0.33
t = 21
21 cubic metres of landfill space was saved by recycling paper products in 2010 in the United States.

Gregory knows that ABC is reflected onto A'B'C. Which statement about the figures is true? Olf Gregory draws the segment with endpoints A and A', then the midpoint will lie on the line of reflection O If Gregory draws the segment with endpoints B and C', then the midpoint will be on the line of reflection O Points A and B are equidistant from the line of reflection O AB will be perpendicular to the line of reflection
The true statement about the reflection is (a) If Gregory draws the segment with endpoints A and A’, then the midpoint will lie on the line of reflection.
When a shape is reflected, it must be reflected across a line (called the line of reflection)
The line of reflection is always located at a point equidistant to the image and the pre-image of the shape that is being reflected
Hence, the true statement is (a) If Gregory draws the segment with endpoints A and A’, then the midpoint will lie on the line of reflection.

Answer:
the awnser is 124 YW:)
Step-by-step explanation:
62x2=124
Answer:
124 / C
Step-by-step explanation:
The angles of a triangle add up to 180 degrees. We know that angle k is 62, angle J is 90, that adds to 152. 180-152 gives us the third angle of the triangle as 28. Assuming that the two triangles are similar, the angle opposite of the 28 degree is also 28 degrees. The angles on the line should also add up to 180 degrees. So 180 - 28 - 28 = 124.
