Which quadratic relation has a y-intercept of 8?
O y = 0.5(x + 2)(x + 4)
O y = 0.5 (x - 2)(+ 8)
O y = 0.5(x2 -2x - 16)
O y = 0.5 (x2 -2x + 16)

Answers

Answer:

y = 0.5 (x^2 -2x + 16) has a y-intercept of 8.

Step-by-step explanation:

The x-coordinate of every y-intercept is zero. To determine which of the four quadratics given here has a y-intercept of 8, we need only substitute 0 for x in each; if the result is 8, we've found the desired quadratic.

O y = 0.5(x + 2)(x + 4) becomes y = 0.5(2)(4) = 4 (reject this answer)

O y = 0.5 (x - 2)(x + 8) becomes y = 0.5(-2)(8) = -8 (reject)

O y = 0.5(x2 -2x - 16) becomes y = 0.5(-16) = -8 (reject)

O y = 0.5 (x2 -2x + 16) becomes y = 0.5(16) = 8 This is correct; that '8' represents the y-intercept (0, 8).

Read each of the statements that describe possible decompositions of the polygon in the image into two triangles that can represent the area of the polygon For each statement, determine if "Yes, it is a possible decomposition" or "No, Is it not a possible decomposition and explain your reasoning.

Statement A: the area of triangle GHL plus of triangle HIJ

Statement B: the area of triangle GHK plus the area triangle HIK

Statement C: the area of triangle GHK plus the area of triangle ILK

Statement D: the area of triangle GHK plus the area of triangle ILK

Answers

Need more information

The statements to determine the area of the polygon by division into triangles are evaluated as follows;

Statement A: the area of triangle GHL plus of triangle HIJ --No

Statement B: the area of triangle GHK plus the area triangle HIK --Yes

Statement C: the area of triangle GHK plus the area of triangle ILK. --No

Statement D: the area of triangle GHK plus the area of triangle ILK. --No

Polygons and Triangles

From the given description;

The polygon given can only be divided into two triangles if divided into triangles; GHK and HIK.

Hence, it follows that the area of triangle GHK plus the area triangle HIK is equivalent to the area of the given polygon.

corresponding sides of similar triangles are 4cm and 3metres .What is the enlargement factor 'k'?

Answers

Answer:

[tex]k = 75[/tex]

Step-by-step explanation:

Given

Corresponding sides: 4cm and 3m

Required

Determine the enlargement factor

This is calculated as:

[tex]k = \frac{New}{Old}[/tex]

So:

[tex]k = \frac{3m}{4cm}[/tex]

Convert to cm

[tex]k = \frac{3*100cm}{4cm}[/tex]

[tex]k = \frac{300cm}{4cm}[/tex]

[tex]k = \frac{300}{4}[/tex]

[tex]k = 75[/tex]

If if Spencer spent a total of $704.00 in the month of July, which is the best estimate for the amount of money he spent on clothing?

Answers

Answer:

Step-by-step explanation:

Given [Missing details]

Spencer's expenses

[tex]Clothing = 27\%[/tex]

[tex]Gasoline = 11\%[/tex]

[tex]Food = 44\%[/tex]

[tex]Entertainment = 18\%[/tex]

[tex]Total= \$704.00[/tex]

Required:

An estimate for the amount spent on clothing

To do this, simply multiply the clothing percentage by the total amount.

[tex]Clothing = 27\% * \$704.00[/tex]

[tex]Clothing = 0.27 * \$704.00[/tex]

[tex]Clothing = \$190.08[/tex]

A farmers field has the dimensions 2 and 3/4 by 1 and 1/3. He needs to find the area of the field

Answers

Answer:

3 2/3 units²

Step-by-step explanation:

Since the field is rectangular in nature;

Area of the field = Length * Width

Given

Length = 2 3/4

Width = 1 1/3

Area of the field = 2 3/4 * 1 1/3

Area of the field = 11/4 * 4/3

Area of the field = 4/4 * 11/3

Area of the field = 1 * 11/3

Area of the field = 11/3

Area of the field = 3 2/3

Hence the area of the field is 3 2/3 units²

Cellulon, a manufacturer of home insulation, wants to develop guidelines for builders and consumers on how the thickness of the insulation in the attic of a home and the outdoor temperature affect natural gas consumption. In the laboratory, it varied the insulation thickness and temperature. A few of the findings are:
Monthly Natural Gas Consumption (cubic feet), Thickness of Insulation (inches), Outdoor Temperature (ºF),
y x1 x2
30.3 6.0 32.0
25.2 12 40
30.5 8 49
On the basis of the sample results, the regression equation is:
yˆ y⁢^⁢ = 57.25 − 1.07x1 − 0.64x2

Answers

According to the regression equation, the predicted Monthly Natural Gas Consumption (ŷ) can be estimated by subtracting 1.07 times the Thickness of Insulation (x1) and 0.64 times the Outdoor Temperature (x2) from 57.25.

The regression equation provided is:

ŷ = 57.25 - 1.07x1 - 0.64x2

Where:

ŷ represents the predicted value of Monthly Natural Gas Consumption (cubic feet)

x1 represents the Thickness of Insulation (inches)

x2 represents the Outdoor Temperature (ºF)

Based on the regression equation, the coefficients indicate the relationship between the independent variables (Thickness of Insulation and Outdoor Temperature) and the dependent variable (Monthly Natural Gas Consumption).

The coefficient for x1 (Thickness of Insulation) is -1.07. This means that, holding the Outdoor Temperature constant, for every 1-inch increase in the Thickness of Insulation, the predicted Monthly Natural Gas Consumption is expected to decrease by 1.07 cubic feet.

The coefficient for x2 (Outdoor Temperature) is -0.64. This means that, holding the Thickness of Insulation constant, for every 1-degree Fahrenheit increase in the Outdoor Temperature, the predicted Monthly Natural Gas Consumption is expected to decrease by 0.64 cubic feet.

The constant term in the equation is 57.25. This represents the predicted Monthly Natural Gas Consumption when both the Thickness of Insulation and Outdoor Temperature are zero.
