Answer 2

Area of Shaded

Find the area of the shaded area shown.

Solution:

A = s²A = 32cmA = 32cm x 32cmA = 1024A = 32/4/2A = 32 ÷ 2A = 8A = 8 ÷ 2 A = 4

So in the inscribed circle there are 16.

A = 16 radius ²A = 16 x 4r²A = 4 x 4A = 16A = 16π x 16A = 256πA = 256 x 3.14A = 803.84A = 1024cm - 803.84A = 220.16cm²

The graph of the function y = 2|x| is a vertical stretch by a factor of 2 of the parent function y = |x|.

How to identify the transformation?

The functions for this problem are defined as follows:

Parent function: y = |x|.Transformed function: y = 2|x|.

When a function is multiplied by 2, we have that it is vertically stretched by a factor of 2.

Hence the graph of the function y = 2|x| is a vertical stretch by a factor of 2 of the parent function y = |x|.

Part (a)

Answer: x = -8

------------------

Work Shown:

2(x-1) = 3(x+2)

2x-2 = 3x+6 .... distribute

2x = 3x+6+2 .... adding 2 to both sides

2x = 3x+8

2x-3x = 8 .... subtracting 3x from both sides

-x = 8

x = -8 ..... multiply both sides by -1

===========================================================

Part (b)

Answer: x = 5/11

------------------

Work Shown:

-4(2x-2) = 3(x+1)

-8x+8 = 3x+3 ..... distribute

-8x = 3x+3-8 .... subtract 8 from both sides

-8x = 3x-5

-8x-3x = -5 ... subtract 3x from both sides

-11x = -5

x = -5/(-11) .... divide both sides by -11

x = 5/11

In decimal form, this is approximately equal to 5/11 = 0.4545

A family would like to build a linear regression equation to predict the amount of grain harvested per acre of land on their farm. They subdivide their land into several smaller plots of land for testing and would like to select an explanatory variable they can control. Which of the following is an appropriate explanatory variable that the family could use to create a linear regression equation?

a. The total amount of rainfall recorded at their farm ).
b. The type of crop planted in the plot the previous year.
c. The average daily temperature at their farm.
d. The variety of grain planted in the plot.
e. The amount of fertilizer applied to each plot of land.

Answers

Answer:

The correct option is;

The amount of fertilizer applied to each plot of land

Step-by-step explanation:

The value which the family would like to predict = The amount of grain harvested per acre of land on their farm

The methodology to be used for the prediction = Linear regression equation

The general form of a linear regression equation is Y = a + b·X

Where;

X = The independent or explanatory variable

Y = The dependent variable

b = The gradient or slope which is the rate of change

a = The y-intercept, the initial value of the dependent variable at the start of observation when the explanatory variable is 0

Therefore, given that the family would like to predict the amount of grain produced per acre, we have;

The variable which is whose value depends on other variable is the variable to be predicted and it is the same as the dependent variable

Therefore, the dependent variable is to be predicted, which gives;

The amount of grain produced per acre which is the dependent variable is to be predicted

Hence, Y = The amount of grain produced per acre

The explanatory variable or the independent variable is the variable which determines the value and in which the dependent variable depends as such it can be used to explain the values of the amount of grain growing per acre, therefore, we have;

The explanatory variable can be the amount of fertilizer applied to each plot of land

Therefore;

X = The amount of fertilizer applied to each plot of land

Therefore, we have;

The amount of grain produced per acre = The initial growth of grain per acre + (Rate of change of grains produced per unit of fertilizer added) × (The amount of fertilizer applied to each plot of land).

The explanatory variable refers to the independent variable in an experiment which is used to tweak the value of the measured variable. An appropriate explanatory variable would be the amount of fertilizer applied to each plot of land

Explanatory would be one which has a reasonable degree of correlation or relationship with the measured variable.

Since, we'll like to measure the output on each plot using the amount of grain harvested, then a factor which closely affects the level of crop yield should be selected.

The amount of Rainfall and temperature are close factors, however, they cannot be controlled.

The most appropriate and highly correlated explanatory variable would be the amount of fertilizer applied to each plot of land.

Therefore, the amount of fertilizer is a good factor to measure the yield or amount of grain harvested on each plot.

It says mr fuller wants to put fence around his rectangular yard. The length is 75 and the width is 55.

Answers

Answer:

Step-by-step explanation:

You have omitted relevant parts of the question. What is the question? Are you looking for the area of the yard? The amount of fencing needed?

What units are used? (Feet, yards, meters, etc.)

area of yard = 75×55 = 4125 units²

amount of fencing needed = perimeter of rectangle = 2(75+55) = 260 units.

The total length of the fencing is the perimeter of the rectangular yard which is P = 260 feet

What is the Perimeter of a Rectangle?

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P = 2 ( Length + Width )

Given data ,

The width of the rectangular yard W = 55 feet

The length of the rectangular yard L = 75 feet

Let the perimeter of the rectangular yard be = P

And , the required fencing = Perimeter of rectangular yard

Perimeter of rectangular yard P = 2 ( L + W )

Substituting the values in the equation , we get;

Perimeter of rectangular yard P = 2 ( 55 + 75 )

Perimeter of rectangular yard P = 2 ( 130 )

Perimeter of rectangular yard P = 260 feet

Therefore , the value of P is 260 feet

Hence , the perimeter of yard is 260 feet

Part of the graph of the function f(x) = (x – 1)(x + 7) is shown below.

Which statements about the function are true? Select three options.

The vertex of the function is at (–4,–15).
The vertex of the function is at (–3,–16).
The graph is increasing on the interval x > –3.
The graph is positive only on the intervals where x < –7 and where
x > 1.
The graph is negative on the interval x < –4.

Answers

Answer:

The vertex of the function is at (–3,–16)

The graph is increasing on the interval x > –3

The graph is positive only on the intervals where x < –7 and where

x > 1.

Step-by-step explanation:

The graph of $f(x)=(x-1)(x+7)$ has clear zeroes at $x=1$ and $x=-7$, showing that $f(x) > 0$ when $x < -7$ and $x > 1$. To determine where the vertex is, we can complete the square:

$f(x)=(x-1)(x+7)\\y=x^2+6x-7\\y+16=x^2+6x-7+16\\y+16=x^2+6x+9\\y+16=(x+3)^2\\y=(x+3)^2-16$

So, we can see the vertex is (-3,-16), meaning that where $x > -3$, the function will be increasing on that interval

Answer:

x = 27 , ∠ EAF = 27°

Step-by-step explanation:

∠ GAF = 90° , then

∠ GAC + ∠ CAF = ∠ GAF , that is

x + 63 = 90 ( subtract 63 from both sides )

x = 27

∠ DAE = 90°

since CD is a straight angle of 180° , then

∠ CAE = 90° , so

∠ CAF + ∠ EAF = ∠ CAE , that is

63° + ∠ EAF = 90° ( subtract 63° from both sides )

∠ EAF = 27°

Answers

Answer:

$\boxed{\text{The slope is -8.}}$

Step-by-step explanation:

To find the slope of the line, you have to use a slope formula.

Slope formula:

$\Longrightarrow:\sf{\dfrac{y_2-y_1}{x_2-x_1} }$

⇒ y2=(-15)

⇒ y1=1

⇒ x2=1

⇒ x1=(-1)

Rewrite the whole problem down.

$\Longrightarrow: \sf{\dfrac{-15-1}{1-\left(-1\right)}=\dfrac{-16}{2}=\boxed{\sf{-8}}$

So, the slope is -8, which is our answer.
