Answer:

A) the fraction of the week that Jamaar spent in this garden.

Answer: Y = 4x + 2

(It would be either the third or fourth choice since they are the same, one of them must be mistaken)

Step-by-step explanation:

Given information

(x₁, y₁) = (1, 6)

(x₂, y₂) = (0, 2)

Find the slope through the formula

[tex]Slope~=~\frac{y_2~-~y_1}{x_2~-~x_1}[/tex]

[tex]\Large Slope~=~\frac{2~-~6}{0~-~1}[/tex]

[tex]\Large Slope~=~\frac{-4}{-1}[/tex]

[tex]\Large Slope~=~4[/tex]

Substitute values into the linear form

Equation: y = mx + b

Point (0, 2)

y = mx + b

(2) = (4) (0) + b

2 = 0 + b

b = 2 - 0

b = 2

Therefore, the equation is [tex]\Large\boxed{y=4x+2}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

Answer:

y = 4x+2

Step-by-step explanation:

The first step is to find the slope

m = ( y2-y1)/(x2-x1)

m = ( 2-6)/(0-1)

    = -4/-1

   = 4

The slope intercept form of the equation is

y = mx+b  where m is the slope and b is the y intercept

y = 4x+b

The y intercept is where x is equal to 0

The y intercept is 2

y = 4x+2

Answer:

x = 99°

y = 91°

Step-by-step explanation:

For Cyclic quadrilateral, the sum of the opposite angles = 180°

Let's find x :-

x + 81° = 180°

x = 180 - 81

x = 99°

Let's find y :-

y + 89° = 180°

y = 180 - 89

y = 91°

Answer:

Point Z

Step-by-step explanation:

Since the scale is one, first you go 0.5 to the left (-0.5 X) then you go 0.75 up (0.75 Y) then you have your answer.

Answer: x < -2

Step-by-step explanation:

[tex]\frac{1}{2} x-7 < -8[/tex]

First add 7 to both sides

[tex]\frac{1}{2} x-7 +7 < -8+7[/tex]

[tex]\frac{1}{2} x < -1[/tex]

Now multiply by 2 to cancel out 1/2 and leave you with x

[tex]2*\frac{1}{2} x < -1(2)[/tex]

[tex]x < -2[/tex]

Part A

[tex]4x^2 -7x-15=0\\\\(4x+5)(x-3)=0\\\\x=-\frac{5}{4}, 3[/tex]

So, the x-intercepts are [tex]\boxed{\left(-\frac{5}{4}, 0 \right), (3,0)}[/tex]

Part B

The vertex will be a minimum because the coefficient of [tex]x^2[/tex] is positive.

The x-coordinate of the vertex is [tex]x=-\frac{-7}{2(4)}=\frac{7}{8}[/tex]

Substituting this back into the function, we get [tex]f\left(\frac{7}{8} \right)=4\left(\frac{7}{8} \right)^2 -7\left(\frac{7}{8} \right)^2 -15=-\frac{289}{16}[/tex]

So, the coordinates of the vertex are [tex]\boxed{\left(\frac{7}{8}, -\frac{289}{16} \right)}[/tex]

Part C

Plot the vertex and the x-intercepts and draw a parabola that passes through these three points.

The graph is shown in the attached image.

From the attached figure, we have the following parameters:

The area of region 1 is calculated using:

Region 1 = Area of square - Area of circle B

This is calculated as

Region 1 = L^2 - π(d/2)^2

So, we have:

Region 1 = 24^2 - 3.14 * (20/2)^2

Evaluate the quotient

Region 1 = 24^2 - 3.14 * 10^2

Evaluate the exponent

Region 1 = 576 - 3.14 * 100

Evaluate the product

Region 1 = 576 - 314

Evaluate the difference

Region 1 = 262

The cost per square inch of this region is $0.10.

So, we have:

Total cost of region 1 = 262 * $0.10

Total cost of region 1 = $26.10

The area of region 2 is calculated using:

Region 2 = Area of circle B - Area of circle A

This is calculated as

Region 2 = π(D/2)^2 - π(d/2)^2

So, we have:

Region 2 = 3.14 * (20/2)^2 - 3.14 * (18/2)^2

Evaluate the quotient

Region 2 = 3.14 * 10^2 - 3.14 * 9^2

Evaluate the exponent

Region 2 = 3.14 * 100 - 3.14 * 81

Evaluate the product

Region 2 = 314 - 254.34

Evaluate the difference

Region 2 =  $59.66

The cost per square inch of this region is $0.15.

So, we have:

Total cost of region 2 = 59.66 * $0.15

Total cost of region 2 = $8.949

The circle B is divided into sectors.

And the angles of the sectors are 90 and 270 degrees

The area of each sector is

Area = ∅/360 * π(d/2)^2

So, we have:

Circle B = ∅/360 * π(d/2)^2 + ⊕/360 * π(d/2)^2

So, we have:

Circle B = 90/360 * 3.14 * (18/2)^2 + 270/360 * 3.14 * (18/2)^2

Evaluate the quotient

Circle B = 0.25 * 3.14 * 9^2 + 0.75 * 3.14 * 9^2

Evaluate the exponent

Circle B = 0.25 * 3.14 * 81 + 0.75 * 3.14 * 81

Evaluate the product

Circle B = 63.585 + 190.755

The cost per square inch of this region is $0.80 for 1 sector and $0.20 for the rest

So, we have:

Total cost of circle B = 63.585 * 0.80 + 190.755 * 0.20

Total cost of circle B = 89.019

Add the total costs

Total cost of the glass for your window = Region 1 + Region 2 + Circle B

Total cost of the glass for your window = $26.10 + $59.66 + $89.019

Evaluate the sum

Total cost of the glass for your window = $174.779

Approximate

Total cost of the glass for your window = $174.8

Hence, the total cost of the glass for your window now  $174.8

u = - 4w + 9 is the rearranged equation so that w is the independent variable given that the equation is u - 5= - 4(w - 1). This can be obtained by simplifying the equation and taking w to one side of the equation with other constants.

Simplifying an equation can be done by using the following steps:

Here it is given that the equation is,

⇒ u - 5= - 4(w - 1)

We have to find an equation in which w is taken to one side of the equation with other constants.

First by adding both side of the equation with 5 we get,

⇒ u - 5 + 5 = - 4(w - 1) + 5

By opening the bracket we get,

⇒ u = - 4w + 4 + 5

Finally by adding the constants we get,

⇒ u = - 4w + 9

Hence u = - 4w + 9 is the rearranged equation so that w is the independent variable given that the equation is u - 5= - 4(w - 1).

The direction of the parabola is determined by the leading coefficient of the polynomial (a > 0 - Upwards, a < 0 - Downwards). The y-intercept of the polynomial is c and the two zeros of the polynomial are x = - b / (2 · a) ± [1 / (2 · a)] · √(b² - 4 · a · c).

Herein we have a quadratic equation of the form f(x) = a · x² + b · x + c. To determine the direction of the parabola, we must transform this expression into its vertex form and looking for the sign of the vertex constant:

f(x) = a · x² + b · x + c

f(x) = a · [x² + (b / a) · x + (c / a)]

f(x) + b² / (4 · a) - c = a · [x² + (b / a) · x + b² / (4 · a²)]

f(x) + b² / (4 · a) - c = a · [x + b / (2 · a)]²

If a > 0, then the direction of the parabola is upwards, but if a < 0, then the direction of the parabola is downwards.

The y-intercept is found by evaluating the quadratic equation at x = 0:

f(0) = a · 0² + b · 0 + c

f(0) = c

And the zeros are determined by the quadratic formula:

x = - b / (2 · a) ± [1 / (2 · a)] · √(b² - 4 · a · c)

The direction of the parabola is determined by the leading coefficient of the polynomial (a > 0 - Upwards, a < 0 - Downwards). The y-intercept of the polynomial is c and the two zeros of the polynomial are x = - b / (2 · a) ± [1 / (2 · a)] · √(b² - 4 · a · c).

Answer: 1.71, 1 3/4, 16/9, pie

Step-by-step explanation: We convert all the numbers to improper fractions. 1.71 = 171/100. 1 3/4 = 175/100 because 3/4 is 0.75. pi is 3.14... which is larger than all of the other numbers. So, pi is the largest. For 16/9, we can just divide to find the solution. Once you divide, you will notice that the answer is 1.77777777... This means that it is larger than 1.71 and 1.75 so 16/9 is the second largest. 1.71 is smaller than 1.75 so the order is 1.71, 1 3/4, pie, 16/9

A right angled triangle is a triangle that has 3 sides and angle with one of its angles to be 90 degrees.

From the given triangle, the measure of the x-coordinate point of G and H will be equal.

Since the line GH intersects the x-axis and the point where the line intersects the x-axis is where y = 0, hence the coordinate H is (a, 0) and the measure of G is (a, +y)

The y-value of G can be any positive value on the y-axis

The midpoint of PQ is (1, -0.5)

The coordinates of the point 2/3 of the way from p to q are (-0.2, 0.4)

What is the midpoint of a line segment?

the midpoint is the middle point of a line segment. It is equidistant from both endpoints.

The midpoint of PQ

To calculate this, we use the midpoint formula;

(x,y) = {(x1 + x2)/2 , (y1 + y2)/2}

From the question; (x1,y1) = (-5,4) and (x2,y2) = (7,-5)

So (x,y) = (-5+7)/2 , (4-5)/2 = 2/2, -1/2 = (1,-0.5)

The coordinates of the midpoint of PQ are (1,-0.5)

What is the internal division of the line segment?

we will use here the internal division formula of the section formula;

Mathematically the coordinates can be calculated using the formula;

(x,y) = (mx2 + nx1)/m+ n , (my2 + ny1)/m + n

in this case, m = 2 and n = 3

(x1,y1) = (-5,4)

(x2,y2) = (7,-5)

So substituting these values, we have;

(x,y) = (2(7)+ 3(-5))/(2+3) , 2(-5) + 3(4)/(2+3)

(x,y) = (14 -15)/5 , (-10 + 12)/5

= (-1/5, 2/5) = (-0.2, 0.4)
