A coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. Line A passes through the ordered pairs negative 8, 5 and 4, negative 7. Line B passes through the ordered pairs negative 3, 8 and 2, negative 7. Line C passes through the ordered pairs 0, 9 and negative 7, negative 5. Line D passes through the ordered pairs 1, 4 and negative 4, negative 1 and is extrapolated further in the quadrant.

Answer:

254.34 in²

Step-by-step explanation:

Assuming that the shape is a circle,

area of circle= πr², where r= radius.

Given that the diameter is 18 in,

radius= diameter ÷2

radius= 18 ÷2

radius= 9 in

Let's substitute r= 9 and use 3.14 as the value of π:

Area of circle

= 3.14(9²)

= 3.14(81)

= 254.34 in²

Answer:

-8

Step-by-step explanation:

The opposite of a positive integer is a negative integer so it must be -8

Answer:

%26

Step-by-step explanation:

We can set up a proportion to find out what percentage of the gumballs are red:

[tex]\frac{525252}{232323+525252+343434+616161+303030} =\frac{x}{100}[/tex]

[tex]\frac{525252}{2020200} =\frac{x}{100}[/tex]

[tex](525252)(100)=2020200(x)[/tex]

[tex]\frac{(525252)(100)}{2020200} =x[/tex]

[tex]26=x[/tex]

Since we set up x as a fraction of 100 when writing the proportion we can say that the percentage of red gumballs is %26.

Answer:

Given a triangle ABC, Pythagoras' Theorem shows that:

[tex]c^2=a^2+b^2[/tex]

Thus,

[tex]c = \sqrt{a^2+b^2}[/tex]

The distance formula, gives an equivalent expression based on two points at the end of the hypotenuse for a triangle.

[tex]d^2 = (x_{2} -x_{1})^2 + (y_{2} -y_{1})^2[/tex]

[tex]d = \sqrt{(x_{2}-x_{1})^2 + (y_{2} -y_{1})^2 }[/tex]

Therefore when given the hypotenuse with endpoints at

[tex](x_{1}, y_{1}) and {(x_{2}, y_{2})[/tex]

We know that the third point of the right triangle will be at

[tex](x_{2}, y_{1})[/tex]

and that the two side lengths will be defined by the absolute values of:

[tex](x_{2} - x_{1}) = a[/tex]

[tex](y_{2} - y_{1}) = b[/tex]

Answer:

561 is the surface area

Step-by-step explanation:

11 x 11 is the base area which equals 121. The height is 10 and the base is 11 for the triangles so it is 11 x 10 which equals 110. We multiply that number by 4 to equal 440. 440 + 121 equals 561 so 561 is the surface area.

Answer:

Step-by-step explanation:

((10 x 11)/2) x 4

=220

220+11 x 11

220 + 121=

The sequences of transformations that could be applied to the parent function are (e) Reflect over the y-axis, vertically stretch by a factor of 2, and then shift up 6 units

The graph that completes the question is added as an attachment

From the attached graph, we have the following points

(3, 0) and (0, 6)

Calculate the equation of the line using

[tex]g(x) = \frac{y_2 - y_1}{x_2 -x_1} * (x - x_2) + y_2[/tex]

This gives

[tex]g(x) = \frac{6 - 0}{0 -3} * (x - 0) + 6[/tex]

Evaluate the quotient

g(x) = -2 * (x) + 6

Expand

g(x) = -2x + 6

This means that the equation of the line is:

g(x) = -2x + 6

So, we have:

f(x) = x as the parent function and g(x) = -2x + 6 as the transformed function.

The transformations from f(x) to g(x) are as follows:

Hence, the sequences of transformations that could be applied to the parent function are (e) Reflect over the y-axis, vertically stretch by a factor of 2, and then shift up 6 units

The coordinate of point G is its location on the coordinate plane

The area of the triangle would not remain the same

From the question, we have the following points

G = (4,-3) and

G = (4,3)

The above coordinates are two different points, and so they would make the triangle have different areas.

Hence, the area of the triangle would not remain the same

Answer:

The answer is -8.

Step-by-step explanation:

1. Solve the upper half of the expression by following the order of operations:

10² - (100 + 8²)

10² - (100 + 64)

10² - 164

100 - 164

= -64

2. Solve the bottom half by multiplying 2 by itself three times:

2 · 2 · 2 = 8

3. Divide the now given values

The given expression is equivalent to [tex]\rm -2(x-7)^2+118[/tex]price is $7 option first is correct.

A quadratic expression is a second-degree algebraic expression represented by the:

[tex]\rm ax^2+bx+c=0[/tex] ........(1)

Where a, b, and c are the constants and  

We have a quadratic expression:

[tex]\rm f(x)=-2x^2+28x+20[/tex]

Convert it to perfect square by perfect square trinomial:

[tex]\rm f(x)=-2(x^2+14x)+20[/tex]  

[tex]\rm f(x)=-2(x^2+14x+49-49)+20[/tex]   (adding and subtracting by 49)

[tex]\rm f(x)=-2(x-7)^2+2(49)+20[/tex]

[tex]\rm f(x)=-2(x-7)^2+118[/tex]

Here [tex]\rm (x-7)^2[/tex] is the positive term and -2 is the negative term so in order to get the highest weekly profit it should be zero, so

[tex]\rm -2(x-7)^2=0[/tex]

x = $7

Thus, the given expression is equivalent to [tex]\rm -2(x-7)^2+118[/tex]  and the price is $7.

you must first divide 40.65 by 3 to find the cost of 1 shirt which the answer is $13.55. I hope this helps! Have a good day! :)

Since we are given the price of 3 shirts, we can work backwards to do $40.65 divided by 3 to get the unit cost per shirt, in which we get $13.55.
