Brett create a function of X with seven points each in a different location on the grid he graph sixth of the points as shown use the add point tool to show the location of a point that could be the seventh point of Brett function

Answers

Answer:

any point where x=3, 4, or 6.

Step-by-step explanation:

The thing that makes a function a function and not a relation is having only 1 y value per x value, which means if you draw a vertical line through a point, it should not intercept any other points. Basically, the main difference between a function and a relation is that a function can't have 2 points on top of each other.

Pick a point where x=3, 4, or 6. Those are the open spots on the grid with nothing above or below them. It doesn't matter which point you pick, as long as there is NOTHING directly above or below that point.

I hope you understood this solution. Happy mathing!

Answer:

[tex]n = 32[/tex]

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

~

First, add 10 to both sides of the equation:

[tex]\frac{n}{2} - 10 = 6\\\ \\\frac{n}{2}- 10 (+10) = 6 (+10)\\ \\\frac{n}{2} = 6 + 10\\\\\frac{n}{2} = 16[/tex]

Next, isolate the variable n by multiply 2 to both sides of the equation:

[tex]\frac{n}{2} = 16[/tex]

[tex]\frac{n}{2} *2 = 16 * 2[/tex]

[tex]n = 16 * 2\\n = 32[/tex]

[tex]n = 32[/tex] is your answer.

Frank drives 60 miles per hour, and this relationship is graphed, which ordered pair would not be on the graph?

Answers

Answer:

4 and 280

Step-by-step explanation:

4,280

Reason:
Frank drives 60miles per 1 hour ( 1:60)
If he drives 120miles, its per 2hours because you multiply by 2.
If he drives 360miles, its per 6 hours
Because 60x6=360 and 1x6=6 (6:360)
4,280 is odd one out because if he drives 4hours, you multiply 60 by 4 to get 240, 280 is incorrect

The diagram is shown below what happens when you dilate with a scale factor 2/3, and the center of dilation is D.

Line AD and line A'D' are the same line, since D = D'. Recall that the center of dilation does not move when applying a dilation. Point A moves to A', which is one line AD. Due to D being at the center, all lines from the center will connect the four points shown.

Oatmeal is packaged in a right circular cylindrical container that has a radius of 2.5 inches and a height of 10 inches.

What is the surface area of this container in terms of π?

Answers

Answer:

surface area: 62.5π

explanation:

total surface area of cylinder: 2πr(h+r)

Given:

radius = 2.5 inchheight = 10 inch

Solve:

2π(2.5)(10+2.5)

5π(12.5)

62.5π

Solution:

Given:

Radius of cylinder: 2.5 inHeight of cylinder: 10 in

Surface area of cylinder: 2πrh + 2πr²

Using the formula:

[tex]2\pi rh + 2\pi r^{2} = \text{Surface area of cylinder}[/tex]

[tex]\rightarrow 2(3.14)(2.5)(10) + 2(3.14)(2.5)^{2} = \text{Surface area of cylinder}[/tex]

Simplifying the LHS:

[tex]\rightarrow (3.14)(50) + 2(3.14)(6.25) = \text{Surface area of cylinder}[/tex]

[tex]\rightarrow (31.4)(5) + (6.28)(6.25) = \text{Surface area of cylinder}[/tex]

[tex]\rightarrow \boxed{\bold{196.25 \ in^{2} = \text{Surface area of cylinder}}}[/tex]

Answers

Answer:

40 miles

Step-by-step explanation:

First, change the 15 minutes to 0.25 hours and 3 minutes to 0.05 because we are working with mph.

let x be the normal driving time to work in hours so 40x is the driving to work

since we know distance = speed multiplied by time we do

50(x-0.25+0.05)=40x

50(x-0.2)=40x

50x-10=40x

50x-40x=10

10x=10

x=1 hour normal time to work

therefore

40(1) = 40 mi to work

Confirm this by finding the dist when he went 50 mph for 48 min (0.8hrs)

50(1-.25+0.05) = 50(.8) = 40 mi also

Solution (1):

We know that:

Sum of the angles in a quadrilateral = 360°Base angles of a trapezoid are equalTop angles of a trapezoid are equal

This means that:

[tex]130 + 130 + \angle1 + \angle1 = 360[/tex]

Let's simplify the equation to find ∠1.

Step-by step calculations:

Add the constants:

[tex]260 + \angle1 + \angle1 = 360[/tex]

Add the angles:

[tex]260 + 2\angle1 = 360[/tex]

Subtract 260 both sides:

[tex]260 - 260 + 2\angle1 = 360 - 260[/tex]=> [tex]2\angle1 = 100[/tex]

Divide 2 both sides:

=> [tex]\frac{2\angle1}{2} = \frac{100}{2}[/tex]=> [tex]\bold{\angle1 = 50\°}[/tex]Solution (2):

We know that:

Sum of the angles in a quadrilateral = 360°

This means that:

Let's simplify the equation to find ∠1.

Step-by step calculations:

Simplify the LHS:

[tex]109 + 87 + 90 + \angle1 = 360\°[/tex]=> [tex]286 + \angle1 = 360\°[/tex]

Subtract 286 both sides:

=> [tex]286 - 286 + \angle1 = 360 - 286[/tex]=> [tex]\angle1 = 360 - 286[/tex]
