Please answer #5

Point M Is The Midpoint Of AB If The Coordinates Of A Are (-3,6) And The Coordinates Of M Are (-5,2)

Answers

Answer 1

Answer:

The coordinates of point B are (-7 , -2)

Step-by-step explanation:

* Lets explain how to solve the problem

- The mid-point (x , y) of the line whose endpoints are (x1 , y1) and

 (x2 , y2) is [tex]x=\frac{x_{1}+x_{2}}{2},y=\frac{y_{1}+y_{2}}{2}[/tex]

∵ M is the midpoint of AB

∵ The coordinates of point A are (-3 , 6)

∵ The coordinates of point M are (-5 , 2)

- Let the coordinates of point A are (x1 , y1) , The coordinates of

 point B are (x2 , y2) and The coordinates of point M are (x , y)

∴ x = -5 , x1 = -3 and y = 2 , y1 = 6

- Lets use the rule of the mid point to find x2 , y2

∵ [tex]-5=\frac{-3+x_{2}}{2}[/tex] ⇒ multiply both sides by 2

∴ [tex]-10=-3+x_{2}[/tex] ⇒ add 3 to both sides

∴ -7 = x2

∵ [tex]2=\frac{6+y_{2}}{2}[/tex] ⇒ multiply both sides by 2

∴ [tex]4=6+y_{2}[/tex] ⇒ subtract 6 from both sides

∴ -2 = y2

∵ The coordinates of point B are (x2 , y2)

∴ The coordinates of point B are (-7 , -2)

Figure ABCD is rotated clockwise about the origin through 90°. Identify the coordinates for the given figure after 90° rotation about the origin.​

Answers

Answer:

D[3, 3], C[1, 4], B[0, 1], A[4, -1]

Step-by-step explanation:

Whenever you are doing a 90° clockwise rotation ABOUT THE ORIGIN, it is in the form of [y, -x], meaning you take the y and make it your x, then take your original x and put its OPPOSITE.

90° counterclockwise rotation → [-y, x]

Charlie divided 15 cents among
four small bags.
He can use the four bags to pay any
amount between 1 cent and 15 cents, Bag without opening them.
How many cents did Charlie put in each bag?​

Answers

Answer:0.035

Step-by-step explanation:

I used a calculator and put in 15 / 4 and got 0.035

Final answer:

Charlie should divide the 15 cents into four bags with 1 cent, 2 cents, 4 cents, and 7 cents respectively. Using combinations of these bags, he can pay any amount between 1 cent and 15 cents without opening them.

Explanation:

The question asks us to figure out how Charlie can divide 15 cents among four small bags so he can use these bags to pay any amount between 1 cent and 15 cents without opening them.

To solve this, we need to think about the binary representation of numbers, because each bag can either be used or not used in each transaction, similar to how a binary '1' or '0' can represent 'on' or 'off'.

Therefore, he should put the amounts that correspond to the powers of 2 in three of the bags: 1 cent, 2 cents, and 4 cents, and in the last bag, we put the sum of these three, which is 7 cents.

This way, he can make any amount up to 15 cents:

1 cent: Use the 1-cent bag.2 cents: Use the 2-cent bag.3 cents: Use the 1-cent and 2-cent bags.4 cents: Use the 4-cent bag.5 cents: Use the 1-cent and 4-cent bags.6 cents: Use the 2-cent and 4-cent bags.7 cents: Use the 1-cent, 2-cent, and 4-cent bags.8 cents: Use the 7-cent bag.9 cents: Use the 1-cent and 7-cent bags.10 cents: Use the 2-cent and 7-cent bags.11 cents: Use the 1-cent, 2-cent, and 7-cent bags.12 cents: Use the 4-cent and 7-cent bags.13 cents: Use the 1-cent, 4-cent, and 7-cent bags.14 cents: Use the 2-cent, 4-cent, and 7-cent bags.15 cents: Use all four bags.

Natasha has 13 apples.Some apples are red and some are green.She has more red apples than green apples.How many red apples and how many green apples could she have?

Answers

Final answer:

Natasha could have 9 red apples and 4 green apples, or 10 red apples and 3 green apples.

Explanation:

To determine the number of red and green apples Natasha could have, we need to consider the given information. Natasha has a total of 13 apples, and she has more red apples than green apples.

Let's assume that Natasha has r red apples and g green apples. We know that r + g = 13, since she has a total of 13 apples.

Given that she has more red apples than green apples, we can say that r > g.

Now, we need to find the possible values of r and g that satisfy these conditions. We can use trial and error to find the values that work:

If r = 9 and g = 4, then the statement r > g is true and r + g = 13 is also true. Therefore, Natasha could have 9 red apples and 4 green apples. If r = 10 and g = 3, then the statement r > g is true and r + g = 13 is also true. Therefore, Natasha could have 10 red apples and 3 green apples. If r = 11 and g = 2, then the statement r > g is true, but r + g = 13 is not true. Therefore, Natasha cannot have 11 red apples and 2 green apples.

Based on our analysis, Natasha could have either 9 red apples and 4 green apples, or 10 red apples and 3 green apples.

Paul wants to visit his aunt who lives 300 miles away from his house. He drives his car at about 50 miles/hour. If x represents the time spent driving and y represents the distance from his aunt’s house, which scatter plot could represent this situation?

Answers

The solution is, It would take 6 hours, to visit his aunt who lives.

What is speed?

Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

Speed = Distance/ Time.

here, we have,

given that,

Paul wants to visit his aunt who lives 300 miles away from his house. He drives his car at about 50 miles/hour.

If x represents the time spent driving.

then, we get,

An equation for that could be:

50x = 300 (X is how long it would take)

So, 50 mph• X (time spent) = 300 miles

now, we have,

50x = 300

or, x = 300/50

or, x = 6

Hence, The solution is, It would take 6 hours, to visit his aunt who lives.

B. Point X
C. The arc formed by the verticles​

Answers

Answer:

The correct answer option is B. Point X.

Step-by-step explanation:

We are given a graph where two triangles, a fixed point X and an arc is shown and we are to determine the center of rotation in it.

Center of rotation is basically a fixed point on a plane or a graph about which and figure rotates. It acts like a pivot in a door.

So here. we can see that point X is the center of rotation about which the vertex of a triangle is rotated 90° counterclockwise, forming an arc.

Find the area of the regular polygon round to the nearest tenth

Answers

bearing in mind that a diagonal line from the center of a square will give us an isosceles triangle, Check the picture below.

Answer:

The area of this polygon is 98.1 yd²

Step-by-step explanation:

Check the image below.

The diagonal line from the corner of a square to the center of this one will shape an isosceles triangle.

The Pythagoras theorem give us the following formula:

A² + A² = H²

Both "A" are the sides and H is the hypotenuse, seeing the figure, the diagonal coincide with the hypotenuse and the measure is 7 yd.

A² + A² = 72  

2A² = 49

A²= 49/2

A²= 24. 5

A=√24.5

A= 4.95 yd

Knowing that the diagonal ends up in the center of the square, we assume that the side of the triangle (“A” side) is the half of the side of the square, then this last one is 2A. Bearing in mind that square have all of the sides with the same measure, the four sides have a 2A size.

2A = 2(4.95) =9.9 yd

Each side of the square measures 9.9 yd

The area of a square is  

Side²= (2A)2²

(9.9)²= 98.1 yd²

The area of this polygon is 98.1 yd²

A rectangular solid object is 3 in. high, 6 in. long and 2 in. wide. What is its volume?

Answers

Answer:

The volume is 36 inches cubed.

Step-by-step explanation:

The volume of a rectangular prism is W*L*H.

You are given the H=3i, W=2 in, and L=6 in.

So now we plug into our formula for the volume of a rectangular prism which will result in 2*6*3=12*3=36.

The volume is 36 inches cubed.

Answer: [tex]36\ in^3[/tex]

Step-by-step explanation:

The volume of a rectangular prism can be calculated with this formula:

[tex]V=lwh[/tex]

Where "l" is the lenght, "w" is the width and "h" is the height.

In this case we know that this rectangular solid is 3 inches high, 6 inches long and 2 inches wide. Then:

[tex]h=3\ in\\l=6\ in\\w=2\ in[/tex]

Then, substituting these values into the formula, we get that its volume is:

x^2+8x+16=0

As per the formula (a+b)^2= a^2 +2ab +b^2

x^2+2(4)x+(4)^2=0

(x+4)^2=0

x+4=0

x=-4!

Answer:

x=-4

Step-by-step explanation:

Hello,

thanks for leaving your query here in brainly. I think I can help you with this

[tex]2x^{2} +8x=x^{2} -16\\organizing\ the\ terms\\2x^{2} +8x-x^{2}+16=0\\x^{2}+8x+16=0\\[/tex]

this can be factorized as

[tex]x^{2}+8x+16\\a^{2}  +2ab+b^{2}=(a+b)^{2}\\ x^{2}+8x+16=(x+4)^{2}[/tex]

hence

[tex](x+4)^{2}=0\\now, isolate\ x\\\\\sqrt[]{(x+4)^{2}} =\sqrt{0}\\ x+4=0\\x=-4\\[/tex]

I hope it helps, Have a nice day.
