divide using synthetic division (2x^3 + 14x^2 - 58x) / (x + 10) 58 POINTS!!!!

Answers

Answer 1
-10 | 2 14 -58
-20 -60
2 -6 -118

So it's 2x^2 -6x The remainer is -118

Set x + 10 = 0

So that's how I get -10

I then multiplied -10 x 2 to get -20 and placed it below 14. -20 + 14 is -6. -6 x -10 is -60. -58 + -60 is -118. 2 remains the same since you didn't do anything with.

Since you started with 2x^3 and this is division, you immediately know the first term will start with x^2 so that's how I get 2x^2. The ending number, in this case -118, is always the remainder.

Answers

Proof by Contraposition.

Let me know if I was correct or horribly wrong.

Answer: Conditional statement

Step-by-step explanation:

In discrete mathematics, a conditional statement denoted by "if R then S " is an if-then statement where R represents a hypothesis and S represents a conclusion.

For example : If a number is divisible by 6 ,then it must be divisible by 2 ."

Here, Hypothesis R: " number is divisible by 6"

Conclusion S: "it must be divisible by 2"

Hence, an conditional statement  has the form " if A, then B" .

How to Graph y=4/5x-7

Answers

Final answer:

To graph the equation y = 4/5x - 7, plot the y-intercept at -7 and use the slope to find a second point before drawing a line through the two points.

Explanation:

To graph the equation y = 4/5x - 7, follow these steps:

Start by plotting the y-intercept at -7 on the y-axis.Use the slope 4/5 to find a second point by moving up 4 units and to the right 5 units. Plot this point.Draw a straight line through these two points to represent the graph of y = 4/5x - 7.

The hexagon GIKMPR and FJN are regular. The dashed line segments form 30 degree angles.
What is? (attached)

Answers

The dashed line segments form 30-degree angles in the given diagram of a regular hexagon and triangle.

In the given diagram, hexagon GIKMPR and triangle FJN are regular. The dashed line segments form 30-degree angles.

Since hexagon GIKMPR is regular, all its interior angles are equal. Each angle of a regular hexagon is 120 degrees, so angle GIK is 120 degrees.

The angle at GIK can be split into two equal angles by the dashed line segment, so each of these angles measures 60 degrees.

Similarly, since triangle FJN is regular, each of its angles measures 60 degrees.

Therefore, the dashed line segments form two 30-degree angles each side of the regular hexagon and triangle.

The correct answer is option d. The image of [tex]\overline{OQ}[/tex] after a rotation of 300 degrees about point O is [tex]\overline{OF}[/tex].

To find the image of line segment [tex]\( \overline{OQ} \)[/tex] after a rotation of [tex]\( 300^\circ \)[/tex] about point O, we need to understand that a rotation of [tex]\( 300^\circ \)[/tex] is equivalent to rotating [tex]\( 60^\circ \)[/tex] clockwise. This is because rotating [tex]\( 360^\circ \)[/tex] would bring us back to the original position, so a rotation of [tex]\( 300^\circ \)[/tex] is the same as rotating [tex]\( 360^\circ - 60^\circ = 300^\circ \)[/tex].

Given that line segment [tex]\( \overline{OQ} \)[/tex] forms a [tex]\( 30^\circ \)[/tex] angle with the dashed lines, after a rotation of [tex]\( 300^\circ \)[/tex], it will form a [tex]\( 30^\circ \)[/tex] angle with the new position of the dashed lines.

Therefore, the image of line segment [tex]\( \overline{OQ} \)[/tex] after the rotation is [tex]\( \overline{OF} \)[/tex].

On an average day, 38 customers buy a bag of grapes at Jerry's Market. There are an average of 47 grapes in each bag. Round to the nearest ten and then multiply to estimate the number of grapes Jerry's customers buy every day.

Answers

round 38 to 40. round 47 to 50. then multiply the numbers together: 40 x 50 = 2000
your answer is 2000 i think,

Answer:

40 x 50 = 2,000

Step-by-step explanation:

When we round a number, first identify the digit to round. Then proceed with the following two rules:

(a) If the number to the right of the digit to round is 0, 1, 2, 3, or 4 (that is, less than 5), then keep the digit to round and change the rest of the digits to the right of the digit to round to zero.

(b) If the number to the right of the digit to be rounded is 5, 6, 7, 8, or 9 (that is, greater than or equal to 5), then add one to the digit to round and change the rest of the digits to the right of the digit to round to zero.

In our case, we apply the two rules, rounding to the nearest ten, as follows:

For 38 = 40

Apply rule (b) since 8 is greater than or equal to 5, then add 1 to 3 to get 4, then change 8 to zero. The result is 40.

For 47 = 50

Apply rule (b) since 7 is greater than or equal to 5, then add 1 to 4 to get 5, then change 7 to zero. The result is 50.

Now, multiply to estimate the amount of grapes that Jerry customers buy every day.

40 x 50 = 2,000

2x = 8 + 12
2x = 20

x = 10 <== ur number
Let's represent the number with Y
Twice the number will be 2Y
12 is subtracted from it. That will be;
2Y-12
And it is equal to 8
2Y-12=8
-12 will go over the equality sign to become +12
2Y=8+12
2Y=20
Divide both sides by 2
Y=20/2
Y=10

Which is a property of an angle?

has two sides that each extend forever in both directions
has two endpoints
has two center points
has two rays that share a common endpoint

Answers

its ¨has two rays that share a common endpoint¨

Answer:

has two rays that share a common endpoint

Step-by-step explanation:

An angle is formed by a two rays that share a common endpoint.  The distance between the two rays is what makes the measure of the angle wider or smaller.  Each ray extends in one direction forever; however since they share an endpoint, the rays do not extend in both directions forever.  There is only one endpoint, not two, and there is only one center point (vertex), not two.


Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 3 inches, and the larger gear has a radius of 7 inches.

Part 1: What is the angle measure, in degrees and rounded to the nearest tenth, through which the larger gear has rotated when the smaller gear has made one complete rotation?

Part 2: How many rotations will the smaller gear make during one complete rotation of the larger gear?

Show all work.

Answers

A)circumfrence of smaller gear is 6pi while circumference of larger gear is 14pi. thus 6pi of the 14pi would be turned so 0.4257 of the larger gear would be turned. 0.4257*360 would give us the angle, 154.3 degrees.
B)since the circumference of the larger gear is 14pi in one rotation the smaller gear would have rotated a length of 14pi. Thus 14pi/6pi=2.3 or 7/3 rotations.

In your answer, can you please show work so that I can understand it myself

Answers

Starting off, we can multiply the third equation by 2 and add it to the third to get rid of both the x and y variables. Next, we get z=1. Plugging that into 3y-5z=-23, we get 3y-5=-23. Adding 5 to both sides, we get 3y=-18. After that, we can divide both sides by 3 to get y=-6. Plugging that into -2x-y-z=-3, we get -2x+6-1=-3=-2x+5. Subtracting 5x from both sides, we get -2x=-8. After that, we can divide both sides by -2 to get x=4.

Square GHIJ shares a common center with regular hexagon ABCDEF on a coordinate plane. AB¯¯¯¯¯ is parallel to GH¯¯¯¯¯. If the combined figure rotates clockwise about its center, at which angle of rotation will the image coincide with the preimage?

60°

180°

90°

240°

Answers

a square needs to rotate 90 to coincide with  itself

 but the hexagon would need to rotate 180

the answer is 180 degrees

Answer:

Option B 180° is the right answer.

Step-by-step explanation:

Given is : GHIJ is a square and ABCDEF is a regular hexagon having common centre O.

We know that a square is symmetric at a rotational angle of 90°.

A regular hexagon is symmetric at a rotational angle of 60°.

We will find the LCM of 90 and 60, to know how much to rotate, to get a preimage.

Moreover, a hexagon needs to rotate 180 degrees to coincide with itself.

LCM(60°,90°)=180°.

So, the correct option is B. 180°.
