If two angles share a vertex then they are adjacent true or false

Answers

Answer 1

true i think hope this helps

Answer 2

The given statement is true"If two angles share a vertex then they are adjacent".

What is an angle?

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

If two angles in geometry share a side and a vertex, they are said to be adjacent. In other words, consecutive angles do not overlap and are placed side by side.

When an angle's vertex and side are shared by another angle, the two angles are said to be adjacent angles. The vertex of an angle is the point where the rays come to a stop and form the sides of the angle. When two adjacent angles share a vertex and a side, they can be either complementary or supplementary angles.

Thus, the given statement is true"If two angles share a vertex then they are adjacent".

what is the slope of the function?

Answers

the answer is three work is in picture

Answer:

The answer is 3.

Step-by-step explanation:

In order to determine the slope of the function, we have to know about linear function.

In any linear function, we can get its slope using two pairs of coordinates that belong to the linear function.

m=Slope of the linear function.

P1=(x1,y1)=First pair of coordinate.

P2=(x2,y2)=Second pair of coordinate.

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

In this case, we have many pairs of coordinates, so we choose two of them:

[tex]P_1=(-1,1)\\P_2=(0,4)[/tex]

Then, we replace them in the slope formula:

[tex]m=\frac{4-1}{0-(-1)}=\frac{3}{1}=3[/tex]

Finally, the slope of the function is 3.

Which statement is true about the difference 2√7-√28

Answers

It seems like there are answer choices but you forgot to post them. If you want to simplify then

2*sqrt(7) - sqrt(28) = 2*sqrt(7) - sqrt(4*7)
2*sqrt(7) - sqrt(28) = 2*sqrt(7) - sqrt(4)*sqrt(7)
2*sqrt(7) - sqrt(28) = 2*sqrt(7) - 2*sqrt(7)
2*sqrt(7) - sqrt(28) = (2-2)*sqrt(7)
2*sqrt(7) - sqrt(28) = (0)*sqrt(7)
2*sqrt(7) - sqrt(28) = 0

So the whole complicated expression simplifies to 0 (zero)

This is because sqrt(28) = 2*sqrt(7) when you simplify sqrt(28)

two cruise ships are sailing towards each other from caribbean islands that are 264 km apart, one ship travels 4 km/h faster than the other. if they both started at the same time. and meet after 6h. how fast is the other ship travelling?

Answers

Final answer:

The slower ship is traveling at a speed of 21 km/h, while the faster ship is traveling at a speed of 25 km/h.

Explanation:

This is a mathematics problem that involves solving for unknown speeds with the given conditions. Lets assume the speed of the slower ship is x km/h. Thus, the speed of the faster ship is x+4 km/h. They are moving towards each other, thus their combined speed is (x+x+4) km/h. As speed is distance over time, we can set up the equation: (2x+4)*6 = 264. Solving this equation, we end up with x=21 km/h as the speed of the slower ship, and hence the speed of the faster ship is 25 km/h.

Cynthia besch wants to buy a rug for a room that is 18 ft wide and 30 ft long. she wants to leave a uniform strip of floor around the rug. she can afford to buy 220 square feet of carpeting. what dimensions should the rugâ have?

Answers

Since the strip around the outside of the rug will be uniform, the dimensions of the rug will have the form (18 - x) in width and (30 - x) in length, where x is equal to twice width of the strip. We can use this data to set up an equation. (18 - x) (30 - x) = 220 x^2 - 48 x + 540 = 220 x^2 - 48 x + 320 = 0 (x - 8) (x - 40) = 0 x = 8 or x = 40 Since x = 40 is too wide for the strip, the correct solution is x = 8 The width of the rug is: 18 - x = 10 feet The length of the rug is: 30 - x = 22 feet The dimensions of the rug are 10 feet x 22 feet. Note that the area is equal to 220 square feet.

Answers

When performing addition and multiplication with constant numbers, we treat i as we would treat any variable x in an expression, with the same rules and properties of addition and multiplication.

1)

[tex]( 7 + 5i) - ( -9 + i)=7+5i+9-i=(7+9)+(5i-i)=16+4i[/tex]

2)
Distribute 7+7i over 6 and 7i:

[tex]( 7 + 7i)( 6 + 7i)=( 7 + 7i)\cdot6+( 7 + 7i)\cdot7i=42+42i+49i+49i^2[/tex]

collecting similar terms, and substituting [tex]i^2[/tex] with -1 we have:

42+91i-49=-7+91 i

3)

The conjugate of a complex number a+bi is a-bi;
the conjugate of 1+3i is 1-3i.

Thus, using the difference of squares formula we have

[tex](1+3i)(1-3i)=1^2-(3i)^2=1-9i^2=1-9(-1)=1+9=10[/tex]

4)

To write a rational expression ( with a complex number in the denominator) in the standard form, we multiply by the conjugate of the denominator both the numerator and the denominator:

[tex]\displaystyle{ \frac{3}{3-12i}= \frac{3(3+12i)}{(3-12i)(3+12i)}= \frac{9+36i}{3^2-(12i)^2} [/tex]

[tex]=\displaystyle{ \frac{9+36i}{9+144}= \frac{9+36i}{153}= \frac{9}{153}+ \frac{36}{153}i [/tex]

simplifying by 9, the complex number is finally written as

[tex]\displaystyle{ \frac{1}{17}+ \frac{4}{17}i [/tex]

5)

Reflection : Across the line y = 1

Answers

What is the question supposed to be?

Reflecting across y = 1 means each point's position stays the same horizontally but mirrors vertically across the line.

When reflecting a point or shape across a line, y = 1,

it means that each point is mirrored on the other side of the line while maintaining the same distance from the line.

Here, the line y = 1 acts as a "mirror" or "axis of reflection."

To reflect a point (x, y) across the line y = 1, follow these steps:

Find the vertical distance between the point and the line y = 1. Let's call this distance "d."

If the point is above the line (y > 1), then d = y - 1.

If the point is below the line (y < 1), then d = 1 - y.

Move the point to the same vertical distance on the other side of the line y = 1.

If the point was above the line (y > 1), the new reflected point will be (x, 1 + d).

If the point was below the line (y < 1), the new reflected point will be (x, 1 - d).

Keep in mind that the x-coordinate remains the same in both cases since the line of reflection is vertical (parallel to the y-axis).

By repeating these steps for all points in a shape, obtain the reflection of the entire shape across the line y = 1.

the total points scored in a basketball game can be calculated using the expression 3c - 3 if c = 41, how many points total were scored

Answers

Answer:

its actually 126

Step-by-step explanation:

Final answer:

The total points scored in the basketball game is 120 points.

Explanation:

To find the total points scored in a basketball game, we can use the expression 3c - 3. Given that c is equal to 41, we can substitute this value into the expression to calculate the total points.

So, 3c - 3 = 3(41) - 3 = 123 - 3 = 120.

Therefore, a total of 120 points were scored in the basketball game.

Assume that lines that appear to be parallel are parallel. Find the value of x and the measure of angle y

Answers

What information have we been given here? From the diagram, we can see that (9x+1)° and (14x-34)° degrees are supplementary, meaning:

(9x+1)+(14x-34)=180

There, we have an equation we can fairly easily solve for x. What about y?

If we take a look at the line y° occupies, we can see that it shares a straight angle with our (14x-34)° term and - as implied by the right angle on the bottom line - a 90° angle.

All three of these should add up to 180°, so we have:

(14x-34) + y + 90 = 180

Another think to note is that, upon inspection, (14x-34)° and y° are complementary - they add up to 90° - and subtracting the 90 from both sides of our equation confirms that fact:

(14x-34) + y = 90

If you've solved for x prior to this, solving for y should be pretty straightforward.

Answer:

The answer would be (14x-34) + y = 90.

The length of a rectangle is 3 meters less than twice the width. if the area of the rectangle is 527 square meters, find the dimensions.

Answers

The rectangle is 17 meters wide and 31 meters long. To solve this problem, first work out the equation for the length of the rectangle. Using the information given, we find that length (L) is given by L=2W-3. Next we setup the formula for the area of a rectangle, A=(W)(L). We are told that the area is 527 sq. meters, so our equation is 527=(W)(L). We also know that L=2W-3, so we can plug that into the equation for area as well which gives us 527=W(2W-3), which can be written 0=2(W^2)-3W-527. We now need to solve this equation for W. Factoring the left side we get, 0=(W-17)(2W+31). Thus, either (W-17)=0 or (2W+31)=0 must equal zero. Solving these two equations, we get W=17 or W=-15.5. Since we are looking for the width (which is a length), we know it cannot be negative and therefore the width must be 17 meters. Now that we know the width, we can plug W=17 back into the equation for length (L=2W-3). Doing this give us L=2(17)-3 which is equal to 31. Thus the length is 31 meters.

w=17
