Answer:

8) interior angle = 160

9) x = 20

Step-by-step explanation:

8)

18-gon has 18 sides

The formula for sum of interior angles for an 18-gon is:

(18x180)-360 = 2880 degrees

2880 degrees / 18 angles = 160 degrees

9)  

exterior angles = 360 degrees

360 = (3x-2)+(x+8)+(4x+9)+(2x-1)+(3x)+(4x+6)

360 = 3x-2+x+8+4x+9+2x-1+3x+4x+6

360 = 17x+20

17x = 340

x = 20 degrees

Answer:

Step-by-step explanation:

[tex]d=vt-\frac{at^2}{2} \\ \\ a=\frac{2(d-vt)}{t^2} \\ \\ a=\frac{2(500-300(20)}{20^2} \\ \\ a=-27.5 \frac{m}{s^2}[/tex]

The acceleration of the tram is 1 m/s^2.

To find the acceleration of the tram, we can use the following equation:

acceleration (a) = (change in velocity) / (time taken)

First, let's convert the initial velocity to m/s:

Initial velocity = 300 m/minute

To convert to m/s, we need to divide by 60 (since there are 60 seconds in a minute):

Initial velocity = 300 m/minute ÷ 60 seconds/minute = 5 m/s

Now, let's find the final velocity. The tram travels a distance of 0.5 km in 20 seconds.

Distance traveled = 0.5 km = 500 m (since 1 km = 1000 m)

Time taken = 20 seconds

Now, we can find the final velocity (v) using the formula:

v = (change in distance) / (time taken)

v = 500 m / 20 seconds = 25 m/s

Next, we can find the change in velocity:

change in velocity = final velocity - initial velocity

change in velocity = 25 m/s - 5 m/s = 20 m/s

Finally, we can calculate the acceleration:

acceleration (a) = (change in velocity) / (time taken)

acceleration (a) = 20 m/s / 20 seconds = 1 m/s^2

So, the acceleration of the tram is 1 m/s^2.

Answer:

Domain: (-∞, ∞) or All Real Numbers

Range: (0, ∞)

Asymptote: y = 0

As x ⇒ -∞, f(x) ⇒ 0

As x ⇒ ∞, f(x) ⇒ ∞

Step-by-step explanation:

The domain is talking about the x values, so where is x defined on this graph? That would be from -∞ to ∞, since the graph goes infinitely in both directions.

The range is from 0 to ∞. This where all values of y are defined.

An asymptote is where the graph cannot cross a certain point/invisible line. A y = 0, this is the case because it is infinitely approaching zero, without actually crossing. At first, I thought that x = 2 would also be an asymptote, but it is not, since it is at more of an angle, and if you graphed it further, you could see that it passes through 2.

The last two questions are somewhat easy. It is basically combining the domain and range. However, I like to label the graph the picture attached to help even more.

Answer:A closed, or shaded, circle is used to represent the inequalities greater than or equal to (≥) or less than or equal to (≤) . The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution. Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.Step 1: Line up the equations so that the variables are lined up vertically. Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same. Step 3: Subtract the two equations.

Answer:

 4.50

Step-by-step explanation:

4 = Whole number. 1 = Numerator. 2 = Denominator. To get 4 1/2 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.

The decimal form of  4 and 1/2  is 4.5

Decimal is a fraction written in a unique form. The dot notation is used to represent the fraction form.

Therefore, 4 and 1/2 in decimal form is represented as follows;

Mixed fraction = 4  1 / 2

Improper fraction = 9 / 2

decimal form of  1 / 2 = 0.5

Therefore, 4 1 / 2 = 4.5

Let [tex]x[/tex] denotes number of cups of orange juice needed by Sam.

Number of cups needed to make punch [tex]=7\frac{1}{2} =\frac{15}{2}[/tex]

Number of cups with Sam [tex]=5\frac{1}{3}=\frac{16}{3}[/tex]

Answer A=48

Step-by-step explanation:

Took the test got it right.

The expression (2w - 2)³ × (8w⁶) is equivalent to :

64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.

Given is the expression as -

(2w - 2)³ × (8w⁶)

The given expression is -

(2w - 2)³ × (8w⁶)

{2(w - 2)}³ × (8w⁶)

8(w - 1)³ × (8w⁶)

(a+b)³ = a³ - 3a²b + 3ab² - b³

So, on expanding, we will get -

8(w³ - 1 - 3w² + 3w) x (8w⁶)

(8w³ - 8 - 24w² + 24w )(8w⁶)

64w⁹ - 64w⁶ - 192w⁸ + 192w⁷

Therefore, the expression (2w - 2)³ × (8w⁶) is equivalent to :

64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.

Answer:

It means that x = 20

Step-by-step explanation:

After solving the given equations, the value obtained for x and y will be equal to (1, 2).

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given equations in the question,

4x + 3y = 10      (i)

9x - 4y = 1        (ii)

Multiply equation (i) by 9 and multiply equation (ii) by 4  

36x + 27y = 90

36x - 16y = 4

A similar term of x will cancel out from here.

y = 86/43

y = 2

Put y = 2 in equation (i)

4x + 3(2) = 10

4x = 4

x = 1
