Answer:

  a.  -165°

Step-by-step explanation:

The line from A through P to A' is almost straight, so an angle near 180° is indicated. In the figure, A' is to the left of the line AP, so clockwise rotation is indicated.

The rotation angle is a negative angle near 180°. The best choice is ...

  a.  -165°

Answer: A 165

Answer:

N = 6

Step-by-step explanation:

1:Since the answer is 9,you can do it like this:Take away the 5 from the 15,which equals 10. Then,subtract 1 so you can get 9. Therefore,the answer is 6.

2:To check your answer,do 15 minus 9.

Answer & Step-by-step explanation:

C = 2πr

3) 2π(53) ≈ 197.9

4) 2π(35) ≈ 219.9

5) 2π(21.5) ≈ 135

I'll let you formulate the last one :)

Answer:

The two are NOT THE SAME function.

Step-by-step explanation:

The linear function that is expressed as the equation y = -x + 3, is given in the slope-intercept form, y = mx + b, where

m = slope = -1

b = y-intercept = 3

To know if this function is the same with function expressed in the table of values, let's find the slope (m) and y-intercept (b) of the function represented as a table.

✔️Slope = change in y / change in x = ∆y/∆x

Using two pairs of values form the table, say, (-4, 1) and (-2, -1):

Slope (m) = (-1 - 1) / (-2 - (-4)) = -2/2 = -1

slope (m) = -1

To find b, substitute (x, y) = (-4, 1) and m = -1 into y = mx + b,

Thus:

1 = (-1)(-4) + b

1 = 4 + b

1 - 4 = b

-3 = b

b = -3

Write the equation for the table of values by substituting b = -3 and m = -1 into y = mx + b

Thus:

y = (-1)x + (-3)

y = -x - 3

As you can see, the equation of the function of the table of values is different from the equation of the function that was stated earlier.

Therefore, we can conclude that the two functions are not the same function expressed in different ways.

Answer:

  (a, b) = (4, 8)

Step-by-step explanation:

Writing both equations in general form, we have ...

  6a -5b +16 = 0

  9a -7b +20 = 0

__

We can make a little array of the numbers in the equations:

  [tex]\left[\begin{array}{cccc}6&-5&16&6\\9&-7&20&9\end{array}\right][/tex]

Note that the first column is repeated at the end.

Now, we can "cross multiply" and form the differences of products in adjacent columns:

  d1 = (6)(-7) -(9)(-5) = 3 . . . . . . left 2 columns

  d2 = (-5)(20) -(-7)(16) = 12 . . . . . middle 2 columns

  d3 = (16)(9) -(20)(6) = 24 . . . . . right 2 columns

Then the solutions to these equations are the solutions to ...

  1/d1 = a/d2 = b/d3

  a = d2/d1 = 12/3 = 4

  b = d3/d1 = 24/3 = 8

The values of a and b are 4 and 8, respectively.

Additional Comment

There are a number of ways to solve linear equations. This is similar to what you would get by doing "elimination". It is also similar to Cramer's Rule and Vedic math techniques. The number of math operations is about the same*. Once you learn the technique, it is fairly fast and requires no decision-making. My other favorite method is using a graphing calculator.

__

* This method uses 6 multiplications, 3 subtractions, 2 divisions. In the general case of "elimination", where the coefficients are not "nice" (as here), you would perform 7 multiplications, 4 subtractions and 2 divisions. This method is less work when the coefficients don't cancel easily.

Answer:

distance from the Water Slide to Roller Coaster 2

Step-by-step explanation:

✔️Distance from Roller Coaster 1 (-6, 7) to Roller Coaster 3 (-6, -3):

Distance = |7 - (-3)| = |7 + 3| = 10 units

✔️Distance from the Water slide (8, -8) to Roller Coaster 2 (-6, -8):

Distance = |8 - (-6)| = |8 + 6| = 14 units

✔️The distance from the Water Slide to Roller Coaster 2 (14 units) is greater than the distance from Roller Coaster 1 to Roller Coaster 3 (10 units)

Answer:

63 ft²

Step-by-step explanation:

Given:

Area of rectangle = [tex] A_1 = 72 ft^2 [/tex]

Area of trinagle = [tex] A_2 = 9 ft^2 [/tex]

Required:

Square feet of outdoor carpet needed for the hole

Solution:

The square feet of outdoor carpet needed = area of the rectangle - area of the triangle

= [tex] A_1 - A_2 [/tex]

= [tex] 72 - 9 = 63 [/tex]

The square feet of outdoor carpet needed is 63 ft²

Answer:

b = 13.27

Step-by-step explanation:

b^2 + 7^2 = 15^2

b^2 + 49 = 225

b^2 = 176

b = sqrt(176)

b = sqrt(16 * 11)

b = 4sqrt(11)

b = 13.27
