Answer:

Step-by-step explanation:

D²=290²+2030²

=290²+(290×7)²

=290²+290²×7²

=290²(1+7²)

=290²(1+49)

=290²×50

=290²×25×2

=290²×5²×2

D=290×5×√2

D=1450√2

Answer:

These are Vertical angles, adjacent angles are next to each other and make up a whole angle, while vertical angles are across and equal the same thing.

X = 81 because 84 and (x + 3) are the same so 84 minus 3 is 81

Answer:

x = 25

Step-by-step explanation:

the line QC is parallel to BR

Then

x/15 = 40/24

Then

24x = 40×15

Then

24x = 600

Then

x = 600/24

Then

x = 25

The angle of depression of the airplane is 39.8°, length of the runway is 45794 ft, and approximate height of the tower is 321 m.

The angle of depression of the airplane is given as follows:

Let the angle of depression be A.

[tex]A= {tan}^{ - 1} ( \frac{15000}{8000} ) = {39.8}^{o} [/tex]

Angle of depression is 39.8°.

If the angle of elevation is 6.8°, the length of the runway l is calculated thus:

horizontal distance of airplane from end of runway = d

length of runway, L = d - 80000 ft

[tex]d = \frac{15000}{tan 6.8°} = 125794 ft[/tex]

L = 125794 - 80000

L = 45794 ft

The length of the runway is 45794 ft

2. Let the height of the tower be H

[tex]H = \tan(69.8) \times 118 = 321m[/tex]

The approximate height of the tower is 321 m

Answer:

  dilation by a factor of -1/2 about the center (6, 5)

  (x, y) ⇒ (9 -x/2, 7.5 -b/2)

Step-by-step explanation:

Figure B is half the size of Figure A. It has been rotated, and translated. The single transformation must have all of these effects.

__

The orientation of shape B is the same as that of shape A. The small extension from the rectangle still points counterclockwise relative to the figure's center. However, it points west instead of east, signifying a rotation of 180°. The same 180° rotation can be accomplished by a reflection across a point.

Shape B has half the dimensions of shape A. That means it has been dilated by a factor of 1/2. The reflection across a point can be accomplished by using a negative dilation factor.

The center of the dilation must reside between the two figures in order for "reflection across a point" to be accomplished. Each point on figure A must be twice as far from that center as the corresponding point on figure B.

Corresponding points are (1, 1) on figure A, and (8.5, 7) on figure B. The center of dilation divides the line between these points into the ratio 2:1. That center can be found as ...

  (a, b) = (2(8.5, 7) +(1, 1))/3 = (17+1, 14+1)/3 = (6, 5)

The single transformation that maps figure A to figure B is ...

it will print no, because B = 3 and not 2 so it will skip the print yes line.

Answer: B

Step-by-step explanation:

The angles add to 90 degrees if they are complementary, so:

[tex]x-2+2x+5=90\\3x+3=90\\3x=87\\x=29[/tex]

So, the angles measure 29-2=27 degrees and 2(29)+5=63 degrees.

The function of the graph is y = 4(3)^x

The graph is an exponential function with the following points

(x,y)= (0,4) and (1,12)

An exponential function is represented as:

y = ab^x

Substitute (0,4) in the equation

4 = a * b^0

a = 4

Substitute a = 4 in y = ab^x

y = 4b^x

Substitute (1,12) in the equation

12 = 4b^1

12 = 4b

Divide by 4

b = 3

Substitute b = 3 in y = 4b^x

y = 4(3)^x

Hence, the function of the graph is y = 4(3)^x

[tex]4\sqrt{576}=4\sqrt{2^6\cdot3^2}[/tex]

Answer:

D. f(x) = -|x+4| +3

The graph is flipped over the x-axis (facing down) so there's a negative sign in front of the function. It's shifted to the left 4 units so it'll be |x+4|. Finally, it's shifted up 3 units so it'll be +3 outside of the absolute bracket.

NOTE: if there's a change to the x value then it's inside the bracket or parenthesis, if there's a change to the y value then it's outside of the bracket or parenthesis

Answer:

54 refrigerators

Step-by-step explanation:

In order to find the amount of refrigerators this month, we can do it in one of 2 ways.

The easier way is to multiply 45 by 1.20:

(45)(1.20) = 54

1.20 represents a 120%. This is because 45 refrigerators is 100% of last month, and Simon repaired 20% more, so 100 + 20 = 120.

The next way would be to multiply 45 by 0.20, and then add it to 45.

(45)(0.20) = 9

45 + 9 = 54

Both of the ways result in 54. So, Simon repaired 54 refrigerators this month.
