Answer:

I think it's letter C.

Step-by-step explanation:

not sure correct me if I'm wrong.

We are going to multiply the fraction 1/2, to the power of 3.

This means that:

Therefore:

[tex]\bf{\left(\dfrac{1}{2}\right)^{3}=\dfrac{1\times1\times1}{2\times2\times2}=\dfrac{1}{8} }[/tex]

Therefore, the answer of the fraction (1/2)^3, is equal to 1/8.

The length of the arc of the circle will be 19.8 ft.

The arc of the circle is the distance of the circumference of the circle formed sector of the circle at a particular angle.

The formula for the length of the arc of the circle will be given as:-

Arc = Angle x radius

We have Angle = 1.1 radians Radius = 18ft

Arc = 1.1 x 18

Arc = 19.8 ft.

Therefore the length of the arc of the circle will be 19.8 ft.

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 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:

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:

Step-by-step explanation:

Answer:

x = 16

Step-by-step explanation:

 SR = ST ⇒ Two sides are equal. So, ΔSRT is an isosceles triangle.

The angles opposite to equal sides are equal.

  ⇒  ∠STR  = ∠R

       ∠STR = 4x - 28

Linear pair: If a ray stands on a line, then the adjacent angles are supplementary and they are called linear pair

∠STR + ∠STU = 180°    {linear pair}

4x - 28 + 9x = 180

4x + 9x - 28  = 180      {Combine like terms}

       13x- 28 = 180

Add 28 to both the sides

          13x    = 180 + 28

           13x  = 208

Divide both sides by 13

              x = 208/13

  [tex]\sf \boxed{x = 16}[/tex]

Answer:

x = 16

Step-by-step explanation:

since SR = ST , then Δ RST is isosceles with the 2 base angles congruent.

∠ STR = ∠ SRT = 4x - 28

∠ STR and ∠ STU are a linear pair and sum to 180° , that is

9x + 4x - 28 = 180

13x - 28 = 180 ( add 28 to both sides )

13x = 208 ( divide both sides by 13 )

x = 16

Answer:

  (a)  The mold growth rate of the banana bread was three times the mold growth rate of the whole wheat bread

Step-by-step explanation:

The equation for exponential growth can be written in the form ...

  f(t) = a·b^t

where a is the initial value, and b is the growth factor for time period t. The growth factor is related to the growth rate by ...

  b = 1 +r . . . . . where r is the growth rate in time period t

__

The equation for the area of mold on the banana bread is given as ...

  B(t) = 20·1.06^t

Comparing to our generic equation, we see ...

The growth rate of the mold on the banana bread is given as 0.06 = 6% per week.

__

We are given some values of t and area that we can use to find the growth rate of mold on the whole wheat bread.

  W(1) = 40.8 = a·b^1

  W(4) = 43.30 = a·b^4

The ratio is ...

  W(4)/W(1) = (a·b^4)/(a·b^1) = b^3 = 43.30/40.8

Then the value of b can be found to be ...

  b = ∛(43.30/40.8) ≈ 1.02002 ≈ 1 + 0.02

The growth rate of mold on the whole wheat bread is about 0.02 = 2% per week.

__

The mold growth rate on the banana bread compared to that on the whole wheat bread is ...

  (banana bread growth rate)/(whole wheat bread growth rate) = 6%/2% = 3

We can conclude ...

  The mold growth rate of the banana bread was three times the mold growth rate of the whole wheat bread

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.

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 ...

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
