The tan angle opposite to opposite side and the hypotenuse is the ratio of opposite side to the hypotenuse side.

The distance between the building and Diana after walking is,17.6 ft.

The tan angle opposite to opposite side and the hypotenuse is the ratio of opposite side to the hypotenuse side.

Given information-

The height of the building is 130 ft.

Initial angle of the Diana with the building when she looks up, is 37 degrees.

The angle when, Diana walks forward looking to the top of the building changes to 40°.

Suppose Diana was x meter away, from the building when the angle was 37 degrees.

The  Diana walks forward and her angle looking to the top of the building changes to 40°.

As tan angle is the ratio of opposite side to the hypotenuse. Therefore

[tex]\begin{aligned}\tan (37^o)&=\dfrac{130}{x}\\x&=172.5\\\end[/tex]

Now suppose the distance covered by Diana after walking is y ft. Thus again by the right angle property,

[tex]y=\dfrac{130}{\tan40}\\y=154.9[/tex]

As the initial distance from building is 172.5 fr and distance covered by Diana is 154.9 ft. Thus the distance between the building and Diana after walking is,

[tex]d=172.5-154.9\\d=17.6\rm ft[/tex]

Hence the distance between the building and Diana after walking is,17.6 ft.

FIGURE F... I just got it right on iready

The figure that showcases the rotation of figure E in the image attached below is figure F.

A rotation is a planar transformation that rotates each and every point of a figure around a fixed reference point at a defined angle and direction. The fixed point is known as the rotational center. 

Rotating figures entails revolving them around a central axis and at certain degrees. The figures themselves usually remain the same, but their location in space will shift.

Geometric Sequence formula for general term:

an = a1(r^n-1)

a1 = 4 × (-5)^1-1

a1 = 4

r = -5

Summation formula for geometric sequence :

Sn = a1 ( 1 - r^n / 1 - r )

...take n from the top of the summation.

= 4 ( 1 -(-5)^6 / 1 -(-5)

= -10416.

Answer:

  7

Step-by-step explanation:

The first term is 2. The common ratio is -6/2 = -3. The n-th term is ...

  an = a1·r^(n -1)

Using the last term value, we have ...

  1458 = 2·(-3)^(n -1)

  729 = (-3)^(n -1)

Taking logarithms, we have ...

  log(729) = (n -1)·log(|-3|)

  n = 1 +log(729)/log(3) = 1 +6 = 7

The series is 7 terms long.

Answer:

y = [tex]\frac{6}{5}[/tex] x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{6}{5}[/tex] , then

y = [tex]\frac{6}{5}[/tex] x + c ← is the partial equation

To find c substitute (5, 1 ) into the partial equation

1 = 6 + c ⇒ c = 1 - 6 = - 5

y = [tex]\frac{6}{5}[/tex] x - 5 ← equation of line

(θ) = 84°

Step-by-step explanation:

Given: sin(θ)=cos(6)

Find: value of θ

Computation: sin(θ)=cos(6)

We know that  cos(90-a) = sin(a)

So, sin(θ)=cos(90-84)   sin(θ)=sin(84)  

So, (θ) = 84°

Answer:

5%

Step-by-step explanation:

Let the interest rate be x100

So we have for simple interest: x100×$2600=$390

This is the same as: ddddddddddx×$2600100=$390

x×$2600100=$390

Divide both sides by $26.

x×$26$26=$390$26

x×1=$390$26

x=15

But x is from x100

The % symbol is like a unit of measurement and one that is worth 1100

So 15100d→d15×1100d→d15×%→15%

But this is over 3 years so the annual interest rate is d15%3=5%

50 = x^2

[tex]\sqrt{50}[/tex] = x,   5[tex]\sqrt{2}[/tex]

x = approximately 7.07

Answer:

Exact: SQRT 50

Approx: 7.07

Step-by-step explanation:

you take both of the 5s and square them.

So 5*5=25 and 5*5 is 25. Since the right angle is opposite the side you are trying to find you add those together to get 50. Then you take the SQRT of 50 because you are trying to solve for x via the pythagorean theorem.

So the exact is SQRT 50

and the approx is 7.07

See below for answers and explanations for each part (along with attached graph)

Step-by-step explanation:

Recall the equation [tex]f(x)=asin(bx+c)+d[/tex] where [tex]a[/tex] is the amplitude, [tex]\frac{2\pi}{b}[/tex] is the period, [tex]-\frac{c}{b}[/tex] is the phase/vertical shift, and [tex]d[/tex] is the midline

If you review the attached graph, you will see that when [tex]t=15[/tex], then the bottle will reach its lowest height of 8 feet

I hope these explanations and the attached graph help you understand sinusoidal functions better! Please mark this answer brainliest if you found this answer helpful!

a) The amplitude of the function is 4 feet.

b) The function that represents the situation is [tex]y(t) = 10 +4\cdot \sin \frac{\pi\cdot t}{10}[/tex].

c) The bottle will take 15 seconds to reach its lowest height.

a) The amplitude ([tex]A[/tex]), in feet, is equal to the difference between highest and lowest point ([tex]y_{max}[/tex], [tex]y_{min}[/tex]), in feet, divided by 2. The period ([tex]T[/tex]), in seconds, is the time taken by the bottle to complete one cycle. In this case, the period is the time between two maxima. Hence, we proceed to determine each variable:

[tex]A = \frac{14\,ft-6\,ft}{2}[/tex]

[tex]A = 4\,ft[/tex]

The amplitude of the function is 4 feet. [tex]\blacksquare[/tex]

The period of the function is 20 seconds. [tex]\blacksquare[/tex]

b) The function that represents the situation is based on this model:

[tex]y(t) = y_{o} + A \cdot \sin \frac{2\pi\cdot t}{T}[/tex] (1)

Where:

If we know that [tex]A = 4\,ft[/tex], [tex]y_{o} = 10\,ft[/tex] and [tex]T = 20\,s[/tex], then the function that represents the situation is:

[tex]y(t) = 10 +4\cdot \sin \frac{\pi\cdot t}{10}[/tex] (2)

The function that represents the situation is [tex]y(t) = 10 +4\cdot \sin \frac{\pi\cdot t}{10}[/tex]. [tex]\blacksquare[/tex]

c) With the help of a graphic tool, we graph the function in time. According to the image, the bottle will take 15 seconds to reach its lowest height. [tex]\blacksquare[/tex]
