Answer:

Step-by-step explanation:

Just plug in 20 for t:

f(20)=\frac{60*20}{20^2+46}=\frac{1200}{400+46}=\frac{1200}{446}=2.69058

Answer:

\displaystyle 2\frac{154}{223}\:mg. = f(20)

Step-by-step explanation:

\displaystyle \frac{60[20]}{20^2 + 46} = \frac{1200}{400 + 46} = \frac{1200}{446} = 2\frac{154}{223}

I am joyous to assist you anytime.

Given the sequence 2, 5, 8, 11, 14, ..., which term is 59? (Hint: find n.)
____ [38]
N = 3  ( the next number is 3 plus the previous number
 sequence formula = an = 3(n-1) +2

so for term the term that =59

59 = 3(n-1) +2

distribute:
59 = 3n -3+2

59 = 3n -1

60 = 3n
n = 60/3
n = 20

59 is the 20th term

Space Shuttle Marion is observing the launch of a space
Vera_Pavlovna [14]

Using the slope concept, it is found that the shuttle traveled 3.2 miles while Marion was watching.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.

Initially, the angle of elevation is of 16º, with an elevation of 1 mi, hence:

\tan{16^\circ} = \frac{1}{x_1}

x_1 = \frac{1}{\tan{16^\circ}}

x_1 = 3.5

Then, at the end, the angle will be of 74º, with the elevation remaining constant, hence:

\tan{74^\circ} = \frac{1}{x_2}

x_2 = \frac{1}{\tan{74^\circ}}

x_2 = 0.3

The distance is:

d = x_1 - x_2 = 3.5 - 0.3 = 3.2

The shuttle traveled 3.2 miles while Marion was watching.
