You have an angle of elevation of 3 degrees and you're 2000 ft from base of 30 story building. 
<span>Draw a picture of this. Then tan(3) = ht of bldg/2000 </span>
<span>I get a height of 104.82 ft rounded to 2 dp. </span>


<span>5. Ok. use the Pythagorean Theorem here to find the hypotenuse of the right triangle </span>
<span>hypt = sqrt(50^2 + 9^2) </span>
<span>Now sine of the angle of elevation is 50/hypt. = 0.984 or 0.98 to 2 dp.</span>

Find the​ mean, median, and mode of the​ data, if possible. If any of these measures cannot be found or a measure does not repre
Contact [7]

Answer:

1. Median = 10.1

2. A. The median represents the center.

3. D. The​ mode(s) can't represent the center because it​ (they) is​(are) not a data value.

Step-by-step explanation:

Mean of a sample = sum of the samples/no of the samples

Samples in increasing order:

9.8

9.8

9.9

10.1

10.4

10.6

11.1

Mode is the sample with highest frequency.

Median is the middle entry of the data.

Mean = (9.8 + 9.8 + 9.9 + 10.1 + 10.4 + 10.6 + 11.1)/7

= 717/7

= 10.243

Median = 10.1

Mode = 9.8 because it has the highest frequency of 2

Annual sales for a company are $125,000 and are increasing at a rate of 8% per year. Use an exponential function to find the ann
xxTIMURxx [149]

Answer:

sales after 5 years is $183666

Step-by-step explanation:

exponential function standard form:

a=P(1+r)^t

where p=principal(starting amount)(125,000)

r=rate of change(0.08)

t=time(5)

so

a=125,000(1+0.08)^5

a=125,000(1.08)^5

a=125,000(1.46)

a=183666
