Someone ! 1. a person at ground level measures the angle of elevation to the top of a building to be 74°. if at this point the person is 34 feet away from the base of the building, then how tall is the building?round to the tenths place. show work/steps and provide units with your answer. 2. in right triangle pqr, p and q are complementary angles. the value of sin q is 9/ . what is the value of cos p? a.9/41 b.41/9 c.40/41 d/41/40

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
