Answer:
613 meters
Step-by-step explanation:
1)
cos(50 degrees)=324/x
x*cos(50 degrees)=324
x=324/cos(50 degrees)
x=around 504.1
2)
cos(35 degrees)=324/x
x*cos(35 degrees)=324
x=324/cos(35 degrees)
x=around 395.5
now lets find the distance in between the two people:
Distance from Shively to the tower
tan(50 degrees)=x/324
x=324*tan(50 degrees)
x= around 386.1
Distance from Sparzak to the tower
tan(35 degrees)=x/324
x=324*tan(35 degrees)
x=around 226.9
total distance=386.1+226.9=613 meters
Answer:
3.44 ounces in each bowl
Step-by-step explanation:
15.34 ounces total
15.34-1.58=13.76 (ounces in all 4 bowls)
13.76/4=3.44 ounces in each bowl
Write <u>two functions</u> that <u>describes</u> the <u>decrease of the population</u> after <u>t years.</u>
1. In one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. Then after t years the number of orngutans will be

2. In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. Then after t years the number of orngutans will be

3. Equate right sides of the equations:

Answer: after 3 years
