Answer:
760772
Step-by-step explanation:
Given that the population of city Z was 420,000 in the year 2000.
The population is projected to grow at a constant rate of 2 percent per year,
We have to find the closest to the projected population of city Z in the year 2030
Since growing at 2% per year treating 2000 as year 0 we can say
where t is the no of years lapsed after 2000.
So at the year 2030, t = 30
Population at th eyear 2030
= 
the projected population of city Z in the year 2030 is 760772
The answer is C, y=10x^2-100x+254
Answer:
Step-by-step explanation:
First term (a) = 7
common difference (d) = 10- 7 = 3
Now
General term
tn = a + (n - 1)d
= 7 + ( n - 1)3
First, subtract 90° from 180°, since 180<span>° is the sum of all the angles in a triangle.
180 - 90 = 90</span><span>°.
Now, we can really just test out different sets of numbers in a 2:7 ratio until we find two that have a sum of 90</span><span>°.
If you look closely, 2 + 7 is 9. So, using that logic, multiplying 2:7 by 10 would get you 20</span>° and 70°, which have a sum of 90<span>°.
So the measures of the missing 2 angles is 20</span>° and 70<span>°.
