Two angles are complementray, one angle is 10 degree greater then the angle. how many degrees are in each angle.

1 answer:

7 0

Complementary means they add up to 90.

Split 90 in half. 45,45
Decrease one half by 5, and increase the other by 5
40,50
The angles are 40 and 50 degrees

The correct equation is P(t) = Po*e^(kt). Please enclose "kt" inside parentheses and use the " ^ " symbol to indicate exponentiation.

"k" is the growth constant, which here is 0.017. "t" is the number of yeasrs. P(7) is the population after 7 years. Po is the initial population, which in this case is 91 million.

The initial value, when t = 0, is 91 million.

After 7 years, the population, P(7), was P(7) = (91 million)*e^(0.017*7). This evaluates to P(7) = (91 million)*(1.070) = 96 million

AD = DB = AB/2 = 6
$cd = \sqrt{{bc}^{2} - {db}^{2} } \\ cd = \sqrt{64} \\ cd = 8$
