Brainliest answer + 60pts!!
Rus_ich [418]

<em>Answer:</em>

y = 100(6.3246^x)

<em>Explanation:</em>

Ao*k^x = A  where  Ao is the initial amt

k = constant factor

x = time in hrs

A = resulting amt

Write an equation from the 1st statement, x = 2 hrs, find k

100 * k^2 = 4000

k^2 = 4000%2F100

k^2 = 40

k = sqrt2840%29

k = 6.3246

The equation :

y = 100(6.3246^x)

Whats the value of x <br><br>A 95<br><br>B 105<br><br>C 75<br><br>D 85​
professor190 [17]

Answer:

D. 85

Step-by-step explanation:

The sum of the interior angles of a triangle is equal to 180. Since we already know 2 of the interior angles of that triangle (40 and 55), we can subtract those two angles from 180 to find x.

180 - 40 - 55 = 85
