What is the value of x?
SSSSS [86.1K]
All angles in a triangle add up to 180

180 = 9 + 15 + 2x - 1 + 3x

180 = 24 - 1 + 2x + 3x

180 = 23 + 5x

180 - 23 = 5x

157 = 5x

Divide both sides by 5

X = 31.4 or 157/5

Alexandra [31]
45 million * 2^{4} = 45million * 16 = 720million

Or you can use 
y=Ae^{kt}
A is equal to 45 million
To find the rate, k, we can plug in:
90million=45million*e^{k*1}&#10;
2=e^{k}
k=ln(2)
y=4.5*10^{7}*e^{t *ln2}
Knowing that t = 4
y = 4.5*10^{7}*e^{ln(2)*4}&#10;
y = 720 million
