Answer:
The answer to your question is: 24 561 104 bacteria
Step-by-step explanation:
every 16 minutes bacteria population double
There are 6140276 bacteria at 9:15 AM
estimate bacteria at 9:47
First calculate the minutes : 47 - 15 = 32 minutes
and 32 / 16 = 2
then 2 times the bacteria population double
So,
first time = 6140276 x 2 = 1 2280552 bacteria
second time = 1 2280552 x 2 = 24561104 bacteria
Answer: The angle of elevation would be 36.87 degrees (approximately)
Step-by-step explanation: Please refer to the attached diagram for details
The 30-foot ladder reaches a point in the building which is point A. The height at which the ladder touches the building is 18 feet (that is, the height of the building, line AC. The angle of elevation from the ground is at angle B, the angle which the ladder forms with the ground.
So we have a right angled triangle ABC, with two sides and a reference angle B. To find angle B, we shall apply the trigonometric ratio;
SinB = opposite/hypotenuse
SinB = 18/30
SinB = 0.6
By use of a calculator or table of values
B = 36.8698
Approximately, angle B = 36.87 degrees
Answer: x=-40
Step-by-step explanation: Solve for x by simplifying both sides of the equation then isolate the variable!
