Answer:
50 cm
Step-by-step explanation:
The altitude from the vertex to the base bisects the base and divides the triangle into 2 right triangles.
Using one of the right triangles with legs 8 and 15 , then hypotenuse h is
h² = 8² + 15² = 64 + 225 = 289 ( take the square root of both sides )
h = = 17
The 2 congruent sides of the isosceles triangle are 17 cm
Then the perimeter P is
P = 17 + 17 + 16 = 50 cm
Answer:
15595 bacteria will be present after 13 hours.
Step-by-step explanation:
Continuous population growth:
The continuous population growth model, for the population after t hours, is given by:
In which P(0) is the initial population and r is the growth rate.
Started with 5000 bacteria
This means that
So
After three hours it grew 6500 bacteria:
This means that . We use this to find r.
So
How many bacteria will be present after 13 hours?
This is P(13). So
Rounding to the nearest whole number
15595 bacteria will be present after 13 hours.
