Answer:
B
Step-by-step explanation:
'r' and 's' are legs and 't' is the hypotenuse
The Pythagorean Theorem takes the sum of the legs, squared, and sets them equal to the hypotenuse squared.
So in this problem we could start with:
r² + 25² = 27²
r² = 27² - 25²
to get 'r' by itself we take its square root, and what we do to one side of an equation we must also do to the other side, so:
r =
Answer:
The initial population size is of 58.
The population size of the specie after t years is given by:
Step-by-step explanation:
Population size of the specie:
The population size of the specie after t years is given by:
Initial population size
This is P when , that is,
. So
Rounding to the nearest number, 58
The initial population size is of 58.
Answer:
You need at least 125$ so it would be 5x is larger or equal to 125
When solving for x divide both sides by 5
125 / 5 = 25
x = 25
