If you count 60 animals of a certain species in a study of a national park and the rate of decay for this species is 3.5% per year, what will the population of that species be after 10 years?

42 animals

Step-by-step explanation:

The formula for Exponential decay is given as

y = a (1 - r)^t

Where

y = Population after time t

a = Initial population or size = 60 animals

r = rate of decay = 3.5 % per year = 0.035

t = Time = 10 years

Hence,

y = 60 × (1 - 0.035)¹⁰

y = 60 × 0.7002822742

y = 42.016936449 animals

Approximately = 42 animals

Therefore, the population of that species be after 10 years is 42 animals

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
