Answer:
Step-by-step explanation:
This is exponential, of the form
where a is the initial amount and b is the growth/decay rate. If Ginny begins the study with 1200 frogs in the population, our a value is 1200.
If the population is decreasing 3% per year, it is decreasing 100% - 3% = 97% which, as a decimal, is .97. Our exponential function, then, is
The reflection shown in the picture is an example of what's called a <em>rigid transformation</em>, one that doesn't deform the original shape in any way. Rigid transformations preserve lengths and angles, which means that the measure of some angle ∠A is going to be equivalent to the measure of the corresponding transformed angle ∠A'
Here, we see that the only response which represents that correspondence is the last one: m∠BCA = m∠B'C'A'
Si= PTR/100
18 = (3*300*t)/100
18 = 9t
t = 2

Answer:
I think it’s B but I’m sorry if wrong
Step-by-step explanation:
Answer:
68
Step-by-step explanation:
8 x 40 = 320
9 x 28 = 252
320 - 252 = 68
