77° is the answer to your question
You can use the <u>determinant</u><u> (square root)</u> of a quadratic equation to determine the number and type of solutions of the equation.
> 0 → 2 real solutions
- if is a perfect square, then rational sol'ns
- if is not a perfect square, then irrational sol'ns
= 0 → 1 real solution (double root)
< 0 → 2 imaginary(complex) solutions
Answer:
yes it does
Step-by-step explanation:
as you can see,
in a function, we don't have more than one y for a x, so here we have one y for each x. then it is
Answer:
81 times the original size
Step-by-step explanation:
AA0ktA=3A0=?=?=25hours=A0ekt
Substitute the values in the formula.
3A0=A0ek⋅25
Solve for k. Divide each side by A0.
3A0A0=e25k
Take the natural log of each side.
ln3=lne25k
Use the power property.
ln3=25klne
Simplify.
ln3=25k
Divide each side by 25.
ln325=k
Approximate the answer.
k≈0.044
We use this rate of growth to predict the number of bacteria there will be in 100 hours.
AA0ktA=3A0=?=ln325=100hours=A0ekt
Substitute in the values.
A=A0eln325⋅100
Evaluate.
A=81A0
At this rate of growth, we can expect the population to be 81 times as large as the original population.
Year one, 59,000 + 11% = 65,490
Year two, 65,490 + 11% = 72,693.90
