Answer:
Step-by-step explanation:
Recursive formula
tn = t_n-1 / 4
t2 = t1 / 4
t2 = 10240
t1 = 10240 / 4 = 2560
Explicit formula
tn = 10240 / 4^(n-1)
t4 = 10240 / 4^(4 - 1)
t4 = 10240 / 4^3
t4 = 10240 / 64
t4 = 160
t8 = 10240 / 4^7
t8 = 0,625

the area of a rectangular room is 285 sq feet. The width of the room is 19 feet. What is the length of the room?
Answers
Answer:
15 feet
Step-by-step explanation:
The area of a rectangle is length × width = area. We're given the area as 285 square feet, and the width as 19 feet.
length × 19 = 285Now, we divide 285 by 19.
285/1915Thus, the answer is 15 feet.

I WILL GIVE BRAINLIEST Suppose that is $1200 initially invested in an account at a fixed interest rate, compounded continuously. Suppose also that, after six years, the amount of money in the account is $1431 . Find the interest rate per year.
Write your answer as a percentage. Do not round any intermediate computations, and round your percentage to the nearest hundredth.
Answers
Answer:
so we know that we're starting with $2500. We know it's compound a continuous interest, and they tell us that the interest rate is 6% and we want to find the amount of time it's going to take for it to basically double because it says 5000. So we divide both sides by five Excuse me by 2500 and we end up with E to the 0.6 T is equal to two. We can take the natural log of both sides mhm, and we can use a log of a powers at this point. Oh, 60 can come down in front with log of a power and lo and behold Oh, my goodness, Ellen up e is one. So all we need to do to solve is divide both sides by 0.6, and that will give us our time. We need to round that off to the nearest 10th of a year. So Ln of two divided by 20.6 11.6 11.55 But to the nearest Tampa would be 11.6 years. And we are done. Mm hmm.

Answers
Answer:
1.395 hours
Step-by-step explanation:
Time is proportional to distance, and inversely proportional to speed. The relationship is ...
time = distance/speed
For the given speed and distance, the time is ...
time = (60 mi)/(43 mi/h) = 60/43 h ≈ 1.395 h
At 43 mph, it will take about 1.395 hours to travel 60 miles.

During natural selection, organisms with harmful traits are less likely to successfully reproduce than organisms with beneficial traits. Neutral traits don’t improve or hurt an organism’s chances for survival. So, they tend to persist in populations when environmental conditions are stable. If the environment changes, neutral traits could become harmful or beneficial depending on the situation. In year 1, a population of rain forest plants has the following distribution: 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves. You will simulate three years of this population: year 1, year 5, and year 10. How will the trait distribution most likely change over this time?.
Answers
Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
Natural selectionNatural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.
All of these mechanisms can make a population evolve, or change its genetic makeup over generations.
But there's one mechanism of evolution that's a bit more famous than the others, and that's natural selection. What makes natural selection so special? Out of all the mechanisms of evolution, it's the only one that can consistently make populations adapted, or better-suited for their environment, over time.
You may have already seen natural selection as part of Darwin’s theory of evolution. In this article, we will dive deeper – in fact, deeper than Darwin himself could go. We will examine natural selection at the level of population genetics, in terms of allele, genotype, and phenotype frequencies.

Find the area of this shape in two different ways.
Answers
Answer:
10 meters²
Step-by-step explanation:
Method 1 ~
This method adds the triangle with the two rectangles.
----------------------------------------------------------------------------------------------------------
First find the area of the largest rectangle ~
Width = 4 meters - 2 meters = 2 meters
Length = 3 meters
Area = Width × Length = 2 meters × 3 meters = 6 meters²
Then find the area of the second rectangle ~
Width = 1 meter
Length = 2 meters
Area = Width × Length = 1 meter × 2 meters = 2 meters²
Then find the area of the triangle ~
Base = 3 meters - 1 meter = 2 meters
Height = 2 meters
Area = [tex]\frac{bh}{2}[/tex] = [tex]\frac{2*2}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2 meters²
Finally, add the triangle and the two rectangles together ~
6 meters² + 2 meters² + 2 meters² = 10 meters²
Method 2 ~
This method subtracts the triangle from the whole rectangle.
----------------------------------------------------------------------------------------------------------
First find the area of the rectangle ~
Width = 3 meters
Length = 4 meters
Area = Width × Length = 3 meters × 4 meters = 12 meters²
Then find the area of the triangle ~
Base = 3 meters - 1 meter = 2 meters
Height = 2 meters
Area = [tex]\frac{bh}{2}[/tex] = [tex]\frac{2*2}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2 meters²
Lastly, subtract the triangle with the rectangle ~
12 meters² - 2 meters² = 10 meters²
