Answer:

\sqrt {55} inches

Step-by-step explanation:

Let x inches be the length of one side of the frame. The frame is the square, so all sides have the same lengths.

Use formula A=x^2\ in^2 connecting the area of the square and the side length of the square.

Since the area ofthe square is 55 square inches, we have

x^2 =55\\ \\x=\sqrt {55}\ in

If we looked at a satellite photo at the same scale, could we see any boats on the river? If a 50-foot boat were on the river, h
Dafna11 [192]

Answer:

<em>1. We can't see any boat on the river at this scale.</em>

<em>2. 0.025 inches. We won't be able to see it</em>

<em></em>

Step-by-step explanation:

<em>the beginning of the question states that; according to this map, the driving distance is 3 miles, we're most interested in the graphics at the bottom left, which indicates that 1 inches on the map corresponds to 2,000 ft in real life.</em>

<em />

If 1 inches = 2000 ft,

x inches = 50 ft

we cross multiply to give

2000x ft = 50 ft-inches

x = 50/2000 =<em> 0.025 inches</em>

The mass of a colony of bacteria, in grams, is modeled by the function P given by P(t)=2+5tan^−1.(t/2), where t is measured in d
ira [324]

Answer:

1.21 g/day

Step-by-step explanation:

We are given that

The mass of a colony of bacteria (in (grams) is given by

P(t)=2+5tan^{-1}(\frac{t}{2})

Where t=Time(in days)

Differentiate w.r.t t

P'(t)=5(\frac{1}{1+\frac{t^2}{4}}\times \frac{1}{2})

By using the formula \frac{d(tan^{-1}(x)}{dx}=\frac{1}{1+x^2}

P'(t)=\frac{5}{2}(\frac{4}{4+t^2})

P'(t)=\frac{10}{4+t^2}

We are given P(t)=6

Substitute the value

6=2+5tan^{-1}(\frac{t}{2})

5tan^{-1}(\frac{t}{2})=6-2=4

tan^}{-1}(\frac{t}{2})=\frac{4}{5}

\frac{t}{2}=tan(\frac{4}{5})

t=2tan(\frac{4}{5})

Substitute the value of t

P'(2tan\frac{4}{5})=\frac{10}{4+4tan^2(\frac{4}{5})}

P'(2tan\frac{4}{5})=\frac{10}{4}\times \frac{1}{1+tan^2(\frac{4}{5})}

We know that 1+tan^2\theta=sec^2\theta

Using the formula

P'(2tan(\frac{4}{5})=\frac{5}{2}\times \frac{1}{sec^2(\frac{4}{5})}

P'(2tan\frac{4}{5})=\frac{5}{2}\times cos^2(\frac{4}{5})

By using cos^2x=\frac{1}{sec^2x}

P'(2tan\frac{4}{5})=\frac{5}{2}\times (0.696)^2=1.21g/day

Hence,the instantaneous rate of change of the mass of the colony=1.21g/day

Choose any positive integer. Powers of two here are not very interesting, so choose something else. If the number you have chose
Yakvenalex [24]

Answer:

Step-by-step explanation:

Let the integer be 6 for even and 7 for odd (say)

For 6, we divide by 2, now get 3.  Now we multiply by 3 and add 1 to get 10. Now since 10 is even divide by 5, now multiply by 3 and add 1 to get 16.  Now divide by 2 again by 2 again by 2 again by 2 till we get rid of even numbers.

The result is 1, so multiply by 3 and add 1 we get 4 now divide 2 times by 2 to get 1, thus this result now again repeats after 2 times.

Say if we select off number 3, multiply by 3 and add 1 to get 10 now divide by 5, now repeat the same process as above for 5 until we get 1 and it gets repeated every third time.

Thus whether odd or even after some processes, we get 1 and the process again and again returns to 1.
