For the answer to the question above,
In 1 minute, bison runs 3520 feet
In 60 minutes, the bison would run
3520*60 feet
211200 feet per hour.
These are equivalent to;
40 miles per hour since 1 mile is equivalent to 5280 feet.
The bison is faster by 10 miles per hour
Then If you convert the bison's speed to mph you get that it can run at speeds up to 40 mph.

I got this by seeing how many feet that they run in one hour so 3520 x 60 is 211200 which divided by 5280 is 40 mph.

I hope my answer helped.

Anu drinks 2 cups of water each day. Jan drinks twice as much water as Anu.How many fluid ounces does Jan drink?
frosja888 [35]
Simple,

first find out how many fluid ounces there are in 1 cup

1 cup=8 fluid ounces

That means for Anu:

2*8=16

Anu has drunk 16 fluid ounces.

Now, Jan, we know that she drinks 2x (twice) as much as Anu...

So,

4 cups:

4*8=32

Thus, it means that Jan has drunk 32 fluid ounces.

Use linear approximation to approximate 25.3‾‾‾‾√ as follows. Let f(x)=x√. The equation of the tangent line to f(x) at x=25 can
loris [4]

Answer:

Approximation f(25.3)=5.03 (real value=5.0299)

The approximation can be written as f(x)=0.1x+2.5

Step-by-step explanation:

We have to approximate f(25.3)=\sqrt{25.3} with a linear function.

To approximate a function, we can use the Taylor series.

f(x)=\sum_1^{\infty} \frac{f^{(n)}(a)}{n!}(x-a)^n

The point a should be a point where the value of f(a) is known or easy to calculate.

In this case, the appropiate value for a is a=25.

Then we calculate the Taylor series with a number of terms needed to make a linear estimation.

f(x)\approx f(a)+\frac{f'(a)}{1!}(x-a)

The value of f'(a) needs the first derivate:

f'(x)=\frac{1}{2\sqrt{x}}\\\\f'(a)=f'(25)=\frac{1}{2\sqrt{25}}=\frac{1}{2*5}=\frac{1}{10}

Then

f(x)\approx f(25)+\frac{1}{10}(x-25)=\sqrt{25} +\frac{1}{10}(x-25)\\\\f(x)\approx 5+\frac{1}{10}(x-25)

We evaluate for x=25.3

f(25.3)\approx 5+\frac{1}{10}(25.3-25)\\\\f(25.3)\approx 5+\frac{1}{10}(0.3)=5.03

If we rearrange the approximation to be in the form mx+b we have:

f(x)\approx 5+\frac{1}{10}(x-25)=5+0.1x-2.5\\\\f(x)\approx 0.1x+2.5

Then, m=0.1 and b=2.5.

When you convert 100ft per second to inches per second will there be more or less than 100 inches
Firlakuza [10]
It would be more than 100 inches because in one foot is 12 inches, so take 100 x 12 = 1200 inches

a system of two linear equations has infinitely many solutions. one of the equations in the system is y-3x=-3.write an equation
Troyanec [42]
The other equation could be 

2y - 6x = -6

Solving:-

y - 3x = -3..........(1)
2y - 6x = -6........(2)
multiplyng the first equation by 2 gives
2y - 6x = -6

so equations (1) and (2) are the same equation
If we graph them they will be the same line 
Every point on that line will be a solution.

So there are infinitely many solutions
