Answer:

29 Minutes

Step-by-step explanation:

The original speed is given in miles per hour (like a car), but the answer is asking for miles per minute, so we must convert the speed into miles per minute first. To do this, we set up this equation: \frac{10.1 miles\ }{1 hour}x\frac{1}{60minutes} which equals  \frac{0.168333333miles}{minute}. We can then divide the desired number of miles by the speed in miles per minute. Here is the eqaution for this \frac{4.9miles}{\frac{0.168333333miles}{1minute} }. The miles cancel and you are just left with 29.1 minutes after you divide 4.9 by 0.168333333. Hope this helps!

1+1=3 proof<br> needs step by step explanation
Vsevolod [243]

Answer:

1+1=3, See explenation

Step-by-step explanation:

1+1=2 but thats basically 2.1 because whole numbers are boring, but 2.1 is basically 2.2 because we want it as an even number, but 2.2 is basically 2.3 because 2.3 is the luckiest number, which is basically 2.5 if you think about it because 2.3 looks like 2/3 and two thirds can't be a whole (which is why we say 3/3 instead of 2/3) and 2.5 rounded up is 3. So thats how 1+1=3

Answer:

r = 1/2

c1 = 3/4

c2 = 27/64

c3 = 405/1408

Step-by-step explanation:

Find the solution of 4x2y′′−4x2y′+y=0,x>04x2y″−4x2y′+y=0,x>0 of the form y1=xr(1+c1x+c2x2+c3x3+⋯)

r = 1/2

c1 = 3/4

c2 = 27/64

c3 = 405/1408

The solution is attached.

Find an expression for f−1(x), if f(x) = 5 − 2x
Lesechka [4]

Answer:

f^{-1}(x) = \frac{5-x}{2}

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject

y = 5 - 2x ( add 2x to both sides )

2x + y = 5 ( subtract y from both sides )

2x = 5 - y ( divide both sides by 2 )

x = \frac{5-y}{2}

Change y back into terms of x

f^{-1} (x) = \frac{5-x}{2}
