Answer:

Option D is right

Step-by-step explanation:

Given are two graphs. The first one is given as

$f(x) = log_{2} x\\$

The second one equation we have to find out.

Option A given as

$g(x) =\frac{1}{2} log_{2} x$ is having x intercept as

(0,1/2). But our g(x) has x intercept as 1. Hence not correct.

Option B: $g(x) = log_{2} \frac{1}{2} x$

This has x intercept as (0,2). Since does not match with g(x) not correct

OPtion C:

$g(x) = log_{2} 2x$

Here x intercept = 1 matches with ours.

Also g(2) = 2, twice as that of original f(x)

Hence option C is not right

Option D is only right because x intercept should be 1 and also when x=4 y=2(log 4 to base 2)

The distance between Columbus,Ohio and New York City is about 560 miles how many hours would it take the train to travel between

sergey [27]

Since the distance is 560 miles and the bus goes 268 miles per hour, the answer can be given as:
If 268=1 hour
560=?
560/268*1 hour =2(rounded to nearest ones)
Therefore it will take the train approximately 2 hours to travel between both cities.

How do you do question b?

notsponge [240]

Part (b)

We use the result of part (a) and plug in (x,y) = (0,0). This is directly from the initial condition y(0) = 0.

$\arcsin(4y) = x^2 + C\\\\\arcsin(4*0) = (0)^2 + C\\\\\arcsin(0) = C\\\\0 = C\\\\C = 0\\\\$

-----------------

This means,

$\arcsin(4y) = x^2 + C\\\\\arcsin(4y) = x^2 + 0\\\\\arcsin(4y) = x^2\\\\4y = \sin(x^2)\\\\y = \frac{1}{4}\sin(x^2)\\\\$

is the solution with the initial condition y(0) = 0.
