Answer:

Time is negative “time” is a method founded by man to record events. ... So to conclude this question, you can give negative time as in countdowns, or past events. But there is no such thing as a negative in a chronological time graph, that starts and ends with positive numbers, unless you consider BC as the negative on the line chart

expression to approximate log a of x for all positive numbers a, b, and x, where a is not equal to 1 and b is not equal to one

amid [387]

Question:

Approximate log base b of x, log_b(x).

Of course x can't be negative, and b > 1.

Answer:

f(x) = (-1/x + 1) / (-1/b + 1)

Step-by-step explanation:

log(1) is zero for any base.

log is strictly increasing.

log_b(b) = 1

As x descends to zero, log(x) diverges to -infinity

Graph of f(x) = (-1/x + 1)/a is reminiscent of log(x), with f(1) = 0.

Find a such that f(b) = 1

1 = f(b) = (-1/b + 1)/a

a = (-1/b + 1)

Substitute for a:

f(x) = (-1/x + 1) / (-1/b + 1)

f(1) = 0

f(b) = (-1/b + 1) / (-1/b + 1) = 1

Gabriella drives her car 320 miles and averages a certain speed. If the average speed has been 6 miles less she could have trave

arsen [322]

Answer:

Her average speed is 48 miles per hour.

Step-by-step explanation:

We solve this question using a system of equations.

The speed equation is:

$s = \frac{d}{t}$

In which s is the speed, d is the distance, and t is the time.

Gabriella drives her car 320 miles and averages a certain speed.

So $d = 320$

Then

$s = \frac{320}{t}$

If the average speed has been 6 miles less she could have traveled only 280 miles in the same length of time.

So, which s - 6, d = 280.

$s - 6 = \frac{280}{t}$

From the first equation:

$s = \frac{320}{t}$

$st = 320$

$t = \frac{320}{s}$

Replacing:

$s - 6 = \frac{280}{t}$

$s - 6 = \frac{280}{\frac{320}{s}}$

$320(s - 6) = 280s$

$320s - 1920 = 280s$

$40s = 1920$

$s = \frac{1920}{40}$

$s = 48$

Her average speed is 48 miles per hour.
