Answer:

A.

Step-by-step explanation:

A is incorrect. The definition of logarithms is that if log_{a}b=c, then a^c=b.

The variables are in the wrong place. The correct answer should be:

log_{p}N=b, p^b=N

B is correct since as ln(x)=log_{e}(x). Thus, e^y=x

C is correct because the square root of anything is simply that thing to the one-half power.

D is also correct as this is <em>the </em>definition of a logarithm.

<h3>Answer: Choice A</h3>

\log_p N = b is not the same as b^p = N

The base of the log is p, while the base of the exponential is b. The two don't match. If it said \log_p N = b \text{ is the same as } p^b = N then it would be a valid statement since the bases are both p.

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

Extra info:

Choice B is a valid statement because Ln is a natural log with base 'e'

Choice C is valid as any square root is really something to the 1/2 power

Choice D is valid for similar reasons mentioned earlier

Major league baseball's fastest recorded pitch is 105 miles per hours. The distance between the pitcher's mound and home plate i
blsea [12.9K]

Answer:

0.4 sec

Step-by-step explanation:

Remember that

1 mile=5,280 feet

1 foot=12 inches

1 hour=3,600 seconds

Let

s -----> the speed in ft/sec

d ----> the distance in ft

t -----> the time in sec

s=d/t

Solve for t

t=d/s

step 1

Convert  miles/hour to ft/sec

105 mi/h=105(5,280/3,600)=154 ft/sec

Convert 60 ft 6 in to ft

60 ft 6 in=60+(6/12)=60.5 ft

step 2

Find the time

t=d/s

we have

s=154 ft/sec

d=60.5 ft

substitute

t=60.5/154

t=0.39 sec

Round to the nearest tenth

t=0.4 sec
