What is the speed of a baseball that travels 49 meters in 2.4 seconds
kotykmax [81]

Answer:

Speed of baseball =20.417m/s

Step-by-step explanation:

Speed of a object is the total distance traveled per unit total time taken to cover that distance.

SPEED=\frac{DISTANCE}{TIME}

Given:

             Distance= 49 meter          Time =2.4 seconds

                                    Speed = \frac{49}{2.4}

                                               =  \frac{490}{24}

       Speed of the baseball   =20.417m/s

The speed of baseball is 20.417m/s

Solve log base 6 (x-6) - log base 6 (x + 4) = 2
Ray Of Light [21]

Answer:

no solutions

Step-by-step explanation:

Since the two terms have the same base, we are able to use the rule for subtracting logarithms:

log_{b}(x) - log_{b}(y) = log_{b}(\frac{x}{y} )

Therefore, the equation can be written as:

log_{6}(\frac{x-6}{x+4} )=2

By using the definition of a logarithm we can say that:

\frac{x-6}{x+4} = 6^{2}\\\frac{x-6}{x+4} = 36\\x -6 = 36x+144\\35x = -150\\x =-\frac{30}{7}

When plugging this solution in, you find that the term log_{6}(x-6) has x-6 evaluate to a number less than 0. This is not included in the domain of log functions, so -\frac{30}{7} is not a valid solution. This means that there are no solutions.

The measure of RST can be represented by the expression (6x + 12)°.
Valentin [98]

Answer:

The measure of angle RST is 120\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m -----> equation A

m -----> equation B

equate equation A and equation B

(6x+12)\°=78\°+(3x-12)\°

6x-3x=78\°-24\°

3x=54\°

x=18\°

The measure of angle RST is equal to

m
