Given log4(3) =0.7925 and log4(5) =1.1610, use log properties to find log4(300).
Ede4ka [16]

Answer:

4.1145

Step-by-step explanation:

You can use the following formula to solve this kind of problems,

log_{a}(b)  +  log_{a}(c)  =  log_{a}(bc)

So, let's start of with log4_(300). Since the question have already gave log4_(3) =0.7925 and log4_(5) =1.1610. It means that you have to split the 300 into the simplest form where almost all of the numbers are 3 and 5.

log_{4}(300)  =  log_{4}(4 \times 5 \times 3 \times 5)  \\  =  log_{4}(4)  + log_{4}(5)  + log_{4}(3)  + log_{4}(5)  \\   = 1 + 1.1610 + 0.7925 + 1.1610 \\  = 4.1145

From where Kiana is standing, she must look up at a 50° angle to see the top of a building. If she backs up 50 feet, she will ne
Morgarella [4.7K]
For this case, what we must do is solve the following system of equations:
 tan (50) = h / x
 tan (40) = h / (x + 50)
 Solving the system we have:
 (x + 50) * tan (40) = h
 (x) * tan (50) = h
 Matching:
 (x + 50) * tan (40) = (x) * tan (50)
 Rewriting:
 x (tan (50) - tan (40)) = 50 * tan (40)
 x = 50 * tan (40) / (tan (50) - tan (40))
 x = 118.9692621
 Substituting:
 h = (x) * tan (50)
 h = (118.9692621) * tan (50)
 h = 141.7820455
 Answer:
 
The height of the building is:
 
h = 141.7820455 ft

On Friday, a local hamburger shop sold a combined total of 387 hamburgers and cheeseburgers. The number of cheeseburgers sold wa
ruslelena [56]
Let the number of hamburgers sold be "h" and the number of cheeseburgers be "2h" as it was two time as the humbugers .form equation frome it '2h+h=387".comp the like terms which gives you 3h=387 divide each side by 3 which gives you h=129 which is equal to the number hambyrgers .multiply 129 by 2 to get the number of cheeseburgers which is 258

What is the slope of the line that contains the points (-2,7) and (2,3)
Ludmilka [50]

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =3\\y_{1} =7\\x_{2} =2\\x_{1} =-2

^^^Plug these numbers into the formula for slope...

\frac{3-7}{2 - (-2)}

\frac{-4}{4} -------------------> Simplifies to -1

                                                ^^^This is your slope

Hope this helped!
