Help me out ffgggggggffccc
Aleksandr [31]

Answer:

72 units

Step-by-step explanation:

There are two ways to solve the problems.

Count graphically, horizontally there are 9 units, vertically there are 8 units in the rectangle.  So the area is 9*8 = 72 units.

Alternatively, check the difference between two adjacent vertices,

1. between (4,-3) and (4,5), the difference is (0,8), or 8 units.

2. between (4,5) and (-5,5), the difference is (9,0), or 9 units.

So again, the area of the square is 8*9=72 units.

John uses 2/5 cup of orange juice for every 1/3 cup of pineapple juice to make a fruit punch. Write the number of cups of orange
user100 [1]
Answer : 1 1/5
Step by step explanation :
2/5 orange = 1/3 pineapple
There are multiple ways to go about with this problem, but let’s just go with one of the simplest : Multiplying by the same thing on both sides.
How do we get from 1/3 to 1? We multiply by 3. So, to find how many cups of orange juice we use we need to multiply by 3 too.
2/5 times 3 = 6/5
6/5 = 1 and 1/5
So 1 and 1/5 is the answers, have a great day, and mark brainliest if possible!

Math question ^^^ please help

(\frac{g}{f})(3)=\frac{-13}{21}\\

2/3 will not be included in the domain of g/f

Step-by-step explanation:

Given functions are:

g(x) =-2x^2+5\\f(x)=9x-6

We have to calculate (f/g)(x) first

The steps will be as follows:

(\frac{g}{f})(x)=\frac{g(x)}{f(x)}

Putting the values of functions

(\frac{g}{f})(x)=\frac{-2x^2+5}{9x-6}\\We\ have\ to\ find\ the\ value\ of\ (\frac{g}{f})(x)\ at\ 3\\So,\\(\frac{g}{f})(3)=\frac{-2(3)^2+5}{9(3)-6}\\(\frac{g}{f})(3)=\frac{-2(9)+5}{27-6}\\(\frac{g}{f})(3)=\frac{-18+5}{27-6}\\(\frac{g}{f})(3)=\frac{-13}{21}

Domain of g/f:

(\frac{g}{f})(x)=\frac{-2x^2+5}{9x-6}

The function will be undefined if the denominator is zero.

To find the domain we will put the denominator equal to zero

So,

9x-6=0\\Adding\ 6\ on\ both\ sides\\9x-6+6=0+6\\9x=6\\Dividing\ both\ sides\ by\ 9\\\frac{9x}{9}=\frac{6}{9}\\x=\frac{2}{3}

Hence, the function will be undefined on x=2/3 so 2/3 will not be included in the domain of (f/g)(x)

<u>Answer:</u>

(\frac{g}{f})(3)=\frac{-13}{21}\\

2/3 will not be included in the domain of g/f
