Answer:

Step-by-step explanation:

ok, so this is an infinitly repeating function, so you can write it as:

sqrt(12-x)

Although, x is also equal to sqrt(12-x), so

x = sqrt(12-x), and

x^2 = 12-x

x^2-12+x = 0

now just apply the quadratic formula and you're good

hope i helped :D

Simplify this PLEASE

Advocard [28]

Answer:

$\frac{12a-14b}{21}$

Step-by-step explanation:

Express the 2 fractions with a common denominator of 21

multiply numerator/denominator of first fraction by 3

multiply numerator/denominator of second fraction by 7

$\frac{4a(3)}{7(3)}$ - $\frac{2b(7)}{3(7)}$

= $\frac{12a}{21}$ - $\frac{14b}{21}$

= $\frac{12a-14b}{21}$

If the mean of the data set is 35 apples find the number of apples on the Granny Smith tree

alisha [4.7K]

Answer:

$N=\frac{\sum x_{i} }{35}$

Step-by-step explanation:

Given

The mean of the data set is 35 apples.
Let's call $N$ the number of apples.

The means is defined as the quotient between the sum of all elements and the total number.

Mathematically, it would be defined as

$x=\frac{\sum x_{i} }{N}$

But, we know that the mean is equal to 35.

$35=\frac{\sum x_{i} }{N}$

Then, we solve for $N$

$N=\frac{\sum x_{i} }{35}$

As you can see, the total number of apples depends on the sum of all elements of the data set.

For example, if the sum of all elements is 700, the total number of apples would be

$N=\frac{700}{35}=200$

Therefore, the expression that represents the total number of apples is

$N=\frac{\sum x_{i} }{35}$

Solve 5x -c = k for x

inysia [295]

x = $\frac{k+c}{5}$

isolate 5x by adding c to both sides of the equation

5x = k + c ( divide both sides by 5 )

x = $\frac{k+c}{5}$
