If g(x) = 4 square root of x then g(45) is

Answers

Hi,

So we have g(x) = 4√(x). We're looking for g(45). Think of it like this: whatever number is in the place of x in g(x), just place that number AS x.

Therefore, we have :
g(45) = 4√(45) ⇒ (4) × (√(45)) ⇒ (4)(3√(5)) = 12√(5).

Your literature class will read 4 novels this year, chosen by class vote from a list of 7 possible books offered by the teacher.a) How many different ways could the course unfold, given that it probably matters what order you read the books in?
b) How many different choices of books could the class make?
a) The number of different ways the course could unfold is

Answers

Answer:

a) 840 different ways

b) 35 different choices of books

Step-by-step explanation:

We know that our literature class will read a total of 4 novels this year.

All novels chosen by class vote from a list of 7 possible books offered by the teacher.

Wherever we have an experiment $''N''$ which is formed by sub - experiments that can occurred in $m_(1),m_(2),...,m_(n)$ ways, the total number of ways in which the whole experiment $''N''$ can be developed is :

$m_(1)$ x $m_(2)$ x ... x $m_(n)$

Then, for a) if it matters what order we read the books in, the total number of different ways could the course unfold is :

$(7).(6).(5).(4)=840$ (I)

Because for the first book there are 7 different choices. Now, given that we choose the first book, we only have 6 different choices for the second one.

Continuing with the idea, we deduce the equation (I).

For item b) :

Wherever we have $''n''$ different objects and we want to find the ways that we can choose $''r''$ objects from that group, we need to use the combinatorial number.

We define the combinatorial number as :

$nCr=\left(\begin{array}{c}n&r\end{array}\right)=(n!)/(r!(n-r)!)$

Then, if we apply this to the problem, the total different choices of books if we want 4 novels voting from a total of 7 possible books is :

$7C4=(7!)/(4!(7-4)!)=35$

a) 840 different ways

b) 35 different choices of books

Final answer:

The number of different ways the course could unfold is 210, and the number of different choices of books the class could make is 35.

Explanation:

The number of different ways the course could unfold is equal to the number of permutations of the 4 books chosen from the list of 7. This can be calculated using the formula for permutations: P(n, r) = n! / (n - r)!. In this case, n = 7 (the number of books) and r = 4 (the number of books chosen). Using the formula, we get P(7, 4) = 7! / (7 - 4)! = 7! / 3! = 7 imes 6 imes 5 = 210.

The number of different choices of books the class could make is equal to the number of combinations of the 4 books chosen from the list of 7. This can be calculated using the formula for combinations: C(n, r) = n! / (r! (n - r)!). In this case, n = 7 (the number of books) and r = 4 (the number of books chosen). Using the formula, we get C(7, 4) = 7! / (4! (7 - 4)!) = 7! / (4! imes 3!) = (7 imes 6 imes 5) / (4 imes 3 imes 2) = 35.

131 is what percent 2,400,000?

Answers

Let the percentage be 'x.'
$(x)/(100)$ *2,400,000=131 (x percentage of 2,400,000 is 131).
$(x)/(100)$ = $(131)/(2400000)$
x= $(131*100)/(2400000)$
Therefore, x=13100/2400000
x=131/24000
If you want to further convert it into decimals,
x=0.005458333333.....
Therefore, 131 is 131/24000 or 0.005458333333........% of 2,400,000.

Let the percent be x.

According to question,

x / 100 * 2400000 = 131

or, 2400000x = 13100

Thus, x = 13100/2400000

= 0.005 %

Thus, 131 is 0.005 % of 2400000

Why is math so hard?

Answers

because its supposed to be to make us suffer

I wouldn't consider math hard it is just a challenge and sometimes more complex that you have to dig a little deeper to find the answer it won't always be right there. I have to be honest that I am not a fan of math but I learned that I need math in my life because it is everywhere. Remember that math is like building blocks it starts off in kindergarten with adding then subtracting, multiplying, dividing. It continues on with your life. You just need to work with it and soon it won't be as complicated.
