Please answer and explain!!!

meriva

When you have f(3), that means X is equal to 3.

The problem states if x <-3 then f(x) would be -2.
If x is between -1 and -3, then f(x) would be 4x.
If x is greater than -1, f(x) would be x^2.

3 is greater then -1, so f(3) would be x^2, now replace x with 3 to get 3^2, which equals 9.

f(3) = 9

If 70% of a number is 42 and 15% of the same number is 9, find 85% of that number.

BigorU [14]

Answer: 51

Step-by-step explanation:

let x be the number.

(70%)x = 42

0.7 x = 42

x = 60

we check 15% x 60 = 0.15 x 60 = 9, which is true.

85% of that number = 85% x 60 = 0.85 x 60 = 51.

Write a intruduction paragraph on comparing and contrasting paper book and ebook please

Vesnalui [34]

You may have heard that traditional paper books are disappearing in favor of those new-fangled electronic books. While e-books have made huge inroads in the publishing industry, I don’t believe that traditional books will ever completely disappear.I grew up reading books as my special pastime. Nothing can compare to sitting by a crackling fire turning the pages of a leather-bound book or lounging at the beach with a good dog-eared paperback while soaking up the sun. Yet, recently, I have turned to e-books for much of my reading. I believe that there is room in my life for both types of books. I believe that while Americans still love paper books, they are reading e-books than ever before and they are reading them on more kinds of devices.

There are 15 technicians and 11 chemists working in a research lab. They need to form a 5 person safety committee. In how many w

Burka [1]

<h2>There are a total 65,780 ways in which the committee can be made of 5 members.</h2>

Step-by-step explanation:

Here, the total number of technicians in the lab = 15

The total number of chemists in the lab = 11

So, the total members in the lab = 15 + 11 = 26

So, there are total 26 eligible candidates in the lab from which committee of 5 people has to be made.

Now, since there is <u>no restrictions</u> on the choice, so the committee can be formed in nay way, such that:

It may or may not have any technician.

It may or may not have may chemists.

So, the number of ways 5 member can randomly be chosen from a committee of 26 people = $^{26} C_5$

$^{26} C_5$ = $^{26} C_5 = \frac{26!}{5! \times 21!} = 65,780$

Hence, there are a total 65,780 ways in which the committee can be made of 5 members.
