Answer:
9
Step-by-step explanation:
Plug in 2 for x
You should get f(2)=(2+1)^2
Add 2+1 inside the parenthesis to get 3
Finally do (3)^2 to get 9
<h2>Ex 5</h2>
Simply multiply the equation by 6, in order to get rid of the denominators:
<h2>Ex 6</h2>
We have to rearrange the equation in the form
So that 
is the radius, and 
will be the diamater. We have to complete the squares: rewrite the equation as
You can see that 
is the beginning of 
Similarly, 
is the beginning of 
So, if we add 16 and 9 to both sides, the equation becomes
So, now we know that 
, and thus the radius is 13, so the diameter is 26.
Answer:
a) 2 x 10^3
b) 5 x 10^-6
Step-by-step explanation:
Here is a set of numbers , 10,10,10,10,11,12,13,15,17,find the mode, the median , the mean b there is a mistake in the set of nu
Georgia [21]
First, find the mode, median, and mean of the given set of numbers.
<u>Mode</u>
The mode is the number that shows up frequently within the given set. In this case, it will be 10, as it shows up 4 times, 3 times more than any other number.
Mode: 10
~
<u>Median</u>
The median is the number that is in the middle of the given set. In this case, there are 9 numbers, and so the 5th given number is your median:
10 , 10 , 10 , 10 , 11 , 12 , 13 , 15 , 17
Median: 11
~
<u>Mean</u>
The mean is combining all numbers within the given set and dividing by the amount of numbers in that said set:
(10 + 10 + 10 + 10 + 11 + 12 + 13 + 15 + 17)/9 = 108/9 = 12
Mean: 12
