Answer:
x=4
Step-by-step explanation:
f(x) = (x-2)^5 +3
Let f(x) = 35
35 = (x-2)^5 +3
Subtract 3 from each side
35-3 = (x-2)^5 +3-3
32 = (x-2)^5
Take the fifth root of each side
32 ^ (1/5) = (x-2)^5^ 1/5
2 = x-2
Add 2 to each side
2 +2 = x-2+2
4 =x
<span>To find a missing number in a data set given the mean of the data set, count the total number of data points in the data set, including the missing number, and multiply the mean by this total number. Next, add together the known numbers in the data set. Finally, take the difference of the two numbers just calculated.</span>
Answer:
r = - 6
Step-by-step explanation:
Given
6r + 7 = 13 + 7r ( collect terms in r on the left and numbers on the right )
Subtract 7r from both sides
- r + 7 = 13 ( subtract 7 from both sides )
- r = 6 ( multiply both sides by - 1 )
r = - 6
Answer:
=x3y5+x5y
Step-by-step explanation:
The equation really told me the answer
Looking at the values given for Flouride (mg), we have the lowest value of 0.4 and the highest value of 7.1
The axis should start at 0 and the least number it should go up to is 8
Looking at the values in between 0.4 and 7.1, we have 1.6, 2.5, 3.1, 4.5 and 6.8
Ideally, we want the scale that makes it easier to read this values, the smaller the scale is the better.
Answer: 0 to 8 with intervals of 0.2 (C)
