The solution to the problem is as follows:
<span>√28 = √(4 * 7) = √4 * √7 = 2√7.
</span>
<span>√64 = 8
</span>
Therefore, √28 + √64 = <span>2√7. + 8

Hi!
I’d use Pythagora’s theorem here. If PR is 6, PQ is also 6. PQO is a right angle.
OQ^2=6.8^2 - 6^2
OQ^2=46.24 - 36
OQ^2=10.24
OQ= sqrt 10.24
OQ=3.2
Answer:
c. 60.9%
Step-by-step explanation:
Given:
The probability P that a person responds to an advertisement can be modeled by the function:
where 
represents number of days since the advertisement first appeared.
To find the probability that a person has responded after 20 days.
Solution:
In order to find the probability that a person has responded after 20 days, we will plugin 
in the formula given.
We have:
Plugging in
Thus, probability 
after 20 days = 0.6094
The probability in percentage can be given = 
= 60.9%
This one is going to i
hope this helped
