Answer: The answer should be 9.2195
Step-by-step explanation:They tell us the point is 2.9 and they are asking the distance from the origin which is zero. So we can use pythagorean theorem. A²+B²=C² Look at it as a triangle. They have given us A and B, so you can find C² using those information. If you plot the point in the line you know that A=2 and B=9. Using the formula will be 2²+9²=C² ⇒ 4+81=C² ⇒ 85=C². To get rid of the power of 2 in c we have to square both side to cancel it out. C would equal 9.2195
Use the Cosine Rule
q^2 = 20^2 + 30^2 - 2^20*30 cos 15
= 140.89
so q = sqrt 140.89 = 11.9 (answer)
Answer:
60 people
Step-by-step explanation: Multiply 20 by 3 and you will get 60, which is the total combonation of people.

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Given that:
h(t) = 2t² - 5t + 29
The minimum height is at h'(t) = 0, hence:
h'(t) = 4t - 5
4t - 5 = 0
t = 5/4
h(5/4) = 2(5/4)² - 5(5/4) + 29 = 25.875 feet
