Answer:
identify is verified, see work below.
Step-by-step explanation:
Verify following identity
2gh/sin^2θ = 2gh sec^2θ/sec^2θ-1
use identity 1+tan^2(θ) = sec^2(θ) on denominator of right-hand-side
right-hand side
= 2gh sec^2(θ) / (sec^2(θ)-1)
= 2gh sec^2(θ) / (tan^2(θ))
= 2gh sec^2(θ) * (cos^2(θ) / sin^2(θ) ) [note: sec^2(θ) = 1/cos^2(θ)]
= 2gh * 1 / sin^2(θ)
= 2gh / sin^2(θ)
= left-hand side
Therefore identify is verified.
<u><em>Answers:</em></u>
a. 
miles/day
b. 14 miles
<u><em>Explanation:</em></u>
<u>Part a:</u>
We are given that they paddled a total distance of 14 miles for 3 days. To get the distance paddled each day, we will divide the total paddled distance by the number of days
<u>This is done as follows:</u>
Distance paddled each day = miles/day
<u>Part b:</u>
<u>Now, we are given that:</u>
<u>i. They went half their daily distance:</u>
Daily distance = 
miles/day
<u>ii. They extended the trip twice as many days</u>
Number of days = 2 × 3 = 6 days
The total distance paddled will be equivalent to the product of the distance paddled each day and the total number of days
<u>This means that:</u>
Total distance = 
miles
Hope this helps :)
The correct answer is the second one: ±√15/3
Explan ation:
You have the quadratic equation <span>3x^2−10=−5. Then you must clear the variable "x" as below:
</span><span>
3x^2−10=−5</span>
<span> 3x^2=−5+10
</span><span>3x^2=5
</span><span>x^2=5/3
x=</span>±√(5/3)
When you multipy the numerator and the denominator by 3 for simplify the result, you obtain:
x=±√(5x3/3x3)
x=±√(15/3²)
When you simplify, you have:
x=±√15/3
The answer is 9. I notice you keep asking the same questions over and over again, all simple and trivial answers. Please either stop trolling or consult a parent or teacher to help you!
