The time it takes for an object stopped from a certain speed can be modeled by the equationt=1/2 square root v, where v is the speed of object in meters per second. if it takes 3 seconds for the object to stop, what is the speed of object in meters per second?

Answers

Given: 
t = 1/2 √v
v = speed of object meters per second

t = 3 seconds

3 = 1/2 √v
3 * 2 = √v
6 = √v
6² = √v²
36 meters = v

v = 36 meters per second

So I need help with this math problem​

You would solve this problem by using Pythagorean Theorem. This theorem states a^2+b^2=c^2. C is ALWAYS the hypotenuse. We would have to solve for the smaller triangle first. It would look something like this.
3^2+b^2=5^2
9+b^2=25
b^2=16
b=4
Therefore, the missing side to the small triangle is 4. Now, we can solve for the hypotenuse of the bigger triangle,
4^2+7^2=c^2
16+49=c^2
65=c^2
Side z is approximately equal to 8.

Solve the following equation for A. Be sure to take into account whether a letter iscapitalized or not.
4 = gA

Using trigonometry property, the best option is B.

What is trigonometry?

Trigonometry deals with "the relationship between the sides and the angles of triangles".

According to the question,

[tan x + cot x] (sin x + cos x) = 1

[(sin x)/(cos x)+(cos x)/(sin x) ] (sin x cos x) = 1                  [tan x = (sin x)/(cos x) and cot x = (cos x)/(sin x)]

(sin x)/(cos x) (sin x cos x) + (cos x)/(sin x)(sin x cos x) =1    

sin^(2)x +cos^(2)x = 1                                [By cancellation law]

By the Pythagoras theorem, sin^(2)x +cos^(2)x = 1 .

Hence, using trigonometry property, the best option is B.
