Step-by-step explanation:
What grade is this for?
Answer: it takes 5s for each plane to travel their respective distances
Step-by-step explanation:
Let a = speed of plane A
Let b = speed of plane B
b = 55 + a
Time for plane A to fly 4000 miles
= 4000/a
Time for plane B to fly 4275 miles
= 4275/b
Since it takes same amount of time
4000/a = 4275/b
4000b = 4275a-------1
Put b = 55+a in eqn
4000(55+a) = 4275a
220000+4000a = 4275a
275a = 220000
a = 800
b = 55 +800 = 855
Time for plane A to fly 4000 miles
= 4000/800 = 5s
Time for plane B to fly 4275 miles
= 4275/855= 5s
All of the trigonometric functions of an angle θ can be constructed geometrically in terms of a unit circle centered at O. Given that:
Sine function
being
Cosine function
being
We will demonstrate the identity above. First of all, we need to square each equation, so:
Adding these two equations:
But as shown in the figure, using Pythagorean theorem
is always equal to 1, then:
The relation to right triangles is that:
<span>The hypotenuse is always equal to 1
</span>The opposite side is equal to
The adjacent side is equal to
Answer:
the function that is graphed is y=½CSC(x)
Answer:
The slope is 4/5 i dont know unit rate though, hope this helps:)
