A bird caught a fish on the waters surface and flew in a straight line diagonal to the water for 100 yards. Then, it dropped the
ozzi

Answer:

1. B

2. B

Step-by-step explanation:

** Attached picture of the situation

The bird caught the fish at point A, flew until B (which is 100 yds away, dropped the fish at C (which is horizontally 50 yards from A).

1.

We want the angle that the bird creates with the water (horizontal). It is angle BAC. With respect to the right triangle, we can say that we know "hypotenuse" and "adjacent" side to angle BAC. cosine relates hypotenuse and adjacent, thus we can write:

Cos(BAC)=\frac{50}{100}\\Cos(BAC)=\frac{1}{2}\\BAC=Cos^{-1}(\frac{1}{2})\\BAC=60

correct answer is B

2.

Here, we want to find the distance (length) of segment BC. With respect to the angle BAC (we found to be 60), we can say BC is "opposite". We know hypotenuse to be 100. So let's use sine, since sine is ratio of opposite to hypotenuse. Thus, we can write:

Sin(BAC)=\frac{BC}{100}\\Sin(60)=\frac{BC}{100}\\BC=Sin(60)*100\\BC=86.6

correct answer is B

What is the solution of 2|2x-1|-8=18?
Maurinko [17]

Solve for |2x-1|:

2|2x-1|-8=18\implies2|2x-1|=26\implies|2x-1|=13

Now if 2x-1\ge0, we have |2x-1|=2x-1 and

2x-1=13\implies2x=14\implies x=7

On the other hand, if 2x-1, then |2x-1|=-(2x-1)=1-2x and

1-2x=13\implies-2x=12\implies x=-6

Student scientific calculator 3×10^5 is displayed as 3 EE 5 in that case how was the panic of 80,000 and 5000 be displayed on Th
faltersainse [42]
Hello,
We know that
3×10^5= 3 EE 5
Change 80,000 to the scientific notation
8×10^4
Doing the same like 3×10^5, I can get 8 EE 4
Change 5000 to the scientific notation
5×10^3
Then it will appeared as 5 EE 3. Hope it help!
