Answer:

10m.

Step-by-step explanation:

Add up all the areas of the running path and then you can reach to the answer. I got 10m and most probably it should be that only.

What is the argument of -5\sqrt{3}+ 5i?
Shtirlitz [24]

Answer:

150 degrees

Step-by-step explanation:

Graphing the complex number we see the angle terminates in the second quadrant. This means the argument, the angle, will be between 90 degrees and 180 degrees.

So if we create a right triangle with that point after graphing it. We see the height of that triangle is 5 because that is the imaginary part. The base of that triangle has length 5\sqrt{3}. The problem is this doesn't give us any part of the angle we want, but it does give us the complementary of the part of the angle that is in second quadrant.

Let's find the complementary angle.

So the opposite side of the complementary angle is 5.

The adjacent side of the complementary angle is 5\sqrt{3}.

\tan(\theta)=\frac{5}{5\sqrt{3}}

\tan(\theta)=\frac{1}{\sqrt{3}}

\theta=\tan^{-1}(\frac{1}{\sqrt{3}})

\theta=30

So 90-30=60.

The answer therefore 60+90=150.

Trigonometric Identity help​
vovikov84 [41]

Answer:

sin\pi/4 * sin\pi/6 = 1/2 *(cos \pi/12 - cos 5\pi/12)

Step-by-step explanation:

Formula:- sinX sinY = (1/2) [ cos (X - Y) - cos (X + Y) ]

sin(π/4)sin(π/6)

= (1/2)[cos(π/4 - π/6) - cos(π/4 + π/6)]

= (1/2)[cos(3π/12 - 2π/12) - cos(3π/12 + 2π/12)]

= (1/2)[cos(π/12) - cos(5π/12)]

C-53.62 times however many she bought.

so c-(53.62x)

because you are taking how much money she spent and subracting it from how much she had
