Which equation is the Gizmo using to find the x coordinates

wlad13 [49]

Answer:

The correct answer is C. $(0,10)$ .

Step-by-step explanation:

The polar coordinates are defined in terms of r and θ, where r is the distance of the point from the origin and θ is the angle made with the positive x-axis.

To convert from Polar Coordinates (r, θ) to Cartesian Coordinates (x, y) apply the following conversion formulas:

$x = r\cos \theta \\y = r\sin \theta$

We know that $r=10$ and $\theta = 0.5\pi$

So, the cartesian coordinates are,

$x=10\cos \left(0.5\pi \right)=10\cos \left(\frac{1}{2}\pi \right)=10\cos \left(\frac{\pi }{2}\right)\\\\\mathrm{Use\:the\:following\:trivial\:identity}:\quad \cos \left(\frac{\pi }{2}\right)=0\\\\x=10\cdot \:0\\x=10$

$y=10\sin \left(0.5\pi \right)=10\sin \left(\frac{1}{2}\pi \right)=10\sin \left(\frac{\pi }{2}\right)\\\\\mathrm{Use\:the\:following\:trivial\:identity}:\quad \sin \left(\frac{\pi }{2}\right)=1\\\\y= 10$

The correct answer is C. $(0,10)$ .

Sixty percent of the students in class are boys. If 12 of the students in the class are girls ,what is the total number of stude

Arlecino [84]

So 60% of the class are boys, but we're given the number of girl students. We know that the remaining 40% of the class are girls, which equals 12 students. To find out the total number of students in the class we can divide the number we're given into 10%, which we can then multiply to give 100%.

So 40% of the class equals 12 students, we divide by 4 to give 10%, so 12 ÷ 4 = 3. So 10% of the total class is 3 students, we times by 10 to find 100% of the class, so 3 x 10 = 30 students.
