What is the value of the x-coordinate of point A?
ycow [4]

Answer:

D.) cos(6π/5)

Step-by-step explanation:

In a unit circle, cosine is defined as x-coordinate and sine is defined as y-coordinate.

This is because cosine is defined as x/r but since it’s a unit circle, r = 1 therefore, cosine = x,

Sine is defined as y/r but it’s a unit circle so sine = y.

Therefore, we ignore choices with sine.

Next, since this π/5 angle is in the third quadrant. π/5 is supposed to be in the first quadrant so to convert from first quadrant angle or reference angle to the third quadrant angle or opposite side, add the reference angle or π/5 by π.

Therefore, π/5 + π = π/5 + 5π/5

= 6π/5

Since we want to find x-coordinate which is cosine, therefore.

The answer is cos(6π/5)

Write an equation in standard form of the parabola that has the same shape as the graph of f(x)=4x^2 or g(x)=−4x^2​, but with th
Alex777 [14]
\bf y=\pm(x-{{ h}})^2+{{ k}}\qquad\qquad  vertex\ ({{ h}},{{ k}})\\\\
-----------------------------\\\\
f(x)=x^2\iff y=(x-0)^2+0\\\\\\ f(x)=-x^2\iff y=-(x-0)^2+0

if the maximum, or minimum is at 5, that simply means y = 5 and x =-2 for the vertex of that parabola

so just set h= -2 and k = 5 there, that's the parabola's equation

The diameter, D, of a sphere is 6.4 mm. Calculate the sphere's volume, V.
SCORPION-xisa [38]

Answer:

Volume of sphere = 1.3 * 10^-7 cubic meters.

Step-by-step explanation:

Given the following data;

Diameter, D = 6.4 mm to meters = 6.4/1000 = 0.0064 meters.

But, Radius = diameter/2

Radius = 0.0064/2 = 0.0032 meters.

π = 3.14

To determine the volume of sphere, we would use the formula;

Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3}

Substituting into the equation, we have;

V = \frac {4}{3} * 3.14 * 0.0032^{3}

V =  4.186666667 * 3.2768 * 10^{-8}

Volume of sphere = 1.371886933 * 10^-7 cubic meters.

To the nearest tenth;

Volume of sphere = 1.3 * 10^-7 cubic meters.
