Take out the GCF of 75 and 12 which is 3:-
= 3(25t^2 + 4)
That's it
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)

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
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;

Substituting into the equation, we have;


Volume of sphere = 1.371886933 * 10^-7 cubic meters.
To the nearest tenth;
Volume of sphere = 1.3 * 10^-7 cubic meters.
