To find the answer, see if the point is going to the left or to the right. If it is going to the left, it is less than. If it is going to the right it is greater than. Next find if the point is closed (shaded in) or open (not shaded in). If it is closed, it is equal to, if it is open, it is not equal to. Ex: Closed to the right - Greater than or equal to.
1) x is less than -7
2) x is less than or equal to 4.5
3) x is greater than -5
4) x is greater than 1.5
Answer:
That would be sina.
Step-by-step explanation:
sin(a+b) = sinacosb + cosasinb
sin(a-b) = sinacosb - cosasinb
Adding we get sin(a+b) + sin(a-b) = 2sinaccosb
so sinacosb = 1/2sin(a+b) + sin(a-b)
The volume of the <em>oblate</em> spheroid is approximately equal to 75.398 cubic feet.
<h3>What is the volume of an oblate spheroid?</h3>
In this problem we have the shape of an ellipse centered at origin, whose vertex form is shown below:
x² / a² + y² / b² = 1 (1)
Where a, b are the lengths of the semiaxes, in feet.
An <em>oblate</em> spheroid is generated by revolving half of the ellipse about the y-axis. <em>Oblate</em> spheroids are a kind of ellipse:
x² / a² + y² / b² + z² / a² = 1 (2)
Where a, b, c are the lengths of the semiaxes, in feet.
And the volume of the <em>oblate</em> spheroid is:
V = (4 / 3) · π · a² · b (3)
If we know that a = 3 ft, b = 2 ft, then the volume of the oblate spheroid is:
V = (4 / 3) · π · (3 ft)² · (2 ft)
V ≈ 75.398 ft³
The volume of the <em>oblate</em> spheroid is approximately equal to 75.398 cubic feet.
