Determine an approximate value for y if the coordinate (-0.5387 ,y) is on the unit circle

adoni [48]

Answer:

y = 0.8425 or y = -0.8425

Step-by-step explanation:

All points in the Cartesian coordinate system have an x and y coordinate, defined by two perpendicular measurements.

If the point is on the unit circle, then the radius of the circle is defined to be 1 unit, and the corresponding right triangle follows the Pythagorean Theorem.

$a^2+b^2=c^2$

For a unit circle:

$x^2+y^2=1^2$

Substituting the known value for x, and simplifying...

$(-0.5387)^2+y^2=(1)^2$

$0.29019769+y^2=1$

Subtracting 0.29019769 from both sides to begin to isolate "y"...

$y^2=1-0.29019769$

$y^2=0.70980231$

Applying the square root property...

$\sqrt{y^2}=\pm \sqrt{0.70980231}$

$y=\pm 0.8424976171...$

So, (to 4 decimal places), the y coordinate could be either 0.8425 or -0.8425.

With only the given information, either result is a valid answer.

Find equation of a line that has point ( 1, -2 ) and slope -4

Colt1911 [192]

∵It slop=-4
∴Equation is: y=-4x+b
∵Point (1,-2) in this line
(∴We can substitute x, y to 1, -2)
∴-4×1+b=-2
∴b=2
Equation: y=-4x+2

A solid is formed by adjoining two hemispheres to the ends of a right circular cylinder. The total volume of the solid is 10 cub

lesantik [10]

Answer:

1.619

Step-by-step explanation:

We have the formulas for the volume of the sphere and the cylinder:

Vs = (4/3) * pi * (r ^ 3)

Vc = pi * h * (r ^ 2)

Thus:

(4/3) * pi * (r ^ 3) + pi * h * (r ^ 2) = 10

Now, the formula for the surface area of the cylinder and sphere are:

As = 4 * pi * (r ^ 2)

Ac = 2 * pi * r * h + 2 * pi * r ^ 2

Using this equation for the total surface area of the solid, we can see that as "h" increases, so will the surface area. Therefore, the smallest surface area will occur at h = 0.

Thus:

(4/3) * pi * (r ^ 3) + pi * 0 * (r ^ 2) = 10

(4/3) * pi * (r ^ 3) = 10

r ^ 3 = 4 * 10 / (3 * 3.14)

r ^ 3 = 4.24

r = 1.619

so the radius is 1.619
