Consider the set of points defined by z = 5 cos(theta) + 3i sin(theta).

Mathematics
1 answer:
vitfil [10]3 years ago
4 0

Answer:

This is an ellipse.

Step-by-step explanation:

z=5cos(\theta)+3isin(\theta)

Applying the angle values in intervals of right angles (90°), the resulting set of values for z are:

\theta = 0,90,180,270,360

z=5,3i,-5,-3i,5 (again)

If you look at the plot, you will observe how these values represent points in the xy plain. All of them belong to either the x or the y axis.

The resulting figure for the whole set of values of \theta is in fact an ellipse.

Brrunno [24]

Answer:

Q = 193.27 kg

Step-by-step explanation:

A shopkeeper mixed three quality of pulses weighing 34.650 kg ,68.275 kg and 90.350 kg respectively.

We need to find the total quality of pulse he has. It means, total quality of pulse he has is :

Q = 34.650 + 68.275 +90.350

= 193.27 kg

Hence, he has 193.27 kg pulse.

What is the perimeter, to the nearest hundredth of a unit, of the the
AnnyKZ [126]

Answer:

20.31 units to the nearest hundredth.

Step-by-step explanation:

We need to use the distance formula between the points and find their sum.

D1 = √((2-2^2 + (1+3)^2)  = √16 = 4

D2 =  √(-1-2)^2 + (3-1)^2) = √13

D3 = √(-3+1)^2 + (0-3)^2) =  √13

D4 = √(-3+3)^2 + (-4)^2) = √16 = 4.

D5 = √(-3-2)^2 + (-4+3)^2) = √26.

Perimeter = D1+D2+D3+D4+D5

=  4+√13+√13 + 4 +√26

= 20.31 units.

Can someone help with this please
VladimirAG [237]

Answer:

GH = 9

Step-by-step explanation:

Note:

GI = GH + HI

Plug in the corresponding terms to the corresponding variables:

3x + 8 = (x + 6) + (x + 5)

First, simplify. Combine like terms:

3x + 8 = (2x) + (11)

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 2x and 8 from both sides:

3x (-2x) + 8 (-8) = 2x (-2x) + 11 (-8)

3x - 2x = 11 - 8

x = 3

Plug in 3 for x in the length of GH.

GH  = x + 6

GH = 3 + 6

GH = 9

9 is the numerical length of GH.
