What is the polar graph of r = 2cos3(theta) and a characteristic?

1 answer:

4 0

we are given the function r=2cos(3θ)
from the pythagorean theorem, r2=x2+y2
from the polar definition, x=rcos3θ x/r = cos3θ y=rsin3θ r=2x/r r2=2x x2+y2−2x=0.

This equation represents a parabola

Andy promises opie that he will give him 5000 upon his graduation from college at mayberry u. How much must andy invest today to

san4es73 [151]

Answer: Andy should invest RS. 2784.19 for 12 years .

Step-by-step explanation:

Since we have given that

Amount = Rs. 5000

Time = 12 years

Rate of interest = 5%

So, We need to find the sum:

Using "Compound interest" , we get :

$A=P(1+r)^t\\\\5000=P(1+0.05)^{12}\\\\5000=P(1.05)^{12}\\\\\dfrac{5000}{1.05^{12}}=P\\\\2784.19=P$

Hence, Andy should invest RS. 2784.19 for 12 years .

Consider the line y=-x-3.

kicyunya [14]

Answer:

perp: 1

y - 5 = x -6

y = x - 1

parallel: -1

y - 5 = -(x - 6)

y - 5 = -x + 6

y = -x + 11

A quadrilateral has no pairs of parallel sides. What shape could it be? ( im not accepting rhombus or trapezium as an answer ).

natali 33 [55]

Answer: The answer is a parallelogram! I hope this helps you!!

Step-by-step explanation: If only one pair of opposite sides is required to be parallel, the shape is a trapezoid. A trapezoid, in which the non-parallel sides are equal in length, is called isosceles.
