We have that
(r, ∅)----------> (-7, <span>5 pi/3)
we know that
</span>5 pi/3--------> 300°-----------> -60°
To convert polar cordinates in rectangular one with use the following formula:
x=r*cos ∅------> x=-7*cos -60°-------> x=-7*(1/2)------> x=-7/2
y=r*sin ∅-------> y=-7*sin -60-------> y=-7*(-√3)/2----> y=7√3/2
the answer is the option
D) ordered pair negative 7 divided by 2 comma 7 square root 3 divided by 2
Answer:
the missing side of the rectangle should be twelve
Step-by-step explanation:
All you've got to do is multiply both 13 and 20 by 5 so the fractions would be 65/100. Since you're trying to convert it into a decimal, you would move the decimal point 2 units to the right. This will result in the answer : 0.65.
Changing 13/20 would be 0.65
A=(pi)(radius^2)
radius=4 for small circular cake
radius=12 for large circular cake
Area of small circular cake=16pi
Area of big circular cake=144pi
144pi/16pi=9 times bigger than small circular cake.
NO, 9 TIMES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
If the equation is arranged in point-slope form we get:
y = 2x - 11.
The y-intercept is at (0, -11).
Therefore a point on the line is (0, -11).
