Find the rectangular coordinates of the point with the polar coordinates (8, 3 divided by 2 pi).
ludmilkaskok [199]
(r, theta)= (8, 3/2 pi)
r=(x^2 +y^2)^(1/2)
theta= 3/2 pi
x= r(costheta)
y=r(sintheta)
x=8(cos(3/2 pi))
y=8(sin(3/2 pi))
x=8(0)
y=8(-1)
x=0
y=-8
r=((-8)^2+(0)^2)^(1/2)
r=(64+0)^(1/2)
r=8
rectangular coordinates= (0,-8)

Vlada [557]

Answer:

$1.43

Step-by-step explanation:

To find how much one roll of paper towels cost, we have to divide the total purchase ($20.02) by the number of paper towel rolls (14).

20.02 ÷ 14

= $1.43

One paper towel roll costs $1.43

Q 1. The area of a certain rectangle is 1 m².What is the area of a triangle that was cut off from that rectangle along a line co
Radda [10]

Answer:

0.125 m²

Step-by-step explanation:

The area of a rectangle is the product of its length and breadth. Therefore:

area of the rectangle = length (l) × breadth (b) = 1 m².

l × b = 1

A triangle is cut off from that rectangle along a line connecting the midpoints of two adjacent sides, therefore the base of the triangle = length of rectangle/2 and the height of triangle = breadth of rectangle/2.

Area of triangle = 1/2(base × height) = \frac{1}{2}*\frac{l}{2}*\frac{b}{2}=\frac{1}{8}lb

since lb = 1:

Area of triangle = \frac{1}{8}*1=0.125m^2
