Answer:
1st blank question -269
Second blank question -9
Third blank question -8
Step-by-step explanation:
b=+19=-250 reverse effect 250+19 -269+19=250
-3x-9= 27 negative negative equals positive therfore is 27
8u=-64 8x-8 equal -64

Step-by-step explanation:
Polar coordinates are represented as: , where 'r' is the length (or magnitude) of the line, and '' is the angle measured from the positive x-axis.
in our case:
to covert the polar to cartesian:
we can plug in our values:
the Cartesian coordinates are:
(b) to convert (x,y) = (6.06,-3.5)
we'll use the pythagoras theorem to find 'r'
the angle can be found by:
to convert radians to degrees:
writing in polar coordinates:
Answer:
Likely! You are likely to get a total of 14 if you roll 2 fair numbers.
For this case we must calculate the surface area of the container to know the amount of paint that Ernie must use.
We have then:
A = pi * r ^ 2 + 2 * pi * r * h
Where,
r: cylinder radius
h: cylinder height
Substituting values:
A = 3.14 * (3/2) ^ 2 + 2 * 3.14 * (3/2) * 18
A = 176.625 in ^ 2
Answer:
The amount of paint needed is:
A = 176.625 in ^ 2
