Answer:
The answer to your question is: 2nd option is correct.
Step-by-step explanation:
Data
slope = m = -4
Point = (-3, 1)
Formula
(y - y1) = m(x - x1)
y - 1 = -4(x - (-3)) Substitution
Answer:
The first answer is 1.66 Japanese Yin
The second answer is 0.60 U.S. Dollars
Step-by-step explanation:
The ratio of U.S. Dollars (USD) to Japanese Yin (JY) is 3 : 5 -
= USD : JY
= 3 : 5
To find the number of Yin received for 1 Dollar, divide the ratio on both sides by 3 as for 3 Dollars you receive 5 Yin -
= USD : JY
= 3 : 5
= 1 : 5/3
= 1 : 1.66
So, for 1 USD you will receive 1.66 JY
To find the number of Dollars received for 1 Yin, divide the ratio on both sides by 5 as for 5 Yin you receive 3 Dollars -
= USD : JY
= 3 : 5
= 3/5 : 1
= 0.60 : 1
So, for 1 JY you will receive 0.60 USD
Answer:
C. (-2,2π/3)
Step-by-step explanation:
Given:
In the given plane, each line represents angles and the circles shows the radii. Now as full circle is of 360 degrees or 2π and there are 12 straight lines that means
every angle is π/6 apart (30 degrees).
As the given red point is on circle 2, this means the radii, r=2
and Ф=300 degrees or 5π/3
r=(2,5π/3)
but above is not given in the options.
Polar coordinates can have positive or negative theta and also have positive or negative radii. In case of negative radii the polar coordinate moves in opposite direction of the pole.
if we consider r=-2 then we have to move in opposite direction of pole of Ф=300 degrees or 5π/3 is 120 degrees or 2π/3.
hence r=-2 andФ=2π/3
Correct option is C:(-2,2π/3)!
No they do not. Just by looking at the numbers, you can tell they are clearly different. However, if you had 2 expressions, you can evaluate the expressions. But, since you are clearly able to tell the numbers are not the same thing, we do not need to do that for this problem.
