It’s not a solution because 5+3 = 8 and 20 is greater than eight but there’s a line under the greater sign which means it’s greater than or equal to and 20 is not equal to 8 (if that makes sense)
<span>Answer: Slope = -4.000/2.000 = -2.000
x-intercept = 2/6 = 1/3 = 0.33333
<span> y-intercept = 2/3 = 0.66667
What I'm trying to show in the graph is:
</span></span>
y tells us how far up the line goes.........
x tells us how far along...........
m is the Slope or Gradient i.e. how steep the line is.........
b is the Y-intercept i.e. where the line crosses the Y axis.......
I really hope this helps ^-^
The polar form of the equation is -2 cosθ
<u>Explanation:</u>
( x + 1 )² + y² = 1
r² = x² + y²
Use x = r cosθ and y = r sinθ
Substitute these variable in x and y
( r cosθ + 1 )² + ( r sinθ )² = 1²
r² cos²θ + 1 + 2 r cosθ + r² sin²θ = 1
r² ( cos²θ + sin²θ ) + 1 + 2 r cosθ = 1
r² + 1 + 2 r cosθ = 1
r² + 2 r cosθ = 0
r² = -2 r cosθ
r = -2 cosθ
Therefore, the polar form of the equation is -2 cosθ
Answer:
"$/km"
Step-by-step explanation:
He wants to model "maintenance cost" with respect to "distance"
Normally,
maintenance cost would be in currency --- dollars, pounds etc.
distance would be in kilometers, miles, meters etc.
We need to find the ratio that has the COST on top and DISTANCE on bottom
Looking at the choices,
We can eliminate 1st and 3rd immediately as it doesn't have COST on top.
That leaves us with
$/km
and
km/$
$ is in fact currency and unit for cost and km is in fact unit for distance. We need the ratio that has $ on top and km on bottom, that's the 2nd option.
So, $/km is the appropriate unit.
