Answer:
60 degrees.
Step-by-step explanation:
BC is parallel to the x axis (because B and C have the same y-coordinate).
Slope of AB is 3/√3 = √3
so the angle AB makes with the axis = angle it makes with BC
= arctan(√3)
= 60 degrees.
Answer:
D
Step-by-step explanation:
The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.
The entry in the 
row (start counting rows from 0) and 
column (start counting columns from 0) of Pascal's triangle is denoted by
Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.
Hence,
Answer:
D.
Step-by-step explanation:
0.72 = 72%
So that being the case, his car's value decreased by 72%
This is my very own step-step solution:
Step 1:
<span>Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : </span>
<span> 42*x^5*y^4-((-7*x^3*y)*(b))=0
</span>
Step 2:<span>Equation at the end of step 1 :</span><span>
((42•(x5))•(y4))-((0-(7x3•y))•b) = 0
</span>
Step 3:Pulling out like terms :
<span> 42x5y4 + 7x3yb</span> = <span> 7x3y • (6x2y3 + b)</span>
The correct is: 7x3y • (6x2y3 + b) = 0 <span>
</span>
Quick Side Note:
<span>Binomial can not be factored as the difference of two perfect cubes
</span>
I hope this helps a little!
Hope you have a great day!
