Answer:
10x - 3y = -109 .
Step-by-step explanation:
x^2 + y^2 = 109
Implicit Differentiation:
2x + 2y.y' = 0
y' = -2x/2y = -x/y
So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.
Equation of the tangent:
y - y1 = m(x - x1)
y - 3 = 10/3(x + 10)
y - 3 = 10/3 x + 100/3
3y - 9 = 10x + 100
-109 + 3y = 10x
10x - 3y = -109
Answer:
C) The correlation is most likely a coincidence.
Step-by-step explanation:
By general comprehension of the population and their buying habits, I don't think we can really establish a relation between the sales of computers and the microwaves in a general manner. If the store is located near a university residence and it's September, there might be a link to be done, but in general, no.
It's not like some enters a store and says "Ok, will I buy a microwave or a computer today?". Those are two totally different products, with different clienteles and different needs.
Answer: = 6x + 1
Step-by-step explanation:
Answer:
1) 130°
2) 130°
Step-by-step explanation:
Assuming SR, TU, and PQ are parallel, they would both be 130. (180-50)
30 can go into 54 once because 54/30 = 1.8
