Answer:
B
Step-by-step explanation:
For a relationship to be a function
Each value of x in the domain can only have 1 unique value of y in the range. That is, one-to-one correspondence.
The only relation which meets this criteria is B
Solve the equation for x by finding a
, b
, and c of the quadratic then applying the quadratic formula
Exact form:

<span> The product of two perfect squares is a perfect square.
Proof of Existence:
Suppose a = 2^2 , b = 3^2 [ We have to show that the product of a and b is a perfect square.] then
c^2 = (a^2) (b^2)
= (2^2) (3^2)
= (4)9
= 36
and 36 is a perfect square of 6. This is to be shown and this completes the proof</span>
Answer:
40 days
Step-by-step explanation:
w1*h1*d1=w2*h2*d
15*8*20=10*6*d
2400=60d
d=2400/60
d=40
