Writing the equation that governs this situation:
-3C - (2.5C/hr)x = -18C
Simplifying, -3 - 2.5x = -18, or 3 + 2.5x = 18
Combining like terms: 2.5x = 18-3 = 15
Then x = 15/2.5 = 6. The temp. will reach -18C after 6 hours.
Answer: Reflection across the y axis.
Clockwise rotation
Step-by-step explanation:
Plan A gives you 6% interest compounded annually so after 4 years
$2000 becomes $2000*(1.06)^4 = $2524.95
Plan B gives you 13% annual simple interest so after 4 years
$2000 becomes $2000*(1+0.13*4) = $3040
so Plan B earns more
Given:
The equation of the hyperbola is:
To find:
The the equation which is not an asymptote of the hyperbola.
Solution:
We have,
It can be written as:
Equating denominator and 0, we get
So, the vertical asymptotic is .
The degree of numerator is 0 and the degree of denominator is 1.
Since the degree of numerator is greater that the degree of denominator, therefore the horizontal asymptote is 
and there is no oblique asymptote.
Therefore, 
is not an asymptote of the given hyperbola and the correct option is C.
