Answer:
binomial
Step-by-step explanation:
a monomial has 1 term
a binomial has 2 terms
a trinomial has 3 terms
2x + y has 2 terms and so is a binomial
Y-intercept: Let x = 0. Result: 5x=0, and x= 0. y-intercept is (0,0).
Similarly, x-int. is (0,0) (after going thru the same procedure: set y=0 and find x)
Answer:
option D
Step-by-step explanation:
from the question 10>4-3x
it simply means 10-4>-3x
=6>-3x
x>6/-3
=x>-2
the above statement means that x is greater than -2
For the first one your equation is h(d)=3/7d+5
If d represents the number of days and the question is wanting to know the height after 1 week (7 days) then you would get this equation once 7 is in the place of d
h(d)=3/7(7)+5
When solved you answer is 8 inch.
For the second one your equation is f(x)=75x+250
If x represents the number of weeks and the question is asking how much money Sam will have after 12 weeks then you will get this equation once putting in 12
f(x)=75(12)+250
Once solved you will get the answer $1150
Hope this helps! :)
Answer:
C) The partial derivatives were not evaluated a the point.
D) The answer is not a linear function.
The correct equation for the tangent plane is 
or 
Step-by-step explanation:
The equation of the tangent plane to a surface given by the function 
in a given point 
can be obtained using:
(1)
where 
and 
are the partial derivatives of 
with respect to 
and 
respectively and evaluated at the point .
Therefore we need to find two missing inputs in our problem in order to use equation (1). The 
coordinate and the partial derivatives and . For just evaluating in the given function we obtain 
and the partial derivatives are:
Now, substituting in (1)
Notice that until this point, we obtain the same equation as the student, however, we have not evaluated the partial derivatives and therefore this is not the equation of the plane and this is not a linear function because it contains the terms (
and 
)
For finding the right equation of the tangent plane, let's substitute the values of the partial derivatives evaluated at the given point:
or
