Answer:
x + 2 < 42
Step-by-step explanation:
Minimum height for Crazy cart = 42 inches
x = height last summer
Number if inches grown since last summer = 2
Height now = x + 2 is still not yet up to 42 inches because he is not yet tall enough to get on crazy carts ride.
Representing as an inequality :
x + 2 < 42
(x)+(x+1)+(x+2)=-36
3x+3=-36
3x=-39
x=-13
The numbers are -13, -12, -11
6 divided by
is the same as 6/1 multiplied by 9/8, which gives us 7 as the whole answer. therefore, I think number 1 and 4 are the correct selections
ANSWER TO QUESTION 1
The given function is

The partial derivative of f with respect to x means we are treating y as a constant. The first derivative is

and the second derivative with respect to x is,

ANSWER TO QUESTION 2
The given function is

The partial derivative of f with respect to y means we are treating x as a constant. The first derivative is

and the second derivative with respect to y is

ANSWER TO QUESTION 3
Our first mixed partial is

We need to differentiate

again. But this time with respect to y.
Since this is a product of two functions of y, we apply the product rule of differentiation to obtain,


ANSWER TO QUESTION 4
The second mixed partial is

We need to differentiate

again. But this time with respect to x.
Since this is a product of two functions of x, we apply the product rule of differentiation to obtain,


Hence,
