Answer:
No, they aren't similar.
Step-by-step explanation:
<u><em>Let's take the proportionality of their sides to check whether they are similar or not:</em></u>
=> 2 ≠ 3
So, they are not similar.
B because if you multiply .15 and .45 by 100 you get 15% and 45%. 45% is much higher than 15%
Answer:
Step-by-step explanation:
f(x,y)=10-x^2-y^2
To find derivative of z w.r.t. x is treat any other variable as a constant.
dz/dx=0-2x-0
dz/dx=-2x
Evaluating this at (7,-3) gives us dz/dx=-2(7)=-14.
Since this result is negative, it mrans as x increases z decreases.
f(x,y)=10-x^2-y^2
To find derivative of z w.r.t. y is treat any other variable as a constant.
dz/dx=0-0-2y
dz/dx=-2y
Evaluating this at (7,-3) gives us dz/dy=-2(-3)=6.
Since this result is positive it mrans as y increases z decreases.
I dont understand that I can’t see the picture that good
For number 1 the answer is 112
