Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Find the partial derivatives indicated Assume the variables are restricted to a domain on which the function is defined. z=
+
+
a) Zx b) Zy
In differentiation, if y = axⁿ, y' = 
. Applying this in question;
Given the function z = x⁸++
Note that y is treated as a constant since we are to differentiate only with respect to x.
For Zy;
Here x is treated as a constant and differential of a constant is zero.
The answer to your question is x = 8
Answer:
The equivalent expression is 
A is correct
Step-by-step explanation:
We are given two complex number and need to multiply it. To find equivalent fraction.
Using Binomial product property: (a+b)(c+d)=ab+ad+bc+bd
Combine the like term and simplify
Hence, The equivalent expression is
Answer:
Step-by-step explanation:
we know that
In the triangle XYZ
Applying the law of sines
solve for z
Answer:
12x - 15 dollars
Step-by-step explanation:
Sunny earns $12 per hour for delivering cakes.
She worked for x hours this week.
Unfortunately, she was charged $15 for a late delivery on Tuesday
She was supposed to earn $12 × x = $12x this week
But she was charged $15 for late delivery on Tuesday
So her net earning this week is; $12x - $15
