Answer:

17x+6y+4x-9

Step-by-step explanation:

The numbers and varibles in the equation 4x-9+6y+17x are the same as 17x+6y+4x-9 meaning they would look the same simplified.

Find all the second partial derivatives. v = e5xey
Helga [31]
I'm taking the liberty of editing your  function  <span>v = e5xey:  It should be 
</span>
<span>v = e^5x^ey, with " ^ " indicating exponentiation.
</span>
Did you mean e^(5x) or (e^5)x?  I'll assume it's e^(5x).

The partial of   v = e^(5x)e^y with respect to x is e^(5x)(5)*e^y, or 25x*e^y.

The partial of v = e^(5x)e^y with respect to y is e^(5x)e^y.

Keri is simplifying 5·10^−3.
11111nata11111 [884]

Answer:

1. D

2. A

Step-by-step explanation:

Q1. Kerry is simplifying 5\cdot 10^{-3}

By the definition of negative powers,

a^{-n}=\dfrac{1}{a^n}

Hence,

10^{-3}=\dfrac{1}{10^3}

So, the first step in simplifying the expression is

5\cdot 10^{-3}=5\cdot \dfrac{1}{10^3}

Q2. Given the expression

\dfrac{8}{10^{-2}}

First, use the definition of negative powers:

10^{-2}=\dfrac{1}{10^2}

Thus,

\dfrac{8}{10^-2}=\dfrac{8}{\frac{1}{10^2}}=8\cdot 10^2=8\cdot 100=800

15 less than quadruple a number w​
vichka [17]

Answer:

4w-15

Step-by-step explanation:

For expressions that have "more than/less than" , that number goes AFTER the "whatever a number" statement because that's just how they explain it. I don't remember the exact reason why, but that is how my professor made me remember it, and yes, the order WILL affect the expression since that's a specific topic and I suppose you're being tested on how to make algebraic expressions based on descriptions.

mixas84 [53]

Answer:

According to Angle Bisector Theorem, if Ray YZ is an angle bisector, then MZ and NZ are congruent.

EH= 23. It is shown that ray FH bisects EFG, EF and EH are perpendicular, FG and HG are perpendicular. Then EH and GH are congruent. Therefore since GH= 23, then EH= 23
