Answer:

D(Yes;-5) is correct.

Step-by-step explanation:

Let's check 2 consecutive numbers

A(1) = 18

A(2) =13

=> common difference=A(2)-A(1) = 13-18 =-5

(Also, we see A(4)-A(3) = A(3)-A(2) =-5)

Kayla ran from her home to a beach at a speed of 6 meters per second. the distance from her home and the beach was 756 meters. A
german
Looking at the units, 756 meters divided by 6 m/s will give you the seconds that you need.

So for A) 756/6 = 126

For B, you take the answer from A, and subtract 18 seconds, which would make it 108.  Then you take the distance, 756 and divide by 108, that will be the speed.

Find the partial derivatives indicated Assume the variables are restricted to a domain on which the function is defined. z=x8+3y
ahrayia [7]

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=x^{8}+3^{y}+x^{y}

a) Zx b) Zy

In differentiation, if y = axⁿ, y' = nax^{n-1} \ where \ n\ is\ a\  constant. Applying this in question;

Given the function z = x⁸+3^{y}+x^{y}

Z_x = \frac{\delta z}{\delta x} = 8x^{7} + 0 + yx^{y-1} \\\frac{\delta z}{\delta x} = 8x^{7} + yx^{y-1} \\

Note that y is treated as a constant since we are to differentiate only with respect to x.

For Zy;

Z_y = \frac{\delta z}{\delta y} =0+ 3^{y} ln3 + x^{y}lnx \\\frac{\delta z}{\delta y} = 3^{y} ln3 + x^{y}lnx } \\

Here x is treated as a constant and differential of a constant is zero.

The sum of two numbers is 15. The difference of he same two numbers is 3. What are the two numbers?
Angelina_Jolie [31]

x+y =15

x-y = 3

add the two equations

2x = 18

divide by 2

x = 9

x + y = 15

9 + y =15

subtract 9

y = 9

The two numbers are 6 and 9
