From each 100 call 24 makes a reservation, if an operator handles 15 calls then the question is the chances of 15/76 giving the answer of 19%

missed my lecture and need help with this derivative, I tried looking at online resources but I just got confused so if someone

Derivative with respect to x: $12x^2y^2-\frac{z^3}{x}+16x^{15}$

Derivative with respect to y: $8x^3y-4e^zy^3+4$

Derivative with respect to z: $-e^z y^4 +\frac{3z^2}{x^2}$

Step-by-step explanation:

We can calculate three derivatives for this function: the derivative with respect to x, the derivative with respect to y, and the derivative with respect to z.

We start with the derivative with respect to x:

$\frac{df}{dx}=4(3x^{3-1})y^2 -0 +z^3(-x^{-1})+0-16x^{16-1}=\\=12x^2y^2-\frac{z^3}{x}+16x^{15}$

Then we calculate the derivative with respect to y:

$\frac{df}{dy}=4x^3(2y^{2-1})-e^z(4y^{4-1})+0+4y^{1-1}=8x^3y-4e^zy^3+4$

Finally, we calculate the derivative with respect to z:

$\frac{df}{dz}=0-e^z y^4 +\frac{3z^{3-1}}{x^2}+0-0=-e^z y^4 +\frac{3z^2}{x^2}$

Jonathan ran five days a week. The most he ran in one day was 3.5 miles. Write an inequality that shows the distance jonathan co

natka813 [3]

Answer: $x\leq17.5$

Step-by-step explanation:

Given: The number of days Jonathan ran = 5

The most he ran in 1 day = 3.5 miles

Therefore, the maximum distance he ran in a week= $5\times3.5=17.5\ miles$

Let x be the distance Jonathan could have rum in a week, such that

$x\leq17.5$

Hence, the required inequality is $x\leq17.5$ .

Determine if the lines are parallel, perpendicular or neither y=-3/2x-4 and y=2/3x-7

aliya0001 [1]

Answer:

<u>They are perpendicular</u>

Step-by-step explanation:

Perpendicular lines have slopes that are negated versions of the other or positive versions of the slope of the other. The slopes are also flipped.

Parallel lines have the same slope.

Neither is when the lines do not follow either of these definitions.

The slope of your two lines are -3/2 and 2/3. These slopes are flipped and the opposite negations of each other. <u>This means the lines are perpendicular.</u>
