The daytime temperature in Apple Valley is falling by 2.5 degrees each day. What will the net change in the daily temperature be

nexus9112 [7]

Answer:

Option D -17.5 degrees is correct answer

Step-by-step explanation:

Since a calendar week has 7 days. and temperature is falling by -2.5 daily.

So, On Day 1 Temperature is -2.5 degrees

On Day 2 Temperature is -2.5 + -2.5 = -5 degrees

On Day 3 Temperature is = -5 + -2.5 = -7.5 degrees

On Day 4 Temperature is = -7.5 + -2.5 = -10 degrees

On Day 5 Temperature is = -10 + -2.5 = -12.5 degrees

On Day 6 Temperature is = -12.5 + -2.5 = -15 degrees

On Day 7 Temperature is = -15 + -2.5 = -17.5 degrees

So, Option D -17.5 degrees is correct answer.

jarptica [38.1K]

First, you set up the equation which would be 5y-8=3y-4.
-3y -3y
2y-8= -4
+8 +8
2y=4
divide by 2
y=2

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.
