The x in the formula is the depth.

You are given two different depths, replace x with the depths, solve for T, then subtract the to find the difference:


At 1200 meters the temperature is:

T = 4500/1200 = 3.75 degrees


At 3750 meters the temperature is:

T = 4500 / 3750 = 1.20 degrees.


The difference in temperature between the two depths is:

3.75 - 1.20 = 2.55 degrees C.

Which values from this set {−12, −9, −3, 0, 3, 6} satisfy this inequality?
Vesna [10]

The values -3, -9 and -12 satisfy the inequality.

In this question we evaluate each element of the set to determine whether value belongs to the inequation given on statement:

x = 0

-13\cdot 0 + 3 \ge 6

3\ge 6 (FALSE)

x= -3

-13\cdot (-3) +3 \ge 6

42\ge 6 (TRUE)

x = -9

-13\cdot (-9)+3 \ge 6

120\ge 3 (TRUE)

x = -12

-13\cdot (-12) +3 \ge 6

159 \ge 6 (TRUE)

The values -3, -9 and -12 satisfy the inequality.

The weekly demand and supply functions for Sportsman 5 × 7 tents are given by
Viktor [21]
The equilibruim point of a demand and supply function is the point at which the quantity demanded is equal to the quantity supplied.

Given the demand function as
p = -0.1x^2 - x + 33
and the supply function as
p = 0.1x^2 + 2x + 13

The equilibruim quantity is obtained as follows:
-0.1x^2 - x + 33=0.1x^2 + 2x + 13 \\  \\ \Rightarrow0.2x^2+3x+46=0 \\  \\ \Rightarrow x=-7.5\pm13.18i

There is no real equilibruim quantity and price for the given demand and supply function.

The functio p(x)= x(x-5)(x-2)(x+3) has four zeros. What is the smallest zero.
loris [4]

Answer:

x = 5 or x = 2 or x = 0 or x = -3 thus 0 is the smallest root

Step-by-step explanation:

Solve for x:

x (x - 5) (x - 2) (x + 3) = 0

Split into four equations:

x - 5 = 0 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 5 to both sides:

x = 5 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 2 to both sides:

x = 5 or x = 2 or x = 0 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = 5 or x = 2 or x = 0 or x = -3
