Answer:

  k ≈ -0.06729

Step-by-step explanation:

The initial temperature difference is 85 -36 = 49 degrees. After 5 minutes, the temperature difference is 71 -36 = 35 degrees. The constant k is the natural log of the ratio of these temperature differences, divided by the time unit.

  k = ln(35/49)/5 ≈ -0.06729

__

The equation for the temperature T of the can in the refrigerator is ...

  T = 49e^(-0.06729t) +36

_____

<em>Additional comment</em>

Be careful with the sign. If you're filling in k in e^(-kt), then the sign of k will be positive. Above, we have taken the form of the exponential term to be e^(kt), so k is negative.

A vertical shift of 3 units down and a horizontal shift of 2 units to the right
Lubov Fominskaja [6]
Depends on what the coordinates are to get an exact answer but you go down on your y axis 3 units (so if it was at 0 it would become -3) and to the right on your x axis, which means the numbers are increasing ( so if it was 3 it would become 5.)

Determine what type of model best fits the given situation: Farmer Joe has 1,000 bushels of corn to sell. Presently the market p
mart [117]

Answer:

The correct option is;

C. Quadratic

Step-by-step explanation:

The given information are;

The quantity of corn Farmer Joe has to sell = 1,000 bushels

The present market price for corn = $5.00 a bushel

The amount by which he expects the market price to rise per week =$0.15

The number of bushels lost to spoilage per week = 10

Therefore, we have;

The value of the corn = Amount of corn left × Price of corn

The price of the corn per bushel with time = 5 + 0.15×t

The amount of corn left = 1000 - 10×t

Where;

t = Time in minutes

Therefore, the total value of corn = (1000 - 10×t)×(5 + 0.15×t) = -1.5·t²+100·t+5000 which is a quadratic model.

Therefore, the correct option is a quadratic model.

Can you solve this :-)? Identify the equation that means "eleven less than x is twenty-three" (A) x = 23 - 11. (B) x + 11 = 23.
mart [117]
Hey user!!

your answer is here (-:

given :- eleven less than x ( x - 11 ) = twenty three

final answer = x - 11 = 23

correct option is D. x - 11 = 23

if u need the value of x too, then Answer is :-

x - 11 = 23

x = 23 + 11

x = 34

cheers!!
