Answer:

B

Step-by-step explanation:

Looking at the problem, we see that our constant rate is 999/1000 because the pressure is only nine hundred ninety-nine <em>hundredths</em> of the previous pressure. Since this is a rate, it can't be a linear function, so eliminate C.

Now, look at the rate. 999/1000 < 1, which means that the function is decreasing as the x values approach infinity or grow larger. That is an indication that this is an exponential <em>decay</em>.

The answer is thus B.

COOKING Franklin is cooking a 3-pound turkey breast for 6 people. If the number of pounds of turkey varies directly with the num
Gwar [14]

<u>Answer-</u>

2, 4, and 8 people will need 1, 2, 4 pounds of turkey respectively.

<u>Solution-</u>

Given in the question, number of pounds of turkey varies directly with the number of people, i.e as the number of people increases or decreases, the pound of turkey also increases or decreases.  

Taking,

x = number of people,

y = pounds of turkey.

This condition can be represented as,

\Rightarrow y\ \alpha \ x\\\Rightarrow y=kx

As given in the question, when x = 6 y = 3

\Rightarrow 3=k\times 6

\Rightarrow k=\frac{3}{6}= \frac{1}{2}

Now, putting the values of k in the equation, the equation becomes

\Rightarrow y=\frac{1}{2}x

Now, we can get the values of y or number of pounds of turkey needed by putting the given x or number of people.

All the calculations are shown in the attached table.

9d - 5 = 4d + 35<br> find what d equals.
Debora [2.8K]
9d - 5 = 4d + 35

9d (-4d) - 5 (+5) = 4d (-4d) + 35 (+5)

5d = 40

5d/5 = 40/5

d = 8
