The chart shows rate of decay. A 3 column table with 7 rows. The first column is Half-lives elapsed, with entries 0, 1, 2, 3, 4,
Morgarella [4.7K]

The value that is being measured in the columns labeled "Fraction remaining" and "Percentage remaining" is (d) amount of material that has not decayed.

From the question, we understand that the chart measures the rate of decay.

<h3 /><h3>Fraction Remaining</h3>

So, the fraction remaining column would show the remaining amount of the material that is being measured, as a fraction.

<h3>Percentage Remaining</h3>

The percentage remaining column would show the remaining amount of the material that is being measured, as a percentage.

Hence, the value that is being measured in these columns is (d) amount of material that has not decayed.

use a numerical method to estimate the value of the limit (if it exists.) Lim e^5t -1 /t as x tends to 0 from both sides​
charle [14.2K]

Hello from MrBillDoesMath!

Answer:

5

Discussion:

Consider the expansion of e^x:

e^x = 1 + x + x^2/2 + x^3/6 +......            =>      replace x by 5t

e^(5t) = 1 + (5t)  + (5t)^2/2 + ....              =>      subtract 1 from both sides

e^(5t) - 1 = (5t) + (5t)^2/2+....                  =>      divide both sides by t

(e^(5t) -1)/ t = 5 + (25/2)  t +....

so as t ends to 0  the quotient tends to    

5 + (25/2)0 + (other terms) *0   ->   5

Thank you,

MrB

lutik1710 [3]

Answer:

6 toppings

Step-by-step explanation:

The t in this equation represents the amount of toppings.

22 + 0.65t = 26

-22 -22

0.65t = 4

0.65t/0.65 = 4/0.65

t = 6

They could get 6 toppings and the total would be $25.90.

2x + y =8 and 4x -2y = 6
irakobra [83]

Answer:

x=1.25 and y=-5.5

Step-by-step explanation:

2x+y=-8, 2x=-y-8 or 4x=-2y-16. Plug this value in the second equation, we have - 2y-16-2y=6, y=-5.5. Plugging this in any equation we have, x=1.25
