Answer:  -4

Step-by-step explanation:

Combine r and −5r to get −4r.

dr/d (−4r)

The derivative of nax

 is nax n−1 .

−4r 1−1

Subtract 1 from 1.

−4r0

For any term t except 0, t0

=1.

A certain compound has a half-life of four days. Write and use an exponential decay function to find the amount of compound rema
dimaraw [331]

Answer:

1.97 ounces

Step-by-step explanation:

-The exponential decay function is given by the formula:

P_t=P_oe^{-rt}\\\\

Given that the half-life is 4 days, we can substitute in the formula to solve the rate of decay for a single half-life:

P_t=P_oe^{rt}\\\\P_t=0.5P_o\\\\\therefore 0.5=e^{-4r}\\\\-4r=In(0.5)\\\\r=0.17329

#Since, 1 week has 7 days, 3 weeks is a 21-day period, thus, t=21.

#We substitute and solve for the amount remaining after 21days of decay:

P_t=P_oe^{-rt}\\\\=75e^{-21\times 0.17329}\\\\=1.97072\\\\\approx1.97 \ oz

Hence, the amount remaining after 3 weeks of decays is approximately 1.97 ounces

zysi [14]

Answer:

<em>See the Venn diagram attached</em>

<u>Numbers given:</u>

  • <em>Total</em>: 100
  • Either a cat of a fish: 70
  • Cat: 46
  • Cat and fish: 16

<u>Neither a cat or a fish:</u> 100 - 70 = 30

<u>Fish:</u> 70 - (46 + 16) = 70 - 62 = 8

<u>Required probabilities are:</u>

  • a) P(neither) = 30/100 = 0.3
  • b) P(f) = (16 + 8)/100 = 0.24
  • c) P(f not c) = 8/100 = 0.08

In ΔDEF, the measure of ∠F=90°, DF = 24, FE = 7, and ED = 25. What ratio represents the sine of ∠E?
kumpel [21]

Answer:

24/25

Step-by-step explanation:

In this triangle DF and FE are legs (because they form the right angle) , ED is the hypotenuse (it is the largest side, it is opposite to the right angle).

son of E is the ratio of the leg opposite to the angle E (DF) to the hypotenuse

it is 24/25
