A sample of 400 grams of radioactive substance decays according to the function A(t) = 400e^-.046t, where t is the time in years

algol13

Answer: There will be 0.04 grams will be left in the sample after 20 years.

Step-by-step explanation:

Since we have given that

$A(t)=400e^{-0.46t}$

Here, Initial amount of radioactive substance = 400 grams

We need to find the amount of substance that will be left in the sample after 20 years.

So, t = 20 years

So, it becomes,

$A(t)=400e^{-0.46\times 20}\\\\A(t)=400e^{-9.2}\\\\A(t)=0.04\ grams$

Hence, there will be 0.04 grams will be left in the sample after 20 years.

Determine whether each of the following functions is even, odd, or neither even nor odd.

Illusion [34]

Answer:

A.) Even.

Step-by-step explanation:

If a function is an even function, then

F(-x) = f(x)

Also, if a function is an odd function, then, f(-x) = -f(x)

You are given the below function

f(x) = 1 + 3x^2 − x^4

Let x = 2

Substitute 2 for x in the function

F(x) = 1 + 3(2)^2 - (2)^4

F(x) = 1 + 3(4) - 16

F(x) = 1 + 12 - 16

F(x) = -3

Also, Substitute -2 for x in the function

F(x) = 1 + 3(-2)^2 - (-2)^4

F(x) = 1 + 3(4) - 16

F(x) = 1 + 12 - 16

F(x) = -3

Since f(-x) = f(x), we can conclude that

F(x) = 1 + 3x^2 - x^4 is even

Renaldo will write 3/20 as a decimal. Which of the following methods should he use?

makvit [3.9K]

ANSWER

1. Multiply the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

EXPLANATION

Renaldo wants to write

$\frac{3}{20}$

as a decimal.

He needs a denominator of 100, so he can multiply by

$\frac{5}{5}$

to obtain:

$\frac{3}{20} = \frac{3 \times 5}{20 \times 5}$

This will be

$= \frac{15}{100}$

He can now obtain the decimal equivalent as

$= 0.15$

The correct choice is option 1.
