what is the half-life of the radionuclide that shows the following decay curve?

Answers

Answer 1

Decay constant: the ratio of the number of radioactive atoms in a population to the rate at which they are vanishing due to radioactive decay. The rate of change is determined by the equation dN/dt = N, where is the decay constant, assuming N is the size of a population of radioactive atoms at a particular time t and dN is the amount by which the population declines in time dt.

When this equation is integrated, N = N0et is obtained, where N0 is the starting population size of radioactive atoms at time t = 0. This demonstrates that the rate of population decay is dependent on the decay constant and is exponential.

Answer:

z = [tex]\sqrt{117}[/tex]

Step-by-step explanation:

find 'y' first by using the altitude rule:

y/4 = 9/y

cross-multiply:

y² = 4(9)

y² = 36

y = [tex]\sqrt{36}[/tex] = 6

Find 'z' by using the Pythagorean Theorem with legs equal to 6 and 9

6² + 9² = z²

36 + 81 = z²

117 = z²

z = [tex]\sqrt{117}[/tex]

3x – 4y = 31
y = -2x + 6

Answers

Answer:

x = 5

Step-by-step explanation:

3x – 4y = 31

y = -2x + 6

Plug in Y

3x – 4(-2x + 6) = 31

Distribute

3x +8x-24= 31

Add like terms

11x - 24 = 31

Add 24 on both sides

11x = 55

Divide both sides by 11

x = 5

Step-by-step explanation:

Simplify the following:

(sqrt(14))/(sqrt(18))

Hint: | Simplify radicals.

sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):

(sqrt(14))/(3 sqrt(2))

Hint: | Multiply numerator and denominator of (sqrt(14))/(3 sqrt(2)) by sqrt(2).

Rationalize the denominator. (sqrt(14))/(3 sqrt(2)) = (sqrt(14))/(3 sqrt(2))×(sqrt(2))/(sqrt(2)) = (sqrt(14) sqrt(2))/(3×2):

(sqrt(14) sqrt(2))/(3×2)

Hint: | Multiply 3 and 2 together.

3×2 = 6:

(sqrt(14) sqrt(2))/6

Hint: | For a>=0, sqrt(a) sqrt(b) = sqrt(a b). Apply this to sqrt(14) sqrt(2).

sqrt(14) sqrt(2) = sqrt(14×2):

(sqrt(14×2))/6

Hint: | Multiply 14 and 2 together.

14×2 = 28:

(sqrt(28))/6

Hint: | Simplify radicals.

sqrt(28) = sqrt(2^2×7) = 2 sqrt(7):

(2 sqrt(7))/6

Hint: | In (2 sqrt(7))/6, divide 6 in the denominator by 2 in the numerator.

-The expressions are only equivalent for x = 4 and x = 6.
-The expressions are only equivalent when evaluated with even values.
-The expressions have equivalent values for any value of x.
-The expressions should have been evaluated with one odd value and one even value.
-When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
-The expressions have equivalent values if x = 8.

Graph the line passing through (6,−2) whose slope is m=−3

Answers

Answer:

Step-by-step explanation:

When you know the slope m of a line and a point (x₀,y₀) on the line, you can write an equation for the line in "point-slope" form:

y-y₀ = m(x-x₀)

In your case,

y+2 = -3(x-6)

The line is easier to graph if you rearrange the equation to solve for y:

y = -3x+16

You know that (0,16) is one of the points on the line.

Plot the two points that you know, (6,-2) and (0,16), then draw a line through them.

Miguel withdrew $20 per week from his bank account for 4 weeks. Which expression shows the change in his account balance?
A. -20+4
B. -20-4
C. -20x4
D. -20 ÷4

Answers

Answer:

c

Step-by-step explanation:

The expression that shows the change in Miguel's account balance is -20×4. Thus, option (C) is correct.

Given, Miguel withdrew $20 per week from his bank account for 4 weeks.

Since he withdrew money, the change in his account balance would be negative.

The expression -20 represents the amount he withdrew each week, and the -4 represents the number of weeks.

Multiplying 4 with the initial balance of -20 gives us the change in his account balance.

Therefore, the expression -20×4 correctly represents the change in Miguel's account balance.
