The decay constant for the plutonium is - [ln (0.5 ) / 6300].

option C.

The decay constant for the plutonium is calculated by applying the following formula.

The given function for the radioactive decay;

\(Q(t) = Q_0e^{-kt}\)

where;

The decay constant for the plutonium is calculated as;

k = ln(2) / T½

k = ln(2) / 6300

k = ln(0.5⁻¹) / 6300

k = - [ln (0.5 ) / 6300]

Thus, the decay constant for the plutonium is - [ln (0.5 ) / 6300].

Step-by-step explanation:

5^3 = 5 ✕ 5 ✕ 5, and 5 ✕ 5 ✕ 5 = 125

Answer:

125

Step-by-step explanation:

all you have to do is 5*5*5. so multiply the number that many times it tells you on the exponent.

The arrow is at a height of 48 ft after approx. 3 - √6 s and after 3 + √6 s.

To find the time it takes for the arrow to reach a height of 48 ft, we can use the formula for the height of the arrow:

s = v0t - 16t^2

Here, s represents the height of the arrow, v0 is the initial velocity, and t is the time.

Given that the initial velocity, v0, is 96 ft/s and the height, s, is 48 ft, we can set up the equation:

48 = 96t - 16t^2

Now, let's solve this equation to find the time it takes for the arrow to reach a height of 48 ft.

Rearranging the equation:

16t^2 - 96t + 48 = 0

Dividing the equation by 16 to simplify:

t^2 - 6*t + 3 = 0

We now have a quadratic equation in the form of at^2 + bt + c = 0, where a = 1, b = -6, and c = 3.

Using the quadratic formula:

t = (-b ± √(b^2 - 4ac)) / (2a)

Plugging in the values:

t = (6 ± √((-6)^2 - 413)) / (2*1)

t = (6 ± √(36 - 12)) / 2

t = (6 ± √24) / 2

Simplifying the square root:

t = (6 ± 2√6) / 2

t = 3 ± √6

Therefore, the arrow reaches a height of 48 ft after approximately 3 + √6 seconds and 3 - √6 seconds.

In summary, the arrow takes approximately 3 + √6 seconds and 3 - √6 seconds to reach a height of 48 ft, assuming an initial velocity of 96 ft/s.

Answer:

False

Step-by-step explanation:

You first need to distribute the -4 to (x+4).

For the inequality  -5 < 4x + 3 ≤ 7 the  combined solution are x < -2 and x ≤ 1.

To solve the inequality -5 < 4x + 3 ≤ 7, we need to consider two separate inequalities:

Solve the inequality -5 < 4x + 3:

-5 < 4x + 3

Subtract 3 from both sides:

-5 - 3 < 4x

-8 < 4x

Divide both sides by 4

-8/4 > x

-2 > x

x < -2.

Now let's solve the inequality 4x + 3 ≤ 7:

4x + 3 ≤ 7

Subtract 3 from both sides:

4x ≤ 7 - 3

4x ≤ 4

Divide both sides by 4:

x ≤ 1

Therefore, the combined solution is x < -2 and x ≤ 1.

Answer:

Figure J does not show y as a function of x ⇒ D

Step-by-step explanation:

y is a function of x if and only if every x has only one value of y

Let us check each given figure if it shows a function or not

#Figure F

∵ Every value of x has an arrow is pointed to one value of y

∴ Every x has only one value of y

∴ The figure shows y as a function of x

#Figure G

∵ The ordered pairs have different values of x-coordinates

∴ Every x-coordinate has only one value of y-coordinate

∴ The figure shows y as a function of x

#Figure H

∵ Every x in the table appears once

∴ Every x has only one value of y

∴ The figure shows y as a function of x

#Figure J

∵ The ordered pairs were drawn in the figure are (-3, -2), (-3, -3), (-2, 0),

  (-2, -1), (-1, 1), (-1, 2), (0, 3), (0, 4)

∵ x = -3 has two values of y, y = -2 and -3

∵ x = -2 has two values of y, y = 0 and -1

∵ x = -1 has two values of y, y = 1 and 2

∵ x = 0 has two values of y, y = 3 and 4

∴ Every x-coordinate has more than one value of y-coordinate

∴ Figure J does not show y as a function of x

(2x+1)/3 + (5x-2)/2

= (4x+2)/6 + (15x-6)/6

= (4x+2+15x-6)/6

= (19x-4)/6

Answer:

see explanation

Step-by-step explanation:

\(\frac{2x+1}{3}\) + \(\frac{5x-2}{2}\)

we require the denominators of both fractions to be the same value

the LCM of 2 and 3 is 6, so convert both denominators to 6

multiply the numerator/ denominator of the first fraction by 2

multiply the numerator/denominator of second fraction by 3

= \(\frac{2(2x+1)}{3(2)}\) + \(\frac{3(5x-2)}{2(3)}\)

= \(\frac{4x+2}{6}\) + \(\frac{15x-6}{6}\)

now add the numerators, with a common denominator of 6

= \(\frac{4x+2+15x-6}{6}\)

= \(\frac{19x-4}{6}\)

The appropriate domain is the set of values of the independent variable (t) for which the function reasonably makes sense. We are told the model is of prices over a week, and that t represents the number of days since the beginning of the week.

It seems reasonable that the model is intended to apply to a period between t=0 (the beginning of the week) and t=7 (the end of the week). Thus the appropriate domain is ...

Answer:

The hundredth thousands place.I hope this helps. Can you give me brainlest

Step-by-step explanation:

The linear relationship illustrated in the provided table can be effectively described by the equation Y = -4x + 2. Option D.

To determine the equation that represents the given table with the values of x and y, we can observe the pattern and find the equation of the line that fits these points.

Given the table:

X: 2 0 4

Y: -4 3 1

We can plot these points on a graph and see that they form a straight line.

Plotting the points (2, -4), (0, 3), and (4, 1), we can see that they lie on a line that has a negative slope.

Based on the given options, we can now evaluate each equation to see which one represents the line:

Y = 1/2x + 5

When we substitute the x-values from the table into this equation, we get the following corresponding y-values: -3, 5, and 6. These values do not match the given table, so this equation does not represent the table.

Y = -1/2x + 3

When we substitute the x-values from the table into this equation, we get the corresponding y-values: 4, 3, and 2. These values also do not match the given table, so this equation does not represent the table.

Y = 2x - 3

When we substitute the x-values from the table into this equation, we get the corresponding y-values: -4, -3, and 5. These values do not match the given table, so this equation does not represent the table.

Y = -4x + 2

When we substitute the x-values from the table into this equation, we get the corresponding y-values: -6, 2, and -14. Interestingly, these values match the y-values in the given table. Therefore, the equation Y = -4x + 2 represents the table.

In conclusion, the equation Y = -4x + 2 represents the linear relationship described by the given table. So Option D is correct.

Answer:

  (-∞, -3] or [-3, ∞)

Step-by-step explanation:

You want the largest domain interval(s) on which the function shown in the graph could be one-to-one.

A one-to-one function must pass the horizontal line test. That is, no horizontal line can intersect its graph in more than one place.

For that to be true of the given function, the interval on which it is defined cannot include values on both sides of x=-3, where the graph has a minimum. That is, the domain must be either x ≤ -3, or x ≥ -3, (or some subset of either of these).

The largest intervals on which the function has an inverse are ...

  (-∞, -3]  or  [-3, ∞)

<95141404393>

To make the given function one-to-one and have an inverse, we can restrict its domain to (-∞, a) or (a, ∞), where 'a' is the x-coordinate of the highest or lowest point on the graph.

To make the given function one-to-one and have an inverse, we need to restrict its domain. The largest domains, in interval notation, that can be used are: (-∞, a) or (a, ∞) where 'a' is the x-coordinate of the highest or the lowest point on the graph, depending on the function type.

If the graph has a highest point, the domain is restricted to (a, ∞), where 'a' is the x-coordinate of the highest point. If the graph has a lowest point, the domain is restricted to (-∞, a), where 'a' is the x-coordinate of the lowest point.

For example, if the graph has a highest point at (3, 5), the domain would be restricted to (3, ∞) to make the function one-to-one and have an inverse.
