Jim changes his passwords every 90 days and cleans out his files every 50 days. If he just did both on the same day, what is the least number of days before he changes them both again on the same day?

Answer:522

522x18=  so 522x8=4176    522x1=522 add those up and get 4176+522=4698

Answer:

The ball will reach a maximum height of 39.993 meters after 1.428 seconds.

Step-by-step explanation:

Let suppose that no non-conservative forces acts on the ball during its motion, then we can determine the maximum height reached by the Principle of Energy Conservation, which states that:

[tex]K_{1}+U_{g,1} = K_{2}+U_{g,2}[/tex] (1)

Where:

[tex]K_{1}[/tex], [tex]K_{2}[/tex] - Initial and final translational kinetic energies, measured in joules.

[tex]U_{g,1}[/tex], [tex]U_{g,2}[/tex] - Initial and final gravitational potential energies, measured in joules.

By definition of translational kinetic energy and gravitational potential energy we expand and simplify the expression above:

[tex]\frac{1}{2}\cdot m\cdot v_{2}^{2}+m\cdot g\cdot y_{2}= \frac{1}{2}\cdot m\cdot v_{1}^{2}+m\cdot g\cdot y_{1}[/tex] (2)

Where:

[tex]m[/tex] - Mass of the ball, measured in kilograms.

[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.

[tex]v_{1}[/tex], [tex]v_{2}[/tex] - Initial and final speed of the ball, measured in meters per second.

[tex]y_{1}[/tex], [tex]y_{2}[/tex] - Initial and final heights of the ball, measured in meters.

The final height of the ball is determined by the following formula:

[tex]v_{2}^{2}+2\cdot g\cdot y_{2} = v_{1}^{2}+2\cdot g\cdot y_{1}[/tex]

[tex]v_{1}^{2}-v_{2}^{2}+2\cdot g \cdot y_{1}=2\cdot g\cdot y_{2}[/tex]

[tex]y_{2} = y_{1}+\frac{v_{1}^{2}-v_{2}^{2}}{2\cdot g}[/tex] (3)

If we know that [tex]y_{1} = 30\,m[/tex], [tex]v_{1} = 14\,\frac{m}{s}[/tex], [tex]v_{2} = 0\,\frac{m}{s}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], the maximum height that the ball will reach is:

[tex]y_{2} = 30\,m + \frac{\left(14\,\frac{m}{s} \right)^{2}-\left(0\,\frac{m}{s} \right)^{2}}{2\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]

[tex]y_{2} = 39.993\,m[/tex]

The ball will reach a maximum height of 39.993 meters.

Given the absence of non-conservative forces, the ball exhibits a free fall. The time needed for the ball to reach its maximum height is computed from the following kinematic formula:

[tex]t = \frac{v_{2}-v_{1}}{-g}[/tex] (4)

If we know that [tex]v_{1} = 14\,\frac{m}{s}[/tex], [tex]v_{2} = 0\,\frac{m}{s}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then:

[tex]t = \frac{0\,\frac{m}{s}-14\,\frac{m}{s} }{-9.807\,\frac{m}{s^{2}} }[/tex]

[tex]t = 1.428\,s[/tex]

The ball will take 1.428 seconds to reach its maximum height.

Step-by-step explanation:

Use KCF method

Keep the first number, Change division to multiplication and flip the second number.

4 ÷ [tex]\frac{4}{3} = 4 * \frac{3}{4} = 1 * 3 = 3[/tex]

Answer: C. 1 1/3

Step-by-step explanation:

Slope is calculated by the change in y/the change in x.

Plug values from the table into the equation:

(19-15)/(4-1)

Evaluate and Simplify:

4/3 -> 1 1/3

The solution is: A) f(x) = -3x + 7 is the same function as -3x + 7 = y.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, we have,

given that,

the function is:  -3x + 7 = y

now, we have to find the same function as -3x + 7 = y.

now, let, the function is represented by f(x)

so, we have,

y = f(x)

so, we get,

f(x) = y = -3x + 7

we get,

f(x) = -3x + 7

so, f(x) = -3x + 7  is the same function as -3x + 7 = y.

Hence, A) f(x) = -3x + 7 is the same function as -3x + 7 = y.

Answer:

The percent of increase in the shoreline was 38%.

Step-by-step explanation:

Given that the shoreline increased from 10 miles to 13.8 miles because of the spring runoff, to determine the percentage by which the shoreline increased, the following calculation must be performed:

10 = 100

13.8 = X

((13.8 x 100) / 10) = X

(1,380 / 10) = X

138 = X

Thus, since 138 - 100 is equal to 38, the percentage by which the shoreline increased was 38%.
