0.25Q+0.05N=3.25 and Q+N=31 is the required system of equation and nickels should be 22.5 and Quarters should be 8.5

Two or more expressions with an Equal sign is called as Equation.

From given,

3.35$ in quarters and nickels. If you have 31 coins

0.25Q+0.05N=3.25..(1)

Q+N=31

Q=31-N

Now substitute Q value in (1)

0.25(31-N)+0.05N=3.25

7.75-0.25N+0.05N=3.25

7.75-0.2N=3.25

Subtract 7.75 on both sides

-0.2N=3.25-7.75

-0.2N=-4.5

Divide both sides by 0.2

N=22.5

and Q+22.5=31

Q=31-22.5

Q=8.5

The measure of the unknown angles in the circle are

x° = 38°

y° = 90°

z° = 90°

From the question, we are to determine the measure of the unknown angles.

From one of circle theorems, we have that "the angle in a semicircle is a right-angle"

Thus,

y° = 90°

z° = 90°

To determine the measure of x°

Using the theorem,

"The angle subtended by an arc at the center of a circle is twice the angle subtended at the circumference"

Thus,

x° = 2 × 19°

x° = 38°

Hence, x° = 38°, y° = 90°, and z° = 90°

201 numbers are less than 2017

If and only if it is odd, a number is the sum of two successive integers.

Only if it is a multiple of 5 is a number considered to be the sum of 5 consecutive integers. If you have any doubts, remember that the product of five consecutive integers equals five times the integer in the middle (this remains true if instead of 5 you put in any odd positive integer).

Consequently, you are seeking odd multiples of 5 below 2017. There are 403 multiples of 5 immediately below 2017, or 2015/5. Of those, 202 are odd.

The linear function that passes through (-8,4) and (4,5) will be y = (1/12)x + 14/3.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

A linear equation or function is given as ;

y = mx + b

The slope (m) associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

The slope associated with (-8,4) and (4,5) will be as,

m = (5 - 4)/(4 + 8) = 1/12

Thus, y = (1/12)x + b

Put (4,5)

5 = (1/12)4 + b

b = 5 - 1/3

b = 14/3

Thus, y = (1/12)x + 14/3

Hence "The linear function that passes through (-8,4) and (4,5) will be y = (1/12)x + 14/3".

Maria wrote incorrectly the function, it is:

y = |x - 4|

And:

She started with the parent absolute value function:

y = |x|

And wrote a translation to the right as:

y = |x + 4|

That is her mistake, a translation to the right of N units is written as:

g(x)= f(x - N)

So for a translation to the right of 4 units, we need to subtract 4 to the input, the actual function that we can see on the graph is written as:

y = |x - 4|

Now, the y-intercept is what we get when we evaluate in x = 0:

y = |0 - 4| = 4

So the y-intercept is (0, 4).

The x-intercept is the value of x such that y = 0, so we need to solve:

|x - 4| = 0

x - 4 = 0

x = 4

The x-intercept is (4, 0).

23.5 days must elapse for a sample of 239np to decay to 0.100% of its original quantity.

Given is the equation for radioactive decay.

N equals N0exp(-λt). We have to determine the λ decay constant.

λ= -(lnN/N0)/t where t = Neptunium-239's half-life, 2.35 days,

and N/N0 = 1/2 where N = Amount of Neptunium-239 after half-life,

and N0 = Amount of Neptunium-239 at the beginning.

Consequently,

λ = (-ln(1/2))/2.35 = 0.294/day.

Neptunium-239 will now degrade to 0.100% of its original value.

N/N₀ × 100 % = 0.100%

N/N₀ = 0.100/100

N/N₀ = 0.001

We calculate the time it takes for Neptunium-239 to decay to this value using the equation for radioactive decay. Making t the formula's subject,

-(lnN/N0)/ = -(ln(0.001))/0.294/day.=  23.5 days

In contrast to the fact that almost all time series contain a random component, certain time series do not.

A TIME SERIES IS WHAT?

A time series is a group of observations of clearly defined data points produced over time via repeated measurements. A time series would include, for instance, calculating the amount of retail sales for each month of the year. This is due to the well defined and regular measurement of sales income at uniformly spaced intervals. Time series data are not those that are irregularly or once collected.

Three parts can be separated out of a time series observation: the trend (long-term direction), the seasonal (systematic, calendar-related motions), and the irregular (unsystematic, short term fluctuations).

In mathematics, a time series is a collection of data points that have been indexed chronologically.

A time series is typically a sequence that was recorded at a number of evenly spaced points in time.

It is therefore a set of discrete-time data.

Given:  [tex]\textsf{25 frames per second, starts at 0 seconds already played 190 frames}[/tex]

Find: [tex]\textsf{Frame count already played when time = -3.4}[/tex]

Solution: In order to find the number of frames that have already played when the time was equal to -3.4 seconds, we must first figure out long the delay is.  We can do this by dividing 25 frames per second from 190 frames which gives us that 7.6 seconds passed before we started counting at 0.

Therefore, if we want to look at -3.4 seconds out of -7.6 seconds that means that 4.2 seconds passes after the initial playing to get to -3.4 seconds.  Now we can just multiply 4.2 seconds by 25 frames per second which gives us that about 105 frames have played when the time was equal to -3.4
