The amount of the periodic payment necessary for the deposit to a sinking fund is approximately $18,065.19.

To find the amount of the periodic payment necessary for the deposit to a sinking fund, we can use the formula for the future value of an ordinary annuity. The formula is:

X = A * (1 + r)^nt / [(1 + r)^nt - 1]

Where:

X is the amount needed

A is the periodic payment

r is the interest rate per period

n is the number of compounding periods per year

t is the total number of years

Given the information:

Amount Needed (X) = $85,000

Frequency: Quarterly

Rate (r) = 1.4% (or 0.014 as a decimal)

Time (t) = 5 years

Since the frequency is quarterly, the number of compounding periods per year (n) is 4.

Substituting the values into the formula:

$85,000 = A * (1 + 0.014)^(4*5) / [(1 + 0.014)^(4*5) - 1]

Simplifying the equation:

$85,000 = A * (1.014)^20 / [(1.014)^20 - 1]

To find the value of A, we can rearrange the equation:

A = $85,000 * [(1.014)^20 - 1] / (1.014)^20

Using a calculator or spreadsheet, we can calculate the value of A.

A ≈ $85,000 * 0.298 / 1.350

A ≈ $18,065.19

Answer: 88

Step-by-step explanation:

Given

The first row has 16 seats

then there are 3 more seats in each row

this follows an AP with the first term \(a=16\) and common difference \(d=3\)

So, no of seats in the 25 th row is

\(\Rightarrow a_{25}=a+24d\\\Rightarrow a_{25}=16+3\times 24\\\Rightarrow a_{25}=88\)

Thus, there are 88 seats in the 25 th row

When triangle ABC is defined by the coordinates a(2,9), b(8,4), and c, the equation for the line is 5y=6x+8 (-3,-2).

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical phrase with two equal sides and an equal sign is called an equation. The point-slope form, standard form, and slope-intercept form are the three main types of linear equations. Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" symbol and terms on both sides must always be present when writing an equation. Equal treatment should be given to each side.

Here,

A=(2,9)

B=(8,4)

C=(-3,-2)

The slope of line AB,

m=(y2-y1)/(x2-x1)

=(4-9)/(8-2)

=-5/6

Slope of line perpendicular to AB,

m1=-1/m

=-1/(-5/6)

=6/5

This line pass through (-3,-2).

y=mx+c

-2=6/5*(-3)+c

c=-2+18/5

c=8/5

The equation of line,

y=6/5x+8/5

5y=6x+8

The equation of line is 5y=6x+8 when triangle ABC is defined by the points a(2,9), b(8,4), and c(-3,-2).

The geometric power series for the function f(x) = 1 / (9 + x), centered at 0, using long division is (9 - x) / ((9 + x) * (9 - x)).

To find a geometric power series for the function f(x) = 1 / (9 + x) using long division, we can start by expanding the function into a fraction:

f(x) = 1 / (9 + x)

To begin the long division process, we divide 1 by 9 + x:

1 ÷ (9 + x)

To simplify the division, we can multiply the numerator and denominator by the conjugate of the denominator:

1 * (9 - x) / ((9 + x) * (9 - x))

Simplifying further:

(9 - x) / (81 - x^2)

Now, we have expressed the function f(x) as a fraction with a simplified denominator. To find the geometric power series, we can rewrite the denominator using the concept of a geometric series:

(9 - x) / (81 - x^2) = (9 - x) / (9^2 - x^2)

We can see that the denominator is now in the form a^2 - b^2, which can be factored as (a + b)(a - b). In this case, a = 9 and b = x:

(9 - x) / (9^2 - x^2) = (9 - x) / ((9 + x)(9 - x))

Now, we can express the function f(x) as a geometric power series:

f(x) = (9 - x) / ((9 + x)(9 - x))

f(x) = 1 / (9 + x) = (9 - x) / ((9 + x)(9 - x))

f(x) = (9 - x) / (9^2 - x^2) = (9 - x) / ((9 + x)(9 - x))

f(x) = (9 - x) / ((9 + x) * (9 - x))

f(x) = 1 / (9 + x) = (9 - x) / ((9 + x) * (9 - x))

The geometric power series for the function f(x) centered at 0 is given by (9 - x) / ((9 + x) * (9 - x)).

The transmission speed of the circuit cannot be calculated without knowing the number of channels. The formula requires the number of channels in addition to the number of samples per second and the number of bits per sample.

We can use the following formula to calculate the transmission speed of the circuit.

Bandwidth = (Number of samples per second) × (Number of bits per sample)

Transmission speed = Bandwidth × Number of channels.

The given number of bits per sample is 16 and the number of samples taken each second is 8000.

Transmission speed = Bandwidth × Number of channels

Transmission speed = (Number of samples per second) × (Number of bits per sample) × Number of channels

The transmission speed on the circuit is calculated by multiplying the number of samples per second by the number of bits per sample and the number of channels.

However, the number of channels is not provided. So, we cannot calculate the transmission speed of the circuit.

Answer:

x= -4, y= -20

Step-by-step explanation:

y= 16x+44

(y= -x²+8x+28) * (-1)

multiply both sides by -1  

y= 16x+44

-y= x²-8x-28

add the equations to eliminate y

y-y= x²+16x-8x+44-28

0= x² +8x +16 this is the same with (x+4)²=0 so x= -4

go back to the first equation and substitute x with -4 and solve for y

y= 16*(-4) +44 = -64+44 = -20

Answer:  C

Step-by-step explanation:

If a parabola is given by \(a(x - h)^2 + k\), the focus is at the point \((h, k + 1/4a)\).

We know the focus is \((3, 8)\), so it should look like \(a(x - 3)^2 + k\). We can cross off B and D.

Let's check if A works: \(8 = -9 + 1/(4 \cdot \frac 14) = -8\). Obviously this is false, so we can cross off A.

Thus it's C by process of elimination.

Answer:

y = 16

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = \(\frac{k}{x}\)

To find k use the condition y = 14 when x = 8, thus

14 = \(\frac{k}{8}\) ( multiply both sides by 8 )

112 = k

y = \(\frac{112}{x}\) ← equation of variation

When x = 7, then

y = \(\frac{112}{7}\) = 16

Where f(x) is the probability density function of X. In both cases, the expected value represents the average outcome or value that can be expected over many trials or observations.

The formula for the expected value or mean probability is a long answer that depends on the specific situation or probability distribution being analyzed.

In general, the expected value is calculated by multiplying each possible outcome by its corresponding probability and then summing these products together.

For discrete probability distributions, this formula can be written as:
E(X) = Σ(x * P(X=x))

Where X is the random variable, x is a possible outcome, and P(X=x) is the probability of X taking on the value x.

For continuous probability distributions, the formula is similar, but involves integration instead of summation:
E(X) = ∫(x * f(x)) dx

Where f(x) is the probability density function of X. In both cases, the expected value represents the average outcome or value that can be expected over many trials or observations.
