[tex]\textsf{1.} \quad a_n=174-6n[/tex]

[tex]\textsf{2.\;a)} \quad A=5000\left(1.019\right)^{4t}[/tex]

   b)  9.25 years (to the nearest quarter)

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

Given terms of an arithmetic sequence:

Substitute the given values into the arithmetic sequence formula to create two equations:

[tex]\implies a_{28}=a+27d=6[/tex]

[tex]\implies a_{22}=a+21d=42[/tex]

Subtract the second equation from the first equation to eliminate a and solve for d:

[tex]\implies 6d=-36[/tex]

[tex]\implies d=-6[/tex]

Substitute the found value of d into one of the equations and solve for a:

[tex]\implies a+27(-6)=6[/tex]

[tex]\implies a-162=6[/tex]

[tex]\implies a=168[/tex]

Substitute the found values of a and d into the formula to create an equation for the nth term of the sequence:

[tex]\implies a_n=168+(n-1)(-6)[/tex]

[tex]\implies a_n=168-6n+6[/tex]

[tex]\implies a_n=174-6n[/tex]

[tex]\boxed{\begin{minipage}{8.5 cm}\underline{Compound Interest Formula}\\\\$ A=P\left(1+\frac{r}{n}\right)^{nt}$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $n =$ number of times interest is applied per year \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}[/tex]

Given values:

Substitute the given values into the compound interest formula to create an equation with respect to time, t:

[tex]\implies A=5000\left(1+\dfrac{0.076}{4}\right)^{4t}[/tex]

[tex]\implies A=5000\left(1.019\right)^{4t}[/tex]

To find when the value of the investment will be worth more than $10,000, substitute A = 10000 into the equation:

[tex]\implies 10000 < 5000\left(1.019\right)^{4t}[/tex]

[tex]\implies 2 < \left(1.019\right)^{4t}[/tex]

[tex]\implies \ln 2 < \ln\left(1.019\right)^{4t}[/tex]

[tex]\implies \ln 2 < 4t\ln\left(1.019\right)[/tex]

[tex]\implies \dfrac{\ln 2}{4 \ln\left(1.019\right)} < t[/tex]

[tex]\implies t > 9.20672924...[/tex]

Therefore, the investment will be worth more than $10,000 from 9.25 years (to the nearest quarter).

Domain of  y=|x-4|-2 : (-∞, ∞) by -∞ < x < ∞

Range of y=|x-4|-2: [-2, ∞) by F(x) ≥ -2

When a function is applied to its entire set of outputs, the set of outputs it produces is known as its range. The set of things that really leave the function machine after you give it all the inputs is referred to as the range in the metaphor. The set of possible output values for a function is its range.

The range of values that can be plugged into a function is known as its domain. The x values for a function like f are contained in this collection (x). The collection of numbers that the function assumes is known as its range. Following the insertion of an x value, the function outputs this sequence of values.

You graph them.

Go to desmos and put the equations in the calculator. It will graph them for you. Or you could graph them on paper, like the y-intercept is the amount you start with, like 11 or 2 in question 3. then you go two up and one to the side or 1 up and one to the side, depending on how many x there is. or how much the slope is. Like y=x+2 is where you start with (0,2) plot it and then you go one up, one to the side, and then repeat twice. Then plot the line. and in y=11-2x you plot (0,11) and then go down two, one to the side, and repeat twice. Then plot the line.

In question 4, y=3-2x, plot point (0,3) and then go two down, one to the side, and repeat twice. Plot the line. in y=1+2x, plot point (0,1) and then go two up, one to the side.

that's how you plot the slope equation.

Step-by-step explanation:

If A=(4,-5) and 8 (7,-9), 7 units is the length of AB

distance = √( (7−4)^2 + (−9−(−5))^2 )

Plugging in the numbers and solving, we get:

distance = √( (3)^2 + (−4)^2 )

Dividing 3x³ - 4x² - 9x + 15 by 3x + 5. will yield a quotient of x² - 3x + 2 and a remainder of 5 that is (x² - 3x + 2) + 5/(3x + 5).

Applying the long division method will require us to; divide, multiply, subtract, bring down the next number and repeat the process to end at zero or arrive at a remainder.

We shall divide the 3x³ - 4x² - 9x + 15 by 3x + 5 as follows;

3x³ divided by 3x equals x²

3x + 5 multiplied by x² equals 3x³ + 5x²

subtract 3x³ + 5x² from 3x³ - 4x² - 9x + 15 will result to -9x² - 9x + 15

-9x³ divided by 3x equals -3x

3x + 5 multiplied by -3x equals -9x² - 15x

subtract -9x² - 15x from -9x² - 9x + 15 will result to 6x + 15

6x divided by 3x equals 2

3x + 5 multiplied by 2 equals 6x + 10

subtract 6x + 10 from 6x + 15 will result to a remainder of 5

Therefore by the long division method, 3x³ - 4x² - 9x + 15 by 3x + 5 gives a quotient x² - 3x + 2 and a remainder of 5 and can be written as (x² - 3x + 2) + 5/(3x + 5).

Exponentiation, often known as "b raised to the nth power," is a mathematical operation denoted by the symbol bn that involves two numbers: a base number, b, and an exponent, or power, n. Exponents show how many times a number has been multiplied by itself. As an illustration, 2-3 (written as 23) denotes: 2 x 2 x 2 = 8. 23 is not equivalent to 2 + 3 = 6. Recall that an integer raised to the power of one equals itself. A approach to express huge numbers as powers is through the use of exponents. Exponent, then, is the quantity that indicates how many times a number has been multiplied by itself. As an illustration, 6 is multiplied by 4 to provide 6 x 6 x 6 x 6. It may be expressed as 64.

Answer: y = mx + b

y=-3  x=0 and m=2/5

-3 = (2/5)0 + b

Since 2/5(0) is 0, b must be -3

Step-by-step explanation: Since you know the slope and you know one point, all you have to do is plug the slope and the coordinates into the slope-intercept form and solve for b. You can check your answer by finding another point on the line and verifying that the equation works for that point, as well. Add the slope to the given point and you get ( 5 , -1 )

The sum of three consecutive numbers for 150 is 49,50,51.

Three consecutive numbers:  x+(x+1)+(x+2)

x+x+1+x+2= 150

3x+3 = 150

3x = 150-3

3x= 147

X = 147/3

49 =x

But we also need to find (x+1) and (x+2)

49+1= 50

49+2= 51

The three consecutive numbers are 49,50,51.

Darren makes $210.83 monthly payments over a period of 5 years. Therefore, option D is the correct answer.

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

Simple interest is calculated with the following formula: S.I. = (P × R × T)/100, where P = Principal, R = Rate of Interest in % per annum, and T = Time.

Given that, principal =$11,000, rate of interest =3% and time period = 5 years.

Now, S.I. =(11,000×3×5)/100

= $1650

Now, 11,000+1650 =$12650

Answer:

Step-by-step explanation:

The correct answer is true, When using the simple interest formula the time t, is expressed in the same period as the rate.

We can say that the answer is true due to the following reasons,

As we already know, the formula for simple interest is:

Simple Interest = Principal Amount * Rate of Interest * Time of interest

Here the Principal amount is the amount that is deposited and over which we will be receiving our interest.

We all know the rudimentary rule of solving any question is that the units and dimensions of the variables and values should be correct. It means that when we are solving any question where the unit being used is different from the required one, we need to perform unit conversion to get the necessary unit.

When it comes to Simple Interest, the variable unit is time, that is, it can be in hours, days, weeks, months, or years. The rate of interest is generally given in "per annum" which means 'per year.' Therefore we need the unit of time in the year or according to the unit in which rate is given to us.
