How do I know if an equation has one solution no solution or infinitely many solutions?

Answers

Answer 1

Answer:  If the equation ends with a false statement (ex: 0=3) then you know that there's no solution. If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.

In a Sequence the first term is 8 and the common difference is -5 the fifth term in the sequence is

Answers

Answer:

[tex]a_5=-12[/tex]

Step-by-step explanation:

Given that,

The first term of the sequence, a = 8

Common difference, d = -5

We need to find the fifth term of the sequence.

The nth term of the sequence is given by :

[tex]a_n=a+(n-1)d[/tex]

Put n = 5, a = 8 and d = -5 in the above formula

[tex]a_5=8+(5-1)(-5)\\\\=8+4(-5)\\\\=8-20\\\\=-12[/tex]

So, the fifth term of the sequence is -12.

Hope this helps!:)

Answer: 104°

Step-by-step explanation:

In a triangle, the total or the interior angles will always be 180°

51° + 25° = 76°

180° - 76° = 104°

Therefore, the answer is 104°

Find the length of leg a in a right triangle with leg b= 4 and hypotenuse C =5


Answers

Answer:

Leg A = 3

Step-by-step explanation:

You use the equation A squared plus B squared equals C squared. Then, you substitute the value that you have, so the equation would be a squared plus 3 squared equals 5 squared. Next, you square the two values to make the equation a squared plus 16 equals 25. After that, you subtract one of the values (which in case is 16) on both that leg value and the hypotenuse, so you are left with A squared equals 9. Finally, you square both 9 and A squared and you are left with A = 3. I hope that helps you understand it clearly!

Answer: g>_-5

Step-by-step explanation:

The inequality g ≥ -5 represents the solutions to the compound inequality.

What is linear inequality? What is the law of Reversal and law of Trichotomy? What is a mathematical equation and expression?Linear inequalities are defined as expressions in which two linear expressions are compared using the inequality symbols.y > mx + cy < mx + cy ≥ mx + cy ≤ mx + cReversal property : If (a > b) then (b < a) and  if (a < b) then (b > a).Law of Trichotomy : The "Law of Trichotomy" says that - only one of the following is true : (a < b) or (a = b) or (a > b).A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.

We have the following inequality -

4 + g ≥ 3

6g ≥ - 30

We can write -

4 + g ≥ 3

g ≥ -1

and

6g ≥ - 30

g ≥ - 5

Therefore, the inequality g ≥ -5 represents the solutions to the compound inequality.

Find the future value if £1500 is invested for 5 years at 8.7% p.a.

Answers

Answer:

$2,152.50

Step-by-step explanation:

A = $2,152.50

I = A - P = $652.50

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8.7%/100 = 0.087 per year.

Solving our equation:

A = 1500(1 + (0.087 × 5)) = 2152.5

A = $2,152.50

The total amount accrued, principal plus interest, from simple interest on a principal of $1,500.00 at a rate of 8.7% per year for 5 years is $2,152.50.

what is the smallest number of integer kilogram weights needed to weigh every whole kilogram between 1kg and 40kg?​

Answers

9514 1404 393

Answer:

  4

Step-by-step explanation:

We assume you are using a balance, and that weights can be put in either pan. In that case, weight values can be either added or subtracted, so there are 3 possibilities for the contribution each weight makes. In other words, we need to find how many digits are required to count to 40 in base 3.

The largest 3-digit number in base 3 is ...

  3^2 +3^1 + 3^0 = 13 (base 10)

The largest 4-digit number adds 3^3 = 27 to this: 27 +13 = 40.

Hence, we can weigh values 0 to 40 using 4 weights, of sizes 1, 3, 9, 27.

__

Some example weights are ...

  5 = 9 - 3 - 1

  38 = 27 + 9 + 3 - 1

where the "negative" weights are placed in the same pan as the unknown.

In January of 2003, Jaylen deposited $1,450 into an investment account earning 5% interest, compounded semiannually. If there are no other deposits or withdrawals from the account, find the total interest earned by the end of December in 2017.

Answers

1450*1.05^30=$6266.816444
= my final answer is

=$6266.82

The amount generated at the end of December 2017 is [tex]\$ 3.04\times 10^{19}[/tex].

Compound Interest

The interest generated in a certain time interval on a particular sum is compounded with the principal sum to generate the interest for given time intervals is called the compound interest. The formula for the compound interest is given below.

[tex]A = p(1+\dfrac{r}{n})^{nt}[/tex]

Where A is the final amount, P is the initial principal sum, r is the interest rate, n is the number of times interest applied per time period and t is the number of time periods.

Given that the principal sum is $1,450, the interest rate is 5%, the time period is 15 years, the number of times interest applied per time period is 2(semiannually = twice in a year).

Hence the amount generated at the end of Dec 2017 is,

[tex]A = 1450 \times (1 + \dfrac {5}{2})^{2\times 15}[/tex]

[tex]A = 1450 \times 2.09\times 10^{16}\\ [/tex]

[tex]A = 3.04\times 10^{19}[/tex]

Hence we can conclude that the amount generated at the end of December 2017 is [tex]\$ 3.04\times 10^{19}[/tex].

Answer:

The total cost =  $714

Step-by-step explanation:

Given

Monitor cost = $287Scanner cost = $58Keyboard cost = $49Printer cost = $320

The total cost can be determined by adding the costs of all the pieces of equipment.

Thus,

Total cost = Monitor cost + Scanner cost + Keyboard cost + Printer cost

                = $287 + $58 + $49 + $320

                = $714

Therefore, the total cost =  $714
