Answer:

Option C. (n + 1)/(n +2).

Step-by-step explanation:

The given sequence is 2/3, 3/4, 4/5, 5/6, 6/7.

and we have to find the general term of the given sequence.

Since first term of the sequence is 2/3

So numerator can be represented as (n + 1) and the denominator as (n + 2)

Therefore the general term will be (n + 1)/(n + 2)

Option C is the answer.

P = the principal

t = 25 years the time in years

r = 0.0525 or 5.25% annual rate

m = 1 compounding periods per year

i = 0.0525 or 5.25% interest rate per period

n = t*m = 25 total number of compounding periods

A = $75,000 future value

A = P(1 + i)^n

P(1 + i)^n = A

P(1 + 0.0525)^25 = 75000

by solving we find:

P = $20,869.34

Answer:

Options A & B

Step-by-step explanation:

Given is a triangle XYZ in the I quadrant.  There are four more triangles A, B,C and D given.

We have to find that which one is the translation of XYZ

We know that by translation we must get a congruent triangle as XYZ.

By simply seeing we can say that C and D are not congruent with XYZ.

So these two are eliminated

Remaining are A and B.

Both A and B are right

This is because XYZ is transformed into B by shifting 7 units horizontal to the left.

A is the reflection of B about x=-5.5

Thus both A and B are right

Laplace transformation is the transformation in the integral form which convert a function of a real variable to a complex variable.

The Laplace transform of the given function is,

Answer:

The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).

Step-by-step explanation:

To see if the answer to an equation is right, you just have to put the value of X and Y into the equation system, since we don´t have the equation system that the student used, we will make our own, so we will start by stating that Notebooks are represented by X and index cards are represented by Y.

Your equation would look like this:

3x+ 4y=34

The student said that the price of the notebook is $5 and the index card would be $1, now we put those values into the equation.

3(5)+4(1)=32

15+4=32

19=32

Since 19 is not equal to 32, the equation is wrong, therefore the student is wrong.

Now to solve it you get your other equation, since if he had bought 5 and 5 he would have needed 18 extra dollars that means that

5x+5y= 32 +18

5x+5y=50

With the two equations you just use elimination process to create a single equation:

(5x+5y=50)-3=  -15x-15y=-150

(3x+4y=32)5 =   15x+20y= 160

You eliminate the x from the equation and are left with:

-15y+20y= -150+160

5y=10

y=[tex]\frac{10}{2}[/tex]

y=2

Now that you have the value of Y you just put it into the equation to know the value of x:

5x + 5(2) = 50

5x+10=50

You clear the x and the result would look like this:

x= [tex]\frac{50-10}{8}[/tex]

x=8

The correct option is:

4(3x² + 1)(x – 5)

To find the completely factored form of the expression 12x³ – 60x² + 4x – 20, we can first factor out the greatest common factor, which is 4.

4(3x³ – 15x² + x – 5)

Next, we can factor the quadratic expression 3x³ – 15x² + x – 5 by grouping:

4[3x²(x – 5) + 1(x – 5)]

4(3x² + 1)(x – 5)

Therefore, the completely factored form of 12x³ – 60x² + 4x – 20 is:

4(3x² + 1)(x – 5

So, the correct option is:

4(3x² + 1)(x – 5)

Answer: The explicit rule for the sequence will be

[tex]a_n=15.5-2.5n[/tex]

Step-by-step explanation:

Since we have given that

[tex]13,10.5,8,5.5,3,0.5.....[/tex]

Here,

a = first term = 13

d = common difference

[tex]a_2-a_1 = 10.5-13=-2.5[/tex]

Since it forms an A.P. ;

[tex]a_n=a+(n-1)d\\\\a_n=13+(n-1)(-2.5)\\\\a_n=13-2.5n+2.5\\\\a_n=15.5-2.5n[/tex]

Hence, the explicit rule for the sequence will be

[tex]a_n=15.5-2.5n[/tex]

The question is about solving a system of equations to find the number of nickels and dimes in a piggy bank, given a total amount and quantity of coins. The solution involves using either the substitution or elimination method to find the values of the two variables representing nickels and dimes.

Explanation:

The question involves solving a system of equations to find the number of nickels and dimes in Keana’s piggy bank. Given the total amount is $4.30 and there are 59 coins in total, we can set up the following equations:

Let N represent the number of nickels and D the number of dimes.

The value equation is 0.05N + 0.10D = 4.30 or 5N + 10D = 430

The quantity equation is N + D = 59.

To solve these equations, we will use the substitution or elimination method. First, solve the quantity equation for one variable, for example, N = 59 - D. Then, substitute this expression for N in the value equation and solve for D. After finding D, substitute its value back into any of the original equations to find N. The sum of the digits in the number of nickels in Keana's bank is then found by adding together the digits of N.

we get,  5(59 - D) + 10D= 430

295 - 5D + 10D = 430

5D = 135 , Therefore D = 27

and N = 59 - D = 59 - 27 = 32.

To find the sum of the digits in the number of nickels (n=32), we add the digits 3+2=5

Therefore, the sum of the digits in the number of nickels in Keana’s bank is 5.

Answer:

(D)

Step-by-step explanation:

Given: Triangle ABC is a right triangle. Point D is the midpoint of side AB and point E is the midpoint of side AC. The measure of angle ADE is 28°.

To prove: The measure of angle ECB is 62°.

Proof:

Step1. Segment DE joins the mid points of segments AB and AC (GIVEN).

Step 2. Segment DE is parallel to segment BC (MIDSEGMENT THEOREM)

Step3. Angle ECB is congruent to angle AED (CORRESPONDING ANGLES ARE CONGRUENT) that is ∠AED≅∠ACB.

Step 4. Measure of angle DAE is 90° (Definition of right angle)

Step 5.  Measure of angle ADE is 28° (Given)

Step 6. Thus, by triangle sum theorem, we have

∠DAE+∠ADE+∠AED=180°

∠AED=180-118

∠AED=62°

Step 7. Thus, by substitution, we have

∠AED≅∠ACB that is ∠ECB=62°

Hence proved.

Final answer:

The number that, when multiplied by itself 4 times equals 81, is 3, as 3 to the fourth power (3^4) is 81.

Explanation:

To find what number multiplied by itself 4 times equals 81, we need to find the fourth root of 81. The fourth root is the same as raising a number to the 0.25 power. To calculate manually, we may take two square roots in succession, since the square root of a number squared is the original number. The square root of 81 is 9, and the square root of 9 is 3, thus the fourth root of 81 is 3. Indeed, 34 = 3 × 3 × 3 × 3 = 81.

Answer:

Option 2 is correct.

Step-by-step explanation:

In the given graph x-axis represents the numbers and y-axis represent the frequency.

Number         Frequency              Cumulative frequency

100                        14                              14

200                       6                               20   (20<36)

300                       18                              38  (38>36)

400                       12                              50

500                       2                               52

600                       12                              64

700                       8                               72

Total                     72          

Mode is the number which has highest frequency. From the above table it is noticed that the highest frequency is 18 at 300. Therefore mode of the data is 300.

Sum of frequency is 72, which is an even number.

[tex]Median=\frac{n}{2}\text{th term}[/tex]

[tex]Median=\frac{72}{2}\text{th term}[/tex]

[tex]Median=36\text{th term}[/tex]

We have to find the number whose cumulative frequency is more than 36 but preceding cumulative frequency is less than 36.

Median of the graph is 300.

Since the value of median and mode are same, therefore

[tex]median=mode[/tex]

Option 2 is correct.
