If the first term of AP is 4 and the sum of first five term is equal to one-fourth of the sum of the next five term, then find the 15th term?​

Answers

Answer 1

Answer:

15th term = 116

Step-by-step explanation:

a= 4

Sum of an A.P = n/2 {2a + (n-1)d}

sum of first five term is equal to one-fourth of the sum of the next five term

5/2{ 2*4 + (5-1)d} = 1/4 × 10/2{2*4 + (10-1)d

5/2 {8 + 4d} = 1/4 × 5{ 8 + 9d}

40/2 + 20/2d = 1/4{ 40 + 45d)

20 + 10d= 40/4 + 45/4d

20 + 10d = 10 + 45/4d

20 - 10 = 45/4d - 10d

10 =45d - 40d /4

10 = 5/4d

Divide both sides by 5/4

10 ÷5/4 = d

10×4/5 = d

40/5 = d

8 = d

d= 8

Find the 15th term

15th term = a + (n-1)d

= 4 + (15-1)8

= 4 + (14)8

= 4 + 112

= 116

The 15th term is 116

Domain: [tex](-\infty,\infty)[/tex]

Range: [tex](1,\infty)[/tex]

Step-by-step explanation:

The domain of a function is the span of x-values it covers.

The range of a function is the span of y-values it covers.

From the graph, we can see that the domain stretches infinitely in both directions. Therefore, the domain is all real numbers.

In interval notation, this is:

[tex](-\infty,\infty)[/tex]

For the range, note that horizontal line at y=1.

The dotted line tells us that there is a horizontal asymptote there. In other words, y would never reach exactly 1.

Thus, our range would be all values greater than 1 (to positive infinity).

In interval notation, this is:

[tex](1,\infty)[/tex]

Step 1: Simplify both sides of the equation.

6x−5=(2)(3)x+4

6x+−5=6x+4

6x−5=6x+4

Step 2: Subtract 6x from both sides.

6x−5−6x=6x+4−6x

−5=4

Clare had $110 in her saving. She wanted to buy an MP3 player for $ 118 what is the difference between how much money Clare had and how much she needed

Answers

Answer:

$8

Step-by-step explanation:

We want to find the difference between the money Clare has and the money she needs.

Difference means subtract, so we should subtract the amount of money she has from the amount she needs.

money needed - money she has

She has $110 and she needs $118 to purchase the MP3 player.

$118 - $110

Subtract 110 from 118.

$8

The difference between the money Clare has and the money she needs is 8 dollars.

Is it true that ƒ −(g − h) = (ƒ − g) − h? Explain why you believe the equation is true or provide a counterexample to show that it is not.

Answers

Answer:

The expression is false

Step-by-step explanation:

Given

[tex]f - (g - h) = (f - g) - h[/tex]

Required

True or False

To determine if the expression is true or false, we need to simplify both sides of the equation

[tex]f - (g - h) = (f - g) - h[/tex]

Start by opening the bracket on the right hand side

[tex]f - (g - h) = f - g - h[/tex]

Then open the bracket on the left

[tex]f - g + h = f - g - h[/tex]

Subtract f - g from both sides

[tex]f - g - (f - g) + h = f - g - (f - g) + h[/tex]

[tex]f - g - f + g + h = f - g - f + g - h[/tex]

[tex]f - f - g + g + h = f - f - g + g - h[/tex]

[tex]h \neq -h[/tex]

Hence;

The statement is false

To further check;

Assume f = 5; g = 4 and h = 3

[tex]f - (g - h) = (f - g) - h[/tex] becomes

[tex]5 - (4 - 3) = (5 - 4) - 3[/tex]

[tex]5 - 4 + 3 = 5 - 4 - 3[/tex]

Find the distance between the points (2,-9) and (-1,4)

Answers

Answer:

The answer is

[tex]\sqrt{178} \: \: or \: \: 13.34 \: \: units[/tex]

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(2,-9) and (-1,4)

The distance between them is

[tex]d = \sqrt{ ({2 + 1})^{2} + ({ - 9 - 4})^{2} } \\ = \sqrt{ {3}^{2} + ({ - 13})^{2} } \\ = \sqrt{9 + 169} \\ [/tex]

We have the final answer as

[tex] \sqrt{178} \: \: or \: \: 13.34 \: \: units[/tex]

Hope this helps you

Answer:

[tex]\sqrt{178}[/tex] ≈ 13.3

Step-by-step explanation:

Calculate the distance using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (2, - 9) and (x₂, y₂ ) = (- 1, 4)

d = [tex]\sqrt{(-1-2)^2+(4+9)^2}[/tex]

   = [tex]\sqrt{(-3)^2+13^2}[/tex]

   = [tex]\sqrt{9+169}[/tex]

   = [tex]\sqrt{178}[/tex] ≈ 13.3 ( to 1 dec. place )

What is the value of 3.5 (11) + 1.9 (11) + 1.6 (11)?

Answers

Answer:

77

Step-by-step explanation:

3.5(11)+1.9(11)+1.6(11)

3.5(11)=38.5

1.9(11)=20.9

1.6(11)=17.6

38.5+20.9+17.6

77

Your answer is 77

3.5 x 11 = 38.5

1.9 x 11 = 20.9

1.6 x 11 = 17.6

38.5 + 20.9 + 17.6 = 77

Answer: Line BC and Line DE

Step-by-step explanation:

In geometry terms, we can say that for any set of two points, we always can find a line that passes through them.

For example, in the image, we can see two lines (but actually we could make more with those points)

We can see a line that connects points B and C, and we can call that line as:

Line BC

We also can see a line that connects the points D and E, we can call this line as:

Answers

Answer:

0.6 deg/s²

Step-by-step explanation:

Acceleration is the time rate of change of velocity, it is the ratio of velocity to time. The formula for acceleration is given by:

Acceleration = Change in velocity / time taken = (Final velocity - Initial velocity) / time

Given that the acceleration is 2160 deg/min², we have to convert it to deg/s²

1 min = 60 seconds

1 min² = 60² s² = 3600 s²

[tex]2160\ deg/min^2=\frac{2160\ deg}{1\ min^2*3600\ \frac{s^2}{min^2} }=0.6\ deg/s^2\\ \\2160\ deg/min^2=0.6\ deg/s^2[/tex]

The answer is 5

Step-by-step explanation:

Given g(x)=3x2+3 find x if g(x)=78 = 5

Hope this helped you :)

Answer:

x = ± 5

Step-by-step explanation:

Given

g(x) = 3x² + 3 and g(x) = 78 , then equate the right sides, that is

3x² + 3 = 78 ( subtract 3 from both sides )

3x² = 75 ( divide both sides by 3 )

x² = 25 ( take the square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5

That is x = - 5 or x = 5

Given that f(x) = x2 + x and g(x) = 3x + 1, find the value of g(f(-2)).​

Answers

Answer:

7

Step-by-step explanation:

[tex]f(x) = x^2 + x\\g(x) = 3x + 1\\\\g(f(-2)) = ?\\f(-2) =?\\[/tex]

To find f(-2) , Substitute -2 for x in the given equation ;

[tex]f(-2)= (-2)^2 +(-2)\\f(-2) = 4-2\\f(-2) = 2[/tex]

To find g(f(-2)) ;

[tex]g(f(-2))\\f(-2) =2\\\\= g(f(-2)) = g(2)\\[/tex]

To find g(2) , substitute 2 for x in the given equation

[tex]g(x) = 3x+1\\g(2) = 3(2)+1\\\\g(f(-2)) = 6+1\\\\g(f(-2))=7[/tex]

Value of g(f(-2)) is equals to 7.

What is composition function?

"Composition function is defined as where two function combined together to create a new function. It is denoted by 'o'."

According to the question,

Given,

f(x) = x² + x

g(x) = 3x + 1

Substitute the value x=-2 in function f(x) we get,

f(-2) = (-2)² +(-2)

      = 4 -2

      = 2                                         ______(1)

Again substitute the value of x = f(-2) in g(x) to get composition function,

g(f(-2)) = 3f(-2) +1

Substitute the value f(-2) from (1) we have,

   g(f(-2)) = 3(2) + 1

g(f(-2)) = 7

Hence, value of g(f(-2)) is equals to 7.
