-16/5, 8, -20. What is the next term of the geometric sequence.

The nth term of a geometric sequence is expressed as:

Tn = ar^n-1

From the sequence:

a is the first term = -16/5

n is the number of term = 4(since next term is 4th term

r is the common ratio = (8)÷(-16/5) = 8×-5/16

r = -5/2

Substitute the given values into the formula

T4 = -16/5(-5/2)^4-1

T4 = -16/5(-5/2)³

T4 = -16/5×-125/8

T4 = -16/8×-125/5

T4 = -2×-25

T4 = 50

Hence the next term is 50

Step-by-step explanation:

Step-by-step explanation:

Amount borrowed=400

interest rate=4%

Amount of interest after x years =0.04XxX400=$16x

Total to be paid back=400+0.04XxX400=400+16(1)

1) the amount of interest.if Franco pays back the loan in x=1 years is

16x1=$16

2) the amount of interest,if Franco pay back the loan in x=2 years is,

16x2=$32

3) the amount of franco will pay the lender after 2 years will be

400+(16x2)=400+32=$432

Answer:

0.14

Step-by-step explanation:

To get this, you need to divide the number by a 100.

14/100 = 0.14

Therefore 14% is 0.14 as a decimal.

Answer:

16

Step-by-step explanation:

Let us take the number be x . So the three fourths of the number will be , ¾ x . And this is equal to 10. So , According to Question ,

⇒ 3x/4 -2 = 10

⇒ 3x/4 = 10 + 2

⇒ 3/4 x = 12

⇒ x = 12 * 4/3

⇒ x = 16 .

To figure out this problem, let's set up an equation first to make it easier:

702.50 = 5.5x + 70

x = amount charged per hour

702.50 = 5.5x + 70

-70                   -70

-----------------------------

632.5 = 5.5x

/5.5       /5.5

--------------------

115   =   x

Owen was charged $115 per hour

Answer:

x=−8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−7(x+5)=21

(−7)(x)+(−7)(5)=21(Distribute)

−7x+−35=21

−7x−35=21

Step 2: Add 35 to both sides.

−7x−35+35=21+35

−7x=56

Step 3: Divide both sides by -7.

−7x/−7 = 56/−7

x=−8

Answer:-

Distributed: -7x+(-35)=21    Simplified: x=-8

Step-by-step explanation:-

Distributed:

-7(x+5)=21

(x*(-7))+(5*(-7))=21

-7x+(-35)=21

Simplified:

-7x-35=21

-7x=21+35

-7x=56

x=-8

Answer:

Incorrect

Step-by-step explanation:

The correct answer is A.

The slope-intercept form is y-y₁=m(x-x₁)

The problem with B is that if you take out the coordinates for x₁ and y₁, you get the coordinates (1,4). This coordinate does not land on the line.

The coordinates for A is (-1,4). This point does land on the line.

Answer: The tower's shadow is 60 feet long.

Step-by-step explanation:

We can use a ratio to solve this:

24/45 = 32/x

Cross multiply: (Numerator of left side times the denominator of right side, and denominator of the left side by numerator of right side.)

24x = 32(45)

24x = 1440  divide both sides by 24

x = 60

Step-by-step explanation:

Answer:

a = 3, b = 1, c = - 3

Step-by-step explanation:

Substitute n = 1, 2, 3 into the n th term

a + b + c = 1 → (1)

4a + 2b + c = 11 → (2)

9a + 3b + c = 27 → (3)

Subtract (1) from (2) term by term to eliminate c

Subtract (2) from (3) term by term to eliminate c

3a + b = 10 → (4)

5a + b = 16 → (5)

Subtract (4) from (5) term by term to eliminate b

2a = 6 ( divide both sides by 2 )

a = 3

Substitute a = 3 into (4) and evaluate for b

3(3) + b = 10

9 + b = 10 ( subtract 9 from both sides )

b = 1

Substitute a = 3, b = 1 into (1) and evaluate for c

3 + 1 + c = 1

4 + c = 1 ( subtract 4 from both sides )

c = - 3

Then a = 3, b = 1 and c = - 3

The measure of a, b and c is  3, 1 and - 3 respectively.

A quadratic sequence is a sequence whose nth term is given by the general formula -

A{n} = an² + bn + c.

Given are the 4 terms of the quadratic sequence as 1, 11, 27 and 49.

Now, we can the following equations as -

A{1} = a + b + c = 1

a + b + c = 1

c = 1 - a - b              ........ Eq[1]

A{2} = 4a + 2b + c = 11

4a + 2b + c = 11

c = 11 - 4a - 2b           ........ Eq[2]

A{3} = 9a + 3b + c = 27

9a + 3b + c = 27

c = 27 - 9a - 3b               ........ Eq[3]

A{4} = 16a + 4b + c = 49

16a + 4b + c = 49

c = 49 - 16a - 4b             ........ Eq[4]

Equate Eq[1] and Eq[2] -

1 - a - b  =  11 - 4a - 2b  

1 - 11 = - 4a - 2b + a + b

- 10 = - 3a - b

3a + b = 10                ........... Eq[5]

Equate Eq[3] and Eq[4] -

27 - 9a - 3b = 49 - 16a - 4b  

- 9a - 3b + 16a + 4b = 49 - 27

7a + b = 22          .......... Eq[6]

We can write -

7a + 10 - 3a = 22

4a + 10 = 22

4a = 12

a = 3

and

b = 10 - 3a

b = 10 - 9

b = 1

At last -

c = 1 - a - b

c = 1 - 3 - 1

c = - 3

Therefore, the measure of a, b and c is  3, 1 and - 3 respectively.
