Write an explicit formula for a_n, the nth term of the sequence 4, -20, 100, ...

Answers

Answer:

[tex]a_{n}[/tex] = 4 [tex](-5)^{n-1}[/tex]

Step-by-step explanation:

There is a common ratio r between consecutive terms , that is

r = - 20 ÷ 4 = 100 ÷ - 20 = - 5

This indicates the sequence is geometric with nth term ( explicit formula )

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 4 and r = - 5 , then

Step-by-step explanation:

The area of a rectangle is equal to [tex]A=l\cdot w[/tex], where [tex]l[/tex] is the length of the rectangle and [tex]w[/tex] is the width of the rectangle. In a rectangle, opposite sides are equal.

Therefore, we can write the following system of equations:

[tex]\begin{cases}a\cdot (9+b)=84,\\a\cdot b=21\end{cases}[/tex]

Expand the first equation:

[tex]9a+ab=84[/tex]

Substitute the second equation into the first ([tex]ab=21[/tex]):

[tex]9a+21=84,\\9a=63,\\a=\boxed{7}[/tex]

What is constant of proportionality? I'm still having trouble understanding it. Can someone please give me a give problems and tell me how to find the COP (constant of proportionality) <3 thamks.

Answers

Answer:

See Explanation

Step-by-step explanation:

Given two variables (say x and y); the constant of proportionality is the ratio between these to variables.

Illustration; y is directly proportional to x

The above statement can be represented as:

[tex]y\ \alpha\ x[/tex]

When converted to an equation, you get

[tex]y\ =k x[/tex]

k, in the above equation, represents the constant of proportionality

Divide both sides by x to solve for k

[tex]k = \frac{y}{x}[/tex]

Take for instance: [tex]y = 3x[/tex]

Divide both sides by x

[tex]\frac{y}{x} = 3[/tex] --- 3 is the constant of proportionality

The length of a rectangular plot is 9/2 times that of it's breadth. If the area of the plot is 200
square meters, then what is it's length?

Answers

Answer:

The length of the rectangular plot is 30 m

Step-by-step explanation:

Mathematically, the area of a rectangle is the product of its length and width

Let us have the length as x m ; for the length to be 9/2 of the breadth, it means the breadth is 2/9 of the length

so we have the breadth as 2/9 * x = 2x/9

The product of the two equals the area which is 200 square meters

thus, we have it that;

x * 2x/9 = 200

2x^2 = 9 * 200

x^2 = 1800/2

x^2 = 900

x = √900

x = 30 m

the sum of the two fractions is 9/26. if one of the fraction is 1/13, find the other​

Step-by-step explanation:

let the other fraction be x

1/13 +x =9/26

x = 9/26 - 1/13

take lcm of the denominator . lcm=26

x = 9*1 - 1*2/26

The circumference of a circle is 8.34cm. Find the length of the diameter. Give your answer rounded to 2 DP.

Answers

Answer:

Diameter, D = 2.65 cm

Step-by-step explanation:

Given the following data;

Circumference of circle = 8.34 cm

To find the length of its diameter;

Mathematically, circumference of a circle is equal to;

C = πD

Where;

C is the circumference of a circle.D is the diameter of a circle.Pie, π = 3.142

Substituting into the formula, we have;

8.34 = 3.142 * D

[tex] D = \frac {8.34}{3.142} [/tex]

Diameter, D = 2.65 cm

Find the x-intercept and y-intercept of the graph of the equation 2y = 3x - 6.

Answers

Given:

The equation is:

[tex]2y=3x-6[/tex]

To find:

The x-intercept and y-intercept of the graph of the given equation.

Solution:

We have,

[tex]2y=3x-6[/tex]

Substitute [tex]y=0[/tex] to find the x-intercept.

[tex]2(0)=3x-6[/tex]

[tex]0+6=3x[/tex]

[tex]\dfrac{6}{3}=x[/tex]

[tex]2=x[/tex]

So, the x-intercept of the graph of the given equation is 2.

Substitute [tex]x=0[/tex] to find the y-intercept.

[tex]2y=3(0)-6[/tex]

[tex]2y=-6[/tex]

[tex]y=\dfrac{-6}{2}[/tex]

[tex]y=-3[/tex]

So, the y-intercept of the graph of the given equation is -3.

Therefore, the x-intercept is 2 and the y-intercept is -3.

Find the measure of the missing angles. (someone help this is so urgent [cry])

Answers

Answer:

b=77

c = 103

Step-by-step explanation:

b and 77 are vertical angles and vertical angles are equal

b= 77

c and 77 are supplemental angles and supplemental angles add to 180

c+77 =180

c = 180-77

c =103

[tex] \large \sf \star \: \blue{Answer} \: \star[/tex]

[tex] \small \sf \mapsto\: b = \fbox{77 °} [/tex]

[tex] \small \sf \mapsto \: c = \fbox{ 103 °}[/tex]

Step-by-step explanation:

Here,

Angle b and 77° both are vertical angles . So, both angles are equal . b = 77 °

And,

Angle b and angle c are on straight line so it's supplementary angles and we know that sum of all angles of supplementary angles is 180 °.

So, b + c = 180 °

77° + c = 180 ° ... { b = 77 -( vertical angle )}

subtract 77 from each sides

77 - 77 + c = 180 ° - 77 °

c = 103 °

Answers

Answer:

6) 62.5%

7) 54

8) B

Step-by-step explanation:

For number 6, just add 96 and 160 and then do 160/(96+160), which is equal to 0. 625, or 62.5%.

for number 7, x is always equal to 1/3 of y, so if x is 18, we know that 18 is 1/3 of y. 18x3 is equal to 54, which is your answer.

For number 8, you can see that B is right because it uses the greatest common factor of 32 and 48, which is 16. All the other answers can be simplified more.

Answer:

6. C) 62.5%

7. D) 54

8. B) 16(2c + 3d)

Step-by-step explanation:

160 + 96 = 256

[tex]\frac{160}{256}=\frac{160/32}{256/32}=\frac{5}{8}[/tex]

5 ÷ 8 = 0.625

0.625 × 100

62.5%

GCF = 32

The factors of 160: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

The factors of 256: 1, 2, 4, 8, 16, 32, 64, 128, 256

The GCF is 32.

1:3 = 7:21 = 9:27 = 13:39 = 18:y

[tex]\frac{1}{3}: \frac{18}{y}[/tex]

1 × y = 18 × 3

y = 54

GCF(32, 48)

32 = 2 × 2 × 2 × 2 × 2

48 = 2 × 2 × 2 × 2 × 3

GCF = 2 × 2 × 2 × 2

GCF = 16

It’s really easy do not make it complicated on yourself!

Fist thing you should know ANY NUMBER WHICH IS TO POWER ZERO THE ANSWER WILL ALWAYS BE ONE!!

Part A : (7^2)^x is (49)^x

(49)^x = 1 , here is basically asking you what’s the value of X to know which number to the power of 49 to put so that it equals to 1, obviously the answer is 0 as we said before ANY NUMBER TO THE POWER OF 0 , the answer will be 1

Part A = 0
————————-

Part B IS GONNA BE WAY EASIER NOW TRUST ME!!

(7^0) = 1

(1)^x = 1

So now is asking what number to put for x for you to multiply by one to get one it’s obviously 1, because 1 x 1= 1

Part B = 1

Martha has two jobs. One pays $15 per hour, and she works at that job 10 hours per week. The other job pays $13 per hour, and she works at that job 30 hours per week. How much money does she make per year?




.

Answers

Answer:

$28080 per year

Step-by-step explanation:

15$ per hour for the first job and she does it for 10 hours each week, this means, 15*10 which is 150. So we have 150 for the 1st job every week.

2nd job, 13$ per hour. She does that for 30 hours a week so we have 13*30 which is 390$ per week.

The two jobs together are 150 per week and 390 per week which means 540$ per week. Now` if we want to find how much she makes in a year, the are 52 weeks in a year, so multiply 540$ *52=$28080

So she makes $28080 per year
