Step-by-step explanation:

Answer:

the y-values for the x-values, starting with -3, are:

-5, -4, -3, -2, -1, 0, 1

Step-by-step explanation:

for each, plug the x-value into the equation y = x - 2 and get the result

example, when x = -3 then y = (-3 - 2) which is -5

Answer:

  (a)  an = 2n -1

  (b)  an = n(n +1)/2

  (c)  an = n^2

Step-by-step explanation:

(a) The odd numbers are an arithmetic sequence with first term 1 and common difference 2. The general term is ...

  an = a1 +d(n -1)

  an = 1 + 2(n -1)

  an = 2n -1

__

(b) The triangular numbers are a quadratic sequence with first term 1, first first difference 2, and second differences 1.

The first few terms and differences are ...

  sequence: 1, 3, 6, 10, 15, 21, 28, ... (a1 = 1)

  first diff: . . . 2, 3, 4, 5, 6, 7, ... (d1 = 2)

  2nd diff: . . . . 1, 1, 1, 1, 1, ... (d2 = 1)

There is a sort of general formula* that can make use of these numbers to give the general term of the sequence:

  an = a1 +(n -1)(d1 +(n -2)/2(d2))

For the values we have, this gives our general term as ...

  an = 1 + (n -1)(2 +(n -2)/2(1))

  an = n(n +1)/2

__

(c) The general term in the sequence of square numbers is simply the square of the term number:

  an = n²

_____

* There are a number of other ways to get to the general formula for triangle numbers. You can search for it, since it is well-known. You can use a quadratic regression tool on the sequence of numbers. You can develop a system of equations to find the coefficients of the quadratic equation.

The general formula given can be used to find polynomial sequences of any degree. Coefficients at successive layers in the formula are of the form (n -k)/k. The first term in parentheses following that is the first k-th difference.

Answer:

Step-by-step explanation:

The answer is.

y = 2, x = -4

Answer:

x=-4

Step-by-step explanation:

First substitute y=3x+14

2x-3(3x+14)=-14

Distribute:

2x-9x-42=-14

Add or subtract like terms

-7x-42=-14

-7x=28

Finally divide both sides by -7

-7x/-7=x

28/-7=(-4)

x=-4

Answer:

The circumference of the CD is approximately 38 cm

Step-by-step explanation:

The circumference of the CD can be seen as the distance around the CD.

The word "circumference"  is used to describe the perimeter of circular objects.

To find an approximate value of the circumference of the CD, we will use this formula.

Circumference = π × diameter

let us take π to be = 3.142

∴ circumference = 3.142 × 12 = 37.6991 cm

we can round this up to teh nearest tenth as 38cm

Answer:

Step-by-step explanation:

No this is not proportional , because the ratio of y/x for each one is not same ,

As for 1st one ,

y/x =4/2 =2

for 2nd one ,

y/x=16/4 = 4 and so on

so they re not equal that's why they are not proportional

Answer:

128 ft^2 needed

Step-by-step explanation:

Given

See attachment for missing details

Required

Determine the number square feet needed

First, calculate the inner area (A1)

[tex]A_1 = Length * Width[/tex]

[tex]A_1 = 20ft * 8ft[/tex]

[tex]A_1 = 160ft^2[/tex]

Next, calculate the outer area (A2)

[tex]A_2 = Length * Width[/tex]

[tex]A_2 = 24ft * 12ft[/tex]

[tex]A_2 = 288ft^2[/tex]

The area of the planter is:

[tex]Area = 288ft^2-160ft^2[/tex]

[tex]Area = 128ft^2[/tex]

Hence, he needs 128 square feet

the angle would be a 90° angle

========================================================

Explanation:

At 3:00 pm, the hour hand is pointed directly at the '3'. At 4:00 pm, the hour hand moves to point directly at the '4'.

Since 3:30 pm is the halfway point of 3:00 pm and 4:00 pm, this must mean the hour hand is halfway between the '3' and '4'.

Each little tiny tickmark on the clock represents 1 minute. From the "3" to "4", we have 5 tickmarks, so half of that is 5/2 = 2.5

The hour hand is pointing to 2.5 minutes after the 15 minute mark, meaning the hour hand is pointing to the 15+2.5 = 17.5 minute mark.

The span of time from 17.5 minutes to 30 minutes is 30-17.5 = 12.5 minutes.

Divide this over 60 minutes and we get 12.5/60 = 125/600 = 5/24

The 5/24 indicates the fractional amount of 360 degrees being taken up by this angle shown.

So, (5/24)*360 = 75 degrees is the angle measure in this diagram.

Answer:

17 to 24

25 to 32

Step-by-step explanation:

8-1=7

16-9=7

therefore it means we add 7 on the next number which is 17; to get 24,and also to the next number after 24 which is 25 to get 32

Answer: 17 to 24 then 25 and 32

[tex]7x + 12 = 9x - 6[/tex]

[tex]7x + 12 - 7x = 9x - 6 - 7x[/tex]

[tex]12 = 2x - 6[/tex]

[tex]12 - 6 = 2x -6 - 6[/tex]

[tex]6 = 2x - 12[/tex]

In pythagoras, c is the hypotenuse. That is AC. Where a is AB and b is BC.

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] {(6 x + 5)}^{2} = {(7x + 12)}^{2} + {BC}^{2} [/tex]

[tex] {((6 \times 9) + 5)}^{2} = {((7 \times 9)}^{2} + 12)^{2} +{BC}^{2} [/tex]

[tex] {(54 + 5)}^{2} = {(63 + 12)}^{2} + {BC}^{2} [/tex]

[tex] {59}^{2} = {75}^{2} + {BC}^{2} [/tex]

[tex]3481 - 5625 = {BC}^{2} [/tex]

Answer: He can buy 12 shooters with $1. 20 red marbles with $1. 300 multicolored marbles.

Step-by-step explanation:

Shooters = 1 dollar is 60 cents

60 divided by 5 = 12

Red = 60 divided by 3

= 20

Multicolored = 60 x 5 because 1 for 5

= 300
