Graph the line with slope 3 and y-intercept -3

Answer:

a) 3, 6, 9, 12, 15,...,[tex]3\cdot n[/tex], b) 4, 7, 10, 13, 16,...,[tex]3\cdot n +1[/tex], c) Both sequences are arithmetic.

Step-by-step explanation:

a) The sequence of natural numbers which are multiplied by 3 are represented by the function [tex]f(n) = 3\cdot n[/tex], [tex]n\in \mathbb{N}[/tex]. Let see the first five elements of the sequence: 3, 6, 9, 12, 15,...

b) The sequence of natural numbers which are multiplied by 3 and added to 1 is represented by the function [tex]f(n) = 3\cdot n + 1[/tex], [tex]n\in \mathbb{N}[/tex]. Let see the first five elements of the sequence: 4, 7, 10, 13, 16,...

c) Both sequences since differences between consecutive elements is constant. Let prove this statement:

(i) [tex]f(n) = 3\cdot n[/tex]

[tex]\Delta f = f(n+1) -f(n)[/tex]

[tex]\Delta f = 3\cdot (n+1) -3\cdot n[/tex]

[tex]\Delta f = 3[/tex]

(ii) [tex]f(n) = 3\cdot n +1[/tex]

[tex]\Delta f = f(n+1)-f(n)[/tex]

[tex]\Delta f = [3\cdot (n+1)+1]-(3\cdot n+1)[/tex]

[tex]\Delta f = 3[/tex]

Both sequences are arithmetic.

Answer/Step-by-step explanation:

Since 320 is 10 times 32. The answer for 320 divided by 4 is going to be 10 times the answer of 32 divided by 4.

320 ÷ 4 = 80

32 ÷ 4 = 8

As 320 is 10 times of 32 then values results also 10 times.

One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.

Given:

We have to divide 32 by 4.

The division is as follow:

= 32/4

= (4 x 8)/ 4

= 8

If we multiply 10 to 32 then we get 320.

Then, if we multiply 10 to 8 we get

= 10 x 8

= 80

Step-by-step explanation:

Answer:

x=y

Step-by-step explanation:

Because, if the beams are parallel, <x & <y will be alternate angles which are equal in measure. So, In reverse way, if x=y, then the beams will be parallel.

Answer:

3x^2-4x+8 (R -1)

Step-by-step explanation:

We can use synthetic division:

-2 | 3 2 0 15

____-6 8 -16

     3 -4 8 | -1

So basically, you solve x+2=0 (which is x=-2) and then you put it on the left side. Then make a line and put the coefficients of the polynomial you want to divide. Then with the first coefficient it gets dropped. You would then multiply this by -2 (so 3*-2=-6) and then combine it with 2 in the second column (2+-6=-4). Then we do the same thing with the third column (-4*-2=8) and combine (0+8=8). Same with the fourth column (8*-2=-16) but when we combine this time the answer will be our remainder (15+-16=-1).

So how you would read your final answer is 3x^2-4x+8 (R -1) which the numbers you get are the coefficients.

Step-by-step explanation:

The probability of rolling a 5 for John is 16.666 percent. Because there is 5 other numbers , it is possible but you would have to add all numbers together and then divide it with 100 cause that’s will be how much the percent would be. So you would divide 100 with 6 and then the answer is 16.666 which is also the percentage for John to roll the dice and get a 5.

Answer:

the length is 22 and the width is 18

Step-by-step explanation:

The perimeter is 2(l) + w(2)

w is the width and l is the length

if you plug in 22 and 18 you get

2(22)+(2)18

then you do multiplication to get

44+36

then you add and you get 80

Step-by-step explanation:

Here, we want to get the value of the new size after reduction

We start with reduction amount

That will be;

15/100 * 18 = 2.7 oz

So we now get what it can hold

That’s;

18-2.7 = 15.3 oz

Answer:

-16¹/₂ feet per second

Step-by-step explanation:

average change in altitude in feet per second = change in altitude in feet/change in time in seconds

= -41¹/₄ ft ÷ 2¹/₂ s

= -165/4 ft ÷ 5/2 s

= -165/4 × 2/5 ft/s

= -33/2 feet per second

= -16¹/₂ feet per second

Answer:

Option (4)

Step-by-step explanation:

If ΔLMN is similar to ΔQRS,

Their corresponding sides will be proportional.

[tex]\frac{LM}{QR}= \frac{MN}{RS}= \frac{LN}{QS}[/tex]

[tex]\frac{5}{6}= \frac{3}{4}= \frac{6}{7}[/tex]

But it's not true.

Therefore, the given triangles ΔLMN and ΔQRS are not similar.
