What is the common difference of the arithmetic sequence-20,-16,-12,-18

Mathematics
1 answer:
Paul [167]3 years ago
8 0

Answer:

common difference = 4

Step-by-step explanation:

<em><u>common difference</u> is</em><em> </em><em>the difference between the successive term and its preceding term.</em>

let's take the successive term of -20 that is - 16

common difference (d) = successive term - preceeding term

= -16 -(-20)

= -16 + 20

=<u> 4</u>

if we take the successive term of -16 that is -12

we'll get the same common difference.

d = -12 -(-16)

d = -12 + 16

d = 4

this means that the common difference for an AP remains constant.

Passing through (2, - 2) and perpendicular to the line whose equation is y= 5x+2
jonny [76]

Step-by-step explanation:

Hey there!!!

Here,

Given, A line passes through point (2,-2) and is perpendicular to the y= 5x+2.

The equation of a straight line passing through point is,

(y - y1) = m1(x - x1)

Now, put all values.

(y  + 2) = m1(x - 2)

It is the 1st equation.

Another equation is;

y = 5x +2........(2nd equation).

Now, Comparing it with y = mx + c, we get;

m2=5

As per the condition of perpendicular lines,

m1×m2= -1

m1 × 5 = -1

Therefore, m2= -1/5.

Keeping the value of m1 in 1st equation.

(y + 2) =  \frac{ - 1}{5} (x - 2)

Simplify them.

5(y + 2) =  - x + 2

5y + 10 =  - x + 2

x + 5y + 8 = 0

Therefore the required equation is x+5y+8= 0.

Can someone please help me!!!

Answer:

y = sin x/2

​

Step-by-step explanation:

y   =   a.sin.bx

a   =   y max=  2

y   =   a.sin.bx  =  2.sin.bx

sin.bx   =   sin x/2

b=1/2

so

y=sin x/2

look at the picture
