How do you do geometric sequences?

1 answer:

Ostrovityanka [42]3 years ago

4 0

Answer:

By multiplying. for example,

2*2=4

4*2=8

8*2=16

So, as we are multiplying, the value are increasing and the common ratio between them is 2 cause they all are multiplying by 2 and the geometric sequence for this one will be: 2,4,8,16......

Stitu wants to cut square pieces of chart paper which is 48 cm long and 32 cm wide .If she is able to get 6 equal pieces ,then f

alisha [4.7K]

Answer:

Length of each piece = 16cm.

Step-by-step explanation:

Since the chart paper is 48cm x 32cm in size, finding the total area of the paper would be A = l x w, where l=length of the paper and w=width.

A = 48 x 32 = 1536cm²

Since Stitu was able to get 6 equal pieces, then we can take the total area and divede by 6:

$\frac{1536}{6} = 256$

Since 256cm² represents the area of each square, we can take the square root of this number to find the length of just one square since the formula for the area of a square is A=s², where s=the length of one side:

s² = 256 so √s² = √256 or s = 16cm

Suppose m is in the line given by the equation 6x-3y=7, and suppose n is the line perpendicular to m and passing Nd through the

stealth61 [152]

Answer:

The x co-ordinate o intersection of line k and n is $\frac{8}{11}$

Step-by-step explanation:

Given as :

The equation of line m is 6 x - 3 y = 7

So, in the standard form , line equation is

y = a x + c , where a is the slope

So, 6 x - 3 y = 7 can be written as

3 y = 6 x - 7

or, y = 2 x - $\frac{7}{3}$ ........1

So, slope of this line = a = 2

Now, The line n is perpendicular to line m and passing through line ( 6 , 2 )

So, Slope of line n = b

For , perpendicular lines , products of slope = - 1

Or, a × b = -1

∴ b = - $\frac{1}{a}$

I.e b = - $\frac{1}{2}$

So,equation of line n with slope b and passing through line ( 6 , 2 ) is

y - $y_1$ = b ( x - $x_1$ )

or, y - 2 = - $\frac{1}{2}$ ( x - 6 )

or, 2 × ( y - 2 ) = - 1 ( x - 6 )

or, 2 y - 4 = - x + 6

or, x + 2 y -10 = 0 ........2

Again, equation of line k with slope 5 and y intercept = 1

For y intercept , x coordinate = 0

y = c x + c

or, 1 = c× ( 0 ) + c

Or, c = 1

Or, equation of line k is

y = 5 x + 1 ..........3

Now intersection of line k and n is

put the value of y from eq 3 into eq 2

I.e x + 2 × ( 5 x + 1 )-10 = 0

Or, x + 10 x + 2 - 10 = 0

or, 11 x - 8 = 0

or 11 x = 8

∴ x = $\frac{8}{11}$

Hence The x co-ordinate o intersection of line k and n is $\frac{8}{11}$ Answer
