Answer:

Yes, it does.

Step-by-step explanation:

Every regular shaped figure will have rotational symmetry, since they are built with identical segments all around.

To find the answer, ask yourself « If I rotate the shape, is there a time where I’ll find the exact same shape again with a different angle? »

So, a square has rotational symmetry, but not a rectangle.

A equilateral triangle has rotational symmetry, but not any other type of triangle.

Complete the equation and tell the which property you used? 8x (14+7) =

otez555 [7]

Answer:

168x.

Step-by-step explanation:

We use the distributive property.

8x (14+7) = 8x*14 + 8x * 7

= 112x + 56x

= 168x

Which geometric series converges?

kvv77 [185]

Answer:

Option (1)

Step-by-step explanation:

In a geometric series,

$\sum_{n=0}^{\infty}ar^n=a+ar^1+ar^2+....$

Here r = $\frac{a_n}{a_{n-1}}$

For |r| < 1, series will converge.

For |r| > 1, series will diverge.

Option (1)

Given geometric series is,

$\frac{1}{2}+\frac{1}{4}+ \frac{1}{8}+ \frac{1}{16}.......$

Common ratio = $\frac{\frac{1}{4}}{\frac{1}{2} }$

= $\frac{1}{2}$

Since, $\frac{1}{2}$

Series will converge.

Option (2)

$\frac{1}{2}+1+2+4+......$

r = $\frac{1}{\frac{1}{2}}=2$

Since, 2 > 1,

Series will diverge.

Option (3)

$\frac{1}{2}+ \frac{3}{2}+ \frac{9}{2}+ \frac{27}{2}+......$

Common ratio 'r' = $\frac{\frac{3}{2} }{\frac{1}{2} }=3$

Since, 3 > 1,

Series will diverge.

Option (4)

$\frac{1}{2}+3+18+108+.....$

Common ratio 'r' = $\frac{3}{\frac{1}{2}}=6$

Since, 6 > 1

Series will diverge.

Therefore, Option (1) will be the correct option.

Which of the following is equation of a line that passes through the point (2,5) and (4,3)

BartSMP [9]

Step-by-step explanation:

The correct answer is C as it has the same line of equation. We can make this clear by verifying that these two points make the same equation or not. So as we can see if we calculate the gradient using the formula y2 - y1 / x2 - x1.
