Answer:

The given sequence is an arithmetic sequence.

Step-by-step explanation:

Given sequence is:

7, 10, 13, 16, ...

Here

a_1 = 7\\a_2 = 10\\a_3 = 13\\a_4 = 16

In order for a sequence to be an arithmetic sequence the common difference between the consecutive terms of the sequence should be same. Common difference is denoted by d.

So,

d = a_2 - a_1 = 10-7 = 3\\d = a_3 - a_2 = 13-10 = 3\\d = a_4-a_3 = 16-13 = 3

As we can see that the common difference is same for consecutive terms.

The given sequence is an arithmetic sequence.

If a diameter intersects a chord of a circle at a right angle, what conclusion can be made?
drek231 [11]

Answer:

The chord is bisected.

Step-by-step explanation:

see the attached figure to better understand the problem

In the circle of the figure

The diameter is the segment DE

The chord is the segment AB

PA=PB=r ----> radius of the circle

Triangles PAC and PBC  are congruent right triangles by SSS

Because

PA=PB

PC is a common side

AC=BC ----> Applying Pythagoras Theorem

therefore

The chord AB is bisected

7 times what equals 1?
Arturiano [62]
For this case, the first thing we must do is define a variable.
 We have then:
 x: unknown number
 Doing the multiplication we have:
 (7) (x) = 1

 From here, we clear the value of x.
 We have then:
 x =  \frac{1}{7} 

 Therefore, we have:
 (7) ( \frac{1}{7} ) = 1

 Answer:
 
7 times 1/7 equals 1
