So for this problem, the x-axis is the horizontal line in the center.

Go to where -2 is on the x-axis as shown. Use your finger to trace along since that's usually helpful in finding the point.

Move your finger from -2 on the x-axis to where the solid black line is. On the right side of that, you can see that the y-axis holds the number 2 which is what the y equals for this solid line.

Therefore, the answer should be c.) y = 2

Match the term on the left with its image or description on the right. diameter A) a piece of the circumference of a circle circ

prohojiy [21]

Answers:
Diameter - B)
Circumference - F)
Radius - C) or E)*
Secant - E) or C)*
Concentric circles - D)
Arc - A)

* Please, note that you described option C and option E with the same exact words. One of the two is supposed to be different.

Let's see the definition of each term of the list on the left in order to find the right description:

Diameter = any segment connecting two points on a circle passing through its center. Therefore, the correct description is B) a segment between two points on a circle that passes through its center.

Circumference = length of the distance around the circle (it's a sort of perimeter of the circle). Therefore, the correct description is F) the distance around a circle

Radius = constant distance from the center to any point on the circle. Therefore, the correct description is C/E) a line segment connecting the center C and a point B on the circle.

Secant = a line that intersects a circle at any two points. Therefore the correct description is E/C) Circle A and a line segment connecting the points B and C which are both on the circle.

Concentric circles = two circles positioned such as the center of the first one coincides with the center of the second one. Therefore the correct description is D) Two circles that share the same center.

Arc = part of the curve along the perimeter of a circle. Therefore, the correct description is A) a piece of the circumference of a circle.

Consider the arithmetic sequence 13, 24, 35, ....

MArishka [77]

Answer:

The explicit form for the sequence is: $a_{n}=13+(n-1)(11)$

Step-by-step explanation:

In order to find an explicit form for the given sequence, you have to use the definition of arithmetic sequence and the explicit formula.

An arithmetic sequence is defined as a sequence where the difference of two consecutive terms is a constant.

The explicit formula is:

$a_{n}=a_{1} + (n-1)d$

Where a1 is the first term, d is the common difference and an is the nth term of the sequence.

You have to subtract two consecutive terms to obtain d:

24-13= 11

35-24=11

Therefore d=11

In this case a1=13

Replacing in the formula:

$a_{n}=13+(n-1)(11)$

What is The 7th term of the following sequence?

Natalka [10]

Answer:

0.03125

Step-by-step explanation:

Note that -32 is obtained by multiplying 128 by -1/4, and that 8 is obtained in the same way. Thus, the common ratio is -1/4, and the formula for the nth term of this sequence is

a(n) = 128(-1/4)^(n-1).

Then the 7th term is a(7) = 128(-1/4)^(7-1) = 128(-1/4)^6, or 0.03125.
