Answer:

10 cm

Step-by-step explanation:

The diameter is a chord (line) that connects on both ends of a circle which includes the center point of the circle. The radius comes from the center point of the circle to one end of the circle.

Diameter is therefore 2 radii (radius).

So if diameter is given and you want to find the radius, divide it by two to find the answer.

20 ÷ 2 = 10 cm

Create a sequence with five terms based on the given information. a. A arithmetic sequence with a third term of 8 and a constant
kolezko [41]

Part a .

A arithmetic sequence with a third term of 8 and a common difference of 5 .

To find the first five therms, since the common difference is 5, so we add 5 to get the fourth term and add 5 to fourth term to get the fifth term .

And for first two terms, we will subtract 5 from 8 to get the second term and subtract 5 from the second term to get the first term. And we will get

8-5-5,8-5,8, 8+5+5 = -2 ,3,8,13,18

Part b:A geometric sequence with a fifth term of 1/3 and constant ratio of 1/3.

TO find the first five terms, since the constant ratio of 1/3, so we multiply 1/3 to third term to get fourth term, and multiply fourth term by 1/3 to get fifth term .

And to get the first two terms, we will divide third term by 1/3, to get the second term and divide the second term by 1/3 to get the first term, that is

3,1,\frac{1}{3}, \frac{1}{9},\frac{1}{27}

Use substitution to solve the system of equations.<br> y + x = 3<br> y = 1.5x + 1
jeyben [28]

Answer:

x=0.8, y=2.2 (0.8, 2.2).

Step-by-step explanation:

y+x=3

y=1.5x+1

-------------

1.5x+1+x=3

2.5x=3-1

2.5x=2

x=2/2.5

x=0.8

y+0.8=3

y=3-0.8

y=2.2
