Answer:

Step-by-step explanation:

Given is a picture of circle with angle

BOC =7x-11

Also angle of arc BC = angle BOC = 3x+53

Since both are the same equate the two

$7x-11=3x+534x=64x=16$

Now substitute this x value in any one of 3x+53 or 7x-11

Angle COB = angle BOC = 3x+53

= 48+53 = 101 degrees

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

To find length of arc

Central angle = 101

Hence arc lengh = $\frac{101}{360} 2(\pi r)\\=2\frac{101}{360}(3.14)(5)\\=8.81$

Answer:

The first 5 terms are;

-2, 2, 13,38 and 91

Step-by-step explanation:

Here, we want to write the first 5 terms of the sequence.

We already have the first term as 1

Now, we need the 2nd term

Putting two in place of n, we have ;

2f(1) + 3n

= 2(-2) + 3(2) = -4 + 6 = 2

For the 3rd term, put 3 in place of n

2f(2) + 3(3)

sine f(2) = 2, we have

2(2) + 9 = 4+ 9 = 13

For the fourth term, put 4 in place of n, we have

2f(3) + 3(4)

since f(3) = 13

we have; 2(13) + 12 = 26 + 12 = 38

For the 5th term, put 5 in place of n, we have

2f(4) + 3(5)

since f(4) = 38, we have

2(38) + 15 = 76 + 15 = 91

What fraction strips could you make if you started with a fourths strip?

Tju [1.3M]

Anything that with a denominator that is a multiple of 4, for example: $\frac{2}{8}$ , $\frac{3}{12}$ , $\frac{4}{16}$ , $\frac{5}{20}$ , and so on.

Hope this helps you =)

4. Which of the following functions has a rate of change that stays the same?

BaLLatris [955]

Answer:

$y=-4x+10$

Step-by-step explanation:

A linear function has a constant rate of change.

So all you need to do is to identify which of the given options is a linear function.

$y=-4x+10$ is a linear function and the rate of change is -4.

We can see this is a constant.

$y=\frac{1}{2}x^2$ has a variable rate of change which is $x$

$y=3^x$ also has a rate of change which is $3^x\ln3$

$y=x^2+2$ also has a variable rate of change which is 2x

Find the product <br><br> 5/6 * 30

olga55 [171]

25

Explanation:

5/6 • 30/1

Because 30 is a whole number one puts it over 1 and since it’s multiplication one multiplies straight across

Leaving:

150/6

And that simplifies to 25

I need some help with this. It has to do with the exterior angle therom but i just dont understand it.

NISA [10]

The exterior angle theorem is that exterior angle of x + 80 = x^2 + 3x.
