3. A bicycle wheel has a diameter of 559 mm and has 32 equally spaced spokes. What is the approximate arc

Write an equation with a slope of -1/2 in each form. point-slope form slope-intercept form.

Evgen [1.6K]

For the case of a line through

(

2

,

7

)

and

(

1

,

−

4

)

we have

slope

m

=

Δ

y

Δ

x

=

−

1

−

2

=

−

1

=

Using the point

(

2

,

7

)

we can write the equation of the line in point slope form as:

y

−

7

=

m

(

x

−

2

)

where the slope

m

=

11

.

That is:

y

−

7

=

11

(

x

−

2

)

To get point intercept form, first expand the right hand side so...

y

−

7

=

11

x

−

(

11

⋅

2

)

=

11

x

−

22

Then add

7

to both sides to get:

y

=

11

x

−

15

=

11

x

+

(

−

15

)

This is point intercept (

y

=

m

x

+

c

) form with slope

m

=

11

and intercept

c

=

−

15

.

I need help on c and d please

Dennis_Churaev [7]

A

We can't really do this without seeing 28, but I can give you an educated guess. The best way for me to proceed is to solve c.

The conjecture is that x = a + b. You should always find that to be true. C is the clincher.

Here's how you do that.

x + c = 180o That's true because all straight lines have 180o. If two angles make up the straight line that means that they are always equal to 180o So x + c = 180o

Now we move to the next step. All triangles also have 180o. That means that a + b + c = 180o

So we have two conditions that equal 180o. Equalities can be equated to one another.

a + b + c = x + c Subtract c from both sides.

a + b = x.

Study what has happened. Put in mathese, the two remote interior angles equal the exterior angle, which is what you are trying to prove.

Summary

a cannot be solved without 28

b you should say that the two remote angles (a and b) will always total x

c The proof is provided for you.

A veterinarian has 70 clients who own cats, dogs, or both. Of these clients, 36 own cats, including 20 clients who own both cats

MrRa [10]

Answer:

The three statements are true.

Step-by-step explanation:

The question is incomplete:

A veterinarian has 70 clients who own cats, dogs, or both. Of these clients, 36 own cats, including 20 clients who own both cats and dogs. Which of the following statements must be true? Indicate all such statements.

A. There are 54 clients who own dogs.

B. There are 34 clients who own dogs but not cats.

C. There are 16 clients who own cats but not dogs.

A. There are 54 clients who own dogs.

TRUE. Of the 70 clients, only 36 own cats. There are left 34 clients that own only dogs. If we add the 20 clients that own both cats and dogs, we have 34+20=54 clients who own dogs.

B. There are 34 clients who own dogs but not cats.

TRUE. Of the 70 clients, only 36 own cats. Then, there are left 70-36=34 clients that own only dogs.

C. There are 16 clients who own cats but not dogs.

TRUE. Out of the 36 clients that own cats (only of with dogs), there are 20 that own both. Therefore, there are 36-20=16 clients that own only cats.
