Here is the equation of a circle in standard form.

Mathematics

Masteriza [31]3 years ago

Answer:

C

Step-by-step explanation:

The equation is in the standard form for a circle:

(x-h)^2+(y-k)^2=r^2

where (h,k) is the center, and r is the radius

If we compare the 2 equations:

(x-h)^2+(y-k)^2=r^2

(x + 10)2 + (y + 9)2 = 100

We can see that r^2 is equal to 100. Let's set them equal to each other.

r^2=100

Since r is being squared, take the square root of both sides. This will cancel out the exponent.

\sqrt{r^2}=\sqrt{100}

r=10

So, our radius is 10, or choice C

3. What % of 100 is 13?
Sedbober [7]

Answer:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 13 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 13 is 100%, so we can write it down as 13=100%.

4. We know, that x is 100% of the output value, so we can write it down as x=100%.

5. Now we have two simple equations:

1) 13=100%

2) x=100%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

13/x=100%/100%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 100% of 13

13/x=100/100

(13/x)*x=(100/100)*x       - we multiply both sides of the equation by x

13=1*x       - we divide both sides of the equation by (1) to get x

13/1=x

13=x

x=13

now we have:

100% of 13=13

Using this formula, what is the acceleration of an object with F = 7.92 newtons and m = 3.6 kilograms? Express your answer to th
g100num [7]

We have to use the following formula which is

F = m * a

Given values of F and m are 7.92 Newtons and 3.6 kilograms .

Substituting these values in the formula, we will get

7.92 = 3.6 a

To solve for a, we have to divide both sides by 3.6 that is

a = \frac{7.92}{3.6}=2.2

And that's the required answer .
