What is the best approximation for the perimeter of a semicircle with a diameter of 12 cm?
maw [93]
When we speak of the word "perimeter" of a circle, we mean to say the circumference. Since we are only given a semicircle, the perimeter would be,
                                      perimeter = (pi)(radius) + diameter
Substituting the known values,
                                      perimeter = (3.14)(6 cm) + 12 cm
The value of the perimeter is,
                                      perimeter = 30.84 cm

Her final score should be 21. You can add both 3 1/2 and 3 1/2 which will give you 7. Then substract it from 28.

Which is the graph of the following equation?
lesantik [10]

Given equation is

\frac{(x-5)^2}{16} - \frac{(y-2)^2}{9}=1

The given equation is in the form of

\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2}=1

a^2= 16  , so a=4

b^2 = 9 so b= 4

The value of 'a' is greater than the value of 'b'

So it is a Horizontal hyperbola

First two graphs are horizontal hyperbola

Here center is (h,k)  

h= 5 and k =2 from the given equation

So center is (5,2)

Now we find vertices

Vertices are (h+a,k)  and (h-a,k)

We know h=5, k=2  and a=4

So vertices are (9,2)  and (1,2)

Second graph having same vertices and center

The correct graph is attached below

Simplify the expression. Write your answer as a complex number.
prohojiy [21]

Answer:

15-8i

Step-by-step explanation:

we know that

The algebraic expression is equal to

5\sqrt{9}-\sqrt{-64}}

Remember that

\sqrt{9}=3

and

i=\sqrt{-1}

so

\sqrt{-64}=i\sqrt{64}=8i

substitute

5\sqrt{9}-\sqrt{-64}}=5(3)-(8i)=15-8i
