Answer:
Step-by-step explanation:
- -1/9 × -5/4: 9 × 4 = 36, -1 × -5 = 5
- Put them together: 5/36
X^2+y^2 = 16
can be written as
(x-0)^2+(y-0)^2 = 4^2
We see that the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2
where
(h,k) = (0,0) is the center
r = 4 is the radius
The polar form of the equation is simply r = 4. Why is this? Because the radius is fixed to be 4 no matter what happens with theta. As theta goes from 0 to 360, the points generated all form a circle centered at (0,0) with radius 4.
Answer: r = 4
Answer:
11
Step-by-step explanation:
divide 209 by 19 to get an equal number of games each month (for 19 months), you will get 11 games each month.
Answer:
Approximately 94% of theaters charge more than $10 to see the movie.
Step-by-step explanation:
Use a calculator with distribution functions such as normalcdf(
Here we have normalcdf(10,1000,11.80, 1.15) = 0.941
Approximately 94% of theaters charge more than $10 to see the movie. This agrees with the last answer choice.
It these triangles are similar, then the sides of the triangles are in proportion:
<em>cross multiply</em>
<em>use distributive property</em>
<em>subtract 10y from both sides</em>
<em>divide both sides by 5</em>
<em>cross multiply</em>
<em>divide both sides by 8</em>
