Answer:
She is incorrect. The correct answer is 285.74
Step-by-step explanation:
A= (pi)r^2
Training wheel: A= (3.14)(3)^2=28.26in^2
Wheel: A= (3.14)(10)^2= 314in^2
314-28.26=285.74in^2
1. OK, we want csc A, which is 1/sin A. When we have a right triangle whose hypotenuse is the square root of two times the side, we're where the Pythagoreans were twenty five hundred years ago when they realized the diagonal of the unit square was incommensurate with the side.
In other words we have an isoceles right triangle, 45 degree angles,
and
. So
so
fourth choice.
2. AC adjacent to 23, C is a right angle because 23+67=90. We have hypotenuse AB, so
, choice four.
3. The cosine is adjacent over hypotenuse.
The sine is opposite over hypotenuse,
First choice
Answer:
The answer is d.
Step-by-step explanation:
I had this question on a test and saw the actual picture of each graph, the last graph is the only one that has a straight line from the origin to 52:8 which is the easiest way to know if a graph is proportional.
<em>Hope this helps :)</em>

Answer:
option 1
Step-by-step explanation:
formula:(x-h)^(2)*(y-k)^(2)=r^2
well if you move the circle 3 units left h is (-3), plug it in, you get 3, so it is (x+3)^2*(y-k)^(2)=r^2
if you move the circle 2 units up, plug it in you get (-2), so it is
(x+3)^2*(y-2)^(2)=r^2
now, the radius is 3 (we can see from the graph) so radius ^2 is 9, thus
(x+3)^2*(y-2)^(2)=9
this is the answer, and the option that has it is answer is option 1
