Answer:
The length of segment XY can be found by solving for a in
The measure of the central angle 
is 
.
Step-by-step explanation:
If the regular octagon has a perimeter of 122.4cm, then each side is 
The measure of each central angle is 
The angle between the apothem and the radius is 
The segment XY=a is the height of the right isosceles triangle.
We can use the Pythagoras Theorem with right triangle XYZ to get:
Therefore, the correct options are:
The length of segment XY can be found by solving for a in
The measure of the central angle is .
Answer:
100n+50
Step-by-step explanation:
the dentist charges $100 dollars per cavity found. Per indicates multiplication. Since there is an additional fee, we add $50 to the $100n, which will make the expression
<em>$</em><em>100n</em><em>+</em><em>5</em><em>0</em>
Answer:
A).
Step-by-step explanation:
The 72 is the initial height in feet of the object.
Initially the time = 0 seconds. If we plug zero into the function we get:
h(0) -16(0)^2 + 110(0) + 72
= 0 + 0 + 72
= 72 feet.
Answer:
x=2.17
Step-by-step explanation:
14.88+x=17.05
We move all terms to the left:
14.88+x-(17.05)=0
We add all the numbers together, and all the variables
x-2.17=0
We move all terms containing x to the left, all other terms to the right
x=2.17
