EACH central angle = 360 / number of sides
number of sides = 360 / each central angle
number of sides = 360 / 40
number of sides = 9
Answer:
<em>0.15</em>
Step-by-step explanation:
Given the expression that relates the distance and the time with the expression:
d = 0.15t
d is the distance
t is the time
To determine how fast it is flying (Speed), we will need to use the formula
Speed = distance/time
s = d/t
From the given equation we can se that 0.15 = d/t
Comparing this to the general equation, we will see that s = 0.15
<em>Hence the airplane is flying at 0.15</em>
Answer:
See below
Step-by-step explanation:
This will create a cylinder volume = 1/2 pi r^2 h = 1/2 pi 4 * 12
= 24 pi = 75.398 in^3
Answer:
$20-$12=
Step-by-step explanation:
20-12=8
<span>f(x) = x</span>² <span>+ 12x + 6 </span>→ y = x² + 12x + 6<span>
Let us convert the standard form into vertex form.
1) Complete the squares. Isolate x</span>² and x terms.
<span>y - 6 = x</span>² + 12x
<span>
2) Create the perfect square trinomial. Whatever number is added on one side must also be added on the other side.
y - 6 + 36 = x</span>² + 12x + 36<span>
y + 30 = (x + 6)</span>²
<span>y = (x + 6)</span>² - 30 ← Vertex form
<span>
To check:
y = (x + 6) (x + 6) - 30
y = x</span>² + 6x + 6x + 36 - 30
<span>y = x</span>² + 12x + 6<span>
The zero that could be added to the given function is 36, -36</span>
