Answer:
$29,900
Growth
22%
Step-by-step explanation:
Initial value is when t = 0
v(0) = 29900(1.22)^0
v(0) = 29900(1)
v(0) = 29900
-------------------------
Growth
because 1.22 is greater than 1
----------------------------
Yearly value change
1.22 - 1 = 0.22
0.22 * 100 = 22
22%
Answer: 
Step-by-step explanation:
You need to use the following formula:
Where "r" is the radius and 
is is the central angle of the arc in radians.
Assuming that that the angle 
is the central angle of the arc, and knowing that the radius is 7 centimeters, you can substitute values into the formula.
Therefore, you get:
Answer:
11
Step-by-step explanation:
<h2>You are technically using PEMDAS, since x equals 6 heres what you do. 2 x (6 + 1) -3</h2><h2>Perenthesies first: 6 + 1 =7 now you mulitiply</h2><h2>2 x 7 = 14 so then subtract 14 - 3= 11</h2><h2 />
Answer:
When you see a formula like this, try to operate, so you will see some identities sooner or later. In this case, we have a substraction identity:
\frac{cos ( \alpha - \beta )}{cos \alpha cos \beta } = \frac{cos \alpha cos \beta + sin \alpha sin \beta }{cos \alpha cos \beta } = 1 + tan α · tan β
