Answer:

radius=2

Step-by-step explanation:

if the circumference=4pi and the formula is 2pir then r must be 2 and would look like this:

What are the next 4 terms to this sequence<br><br>2, 6, -4, 10, -14,
Kay [80]

Answer:

24, -38, 62, -100

Step-by-step explanation:

The recursive formula is   a_n = a_(n-2)  -  a_(n-1)

so. we try this 4 times after the -14 term

a_3 = -4 =  2 - 6 =   a_1 - a_2

...

a_6  = a_4 - a_5 = 10 - (-14) = 24

a_7 = a_5 - a_6 = -14 - (24) = -38

a_8 = a_6 - a_7 = 24 - (-38)  = 62

a_9 = a_7 - a_8 =  -38 - 62 = -100

a_10 = a_8 - a_9 = 62 - (-100) = 162

calculate the side lengths a and b to two decimal places angle a is 64 angle b is 85 and line ab is 9.3? PLEASE HELP ASAP
qaws [65]
∠C = 180° - (∠A + ∠B) = 180° - (64° + 85°) = 180° - 149° = 31°
AC= \frac{9.3*sin(85)}{sin(31)} = \frac{9.3*0.9962}{0.515} =17,99 \\  \\ BC=\frac{9.3*sin(64)}{sin(31)} = \frac{9.3*0.8988}{0.515} =16,2

For the diagram below, form an equation and then solve it to calculate the value of x
Talja [164]
You apply the sum of interior angles formula ie. (n-2)180. n=number of sides
since a pentagon has 5 sides it will be (5-2)180=540.
now add everything. x-5+x-6+2x-7+x+2x-2=540.
Solve for x: 7x-20=540
7x=540+20
7x=560
x=560/7
x=80
