How do you do 3b+7.1=2.5b+11.5

Answers

3b+7.1=2.5b+11.5

First, you'd take 2.5b and subtract it from 3b

3b-2.5b+7.1=11.5

Simplify:

.5b+7.1=11.5

then, you would take 7.1, and since it is positive, subtract it from 11.5

.5b=11.5-7.1

Simplify:

.5b=4.4

Lastly, you'd take 4.4 and divide it by .5, leaving the unknown factor alone.

b=4.4/.5

Final answer:

b=8.8

What is the complement of 86.4 degrees ?

Answers

Complement for angles means that the total degrees adds up to 90. (these are called complementary angles, supplementary angles add up to 180 degrees!)

Since you already have 86.4, you simple subtract.

90-86.4=3.6

your final answer is 3.6 degrees.

For the following geometric sequence find the recursive formula: {-1, 3, -9, ...}.

Answers

Based on these first few terms, we can deduce that the next term is computed by switching the sign of the previous one, and multiplying it by 3: we start with -1, we switch the sign (1) and multiply by 3 (3); then again we switch the sign (-3) and multiply by 3 (-9), and so on.

Since switching sign is the same as multiplying by -1, we can compute every next term by multiplying the previous one by -3:

$a_1 = -1\na_2 = a_1\cdot(-3) = (-1)\cdot(-3)=3\na_3 =a_2\cdot(-3)=3\cdot(-3)=-9$

So, the recursive formula is

$a_n = -3a_(n-1)$

because it states precisely that the next term is -3 times the previous one.
