Answer: Our third term is 4m.

Step-by-step explanation:

Since we have given that

a_1=m\\\\a_n=2a_{n-1}

We need to find the third term i.e. a_3

According to general recursive terms:

a_3=2a_2

So, we first find the second term:

a_2=2a_1\\\\a_2=2m

so, our third term becomes,

a_3=2a_2\\\\a_3=2\times 2m\\\\a_3=4m

Hence, our third term is 4m.

2(x+16)= 6x please help me :)
jeka94

Let solve:

  2(x+16) = 6x\\2x + 32 = 6x\\32 = 4x\\4x = 32\\x = 8

Thus <u>x = 8</u>

<u></u>

Hope that helps!

Which of the following statements is true
Tresset [83]
Hello There!

The first statement is incorrect as congruent angles have the same measure but it doesn't have to 45°. It can be any value.
The second one is also incorrect. Congruent angles have the same measure but don't always total to 180° (which is what supplementary means). It would only be true if they are congruent right angles.
The third one is also incorrect as they don't always total to 90° either (Which is what complementary means). 
The fourth one is correct, this is because congruent angles are simply angles with the same measure.

In short, you're answer is 4. Congruent angles always have the same measure. 


Hope This Helps You!
Good Luck :)

Answer:

  a) P(t) = 6.29e^(0.0241t)

  b) P(6) ≈ 7.3 million

  c) 10 years

  d) 28.8 years

Step-by-step explanation:

a) You have written the equation.

  P(t) = 6.29·e^(0.0241·t)

__

b) 2018 is 6 years after 2012.

  P(6) = 6.29·e^(0.0241·6) ≈ 7.2686 ≈ 7.3 . . . million

__

c) We want t for ...

  8 = 6.29·e^(0.0241t)

  ln(8/6.29) = 0.0241t

  t = ln(8/6.29)/0.0241 ≈ 9.978 ≈ 10.0 . . . years

__

d) Along the same lines as the calculation in part (c), doubling time is ...

  t = ln(2)/0.0241 ≈ 28.7613 ≈ 28.8 . . . years
