What is the explicit rule for the geometric sequence? 4.05, 1.35, 0.45, 0.15, ...

Mathematics
1 answer:
Lelu [443]3 years ago

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

4.05, 1.35, 0.45, 0.15, ...

Since it is a geometric sequence.

So, here, a = 4.05

r = \dfrac{a_2}{a_1}=\dfrac{1.35}{4.05}=0.33

So, we know the formula for nth term in geometric sequence.

a_n=ar^{n-1}\\\\a_n=4.05(0.3)^{n-1}

Hence, First option is correct.

<u>The two angles of the triangle ADB are:</u>

  • m∠A/2 and m∠B/2 or
  • α/2 and β/2

<u>The three interior angles add to 180°, so the missing angle is:</u>

Given f(x) = 3 and g(x) = 5x + 7, find (f + g)(-8).
levacccp [35]

Answer:

-30

Step-by-step explanation:

f(x) = 3 so f(-8) = 3;

g(x) = 5x + 7, so g(-8) = 5(-8) + 7 = -33

Then (f + g)(-8) = 3 - 33 = -30

This is the sum of two functions both evaluated at x = -8.

mestny [16]

Answer:

4

Step-by-step explanation:

B = (6,5)              C = (6,9)

√(x2 - x1)² + (y2 - y1)²

√(6 - 6)² + (9 - 5)²

√(0)² + (4)²

√16

= 4
