CAN SOMEONE PLEASE HELP ME WITH THIS QUESTION???

tangare [24]

Answer:

The complete answer is explained below.

Step-by-step explanation:

The problem is demanding to simply determine the number of years each color light would last.

We know the following information from the question:

As it is clear that a red light remains TURNED ON 50% of the time.
Green remains TURNED ON 42% of the time
Yellow remains TURNED ON 8% of the time.

Also the bulbs for each color are LED and are designed to last 100,000 hours. So, each light does last 100,000 hours.

lets make conversions

$1\:day\:=\:24\:hours$

$1\:year\:=\:365\:days$

Dividing $100,000$ hours by $24$ hours would bring $4166.67$ days

Dividing $4166.67$ days by $365$ days would bring $11.4$ years, meaning 11 years and 4 months.

Keywords: light, conversion, day, hours

3 (Picture) CONVERGENT AND DIVERGENT SERIES PLEASE HELP!!

scoundrel [369]

Answer:

Option C

Step-by-step explanation:

The sum of finite geometric sequence states the following:

$s_{n} =$ Σ $a_{i} r^{i-1} = a_{1}(\frac{1-r^{n} }{1-r} )$

In this case, $r = \frac{900}{1500} = \frac{9}{15} = \frac{3}{5}$ , and $i = 10$

Therefore,

$1500( 1 + \frac{3}{5} + (\frac{3}{5})^{3} + (\frac{3}{5})^{4} + (\frac{3}{5})^{5} + (\frac{3}{5})^{6} + (\frac{3}{5})^{7} + (\frac{3}{5})^{8} + (\frac{3}{5})^{9}) = 1500( 2,4848) = 3.727, 3251$ ≈ $3.727$

Therefore, the correct answer is the option C

0=8x^2+8x-21 in (x-p)^2=q form

Makovka662 [10]

Step-by-step explanation:

8x² + 8x - 21 = 0

8(x² + x) - 21 = 0

8(x + 0.5)² - 23 = 0

8(x + 0.5)² = 23

(x + 0.5)² = 23/8.

Find the perimeter of the figure if the following is true:

sergejj [24]

The perimeter of a figure is the distance around the outside of the figure. To find the perimeter of this figure, we need to add the lengths of all sides. This is:

P = A + B + C + D

P = x² + 4x + 8 + 2x² + x

P = 3x² + 5x + 8

The perimeter is 3x² + 5x + 8.
