Step-by-step explanation:

  • v = speed of the wind

5(550 + v) = 6(550 - v)

2.750 + 5v = 3.330 - 6v

5v + 6v = 3.300 - 2.750

11v = 550

v = 550 ÷ 11

v = 50mph

Step-by-step explanation:

let v is the speed of the wind,

the equation of the speed:

(550 + v ) × 5 = (550 - v) × 6

2750 +5v = 3300 - 6v

11v = 3300 - 2750

11v = 550

v = 550/11

v = 50

therefore, the speed of the wind =

50 mph

Apply the laws of exponents, calculate the result and express the result in scientific notation, and as a decimal: (8.1*10^-4)^2
AfilCa [17]
<h3>Answer:</h3>
  • the result in scientific notation is 6.561×10⁻⁷
  • the result as a decimal is 0.000 000 656 1
<h3>Explanation:</h3>

The rules of exponents say the exponent outside parentheses applies to each factor inside parentheses.

... (8.1*10^-4)^2 = 8.1^2 × (10^-4)^2

... = 65.61 × 10^-8

... = 6.561 × 10^-7 . . . . adjust to scientific notation with one digit left of the decimal point

The exponent of -7 means the decimal point in the decimal number is 7 places to the left of where it is in scientific notation. That is ...

... 6.561 × 10^-7 = 0.0000006561

For this case we have the following function:
 f (x) = (1/3) * (4 ^ x)
 We must evaluate the function for x = 2
 We have then:
 f (2) = (1/3) * (4 ^ 2)
 Rewriting:
 f (2) = (1/3) * (16)
 f (2) = 16/3
 Answer:
 
The function evaluated at x = 2 is:
 
f (2) = 16/3
