Answer:

The number given in standard notation is 0.0000805

Step-by-step explanation:

When you work with very large or very small numbers, you use scientific notation for numbers those quantities. Scientific notation is based on the idea that it is easier to read an exponent than to count many zeros in a number.

In scientific notation a number (between 1 and 10) is multiplied by a power (positive or negative) of base 10. The power to which the base is raised represents the number of times the comma moves. It is always an integer, positive if it moves to the left, or negative if the comma moves to the right.

To write this number in decimal notation, you convert the power of 10 into a series of zeros between the number and the decimal point. Since the exponent is negative, all those zeros go to the left of the number 8. For each power of 10, move the decimal point one place to the right. You should keep in mind that the number of zeros after the decimal point will always be 1 less than the exponent.

Taking into account everything previously said <u><em>the number given in standard notation is 0.0000805 </em></u>

The equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t

<h3>Equation</h3>

There are three basic types of equation in mathematics. Namely:

  • Linear equations
  • Quadratic equations
  • Simultaneous equations

  • Monthly fee = $50
  • One-time joining fee = $150
  • Total cost = C
  • Number of months = t

C = 150 + 50t

Therefore, the equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth.
Keith_Richards [23]

Answer:

8.0 seconds to the nearest tenth,

Step-by-step explanation:

h=-16t^2 +vt + c.

-16t^2 + 116t + 101 = 0

t =  [ -116 + /- √(116^2 - 4*-16*101) ] / (-32)

t = (-116 +/- √19920) / (-32)

t = -0.79, 8.036  (we ignore the negative root)

The time in flight = 8.036 seconds.

In the isosceles trapezoid below,<br> X =<br> 5x+ 15°<br> 7x-11°
tangare [24]

Answer:

x = 13°

Step-by-step explanation:

5x+15°=7x-11°

5x-7x = -11°-15°

-2x = -26° divide both sides by -2

x = 13°

5x+15° = 5×13°+15° = 80°

7x-11° = 7×13° -11°. = 80°

Answer:

\frac{16}{81}

Step-by-step explanation:

Just Square the numbers like a normal equation.

4² = 16

9² = 81

This gives us \frac{16}{81}
