Can You Please Explain How To Do Problem #10? Thank you! :)

Answer:

separate and square both the top and bottom

the square of square root three is just 3 and the square of 3 (the bottom of the fraction) is 9

so now you have 3(i^2) /9

you can simplify this by three and then i^2 is -1

you now have -1/3 and thats the final answer

The function L = 0.8T^2 models the relationship between L, the length in feet of a pendulum, and T, the period in seconds of the

Semmy [17]

The correct option is "d".
Given that L = 0.8T²
length of pendulum = 30ft

L= 0.8T²
30 = 0.8T²
T² = 30 / 0.8
T² = 37.5
T = √37.5 = 6.1 seconds
<span>So, 6.1 is the closest to the period in seconds for a pendulum that is 30 ft long.</span>

Please help! Given the function problem

dedylja [7]

Answer:

Step-by-step explanation:

So we have the function:

$f(x)=\frac{9}{5}x+32$

To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:

$x=\frac{9}{5}f^{-1}(x)+32$

Subtract 32 from both sides:

$x-32=\frac{9}{5}f^{-1}(x)$

Multiply both sides by 5/9. The right side will cancel. Thus:

$f^{-1}(x)=\frac{5}{9}(x-32)$

Our answer is B.

And we're done!

How many revolutions does a go kart with a wheel circumference of 62.8318 inches make in a 1609 m race? Please answer as quickly

Rudiy27

Answer: 1008 revolutions

Step-by-step explanation:

1 revolution is equal to $2\pi r$

To find how many revolutions the wheel makes, you must divide the distance traveled in the race between the circumference of the wheel

You must first convert 62.8318 in to meters.

We know that 1 inch is 0.0254 meters

Then

$62.8318\ in*\frac{0.0254\ m}{1\ in}= 1.5959\ m$

$revolutions = \frac{1609}{1.5959}\\\\revolutions=1008.21\\$

Finally The wheel made 1008.21 revolutions
