Charlize wants to measure the depth of an empty well. She drops a ball from a height of 3 feet into the well

Mathematics
1 answer:
pentagon [3]3 years ago
5 0

Answer:

  about 151 feet

Step-by-step explanation:

The height of the ball at a time of 3.1 seconds is given by Charlize's equation as ...

  h(3.1) = -16(3.1)^2 +3 = -150.76 . . . feet

The well is about 151 feet deep.

_____

<em>Comment on this measurement</em>

The speed of sound is sufficiently slow that it will make a difference in the time Charlize records. She would get a more accurate measurement if she were able to <em>see</em> the ball hit bottom.

If f(x)=16x- 30 and g(x)= 14x-6, for which value of x does (f-g)(x)=0?
Georgia [21]

Answer:

x=12

Step-by-step explanation:

16x-30-(14x-6)=2x-24=0. add 24 on both sides to get 2x=24. divide by 2 on both sides to get x=12

What is the Inverse Equation<br><br>f(x) =6x-1 ?? please I need help!​
Scrat [10]

Answer:

f^{-1}(x)=\frac{x+1}{6}

Step-by-step explanation:

So we have the function:

f(x)=6x-1

To find the inverse function, switch x and f(x), change f(x) to f⁻¹(x), and solve for f⁻¹(x). Therefore:

f(x)=6x-1

Switch:

x=6f^{-1}(x)-1

Add 1 to both sides:

x+1=6f^{-1}(x)

Divide both sides by 6:

f^{-1}(x)=\frac{x+1}{6}

And that's our answer :)

You score 64/75 on your first test. After your second test, your teacher tells you your test average is 88%
gregori [183]

First you need to divide 64 by 75 and then multiply by 100 which is 85.3% which then you need to find the average of the 2 which will be (85.3+x)/2=88 where x= the value of the second test.

Then you will need to isolate the x with the following steps:

  1. multiply each side by 2 making it 85.3+x=176
  2. Subtract 85.3 from each side
  3. this results in 90.7
