Express 4 less than a number is actually easy.
X will be our number.
But it won't be just X, it would be X squared or x^2.
So you do... (x^2)-4.
(The 4 is what you subtract).

The area of the shaded circle below is 78.5 square inches. The area of the large circle is 314 square inches. A shaded circle is

The probability that a point is chosen at random in the shaded region will be 0.25.

<h3>What is probability?</h3>

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

Probability = (Favorable event) / (Total event)

The area of the shaded circle below is 78.5 square inches.

The area of the large circle is 314 square inches.

A shaded circle is inside of a larger unshaded circle.

Then the probability that a point is chosen at random in the shaded region will be

P = 78.5 / 314

P = 1 / 4

P = 0.25

Then the correct option is A.

What is the solution to ln (x2 - 16) = 0?

bogdanovich [222]

ANSWER

$x = \pm \sqrt{17}$
EXPLANATION

The given equation is

$ln( {x}^{2} - 16) = 0$

Take antilogarithm of both sides to base e.

${e}^{ ln( {x}^{2} - 16) } = {e}^{0}$

This will simplify to

${x}^{2} - 16 = 1$

Group like terms to obtain,

${x}^{2} = 1 + 16$

${x}^{2} = 17$

Take square root of both sides to get,

$x = \pm \sqrt{17}$

Paul finished his 800 meter race in 2 minutes and 2 seconds. Jeff finished in 121 seconds. Who finished first? (PLESES SHOW WORK

elixir [45]

Answer:

Jeff finished first

Step-by-step explanation:

To solve this equation, I can either converts 2 minutes 2 seconds to seconds or convert 121 seconds to minutes

<u><em>CONVERT 2 MINUTES 2 SECONDS TO SECONDS</em></u>

60 seconds = 1 minutes

to convert 2 minutes 2 seconds to seconds, multiply 2 minutes by 60 and then add 2 seconds to it

2 x 60 = 120 seconds

120 seconds + 2 seconds = 122 seconds

Paul finished in 122 seconds while Jeff finished in 121 seconds. Jeff finished first

<u><em>CONVERT 121 SECONDS TO MINUTES</em></u>

60 seconds = 1 minutes

To convert 121 seconds to minutes, we have to divide by 60

121/60 = 2 minutes 1 second

Paul finished the race in 2 minutes 2 seconds while eff finished the race in 2 minutes 1 second. Jeff finished first
