A painter has a 24 foot ladder that he is using to paint a house. For safety reasons, the ladder must be placed at least 8 feet
Lana71 [14]

Answer:

The ladder can reach a height of 22.6 feet.  

Step-by-step explanation:

In order to find the height that the ladder can reach, you need to use the Pythagorean Theorem.  The Pythagorean Theorem assumes that the house to the ground will form a right triangle and the leaning ladder is the hypotenuse.  Using the formula:  a² + b² = c², we can plug in the values that we know and solve for the missing variable.  In this case we know the base of the triangle 'b' and the hypotenuse 'c':  a² + 8² = 24² or a² + 64 = 576.  To solve for a, we must first subtract 64 from both sides:  a² + 64 - 64 = 576 - 64 or a² = 512.  In order to find just the value of 'a', which represents the height, we need to take the square root of both sides:  √a² = √512 or a ≈ 22.6 feet.

Which number is equal to 10 Superscript negative 3? –1,000 –30 0.001 0.003
Karolina [17]

<u>Given</u>:

The given expression is 10^{-3}

We need to determine the equivalent number.

<u>Equivalent expression:</u>

To determine the equivalent number, let us solve the expression 10^{-3}

Thus, let us apply the exponent rule a^{-b}=\frac{1}{a^{b}} , we get;

10^{-3}=\frac{1}{10^{3}}

Also, the term 10³ can be written as 10^{3}=1000

Thus, we get;

\frac{1}{1000}

Dividing, we get;

0.001

Hence, the equivalent number is 0.001

Hence, Option c is the correct answer.
