13.542 = 35.42*0.1 +10
13.542 is 10 more than 10% of 35.42
781 = 78.1 * 10
781 is equal to 10 times 78.1
1.2 has two significant figure but 01.20 has 3 significant figure
<h3>
Answer: B) 569 feet</h3>
========================================================
Work Shown:
sin(angle) = opposite/hypotenuse
sin(6) = a/5440
5440*sin(6) = a
a = 5440*sin(6)
a = 568.634840176034
a = 569 feet, which shows why <u>choice B</u> is the answer.
This value is approximate. Make sure your calculator is in degree mode. One way to check is to compute sin(30) and you should get 0.5
side note: 569 feet is roughly equal to 0.1078 miles.
the answer is The domain is all real numbers, and the range is all real numbers greater than or equal to –4.
To solve this problem you must apply the proccedure shown below:
1. You have the following system of equation:
2. As you can see, you can cancel out the variable 
, because it has equal coefficient with different signs at both equations. Then, if you add both equations, you obtain:
3. Let's substitute the value obtained into the second equation to calculate the other variable:
The answer is: (6,-6).
Answer:
k = 9
Step-by-step explanation:
Consider the pattern on the right side , that is
= k(k + 2) + 1 = k² + 2k + 1
Equating
k² + 2k + 1 = 100 ( subtract 100 from both sides )
k² + 2k - 99 = 0 ← in standard form
(k + 11)(k - 9) = 0 ← in factored form
Equate each factor to zero and solve for k
k + 11 = 0 ⇒ k = - 11
k - 9 = 0 ⇒ k = 9
But k > 0 , then k = 9
