Answer:6
Step-by-step explanation: All you have to do is divide 3 by 18
Answer: 14
Step-by-step explanation:
The range is the difference between the largest and smallest of the set.
158cm, 159cm, 164cm, 164cm, 167cm, 172cm is the list in smallest to greatest
Take the smallest number, 158cm, and subtracted it from the largest, 172cm, and you get the range.
Answer:
Exponential decay function; -0.94%
Step-by-step explanation:
We are given an exponential function and we are supposed to find whether the given function increases or decreases and also the percentage of increase or decrease.
Th given function is f(x) = 2060
Here x denotes the number of years.
At the start the value was 2060. In the next year it was multiplied by 0.9906.
This means that the value becomes 0.9906 times after each year.
Hence the value decreases by 0.0094 times its original value.
Converting to percentage it becomes 0.94% decrease after each year.
<h2><u>EQUATIONS</u></h2>
We'll solve this equation:
<h3>5x + 17 = 4(3x - 1)</h3>
First, let's apply the distributive property:
5x + 17 = 4(3x - 1)
5x + 17 = 12x - 4
Now, add 4 to both sides of the equation:
5x + 17 = 12x - 4
5x + 17 + 4 = 12x - 4 + 4
5x + 21 = 12x
Substract 5x from both sides:
5x + 21 = 12x
5x - 5x + 21 = 12x - 5x
21 = 12x - 5x
21 = 7x
Now, divide both sides by 7
21 ÷ 7 = 7x ÷ 7
<h3> 3 = x</h3>
Therefore, x = 3.
<h3>B. The equation has one solution.</h3>
The answer is D. If you make a right triangle with the line, then you can use the Pythagorean theorem (a^2+b^2=c^2) to solve for VW. The vertical line would be 4 units and horizontal line would be 2 units. Therefore 4^2+2^2=20 take the square root of 20 and that is the answer.
