The percentage of 0 - 17 in 2015 is 23.97% and the percentage is decreasing by 0.048% in 2015
The percentage of 0 - 17 in 2015The equation of the function is given as
P(x) = 26x^-0.03
In 2015, x = 15
Substitute x = 15 in the equation P(x) = 26x^-0.03
P(15) = 26 * 15^-0.03
Evaluate the expression
P(15) = 23.97
Hence, the percentage of 0 - 17 in 2015 is 23.97%
How fast is the percentage decreasing in 2015The equation of the function is given as
P(x) = 26x^-0.03
Differentiate the function
P'(x) = -0.03 * 26x^-1.03
In 2015, x = 15
Substitute x = 15 in the equation
P'(15) = -0.03 * 26 * 15^-1.03
Evaluate
P'(15) = -0.048
Hence, the percentage is decreasing by 0.048% in 2015

Interval Notation
Interval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers. For example, the set of numbers x satisfying 0 ≤ x ≤ 5 is an interval that contains 0, 5, and all numbers between 0 and 5.
Different Types Of Intervals
Intervals can be classified based on the numbers the set comprises. Some sets include the endpoints specified in the notation, while some might partially or not include the endpoints. In general, there are three types of intervals given as,
Open Interval
Closed Interval
Half-Open Interval
Let us understand the interval notation and different types of intervals in detail using solved examples.
Interval Notation:
y = |x4|

In the figure below, parallelogram ABCD was
translated to parallelogram A'B'C'D'.
How many units and in which direction were
the x-coordinates of parallelogram ABCD
moved?
A. Left 3
B. Right 3
C. Left 7
D. Right 7
Answer:
C. Left 7
Step-by-step explanation:
The question asks us about the number of units the x-coordinates of the parallelogram moved, therefore we have to look for the horizontal translation of the points A, B, C, and D.
To do this, we can look at the position of any of these points and the position of its corresponding point, to figure out how many units to the left or right they have moved.
For example, let's look at A and A':
To go from A to A', we have to move 7 units to the left.
It's the same for B and B' as well as the other points and their corresponding points.
Therefore the x-coordinates of parallelogram ABCD have moved 7 units to the left.

What is a ratio?A ratio can be defined as a mathematical expression that's used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.
What is a proportion?A proportion can be defined as an expression which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.
Next, we would determine the ratio of the energy released by elements A and B:
EB : EA = EB/EA
Ratio = 1.3 × 10¹⁰/5.1 × 10⁸
Ratio = 25.49 ≈ 26.0

-2/3(1.5÷0.25÷5/4)-5/6
The value of the given expression is -121/ 30.
PEMDAS stands for parentheses, exponents, multiplication, division, addition, then subtraction. It is basically the rule of the order in which a mathematical expression must be solved.
Here, we are given an expression- -2/3 (1.5 ÷ 0.25 ÷ 5/4) -5/6
It can be written as -2/3 (15/10 ÷ 25/ 100 ÷ 5/4) -5/6
= -2/3 (3/2 ÷ 1/4 ÷ 5/4) -5/6
As per the rules of PEMDAS, we first deal with the terms inside the bracket-
(3/2 ÷ 1/4 ÷ 5/4) = (3/2 × 4 × 4/5)
= (3 × 2 × 4/5)
= 24/5
Thus, the expression becomes-
-2/3 (24/5) -5/6
= -48/ 15 - 5/6
LCM of 15 and 6 is 60
⇒ -(48 × 4)/ 60 - (5 × 10)/ 60
-192/ 60 - 50/ 60
= (-192 - 50)/ 60
= -242/ 60
= -121/ 30
Thus, the value of the given expression is -121/ 30.

f(x)=4x^2-x-3, find x when f(x)= -3
Answer:
x = 0 or x = 1/4
Step-by-step explanation:
f(x) = 4x^2-x-3 = -3
4x^2 - x - 3 = -3
4x^2 - x = 0
x(4x - 1) = 0
x = 0 or 4x - 1 = 0
x = 0 or x = 1/4
Answer:
The values for x are x =0 x = 1/4
Step-by-step explanation:
f(x)=4x^2-x-3
find f(x) = -3
Let f(x) = -3
Solve for x
-3 = 4x^2-x-3
Add 3 to each side
-3+3 = 4x^2-x-3+3
0 = 4x^2-x
Factor out an x
0 = x( 4x-1)
Using the zero product property
0 = x 4x-1 =0
0=x 4x=1
0=x x = 1/4
The values for x are x =0 x = 1/4
b. A lap pool has a length of 27 yards, a width of 23 yards, and a depth of 5 yards. Find the pool's surface area (the water surface) and the total volume of water that the pool holds.
The volume is 3105 and the surface area is 1742
What is the volume of and what is the surface area?The given parameters are
Length = 27 yards
Width = 23 yards
Height = 5 yards
The volume is
Volume = Length * width * height
So, we have
Volume = 27 * 23 * 5
Evaluate
Volume = 3105
The surface area is
A =2 *(LW + LH + WHW)
So, we have
A = 2 * (27 * 23 + 27 * 5 + 23 * 5)
Evaluate
A = 1742
Hence, the volume is 3105 and the surface area is 1742

What is the correct graph for:
equation: y= x^2 - 1
Answer:
The first graph.
Hope this helps :)
Step-by-step explanation:
The y-intercept in the equation y = x^2 - 1 is -1.
So the first graph represents the point where the line intercepts the y-axis which is at - 1.
The y-intercept for the second graph is not - 1.
So the first graph would be correct for the equation

Which inequality correctly compares 5/6,1/2,3/9
and 1?
The inequality between (5/6), (1/2), (3/9) and 1 can be best described by
[tex][\frac{3}{9} < \frac{1}{2} < \frac{5}{6} < 1][/tex].
As per the question statement, we are provided with three proper fractions, (5/6), (1/2), (3/9) and an integer, 1.
We are required to correctly compare the inequality between the question mentioned terms.
Since all three fractions are proper fractions, i.e., their numerators are less than their denominators, hence, all three fractions are less than the integer 1.
Thus, we are required to determine the order of magnitude between the fractions. To do so, we will calculate the L.C.M of the denominators.
L.C.M of 2, 6 and 9 is 18.
Therefore, we will multiply both the numerator and denominators of (5/6) with 3, and we will obtain [tex]\frac{5*3}{6*3} =\frac{15}{18}[/tex].
Similarly, we will multiply both the numerator and denominators of (1/2) with 9, and we will obtain [tex]\frac{1*9}{2*} =\frac{9}{18}[/tex].
Finally, we will multiply both the numerator and denominators of (3/9) with 2, and we will obtain [tex]\frac{3*2}{9*2} =\frac{6}{18}[/tex].
Now comparing [tex][\frac{15}{18}, \frac{9}{18}, \frac{6}{18}],[/tex] we can see than all the denominators are now same (18). Hence, the order of magnitude of the fractions can be determined in the order of magnitude of the numerator values, i.e.,
[15 > 9 > 6] or, [6 < 9 < 15].
Therefore, [tex][\frac{6}{18} < \frac{9}{18} < \frac{15}{18}][/tex], or, [tex][\frac{3}{9} < \frac{1}{2} < \frac{5}{6}][/tex].
And since 1 is greater than any proper fraction, The inequality between (5/6), (1/2), (3/9) and 1 can be best described by [tex][\frac{3}{9} < \frac{1}{2} < \frac{5}{6} < 1][/tex].

Which of the dot plots shows a symmetric distribution?
The dot plot that has a symmetric distribution is option b.
What is a dot plot?A dot plot is a graph that has similarities with a histogram. A dot plot is made up of a number line and dots. A dot plot is used to represent the frequency of a data set.
The dots in the dot plot represent the frequency of the data. The greater the frequency of a data, the greater the number of dots the number has. For example, if a number has a frequency of 6, it would have 6 dots have it.
A dot plot is symmetric if the left side of the graph and the right side of the graph are mirror images of each other. A dot plot is skewed to the left if there are more dots on the left side of the graph. A dot plot is skewed to the right if there are more dots on the right side of the graph.
