x[tex]x^{2}+ 10x =11[/tex]
Answer:
For this problem, x has multiple values, so we will solve for both.
Step-by-step explanation:
[tex]x^2+10x-11=11-11\\x^2+10x-11=0\\[/tex]
Quadratic rule
[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]\mathrm{For\:} a=1,\:b=10,\:c=-11[/tex]
[tex]x_{1,\:2}=\frac{-10\pm \sqrt{10^2-4\cdot \:1\cdot \left(-11\right)}}{2\cdot \:1}[/tex]
Dealing with radicals
[tex]\sqrt{10^2-4\cdot \:1\cdot \left(-11\right)}\\=\sqrt{10^2+4\cdot \:1\cdot \:11}\\=\sqrt{10^2+44}\\=\sqrt{100+44}\\=\sqrt{144}\\=\sqrt{12^2}\\=12\\[/tex]
Multi-solution expression
[tex]x_1=\frac{-10+12}{2\cdot \:1},\:x_2=\frac{-10-12}{2\cdot \:1}[/tex]
Solve for x₁
[tex]\frac{-10+12}{2\cdot \:1}\\=\frac{2}{2\cdot \:1}\\=\frac{2}{2}\\=1[/tex]
Solve for x₂
[tex]\frac{-10-12}{2\cdot \:1}\\=\frac{-22}{2\cdot \:1}\\=\frac{-22}{2}\\= -\frac{22}{2}\\= -11[/tex]
Thus, x has 2 values for 2 different numbers:
x₁ = 1
x₂ = -11

Evaluate the expression.
-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.

Answer:
M would be at (0,-2)
Step-by-step explanation:
The question asks you to rotate the image 180 degrees clockwise. Clockwise means towards the right, such as how a clock moves. Each axis is 90 degrees, so by moving it twice would land at (0,-2).
A horizontal line (such as the x-axis) is 180 degrees, so by mirroring the point, you would see the point is at (0,-2).
At end of the first half of a football game, Nathan had carried the ball for 50.5 yards. By the end of the game, he carried the ball for a total of 75 yards. Find the percent of increase in the number of yards he carried. Round to the nearest whole tenth if necessary
The percent increase in the number of yards is 32.7%
How to calculate the percent increase ?At the end of the football game, Nathan carried the ball for 50.5 yards
At the end of the game, the ball was carried for a total of 75 yards
The percent increase in the number of yards can be calculated dividing the percentage change by the original value and multiplying by 100
= 75 - 50.5/75 × 100
= 24.5/75 × 100
= 0.3266 × 100
= 32.66
= 32.7%
Hence the percent increase in the number of yards is 32.7%

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.

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|
(−∞,∞)

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

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)

Home Depot entered fiscal 2017 with a total capitalization of $21,904 million. In 2017, debt investors received interest income of $877 million. Net income to shareholders was $8,654 million. (Assume a tax rate of 21%.)
Calculate the economic value added assuming its cost of capital is 10%. (Do not round intermediate calculations. Enter your answer in millions rounded to 2 decimal places.)
The economic value added (EVA) for Home Depot in the fiscal year, 2017, is $6,463.60 million.
What is the economic value added?Economic value added (EVA) measures a company's financial performance or economic profit.
EVA is based on the residual wealth of the company for the fiscal year. It measures the value a company generates from its invested funds at the cost of capital.
EVA is calculated by deducting the cost of capital from the operating profit after tax (NOPAT).
Data and Calculations:2017 total capitalization = $21,904 million
2017 interest paid to debt investors = $877 million
Net income to shareholders = $8,654 million
Corporate tax rate = 21%
Profit before taxes = $10,954 million ($8,654/ 1 - 0.21)
Cost of capital = 10%
= $2,190.4 million ($21,904 x 10%)
EVA = NOPAT - (Invested Capital * WACC)
= $8,654 million - $2,190.4 million
= $6,463.60 million.
Thus, the economic value added (EVA) for Home Depot in the fiscal year, 2017, is $6,463.60 million.
