Answer:
A) 1 < x < ∞
Step-by-step explanation:
"Increasing" means the graph goes up to the right. This graph is increasing for values of x greater than 1. (x=1 is a minimum. The graph is decreasing toward the minimum on the left of that value, and increasing from the minimum on the right of that value.)

Step-by-step explanation:
First we need to find the length of BC and for that we gonna use Pysagoras theorem
10^2 + (2√11)^2 = |BC|^2
√144 = |BC|^2
12 = BC Now we will use this to find the value of x
x^2 = 12^2 + 9^2
x^2 = 144 + 81
x^2 = 225
√x^2 = √225
x = 15
Answer:
The value of x is 15 cm.
Step-by-step explanation:
There are two triangles in the diagram that share a common side.
The triangles are:
ABC and BDC
First we have to find the third side of BDC so that we can use it to find the value of x.
The triangle is a right angled triangle so Pythagoras theorem can be used to find the third side.
In the triangle
[tex]Base = BD =10cm\\Hypotenuse = BC = ?\\Perpendicular = CD = 2\sqrt{11}cm[/tex]
Pythagoras theorem is given as:
[tex](Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\BC^2 = BD^2 + CD^2\\BC^2 = (10)^2 + (2\sqrt{11})^2\\BC^2 = 100+(2^2 * 11)\\BC^2 = 100+(4*11)\\BC^2 = 100+44\\BC^2 = 144\\\sqrt{BC^2} = \sqrt{144}\\BC = 12cm[/tex]
Now for triangle ABC
[tex]Base = BC = 12 cm\\Perpendicular = AB = 9 cm\\Hypotenuse = AC = x\\[/tex]
Using Pythagoras theorem
[tex]AC^2 = BC^2+AB^2\\x^2 = (12)^2 + (9)^2\\x^2 = 144+81\\x^2 = 225\\\sqrt{x^2} = \sqrt{225}\\x = 15cm[/tex]
Hence,
The value of x is 15 cm.

We can use the fact that in a triangle, the side opposite the smallest angle is the shortest side.
So we need to determine which angle is the smallest.
Now,
In ΔQRS,
m∠Q = 63º, m∠R = 70°, and m∠S= 47°
Now,
m∠S= 47° is the smallest.

QR is the side opposite to m∠S.
Thus,
QR is the shortest side.

The Coefficient of variation is the ratio of the standard deviation and the population mean.
Data Set 1: 2 = 12 and s = = 7
Data Set 2: 2
0.12 and s
= 0.3.
Coefficient of variation = (standard deviation / mean) * 100%
Dataset 1:
Standard deviation = 7 ; mean = 12
Coefficient of variation = (7 / 12 ) * 100% = 0.5833 = 58%
Dataset 2:
Standard deviation = 0.3 ; mean = 0.12
Coefficient of variation = (0.3 / 0.12) * 100% = 2.5 * 100% = 250
Hence dataset 2 varies the most with a greater value of variation Coefficient.

Find x AND the length of each side if ABC is an isosceles triangle with AB = BC . (Answers Rouen to the nearest tenth if needed)
Answers
Answer:
x = 7
AB = 7
BC = 7
Step-by-step explanation:
AB = BC cuz it's an isosceles triangle
In the given isosceles triangle x is 7 units and AB ≅ BC is also of 7 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
As the triangle has two equal sides we can equate two expressions to find x.
∴ 2x - 7 = 4x - 21.
- 2x = - 14.
2x = 14.
x = 7.
AB = 2(7) - 7.
AB = 14 - 7.
AB = 7.
BC will also be of 7 units as AB ≅ BC.

125 is what percent of 50?
Answers
Answer:
250%
Step-by-step explanation:
For this equation we have to use the percent composition formula. It is as follows:
[tex]\frac{part}{whole} *100 = percent[/tex]
Now, we plug in the numbers given in the equation. 125 being the part and 50 being the whole.
[tex]\frac{125}{50} *100 = 250[/tex]
Therefore, 125 is 250% of 50.

The percentage of 125 in whole quantity 50 is, 250%
What is the percentage?Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".
To find what percentage 125 is of 50, we first need to convert the ratio of 125 to 50 into a decimal and then convert the decimal into a percentage.
The ratio of 125 to 50 can be expressed as a fraction: 125/50. We can convert this fraction to a decimal by dividing the numerator by the denominator:
⇒ 125/50
⇒ 2.5
Next, we convert the decimal to a percentage by multiplying it by 100 and adding the percent symbol:
⇒ 2.5 x 100
⇒ 250%
So, 125 is 250% of 50. This means that 125 is equal to 250% of the value of 50.

[tex]-\sqrt{8}[/tex] is roughly equal to -2.8 because 3 * 3 = 9 so that is too much, and 2 * 2 = 4 is too little so it has to be between -2 and -3. Therefore the point is e.

Using the absolute value concept, it is found that the solution is:
[tex]-3 \leq y \leq 21[/tex]Which is given by the second option.---------------------------------
The absolute value of a point, or of a function, measures it's distance to the origin.The inequality given by:
[tex]|y - 9| \leq 12[/tex]
The distance to the origin is of at most 12 between -12 and 12, thus:[tex]-12 \leq y - 9 \leq 12[/tex]
We have to solve both inequalities, and find the intersection.[tex]-12 \leq y - 9[/tex]
[tex]-y \leq 3[/tex]
[tex]y \geq -3[/tex]
[tex]y - 9 \leq 12[/tex]
[tex]y \leq 21[/tex]
The intersection is values of y between -3 and 21(and logical operator, not or), inclusive, thus: [tex]y \geq -3[/tex] and [tex]y \leq 21[/tex], that is: [tex]-3 \leq y \leq 21[/tex]A similar problem, involving absolute value, is given at https://brainly.com/question/24734454

A person runs 1 4/5 miles in 1/5 of an hour determine how many miles they are running per hour
Answers
9/5 * 5/1 = 45/5 = 9 miles
Answer:
Step-by-step explanation: There are different methods to solve this, but I chose to change these into decimals- 1.8 and .20, to make it easier. Since miles per hour is speed, and speed is distance divided by time, all you have to do is fill in the blanks.
Since 1.8 / .20= 9, the answer is 9 miles per hour.
To take it a step farther, you could multiply this by any number of hours, or convert it to minutes. For example, to figure out how far they'd get in 10 minutes, I could divide the unit rate by 60, since there are 60 minutes in an hour, and get 0.15. So, in 10 minutes, they'd get 0.15 miles away.
