Which values are solutions to the inequality below? Check all that apply.
x² < 144
What are the two answers for this and how do I complete this problem?
9514 1404 393
Answer:
-12 < x < 12
Step-by-step explanation:
It helps to think about what this looks like on a graph.
y = x² describes a parabola that has its vertex at the origin and opens upward. You know that 12² = 144, so the value of x² will exceed 144 when the value of x is more than 12. You also know the parabola is symmetric about the y-axis, so the same will be true for values of x less than -12.
The one solution to the inequality is ...
-12 < x < 12
__
You can also go at this slightly differently--a way you might want to use for more complicated quadratic inequalities. Put the inequality in standard form, and factor it.
x² -144 < 0
(x +12)(x -12) < 0
Note that these factors are zero for x = -12 and for x = 12. The solution is the set of values of x where the sign of the product is negative.
The sign of the product of two numbers will be negative when one of them is negative and the other is positive. Since the zeros of this product are -12 and +12, the sign of the product will be different in the intervals (-∞, -12), (-12, 12), and (12, ∞). In the left-most of these intervals, both factors are negative, so the product is positive and the interval is not part of the solution set.
For the middle of these intervals, (-12, 12), the sign of (x+12) is positive and the sign of (x-12) is negative. The product will have a negative sign, so this interval is part of the solution set.
For the rightmost interval (12, ∞), both factors have positive signs, so the product is positive and the interval is not in the solution set.
Based on the analysis of the signs of the factors, we realize the solution to the inequality is the interval (-12, 12), or -12 < x < 12.
_____
The wording of your question suggests you are given a list of numbers and asked to identify those that satisfy the inequality. We don't see that list, so we can only tell you the set of numbers the solutions must be in.
Note that -12 or +12 are not solutions to this.
Find the range and interquartile range (IQR) of the data set in the box plot.
11,7, 24, 7, 16, 18, 27, 8, 13, 14, 24, 30
Answer:
Range = 23
IQR= 14.5
Step-by-step explanation:
Range is the biggest number- smallest number
so 30-7=23
IQR - Interquartile range = upper quartile - lower quartile
24-9.5=14.5

Eddie is paid $17.25 per hour for a regular 37-hour week. His overtime rate is 1 times his regular hourly
rate. Use his time card above to find his total pay for the week.
Answer:
$638.25
Step-by-step explanation:
I multiplied 17.25 times 37. The product was $638.25.
I was a bit confused when it said,"His overtime rate is 1 times his regular hourly rate." Since it is 1 times his hourly rate, it shouldn't affect the answer.

Find the conjugate and product of
2-i5
Answer: [tex]2+i5,\ 29[/tex]
Step-by-step explanation:
Given
Complex number is [tex]2-i5[/tex]
Its conjugate is obtained by changing the sign of the original number i.e. [tex]2+i5[/tex]
The product of the two numbers is
[tex]\Rightarrow (2-i5)(2+i5)=2^2-(5i)^2\quad \quad [(x+y)(x-y)=x^2-y^2]\\\\\Rightarrow (2-i5)(2+i5)=4-25i^2\\\\\Rightarrow (2-i5)(2+i5)=4+25=29[/tex]

Answer:
At 5% level of significance the conclusion of the test is that the number of intervals used to test the hypothesis is : 5
Step-by-step explanation:
At 5% level of significance the conclusion of the test is that the number of intervals used to test the hypothesis is : 5
since each interval contains equal number of values lets divide the data into 6 groups i.e. frequency in the third group = 30 /6 = 5
hence we can say that the number of intervals used to test the hypothesis is 5

At a Marine Corps military base there is a barbershop where the actual output from each chair is 12 haircuts per hour. It operates with an efficiency of 85%. If the base needs to have 650 haircuts a day how many barber chairs should there be if the barber shop is open 10 hours per day
Answer:
Barbers= 5.41= 6 barbers
Step-by-step explanation:
Giving the following formula:
Haircuts per hour= 12
Number of hours= 10
Haircuts needed= 650
First, we need to calculate the number of haircuts each barber can make per day:
Haircuts per barber a day= 12*10= 120 haircuts
Now, the number of barbers needed:
Barbers= total haircuts / haircuts per day
Barbers= 650/120
Barbers= 5.41= 6 barbers

15. The area of a rectangular playground is 315 yd? The width of the playground is 6 yd longer than its
length. Find the length and width of the playground.
Answer:
length 21yd
width 15yd
Step-by-step explanation:
Actually it does factor
x(x+6)=315
x²+6x=315
x² +6x - 315 = 0
(x+21)(x-15) = 0
x= -21. discard as can’t have a negative distance
x=15
So dimensions are 15 and 21

THE TOPIC IS: AREA OF CIRCLES!! PLEASE HELP ME WITH THIS QUESTION!!! WHATS THE ANSWER?? I WILL GIVE YOU BRAINLIEST AND A THANKS!!! AND PLS PUT AN EXPLANATION!! THANK YOU GUYS SO MUCHHHH!! CAN YOU PLEASE DO BOTH OF THESE!!!
Step-by-step explanation:
8) Area of circle =
[tex]\pi {r}^{2} [/tex]
Radius = 1/2 of diameter (Diameter = 2x radius)
Radius = 1/2 × 10 in = 5 in.
Area of circle =
[tex]\pi {5}^{2} = 25\pi {in}^{2} [/tex]
11) Radius = 1/2 × 6m = 3m
Area of Circle =
[tex]\pi {3}^{2} = 9\pi {m}^{2} [/tex]
Note that I will leave both answers in terms of pi as I am not sure how you want to leave your answer as.
Answer:
area = πr×r
r = d/2
area = π (d/2)×(d/2)
so for problem 8,
area = pi×5×5 = 25π = 78.539 inches squared

find the area of the shaded segment of the circle
9514 1404 393
Answer:
(3/2π -(9/4)√3) m² ≈ 0.8 m²
Step-by-step explanation:
The area of the segment is the difference between the area of the sector and the area of the triangle.
sector area = 1/2r²α . . . . where r is the radius and α is the central angle in radians
triangle area = 1/2r²·sin(α) . . . . same variable definitions
Then the area of the segment is ...
segment area = sector area - triangle area
segment area = (1/2)r²(α -sin(α))
The central angle subtended by the segment is 360° -300° = 60° = π/3 radians
Then the segment area is ...
A = (1/2)(3 m)²(π/3 -√3/2) = (3/2π -(9/4)√3) m² ≈ 0.8 m²
