which inequality is true?
a. |-15|>|-19|
b.|-16|<|13|
c.|-15|>|12|
d.|12|<|-8|
e.|-19|>|-20|
Answer:
C
Step-by-step explanation:
Absolute value makes anything in it positive, as distance from 0 can only be positive. So if we apply that to every term, we can find the answer.
For a, simplify and it becomes 15>19. That's false
For b, simplify and it becomes 16<13. Also false
For c, simplify and it becomes 15>12. True
For d, simplify and it becomes 12<8. False
For e, simplify and it becomes 19>20. Very False.
So the only true one is C. So C is the answer.
Hope this helped.

A hammock that hangs between two trees makes a parabola shape that has the equation y = 0.4(x- 3)² +1, where x is the distance from one end and y is the height above the ground, measured in meters.
A. What is the lowest point of the hammock?
B. If the hammock is attached to both trees at the same height, how far away are the trees from one another?
Answer:
A. The lowest point of the hammock is at the point 1 meters above the ground and 3 meters from one end of the hammock
B. The two trees are 6 meters away from one another
Step-by-step explanation:
The given equation of the parabola representing the hammock is as follows;
y = 0.4·(x - 3)² + 1
The general equation of a parabola is a·(x - h)² + k;
Where the coordinates of the vertex point of the parabola, which is the lowest (or highest, furthest) point on the vertex is (h, k) = (3, 1)
Therefore, we have;
A, The coordinates of the lowest point on the hammock is (3, 1)
Therefore, the lowest point of the hammock is at 1 meters above the ground and 3 meters from one end of the hammock
B. Given that the distance from one end is "x", we have;
The height at which the hammock is attached is given as the point where x = 0 as follows;
Given that the vertex of the parabola represents the axis of symmetry of the parabola, we have that the horizontal distance from one end of the hammock to the vertex point of the parabola that the hammock forms is (3 - 0) meters = 3 meters
Therefore, by the definition of symmetry, the distance from the vertex point to the other end of the parabola that the hammock forms is also 3 meters
From which we have, the distance the two trees are from one another is 3 meters + 3 meters = 6 meters.

32h+24=-3h-11h what is the solution
Answer:
h = -12/23
Step-by-step explanation:
Combine like terms:
32h + 24 = -3h - 11h
32h + 24 = -14h
Subtract 24 from both sides of the equation:
32h + 24 = -14h
32h + 24 - 24 = -14 h - 24
Simplify:
32h = -14h - 24
Add 14 to both sides and then you simplify. This will give you the answer -12/23. Good luck!!

Step-by-step explanation:
The LCM of 156 and 224
First find the highest common factor between the two number
156 = 4 * 39
224 = 4 * 56
Since 4 is the highest common factor between both numbers, the LCM of 156 and 224 will be the product of the highest common factor and the other multiples that are left when the numbers are divided by the highest common factor.
As such, the LCM of 156 and 224
= 4 * 39 * 56
= 8736

5.2 divided by blank =0.052
Answer:
divide it by 100
Step-by-step explanation:
5.2 ÷ 100 = 0.052
The required 5.2 divided by 100 gives the quotient of 0.052.
Given that,
5.2 divided by blank =0.052, A value that is best suitable for the blank is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
let the number be x,
According to the question,
5.2 / x - 0.052
x = 5.2/0.052
x = 5200/52
x = 100
Thus, the required divisor of the given numeral is 100.

Answer:
The equation of the linear function is f(x) = -3x - 4
Step-by-step explanation:
The form of the equation of the linear function is f(x) = m x + b, where
m is the slope of the line which represent the functionb is the y-intercept which is value f(x) at x = 0The rule of the slope is m = Δy/Δx, where
Δx = x2 - x1 and Δy = y2 - y1(x1, y1) and (x2, y2) are two points on the line∵ f(x) = y
∴ The coordinates of any point belongs to the function are (x, y)
∵ f(-4) = 8 and f(2) = -10
∴ The points are (-4, 8) and (2, -10)
∵ x1 = -4 and y1 = 8
∵ x2 = 2 and y2 = -10
→ Find Δx and Δy
∴ Δx = 2 - (-4) = 2 + 4 = 6
∴ Δy = -10 - 8 = -18
→ Substitute them in the rule of the slope
∵ m = [tex]\frac{-18}{6}[/tex]
∴ m = -3
→ Substitute it in the form of the equation above
∴ f(x) = -3x + b
→ To find b substitute x by -4 and f(x) by 8
∵ 8 = -3(-4) + b
∴ 8 = 12 + b
→ Subtract 12 from both sides
∵ 8 - 12 = 12 - 12 + b
∴ -4 = b
→ Substitute it in the equation
∴ f(x) = -3x + (-4)
∴ f(x) = -3x - 4
∴ The equation of the linear function is f(x) = -3x - 4

Point M is between points L and N on LN. LN
6x, LM 4x + 8, and
MN 27. Use the information to solve for x, and then find LN.
Answer:
Step-by-step explanation:
4x+8 27
L-------------M-------------------------N
<------------------ 6x -------------------->
LM = 4x+8
MN = 27
LN = 6x
LM + MN = LN
4x+8 + 27 = 6x
35 = 2x
17.5 = x
LN = 6x = 6(17.5) = 105
The correct answer to the question is: x = 17.5, LN = 105
From the question given above, we obtained the following:
LN = 6x
LM = 4x + 8
MN = 27
x =? LN =?The value of x can be obtained as follow:
LN = LM + MN
6x = 4x + 8 + 27
6x = 4x + 35
Collect like terms
6x – 4x = 35
2x = 35
Divide both side by 2
x = 35 / 2
x = 17.5Finally, we shall determine the value of LN.x = 17.5
LN =?
LN = 6x
LN = 6(17.5)
LN = 105SUMMARY:x = 17.5LN = 105Therefore, the correct answer to the question is: x = 17.5, LN = 105

A company has two manufacturing plants with daily production levels of 5x+17 and 3y-4,respectively.
Complete question :
A company has two manufacturing plants with daily production levels of 5x + 11 items and 2x - 3 items, respectively, where x represents a minimum quantity. The first plant produces how many more items daily than the second plant?
Answer:
3x + 14
Step-by-step explanation:
Given that:
Production level of plant 1 = 5x + 11
Production level of plant 2 = 2x - 3
The first plant produces how many more items daily than the second plant :
Plant 1 production - plant 2 production
(5x + 11) - (2x - 3)
Open the bracket :
5x + 11 - 2x + 3
5x - 2x + 11 + 3
3x + 14
Daily production of plant 1 exceeds that of plant 2 by 3x + 14

The half-life of a medication is 6 hours. How can I find the rate of decay to the nearest hundredth?
Answer:
The decay rate of the medication is approximately [tex]0.116\,\frac{1}{h}[/tex].
Step-by-step explanation:
If we know that amount of medication decays exponentially, this amount is represented by the following expression:
[tex]n(t) = n_{o}\cdot e^{-\lambda\cdot t}[/tex] (1)
Where:
[tex]n_{o}[/tex] - Initial amount of medication.
[tex]n(t)[/tex] - Current amount of medication.
[tex]t[/tex] - Time, measured in hours.
[tex]\lambda[/tex] - Decay rate, measured in [tex]\frac{1}{h}[/tex].
In addition, the decay rate is determined by the following formula:
[tex]\lambda = \frac{\ln 2}{t_{1/2}}[/tex] (2)
If we know that [tex]t_{1/2} = 6\,h[/tex], then the decay rate is:
[tex]\lambda = \frac{\ln 2}{6\,h}[/tex]
[tex]\lambda \approx 0.116\,\frac{1}{h}[/tex]
The decay rate of the medication is approximately [tex]0.116\,\frac{1}{h}[/tex].
