Answer: A property occurring in the example 11.5 + (-11.5) = 0, is additive inverse.
Step-by-step explanation:
A property where sum of any number and its inverse is equal to zero is called additive inverse property.
For example, 11.5 + (-11.5) = 0
Here, 11.5 is the number and its inverse is (-11.5). The sum of both these is equal to zero. Hence, it shows a property of additive inverse.
Thus, we can conclude that property occurring in the example 11.5 + (-11.5) = 0, is additive inverse.
A geyser erupts every 25 minutes. A hiker has not consulted a schedule before heading to see the geyser, so the amount of time he spends waiting to see an eruption follows a uniform distribution. What is the probability that he will wait longer than 6 minutes? Give your answer to two decimal places.
Answer:
0.76 = 76% probability that he will wait longer than 6 minutes
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distribution has two bounds, a and b, and the probability of finding a value higher than x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
A geyser erupts every 25 minutes. A hiker has not consulted a schedule before heading to see the geyser, so the amount of time he spends waiting to see an eruption follows a uniform distribution.
This means that [tex]a = 0, b = 25[/tex]
What is the probability that he will wait longer than 6 minutes?
[tex]P(X > 6) = \frac{25 - 6}{25 - 0} = 0.76[/tex]
0.76 = 76% probability that he will wait longer than 6 minutes

Answer:
D
Step-by-step explanation:
If a = 38 and b = 26 then the equation would be y^2/1444 + x^2/676 = 1
also just graph it or smth
The equation of the ellipse in the figure is x^2/676 + y^2/1296 = 1
How to determine the equation?The figure is an ellipse, and it has the following parameters:
Center, (h,k) = (0,0)Major radius = 36Minor radius = 26The equation of the ellipse is then calculated using:
x^2/r^2 + y^2/R^2 = 1
So, we have:
x^2/26^2 + y^2/36^2 = 1
Evaluate the exponents
x^2/676 + y^2/1296 = 1
Hence, the equation of the figure is x^2/676 + y^2/1296 = 1

find the length of the third side. if necessary, write in simplest radical form.
Answer:
6
Step-by-step explanation:
its a right angle so to find a side use a Pythagorean theorem
Pythagorean theorem =
[tex]a^2+b^2=c^2[/tex]
[tex]a^2+b^2[/tex] are the sides
[tex]c^2[/tex] is the hypotenuse
In this case we need the hypotenuse
[tex]3\sqrt{3} ^2 + 3^2 = c^2[/tex]
[tex]27 + 9=c^2[/tex]
[tex]36=c^2[/tex]

find,

100
Answer:
x = 400 when y = 100
Step-by-step explanation:
This is a question in relation to direct variation.
y ∝ [tex]\sqrt{x}[/tex]
y = k [tex]\sqrt{x}[/tex]
Given that, y = 45, x = 81. Then;
45 = k [tex]\sqrt{81}[/tex]
45 = 9k
k = [tex]\frac{45}{9}[/tex]
k = 5
Thus the relationship among the variables is;
y = 5 [tex]\sqrt{x}[/tex]
If y = 100, then;
100 = 5 [tex]\sqrt{x}[/tex]
[tex]\sqrt{x}[/tex] = [tex]\frac{100}{5}[/tex]
[tex]\sqrt{x}[/tex] = 20
x = [tex](20)^{2}[/tex]
x = 400
Therefore, x = 400 when y = 100.

The manager of an apartment complex is ordering new tile to lay around the perimeter of the apartments swimming pool. The specifications for the pool are shown below. The solid lines represent the perimeter of the pool.
What is the approximate perimeter of the pool?
Answer: 158 feet
Step-by-step explanation: I’ve gotten this question right on a test.
The approximate perimeter of the pool will be 157.36 feet.
What is the perimeter of the shape?The complete stretch of a shape's border is referred to as the perimeter in geometry. A shape's periphery is calculated by summing the lengths of all of its sides and borders. Its dimensions are expressed in linear units like centimeters, meters, inches, and feet.
The perimeter of the shape is a combination of the perimeter of two small quarter circles, one big circle, and the sides of a rectangle. Then the perimeter is calculated as,
P = πr + 2L + w + πR
P = 3.14 x 9 + 2 x 35 + 12 + 3.14 x 15
P = 157.36 feet
The approximate perimeter of the pool will be 157.36 feet.

Answer:
(y^3-2)(x^2-2)
Step-by-step explanation:
x^2y^3-2y^3 can be factored. This will be equal to y^3(x^2-2). Then for the other half it will be equal to -2(x^2-2). Because the insides are the same, the equation is the outside two number y^3 and -2 added together time the inside number x^2-2. This will make the expression (y^3-2)(x^2-2).

Answer:

Step-by-step explanation: to get the total price of stock you multiply the cost of one share by how many shares were bought. After being sold years later they made a profit, you must subtract the total cost from this profit to find the total profit.
rewrite the rectangular equation x^2+y^2-8y=0 as a polar equation
Answer:
We'll use the following identities:
r = √(x2 + y2), from which we also have r2 = x2 + y2
y = r*sinθ
First, let's re-write your equation:
r = 8*sin(θ). Multiply both sides by r:
r2 = 8r sin(θ)
Now, we'll use substitute using the identities:
x2 + y2 = 8y
Re-arrange and complete the square:
x2 + y2 - 8y = 0
x2 + (y-4)2 - 16 = 0
x2 + (y-4)2 = 16
This represents a circle with center (0,4), and radius 4.
