Answer:
a) 14.14 feet
b) 260.5 square feet
Step-by-step explanation:
A square has an area of 200 square feet.
a) How long is each side in simplest radical form?
Area of a square = (side length)²
Side length = √Area
Side length = √200 square feet
= 14.142135624 feet
≈ 14.14 feet
b) If I increase the length of each side by 2, what is the new area in simplest radical form?
= 14.14 feet + 2
= 16.14 feet
New area = (16.14 feet)²
= 260.4996 square feet
Approximately = 260.5 square feet
A 20-foot ladder is leaning against the side of a house so that the bottom of the ladder is 12 feet from the base of the house. Will the ladder reach a window that is 14.5 feet above the ground?

What is Pythagoras theorem?Pythagoras' Theorem states that the square of the hypotenuse side of a right-angled triangle equals the sum of the squares of the other two sides.
The hypotenuse of a triangle, which has a straight angle of 90 degrees, has a square that, according to the Pythagoras theorem, equals the sum of the squares of the other two sides.
According to the question;
A 20-foot ladder is leaning against the side of a house.
Hypotenuse H= 20 feet
The bottom of the ladder is 12 feet from the base of the house.
Base B = 12 feet
And let P be the perpendicular.
Using Pythagoras theorem
H²= P² + B²
20² =12² +P²
P²= 400-144
P²= 256
Taking the square root.
P= 16 feet.
Since the height of the ladder is 16 feet, and we have to reach 14.5 feet above the ground.
16 > 14.5
That means, the ladder will reach to the window.
Hence, Yes, the 16 feet ladder will reach to the window.

what is the distance from the focus to the vertex of a parabola with the equation
x = 1/12 (y-1)²
help please!
Answer:
3 units.
Step-by-step explanation:
In the equation x = 1/12 (y-1)², the vertex of the parabola is at the point (1,1). The focus of the parabola is located a distance called the "focal length" from the vertex.
The focal length is given by the formula f = 1/(4*p), where p is the coefficient of the x term in the standard form of the equation of the parabola.
In this case, the coefficient of the x term is 1/12, so the focal length is f = 1/(4*(1/12)) = 3. This means that the distance from the focus to the vertex is 3 units.
What is the relationship between the volumes of a rectangular prism and a rectangular pyramid whose length width and height are all equal?
The volume of the rectangular prism is 3 times the volume of the rectangular pyramid.
Consider a rectangular prism with length l, width w and height h.
The volume of the rectangular prism is:
volume of a rectangular prism = length * width * height
V1 = l * w * h
Consider a rectangular pyramid with rectangular base of length l1, width w1 and the height of pyramid is h1.
The volume of the rectangular pyramid is:
volume of a rectangular pyramid = 1/3 * base area * height
Here, base area = length * width
= l1 * w1
So, volume of a rectangular pyramid = 1/3 * base area * height
V2 = 1/3 * l1 * w1 * h1
We have been given a rectangular prism and a rectangular pyramid have equal length, width and height .
l1 = l, w1 = w and h1 = h
so, V2 = 1/3 * l * w * h
V2 = 1/3 * V1
V1 = 3 * V2
volume of a rectangular prism = 3 * volume of a rectangular pyramid
Therefore, the relationship between the volumes of a rectangular prism and a rectangular pyramid whose length width and height are all equal:

The bunny had 1/2 to eat in the morning and 1/5 left over how much did the bunny eat at night
By applying the fraction concept, we can conclude that the bunny ate 3/10 food at night.
Application of the concept of fractions in real life
In real life, the concept of a fraction is often used when we want to talk about a part of a whole, a part of something, a part of a group of people, etc.
In the problem above it is stated that initially the bunny has food, which will be eaten in the morning and at night, and some food was left over.
If x is the total food for the bunny, then the given problem can be written mathematically as follows:
breakfast (a) : a = 1/2x
dinner (b)
food left (c) : c = 1/5x
Then the mathematical expression that describes the above situation is as follows:
x = a + b + c
= 1/2x + b + 1/5x --> then we make the denominators the same, so it becomes:
x = 5/10x + b + 2/10x
= 7/10x + b
x - 7/10x = b
3/10x = b

a 600 l tank is filled with pure water. a copper sulfate solution with a concentration of 20 g/l flows into the tank at a rate of 2 l/min. the thoroughly mixed solution is drained from the tank at a rate of 2 l/min. a. write a differential equation (initial value problem) for the mass of the copper sulfate. b. solve the differential equation.
a) Differential equation (initial value problem) for the mass of the copper sulfate would be dm/dt = 0
b) m(t)=0
What is Differential equation?
A differential equation in mathematics is an equation that connects the derivatives of one or more unknown functions. Applications typically use functions to describe physical quantities, derivatives to indicate the rates at which those quantities change, and differential equations to create a relationship between the two.
a) Solution is flowing out of the tank. This can be expressed mathematically as:
dm/dt = (flow rate of solution into tank) - (flow rate of solution out of tank)
= (2 l/min) - (2 l/min)
= 0
Therefore, the differential equation for the mass of the copper sulfate in the tank is:
dm/dt = 0
This is a simple differential equation with a constant coefficient of 0, and it can be easily solved by integrating both sides of the equation with respect to time.
b. To solve the differential equation, we can write:
m(t) = integral(0, t, dm/dt)
= integral(0, t, 0)
= 0
Since the coefficient of the derivative is 0, the solution to the differential equation is a constant function with a value of 0. This means that the mass of the copper sulfate in the tank will remain constant over time, regardless of the flow rates of the solution into and out of the tank.

What is the mean and standard deviation of 1 2 3 4 and 5 respectively?
The mean of 1, 2, 3, 4, and 5 is 3, and the standard deviation is 1.58.
To find the mean, you add up all the numbers and divide by the number of numbers you have.
To find the standard deviation, you first find the difference between each number and the mean, square each of these differences, add them up, and divide by the number of numbers you have. Then, you take the square root of this result.
Mean = (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3
Standard deviation = sqrt(((1 - 3)^2 + (2 - 3)^2 + (3 - 3)^2 + (4 - 3)^2 + (5 - 3)^2) / 5) = sqrt((4 + 1 + 0 + 1 + 4) / 5) = sqrt(10 / 5) = sqrt(2) = 1.58
How to interpret a standard deviation?The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
