What is the probability that a point chosen at random in the rectangle is also in the blue triangle
Answer:
The probability that a point chosen at random in the rectangle is also in the blue triangle is:
1/2
Step-by-step explanation:
We are given a figure
We have to find the probability that a point chosen at random in the rectangle is also in the blue triangle.
Area of rectangle= 4×5 sq. in.
= 20 sq. in.
The area of blue triangle=[tex]\dfrac{1}{2}\times 4\times 5[/tex]
= 10 sq. in.
P(that a point chosen at random in the rectangle is also in the blue triangle)
= area of blue triangle/whole area of the rectangle
= 10/20
= 1/2

Y= v^2/2a solve for v
Final answer:
To solve for v in the equation y = v²/2a, multiply both sides by 2a and then take the square root of both sides which gives v = √(2ay).
Explanation:
The question requires us to solve the equation y = v²/2a for the velocity v. To isolate v, we multiply both sides of the equation by 2a, then take the square root of both sides.
Multiply both sides of the equation by 2a: 2ay = v²Take the square root of both sides to solve for v: v = √(2ay)This mathematical process makes v the subject of the equation based on the given formula from kinematics. It's important to note that v will have two values, one positive and one negative, since taking the square root of a number yields both a positive and negative result.
The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. The function below shows the relationship between f(x) and x:
f(x) = 10(1.3)x
Which of the following graphs best represents the function?
Graph of f of x equals 1.3 multiplied by 10 to the power of x
Graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity
Graph of f of x equals 10 multiplied by 1.3 to the power of x
Graph of f of x equals 1.3 to the power of x
The graphs that best represents the function is:
Graph of f(x) equals 10 multiplied by 1.3 to the power of x.
Step-by-step explanation:The function that shows the relationship between f(x) and x: is:
[tex]f(x)=10\times (1.3)^x[/tex]
a)
Graph of f(x) equals 1.3 multiplied by 10 to the power of x.
This means that the expression is given by:
[tex]f(x)=1.3\times (10)^x[/tex]
Hence, option: a is incorrect since it is not equal to the given function f(x).
b)
Graph of exponential function going up from left to right in quadrant 1 through the point (0, 0) and continuing towards infinity.
In the given function f(x) when x=0 we have:
[tex]f(x)=10\times (1.3)^0\\\\\\f(x)=10\neq 0[/tex]
Hence, option: b is incorrect.
c)
Graph of f(x) equals 10 multiplied by 1.3 to the power of x.
This means that the function f(x) is given by:
[tex]f(x)=10\times (1.3)^x[/tex]
which is obviously true.
Hence, option: c is correct.
d)
Graph of (x) equals 1.3 to the power of x.
This means that the function f(x) is given by:
[tex]f(x)=(1.3)^x[/tex]
which does not m,atches the actual expression.
Hence, option: d is incorrect.

Two numbers are in the ratio of 2 to 3. If the smaller number is 18, the larger number is _____. 21 27 36 54
Answer: If two numbers are in a ratio of 2 to 3, this means that two times one number is equal to 3 times the other, or:
2*X = 3*Y, where X and Y are any numbers, and X is the bigger one and Y is the smaller one.
If Y=18, then:
2*X = 3*18 = 54
X=54/2 = 27
So the answer is 27.

Which value(s) of x would result in Set B being a function of the values in Set A? Select Function or Not a Function for each value of x. Are the following numbers a function or not a function
To determine if Set B is a function of the values in Set A, we need to ensure that each value of x in Set A has only one corresponding value in Set B:
-2: Function5: Function0: Not a Function1: Function-3: FunctionFor each value of x, we can determine if Set B is a function or not by checking if there is only one corresponding value in Set B.
For x = -2, there is only one corresponding value in Set B, so it is a function.
For x = 5, there is only one corresponding value in Set B, so it is a function.
For x = 0, there are multiple corresponding values in Set B, so it is not a function.
For x = 1, there is only one corresponding value in Set B, so it is a function.
For x = -3, there is only one corresponding value in Set B, so it is a function.
Therefore, Set B is a function of the values in Set A for all values of x except for x = 0.

A circular pool is surrounded by a circular walkway. The radius of the pool is y − 4 and the radius of the full circle formed by the walkway is y + 4. Write a polynomial that represents the area of just the walkway itself, not including the space covered by the pool. (The area of a circle is given by A = πr ^2, where r represents the radius of the circle.)
The polynomial representing the area of the walkway is the difference between the area of the large circle (π(y + 4)²) and the small circle (π(y − 4)²).
Explanation:To find the polynomial that represents the area of the walkway surrounding a circular pool, we need to calculate the difference between the area of the larger circle (walkway plus pool) and the area of the smaller circle (just the pool).
The radius of the pool is y − 4, and the radius of the walkway plus the pool is y + 4. The area of a circle is given by A = πr².
First, calculate the area of the large circle:
Area of the large circle = π(y + 4)²
Then, calculate the area of the small circle:
Area of the small circle = π(y − 4)²
Finally, the polynomial for the area of the walkway is found by subtracting the area of the small circle from the area of the large circle:
Area of the walkway = π(y + 4)² − π(y − 4)²
The polynomial that represents the area of just the walkway (not including the pool) is π(8y + 32).
Explanation:To find the area of just the walkway, we need to subtract the area of the pool from the area of the full circle formed by the walkway. The area of the pool is given by A = πr ^2, where r is the radius of the pool (y - 4). The area of the full circle is given by A = πr ^2, where r is the radius of the walkway (y + 4). Therefore, the area of the walkway is (π(y + 4) ^2) - (π(y - 4) ^2). Simplifying this expression, we get the polynomial: π(8y + 32).

Step-by-step explanation:
The owners want to hire a contractor to build a porch along side the parlor. The parlor is rectangular with width Of 32 feet and length of 50 feet. The porch will have the same width that on each side of the house. See design plans.
The width of the porch will be 32 feet, the same as the parlor. However, to calculate the amount of building materials needed, additional specifics are required such as the porch's length, location of posts, and number of boards.
Explanation:To answer the question related to designing a porch that matches the width of the parlor, we first understand that the parlor is of a rectangular shape with a width of 32 feet. Considering that the porch will have the same width, it means the porch will also have a width of 32 feet.
From this point, specifics such as the desired length of the porch, location of posts, number of boards or rails, and other related factors would come into play in the calculating of building materials needed for the construction. There may also be the need to consider factors like the ratio of width to length in the design, akin to the mathematical relation mentioned in the statement 'X = Y x 2 + 1'.
So, while we know the width of the porch because it matches the parlor, the exact amount of materials that will be required would depend on further specifics of the porch design, similar to the steps in a stoichiometry problem in chemistry where one calculates the amount of reactants or products in a chemical reaction based on known ratios.

The height of a tree was 4.8m .After one year the height of the tree was increased by 12.5%.find its new height
The new height of the tree after it has increased by 12.5% is 5.4 meters
To find the new height of the tree after it has increased by 12.5%, we start by calculating the increase in height using the following equation
Increase = 12.5% of the original height
The original height is given as 4.8m. So, the formula can be expressed as follows
Increase = 12.5% * 4.8
Increase = 0.125 * 4.8
Increase = 0.6 meters
Add the increase to the original height
New height = Original height + Increase
The above equation can then be expressed as follows
New height = 4.8 + 0.6
New height = 5.4 meters

Answer:
The scale factor is equal to [tex]0.4[/tex] or [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
we know that
If two figures are similar. then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z------> the scale factor
x------> the volume of the dilated prism
y------> the volume of the original prism
so
[tex]z^{3}=\frac{x}{y}[/tex]
we have
[tex]x=200\ ft^{3}[/tex]
[tex]y=3,125\ ft^{3}[/tex]
