The slopes 0/3 and 9/0 are not perpendicular .
In the question ,
the two slopes are given ,
the value of slope 1 (m₁) = 0/3
the value of slope2 (m₂) = 9/0 .
We know that the two slopes m₁ and m₂ are perpendicular is
m₁ × m₂ = -1 .
So , for the given values ,
On substituting the values of m₁ and m₂ ,
we get ,
= (0/3) × (9/0) ≠ -1

The perimeter of rectangle ABDC is 61.24 units.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The rectangle ABDC is given in the question which has:
AB = 8 and AC = 24
Here AC is the diagonal of the rectangle which is the hypotenuse in a right triangle.
As per Pythagoras's theorem,
AC² = AB² + BC²
24² = 8² + BC²

Give your answer as an expression in
terms of π.
The perimeter of this semi-circle with diameter, d = 84cm the expression in terms of π are as follows:
= 48π + 42
What is the equation for a semicircle?The area of a circle, A, is calculated using the formula A = pi * r2, where r is the circle's radius. Since we already know that a semicircle is half of a circle, we can easily divide that equation by two to determine the area of a semicircle. As a result, A = pi * r2/2 is the formula for calculating the area of a semicircle.
How do you calculate the circumference of a half-semicircle?With the aid of the following formula, we can determine a semicircle's perimeter: The semicircle's perimeter is equal to r + 2r units, where r is the radius of the semicircle.
According to the given data:Diameter of the semi-circle = 84cm
Now,
the circumference of the semi-circle = πr + 2r
Substituting the value of r in the given formula:
the circumference of the semi-circle = πr + 2r
= πr + 2r
= 48π + 42
The perimeter of this semi-circle with diameter, d = 84cm the expression in terms of π are as follows:

Reflected across the y-axis
Shifted down 5 units
The given function shifted 3 units left is log(x+3), vertical compression by factor 2 is 2log(x+3), Reflection across the y-axis is 2log (-x+3) and shifted down by 5 units is 2log(-x+3)-5.
Given the parent function with base 10.
We want to find the given transformations.
The given parent function is y=log(x)
Firstly, we want to shift the given parent function 3 units left means we will add 3 in the parent function, we get
y=log(x+3)
Now, we want to do vertical compression by a factor of 2 means we will multiply the above function with 2, we get
y=2log(x+3)
Further, we want to reflected the above function across the y-axis means we will multiply the x with minus, we get
y=2log(-x+3)
Furthermore, we want to shift the above function down with 5 units means we will subtract 5 from the above function, we get
y=2log(-x+3)-5
Hence, the given parent function y=log(x) when shifted 3 units left is log(x+3), vertical compression by factor 2 is 2log(x+3), Reflection across the y-axis is 2log (-x+3) and shifted down by 5 units is 2log(-x+3)-5.

What is meant by volume?Volume is a measure of three-dimensional space that is occupied. It is frequently quantified numerically using SI-derived units (such as the cubic metre and litre) or various imperial units (such as the gallon, quart, cubic inch). The definition of length (cubed) is related to volume. The volume of a container is commonly understood to be its capacity; that is, the amount of fluid (gas or liquid) that the container can hold, rather than the amount of space it occupies.
Volume was measured in ancient times using similar-shaped natural containers, and later, standardized containers. Arithmetic formulas can easily calculate the volume of some simple three-dimensional shapes. Volumes of more complicated shapes can be calculated using integral calculus if a formula is provided.
The volume of the cylindrical is,
V = πr²h
V = volume
r = base radius
h = height
Calculate the difference between both sides of the equation in relation to time t. Because the radius r does not change over time, we can consider it a constant:
dv/dt = πr²(dh/dt)
Given,
dv/dt =555 cubic cm per second
r = 15
solve dh/dt:
555 = π(15)²(dh/dt)
dh/dt = 555(7/22)(1/225)

Given that the delivery person works an 8-hour shift, he needs 4 gallons of gasoline in his tank.
A function is defined as the expression that relates a independent variable with a dependent variable. To evaluate a function is to substitute the value of the independent variable and then calculate the function value.
Given that the delivery person works an 8-hour shift, substitute x = 8 to the function of y.
y = f(x) = x² + 3x
y = 8² + 3(8)
y = 88
To determine the amount of gasoline needed, substitute the value of y to the function of g of y.
g = y / 22
g = 88 / 22
g = 4
