Heracio used the computer 4 more hours to do homework than shop online.
How to solve the proportionTo find out how many more hours Heracio used the computer to do homework than shop online, we first need to calculate the number of hours he spent on each activity.
Let's start by calculating the number of hours Heracio spent on each activity:
Shopping: 10% of 40 hours = 4 hours
Videos: 15% of 40 hours = 6 hours
Homework: 20% of 40 hours = 8 hours
Games: 20% of 40 hours = 8 hours
Social media: 25% of 40 hours = 10 hours
Now, to find out how many more hours Heracio used the computer to do homework than shop online, we need to subtract the number of hours spent shopping from the number of hours spent on homework:
8 hours (homework) - 4 hours (shopping) = 4 hours
Therefore, Heracio used the computer 4 more hours to do homework than shop online.

g of x equals f of the quantity of one fourth times x end quantity
g(x) = 4f(x)
g(x) = f(4x)
The transformation of f(x) that will produce g(x) is given as follows:
g(x) = f(x)/4.
How to obtain the function g(x)?If we observe at the table, we have that each value of g(x) is one fourth of the value of the function f(x).
Hence the transformation of f(x) that will produce g(x) is given as follows:

Find f(g(1)) and g(f(1))
F(x)=x^2+2;g(x)=2x-5
Answer:
Step-by-step explanation:
Given the functions f(x) = x^2 + 2 and g(x) = 2x - 5, we can find f(g(1)) and g(f(1)) by evaluating the inner function first and then using its result as the input for the outer function.
First, let’s find f(g(1)). We start by evaluating the inner function g(1):
g(1) = 2 * 1 - 5 = -3
Now we can use this result as the input for the outer function f(-3):
f(g(1)) = f(-3) = (-3)^2 + 2 = 9 + 2 = 11
Next, let’s find g(f(1)). We start by evaluating the inner function f(1):
f(1) = 1^2 + 2 = 3
Now we can use this result as the input for the outer function g(3):
g(f(1)) = g(3) = 2 * 3 - 5 = 6 - 5 = 1
So, f(g(1)) = 11 and g(f(1)) = 1.

Verify the given linear approximation at a = 0. Then use a graphing calculator or computer to determine the values of x for which the linear approximation is accurate to within 0.1. (Round your answers to three decimal places. Enter your answer using interval notation.)
sin−1(x) ≈ x
Therefore, the linear approximation sin⁻¹(x) ≈ x is accurate to within 0.1 when x is in the interval [-0.099, 0.099].
What is function?In mathematics, a function is a relationship between two sets, called the domain and range, such that for each element in the domain there is exactly one element in the range. In other words, a function assigns a unique output value to each input value. Functions are typically denoted using a rule or formula that describes how to calculate the output value based on the input value.
Here,
The linear approximation of sin⁻¹(x) at a = 0 is given by:
sin⁻¹(x) ≈ x
To verify this, we can take the derivative of sin⁻¹(x) and evaluate it at x = 0:
d/dx(sin⁻¹(x)) = 1/√(1-x²)
d/dx(sin⁻¹(x))|x=0 = 1
Since the derivative of sin⁻¹(x) evaluated at x = 0 is equal to 1, we can use the linear approximation sin⁻¹(x) ≈ x near x = 0.
To determine the values of x for which the linear approximation is accurate to within 0.1, we can use a graphing calculator or computer to plot the graphs of sin⁻¹(x) and x, and find the intervals where the difference between the two functions is less than or equal to 0.1.
Using a graphing calculator, we can plot the two functions and find the intervals where the difference is less than or equal to 0.1. The result is:

Tyler will need a amount of 79,200 grams (or 79.2 kilograms) of glitter to cover the prism completely.
To calculate the amount of glitter needed to cover the prism completely, we first need to find the total surface area of the prism.
The prism consists of five faces: two rectangular faces with dimensions 18 m x 10 m, two triangular faces with base 18 m and height 10 m, and one rectangular face with dimensions 18 m x 25 m.
The total surface area of the prism can be calculated by adding the areas of all the faces together:
Total Surface Area = 2(18 m x 10 m) + 2(0.5 x 18 m x 10 m) + 18 m x 25 m
Total Surface Area = 360 m² + 180 m² + 450 m²
Total Surface Area = 990 m²
Given that 80 g of glitter is needed to cover each m², we can now calculate the total amount of glitter needed:
Total Glitter = Total Surface Area x Glitter per m²
Total Glitter = 990 m² x 80 g/m²
Total Glitter = 79,200 g
Therefore, Tyler will need 79,200 grams (or 79.2 kilograms) of glitter to cover the prism completely.

a group of students were asked if they are in the math club and if they are in the literature club. Partial results are shown in the table. What is the value of x+y?
Hence Option A. 22 is correct.
How to solveOf the students in the maths club , 67% are not in the literature club.
So the number of students in Maths club =
[ ( Number of students in maths club but not in the literature club) / 67 ] * 100 % = [ 16 / 67 ] * 100% = 24 (Rounded)
Hence, Number of students in maths club and in the literature club =
x = Total Number of students in Maths club - Number of students in maths club but not in the literature club
x = 24 - 16 = 8
Of the students not in the maths club , 78% are not in the in the literature club.
So, Of the students not in the maths club , 100% - 78% = 22% are in the literature club.
So the number of students not in the Maths club =
[ ( Number of students not in the maths club and in the literature club) / 22 ] * 100 %
= [ 4 / 22 ] * 100% = 18.18 = 18 (Rounded)
Hence, Number of students not in the maths club and not in the literature club =
y = Total Number of students not in the Maths club - Number of students not in the maths club and in the literature club
y = 18 - 4 = 14
So, x + y = 8 + 14 = 22.

Assume that the speed of automobiles on an expressway during rush hour is normally distributed with mean of 62 mph and a standard deviation of 5 mph.
What percent of cars are traveling slower than 55 mph?
About 8.08% of cars are traveling slower than 55 mph during rush hour on this expressway.
To solve this problemUsing the provided mean and standard deviation, we must standardize the value of 55 mph before determining the equivalent area under the standard normal distribution curve.
The standardized value, or z-score, is calculated as:
z = (x - μ) / σ
Where
x is the value we want to standardize (in this case, 55 mph) μ is the mean (62 mph)σ is the standard deviation (5 mph)Plugging in the values, we get:
z = (55 - 62) / 5 = -1.4
The area under the usual normal distribution curve to the left of z = -1.4 must now be determined. Using a common normal distribution table, we can determine that this area is roughly 0.0808.
Therefore, about 8.08% of cars are traveling slower than 55 mph during rush hour on this expressway.

The volume of a suitcase is 8,556 Cubic
inches. It is 32 inches long and 15.5
inches high. Write an equation to
represent the width. Then find the width
of the suitcase.
To find the width of the suitcase, we need to use the formula for the volume of a rectangular prism:
Volume = Length × Width × Height
Given the volume of the suitcase as 8,556 cubic inches, the length as 32 inches, and the height as 15.5 inches, we can write the equation:
8556 = 32 × w × 15.5
Simplifying this equation, we can divide both sides by the product of 32 and 15.5:
8556 ÷ (32 × 15.5) = w
Solving for w, we get:
w ≈ 16.50 inches
Therefore, the width of the suitcase is approximately 16.50 inches.

the infinite sum of a geometric sequence where |r | < 1.
The formula for the partial sum of a geometric sequence with first term a₁, common ratio r, and n terms is given by:

How to explain the formulaA geometric sequence is a non-zero numerical sequence in which each term after the first is found by multiplying the preceding one by a fixed, non-zero quantity known as the common ratio.
In the formula, Sₙ is the sum of the first n terms of the sequence.
Alternatively, the formula can be expressed as:
Sₙ = (a₁(rⁿ - 1))/(r - 1)
