Step-by-step explanation:
The parent graph is
f(x)=x
If this graph is transformed to obtain
g(x)=f(x)−4
The subtracttion means the graph will shift downward vertically
The graph of g(x) is obtained by shifting f(x) down by 4 unit.

Step-by-step explanation:
Your answer is accurate, but it's not the most precise option.
f(x) is decreasing and concave up on the interval. Therefore, trapezoidal rule will give us an area greater than the actual area, but closer than left-hand rule.
If f(x) were a straight line, then midpoint rule would give us the same area as trapezoidal rule. However, since f(x) is concave up, the midpoint is less than the average of the endpoints. So midpoint rule will give us an area less than the actual area, but closer than right-hand rule.
in January the depth of a lake was 943 feet in August the depth of the lake was 754.4 what is the percentage decrease of the depth of the lake from January to August
Answers
The percentage decrease of the depth of the lake from January to August is 20%.
What is percentage decrease?The difference between the initial and final numbers is shown as a percentage reduction. It displays a percentage loss of value compared to the original regardless of the units. The decrease is equal to the initial amount less the final amount.
Given,
The depth of lake in January = 943 feet
The depth of lake in August = 754.4 feet
The difference is = (943-754.4) feet
= 186.6 feet
So, the percentage decrease of the depth of the lake from January to August will be = (186.6 ÷ 943) × 100
= 20%
Therefore, the answer is 20%.

Calculate the size of x, y and z
Answers
The value of angle x is 44⁰.
The value of angle y is 46⁰.
The value of angle z is 46⁰.
What is the value of angle x, y and z?The value of angle x, y and z is calculated as follows;
m∠ADB = ¹/₂ m∠AOB (angle at center is twice angle at circumference)
m∠ADB = ¹/₂ x 88⁰
m∠ADB = 44⁰
x = 44⁰
The value of angle y is calculated as follows;
since line AC is the diameter, the sum of angle x and angle y must sum up to 90 degrees.
y = 90 - 44
y = 46⁰
The value of angle z is calculated as follows;
line OA = line OB, since both are radius of the circle.
So triangle AOB is isosceles triangle, and angle A and B are equal.
m∠OAB = m∠OBA = z
z + z + 88 = 180 (sum of angles in a triangle)
2z = 92
z = 92/2
z = 46⁰

We have the following information:
n = 25, p-value = 0.0667
Besides that H0 is not rejected.
With this information we can affirm that the highest possible significance level you can have is 95%
Because alpha = 0.05
We reached this conclusion thanks to the fact that:
p-value> 0.05 hence we do reject the null hypothesis

Answers
Carlos needs to earn at least 16 points on the final quiz to earn at least a 90% average.
We have,
Let's start by finding the total number of points that Carlos can earn in the class:
Total points
= 5 quizzes x 20 points per quiz
= 100 points
If Carlos needs an average of 90% or greater, that means he needs to earn at least 90 points out of 100.
Total points earned.
= 18 + 19 + 17 + 20
= 74 points
To find the minimum score Carlos needs on the final quiz, we can set up an inequality:
(74 + x) / 5 ≥ 0.9
where x is the score on the final quiz.
Simplifying this inequality.
74 + x ≥ 90
x ≥ 16

Petra jogs 6 miles in 42 minutes. At this rate, how long would it take her to jog 8 miles?
Answers
Distance 1 / Time 1 = Distance 2 / Time 2
Using the information given:
6 miles / 42 minutes = 8 miles / Time 2
To solve for Time 2, we can cross-multiply and then divide:
6 miles * Time 2 = 8 miles * 42 minutes
6 * Time 2 = 8 * 42
6 * Time 2 = 336
Now, we divide both sides by 6 to isolate Time 2:
Time 2 = 336 / 6
Time 2 = 56 minutes
Therefore, it would take Petra 56 minutes to jog 8 miles at the same rate.
Answer:
56 minutes
Step-by-step explanation:
We can use proportions to solve.

Perimeter add all the sides.
so let's walk around and combine like terms:
starting on the bottom moving to the left.
3x^2 + x^2= 4x^2 (there are no other squared terms)
back to the bottom moving left again:
-11x-3x+3x+x = -10x (-3x + 3x =0)
so -11x + x = -10x
now add all of the constants

The line plot above shows the amount of olive oil, in ounces, used in 13 different pizza recipes. Isabella wants to make one pizza from each of the recipes. Will she have enough olive oil to make the pizzas if she buys a 16-ounce bottle of olive oil? Explain or show your reasoning.
Answers
By adding all the numbers in the line plot, we conclude that she will have enough olive oil.
Will she have enough olive oil for the 13 recipes?To check this, we just need to add the 13 numbers and see if it is more than 16.
Each point above the line plot means how many times that number will apear in our sum, then the sum will be:
(2*0 + 4*(4/8) + 3*(6/8) + 3*1 + (1 + 2/8))
Now we need to solve that:
(2*0 + 4*(4/8) + 3*(6/8) + 3*1 + (1 + 2/8))
= 2 + 9/4 + 3 + 1 + 1/4
= 2 + 3 + 1 + 9/4 + 1/4
= 6 + 10/4
= 6 + 8/4 + 2/4
= 6 + 2 + 1/2
= 8 + 1/2
That is the amount of ounces of oil that she needs for the 13 recipes, it is less than 16 ounces, so she will have enough oil.

The distance between Bloemfontein and Upington is a distance of 582 kilometers. The distance between two cities may vary depending on the route taken, traffic, and other factors. The distance between these two cities is measured in a straight line, which may not be the actual road distance.
To determine the distance between Bloemfontein and Upington, we used the Haversine formula, which computes the shortest distance between two points on the surface of a sphere. We first begin by finding the latitude and longitude of the two cities.Bloemfontein is located at -29.1211° latitude and 26.2140° longitude.Upington is located at -28.4478° latitude and 21.2561° longitude.Using the Haversine formula, we can determine that the distance between the two cities is about 582 kilometers.Sphenathi's statement that the distance from Bloemfontein to Upington is 16.3 kilometers is incorrect. Perhaps they mistakenly calculated the distance between two points within the cities. They could also have made a typographical mistake while writing their statement.
