Mark all the relative minimum points in the graph.
Please help I don't understand what to do.
Answer:
Step-by-step explanation:
The thing to remember is that absolute can be relative but relative can't be absolute. In other words, absolute min is the very lowest point on the graph and there's usually only one (unless there are 2 absolute mins that have the same y value) while relative mins can occur at several points on a graph. That means that the only relative min point on the graph occurs at (-3, 4); the absolute min occurs at (5, -6).

3) Sabina has a box containing bottles of juice. The three flavorsare
orange, mango and apple. The ratio of these flavor’sis 3 : 5 : 4 There are 35
bottles of mango juice. How many bottles are there altogether?
A )12 B) 28 C) 49 D) 84
Answer:
D
Step-by-step explanation:
sum the parts of the ratio, 3 + 5 + 4 = 12 parts
Mango has 5 parts and there are 35 bottles of mango , so
35 ÷ 5 = 7 ← value of 1 part of the ratio
In total there are 12 parts, then
total bottles = 12 × 7 = 84 → D

If tanx+cotx=2 then Cosx =?
Answer:
sqrt(2)/2
Step-by-step explanation:
tan(x) and cot(x) are both 1 when x=pi/4 and since 1+1=2, then we just need to evaluate cos(pi/4) which equals sqrt(2)/2.

What is the hundredth term in the sequence 15, 22, 29, 36, 43…?
A. 50
B. 78
C. 700
D. 708
Answer:
708
Step-by-step explanation:
We are adding 7 each time
15+7 = 22
22+7 = 29
29+7 = 36
So the common difference is 7
The first term is 15
The formula is
an = a1+d(n-1) where n is the term number
an = 15+7(n-1)
We want to find the 100th term
a100 = 15+7(100-1)
a100 = 15+7(99)
= 15+693
= 708
What is the measure of DG?
Enter your answer in the box.
Answer:
Step-by-step explanation:
∠DHG is an inscribed angle. This angle, by definition, measures half the measure of its intercepted arc. The intercepted arc is arc DG, the one in question. This means that, by the rule, if the angle is 85 degrees, the arc is 2(85) = 170°

The students in Shawn's class got to choose whether to visit the zoo or the aquarium. 3 students went to the zoo and 15 students went to the aquarium. What is the ratio of the number of students who went to the zoo to the number of students who did not go to the zoo?
A. 1:6
B. 1:1
C. 1:3
D. 1:5
Answer:
D. 1:5
Step-by-step explanation:
3 students went to the zoo
15 students went to the aquarium, which is no the zoo
students who went to the zoo : students who did not go to the zoo =
= 3:15
Now we simplify the ratio by dividing both numbers by 3.
= 1:5

You are taking a survey on the heights of all your classmates. This is an example of categorical data.
True or false
The given statement is false as taking a survey on the heights of all your classmates is an example of quantitative data.
Quantitative data is data that can be measured and expressed as numbers,
such as height, weight, age, etc. Categorical data, on the other hand, consists of distinct categories or groups, such as eye color, gender, favorite color, etc.
Data can be classified into two main types: quantitative data and categorical data.
Quantitative data:
Quantitative data is numerical data that represents measurements or quantities.
It deals with things that can be measured and expressed as numbers.
For example, the heights of people, the weights of objects, the ages of individuals, and the temperatures in degrees are all examples of quantitative data.
Quantitative data can be further divided into two subtypes: discrete and continuous data.
Discrete data: Discrete data consists of whole numbers that cannot be further divided into smaller parts.
For example, the number of students in a class, the number of cars in a parking lot, and the number of books on a shelf are all examples of discrete data.
Continuous data: Continuous data consists of real numbers that can take on any value within a specific range.
For example, the height of a person can be measured as 165.5 cm, 170.2 cm, 178.9 cm, etc. These are all examples of continuous data.
Categorical data:
Categorical data, also known as qualitative data, involves the grouping of items into categories or classes.
It represents characteristics or attributes and is not numerical in nature. Categorical data is further divided into two subtypes: nominal and ordinal data.
Nominal data: Nominal data consists of categories with no intrinsic order or ranking.
For example, eye color ( blue, brown, green) and types of fruits (e.g., apple, banana, orange) are examples of nominal data.
Ordinal data: Ordinal data consists of categories with a meaningful order or ranking.
However, the differences between the categories are not quantifiable.
For instance, educational levels (elementary, middle, high school) and satisfaction levels (very satisfied, satisfied, neutral, dissatisfied, very dissatisfied) are examples of ordinal data.
The height survey of classmates, the data collected would be numerical values representing the heights of each individual.
Since heights are measured and expressed as numbers, this falls under quantitative data, not categorical data.

532 - 308 is the same as blank - 300
Answer:
524
Step-by-step explanation:
First find the number we want to find
532 - 308 = 224
Set blank -300 equal to the number
blank - 300 = 224
Add 300 to each side
blank -300+300 = 224+300
blank = 524
The triangle below is equilateral. Find the length of side x in simplest radical form with a rational denominator.
Answer:
12
Step-by-step explanation:
Since it's a equilateral triangal all sides are equal.
First you double 6 since that is a right angle in the triangle the other side will have the same length. 6x2=12.
.The conversion of square feet to square yards can be represented by direct variation. Three square yards are equivalent to 27 square feet. Let y represent the number of square yards and x the number of square feet. Then y varies directly with x.
What is the constant of variation?
What is the equation representing the direct variation?
Answer:
The constant of variation is 1/9
The equation representing the direct variation is y/x= 1/9
Step-by-step explanation:
In direct variation, y/x=k denotes the equation, with k being the constant of variation. Here, y is the number of square yards and x is the number of square feet. Therefore, as we know that 27 square feet = 3 square yards, we can write one point (x₁, y₁) as (27 square feet, 3 square yards). Plugging x₁ and y₁ into our equation, we get
y/x = k
3 / 27 = k
(3/27) / (3/3) = 1/9* = k
Therefore, the constant of variation is 1/9
Next, as stated previously, y/x = k represents the equation of direct variation. Therefore, y / x = 1/9 as our equation
* because 3 is a factor of both 3 and 27, we can divide both the numerator and denominator by 3 to keep the fraction the same but also simplify it. One way to find the greatest common factor is to list the factors of each number and see the highest number that is a factor of both
The constant of variation is "1/9" and the equation representing the direct variation is y = (1/9)x.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation of direct variation is given by,
y = kx ....(i) where "k" is a constant.
Let y represent the number of square yards and x the number of square feet. Then y varies directly with x.
Given that y varies directly with x, and x = 27, then y = 3.
Substitute the values of y = 3 and x = 27 in the direct variation equation and solve for k:
⇒ 3 = 27k
⇒ k = 3/27
⇒ k = 1/9
Substitute the values of k = 1/9 in the direct variation equation :
⇒ y = (1/9)x
Thus, the constant of variation is "1/9" and the equation representing the direct variation is y = (1/9)x.
