- For any nonquadrantal angle 0, sin 0 and csc 0 will have the same sign explain why
Answer:
Because sin 0 and csc 0 establish a relationship where one is reciprocated to the other.
Step-by-step explanation:
Sin 0 is found according to the mathematical expression Sin 0 = y / r.
The csc 0, in turn, is found through the mathematical expression Csc 0 = 1 / sin 0, which is equivalent to y / r.
In both expressions the letter "r" will always be represented by a positive value. This makes Csc 0 and sin 0 have a strong reciprocity and assume the same sign, regardless of the number that represents the "Y". This is because if "y" has a positive value, both sin 0 and csc 0 will have a positive sign, if "Y" will take a negative value, both sin 0 and csc 0 will take negative signs.

Find the Cardinal number of the set of all solutions to x^2=100
Answer: 2
Step-by-step explanation:
this is the answer knewton alta said
The Cardinal number of the set of all solutions to x²=100 is 2.
What is Number system?A number system is defined as a system of writing to express numbers.
Cardinal numbers are natural numbers or positive integers. The smallest cardinal number is 1.
We have to find the Cardinal number of the set of all solutions to x²=100
To find the solution of the equation we have to take square root on both the sides' x=10, -10
The set of solutions will be {-10, 10}
It has two terms. Hence cardinal number is 2.
Hence, the Cardinal number of the set of all solutions to x²=100 is 2.

Step-by-step explanation:
Given AP
3,a,b,c,375th term is 37, then common difference is;
37 = 3 + 4d ⇒ d = 34/4 = 8.5Then the 2nd, 3rd and 4th terms:

A map has a scale of
2 in. = 18 mi. If you measured the distance between two cities to
be 16 in. on the map, how many miles would it actually be?
Answer:
it would be 144 miles
Step-by-step explanation:
We start by a ratio of map to mile = 2:18
if we see that the map distance is 16, 16:?
We divide 16 by 2 to get 8, so we enlarge the 2, 8 times, and we get 16
the 18, also has to be enlarged, so 18x8 = 144

The progression of their cancer was monitored, and researchers documented the This study is an example of:_______ study The survival time is the _______ variable. The type of diet is the _______ variable.
Answer:
- This study is an example of Experimental study
- The survival time is the dependent variable.
- The type of diet is the independent variable.
Step-by-step explanation:
I) This research study is an experimental study because it makes use of a scientific approach using 2 variables which in this case are organic diet and survival time.
II) Survival time is the dependent variable because it depends on the response of the patients to the organic diet.
III) Type of diet is the independent variable because it doesn't depend on any other factor or variable.
Samantha conjectures that for x < - 1 it is true that x ^ 5 - 2 > x her conjecture correct? Why or why not?

Determine if the conjecture is true
To determine if it's true or not, we have to substitute the values of x in [tex]x^5 - 2 > x[/tex]
In the first inequality, we have that [tex]x < -1[/tex]
This means that the values of x are: -2. -3, -4......

Step-by-step explanation:
So we have the equation:
[tex](\frac{9}{4}x+6)-(-\frac{5}{4}x-24})[/tex]
First, distribute the negative on the right:
[tex]=(\frac{9}{4}x+6)+(\frac{5}{4}x+24})[/tex]
Combine like terms:
[tex]=(\frac{9}{4}x+\frac{5}{4}x})+(6+24)[/tex]

Then, p and q are said to be directly proportional to each other if
p = kq
where k is some constant number called constant of proportionality.
If y varies directly with x and y = 5 when x= 8 . then we need to find y when x = 4
Therefore, y = kx
k = y/x
k = 5/8
Then y = kx
y = (5/8)4
y = 5/2

What is the theoretical probability of a 5 or 6?
_Answer as a fraction. (5 pts)
What is the experimental probability 5 or 6?
Answer as a fraction. (5 pts)
Answers:
Theoretical probability of 5 or 6 is 1/3
Experimental probability of 5 or 6 is 9/25
======================================================
Explanation:
For the theoretical probability, we ignore the table of values. We assume the cube will land on any of the 6 sides with equal probability.
So landing on any given side has probability 1/6. Landing on 5 or 6 has probability 2*(1/6) = 2/6 = 1/3.
---------
For the experimental probability, we use the table. We see that '5' shows up twice, and '6' shows up seven times. In total, those values show up 2+7 = 9 times out of 25 total.
So that's how I got 9/25.
Simplifying the fraction 30/81
Answer:
10/27
Step-by-step explanation:
First of all, to simplify a fraction, you have to find a common factor for each of the numbers. First, we know that 30 and 81 can be divided by 3, which will result in the number 10 and 27. Since 10/27 don't have any common factors, you cannot simplify it further.
The area of the base is 1·/4ft^2 . What is the volume of the cube?
Answer:
1/8 ft^3
Step-by-step explanation:
The cube has equal sides. So u square root the base area and u get 1/2 ft. The length, width and height are all 1/2. So u cube the 1/2. Your final answer would be 1/8 ft^3.
V = 1/8 ft³
Step-by-step explanation:Area of the base = 1/4 ft² = l²
l² = 1/(2)² ft²
l = 1/2 ft
V = l³
= (1/2 ft)³
= 1/2³ ft³
= 1/8 ft³

Answer:
90 cups
Step-by-step explanation:
First, let's calculate how much cups of sugar we need for 1 batch of chocolate chip.
45 / 4 = 11.25
So, now we know that we need 11.25 cups of sugar to make 1 batch of chocolate chip.
Therefore, we know we need 90 cups of sugar for 8 batches because
11.25 * 8 = 90

Which one best models line l?
ans : A
reason : gradient = 0 and the line does not touch Y axis
i hope this helps :))
The equation of line l if the line is shifted 4 units to the right is x = 4, so option A is correct.
What is line?A simple line in Euclidean geometry. A line, according to Euclid, is the distance between two points and can stretch forever in either direction. While Euclid's initial definition is now regarded as a line segment, such an extension in both directions is now thought of as a line.
Given:
The lines y and l are given in the graph,
The equation of the line y can be written as shown below,
y = x + c
x = c (as the y coordinate of the y-axis is zero)
The equation of the line shifted 4 units to the right can be represented as
y = mx + c
Here, the slope is 1 and the intercept is -4 so,
x = 4
Thus, the line l is x = 4.
