prove that 1-cosA/sinA=cosecA-cotA
Answer:
See the proof below
Step-by-step explanation:
prove that 1-cosA/sinA=cosecA-cotA
Starting from RHS
cosecA-cotA
From trig identty
cosec theta = 1/sintheta and cot theta = cos theta/sin theta
Hence;
cosecA-cotA
= 1/sinA - cosA/sinA
FInd the LCM
= 1-cosA/sinA (LHS)
For each of the following, indicate whether or not a paired analysis would be appropriate.
a. A school cafeteria offers a vegetarian and a nonvegetarian option for lunch every day. For a period of two weeks, you record how many calories are in the vegetarian option and how many calories are in the nonvegetarian option. Your goal is to see if vegetarian options tend to differ with regard to average number calories from nonvegetarian options.
b. A farmer investigates whether talking to cows by name leads to producing more milk. He randomly selects 30 of his cows and randomly assigns 15 to talk to by name and the other 15 not to.
Answer: a. a paired analysis is appropriate
b. a paired analysis is not appropriate
Step-by-step explanation:
The paired analysis sometimes is refered to as a statistical procedure which is used to know if the mean difference that exist between two observations is zero or not. It should be noted that in a paired analysis, each subject is measured twice, and this beings about the pairs of observations.
a. Here, the paired analysis is appropriate due to the fact that similar measurement which are the calories are taken for several days for both the vegetarian and the non vegetarian such are two pairs of sample.
b) In this case, the paired analysis is not appropriate. Here, the pairs of samples don't undergo identical treatment.

Solve for z 7-√3z+2=4 What is the root? If there is no root, choose none. z = 7/3 z = 11/3 none
Answer:
Desmos is Function Calculator is a great tool for this, the correct answer is z= 7/3
7/3= 2.333~ and so √(3*2.333~) + 2= 2.9999999833333~
Now 7- 2.9999999833333~= 4.0000000166667~ but I don't know the true infinate sign for this so thats why my numbers look a little weird, just plug (7/3) in for z and you will get 4, trust me

The theater sells two types of tickets: adult tickets for $11 and child tickets for $9.
Last night the theater sold 262 tickets for a total of $2482. How many adult tickets did the theater sell last night?
Answer:
a=62
Step-by-step explanation:
11a + 9c=2482 equation 1
a + c = 262 equation 2
a=262-c isolate value of a in equation
11(262-c) + 9c = 2482 substitute value of a (262-c) into equation 2
2882-11c + 9c= 2482 solve
-2c=-400
c=200
a+c=262
a+200=262
a=62
Check answer:
11a + 9c=2482
11(62)+9(200)=2482
682+1800=2482
2482=2482

In the figure shown above, all the corners form right angles. What is the area of the figure in square units?
9514 1404 393
Answer:
70 square units
Step-by-step explanation:
The overall outline is 15 units wide and 8 units high, for an area of ...
A = WH
A = (15 units)(8 units) = 120 units²
__
The white space taken out of that overall area is 5 units high and 15-4-1 = 10 units wide. The area of the white space is ...
A = (5 units)(10 units) = 50 units²
__
The shaded area is the difference between the overall area and the white space taken out:
shaded = 120 units² -50 units² = 70 units²

Answer:
The solution is 4 >/= -21
4 is greater than or equal to negative 21
Step-by-step explanation:
7x + 4 >/= 7(x - 3)
We'll start by distributing the y7 to the items in parentheses
7x + 4 >/= 7x - 21
Subtract 7x from both sides
4 >/= -21

Answer:
y = x + 3
Step-by-step explanation:
Equation of the line can be written as y = mx + b (slope-intercept form)
Let's find the slope (m) and the y-intercept (b)
Slope (m) = change in y/change in x
Using two points on the line, (0, 3) and (1, 4),
Slope (m) = (4 - 3)/(1 - 0) = 1/1
m = 1
y-intercept (b) = 3 (the coordinate of the point where the y-axis is intercepted by ye line)
To write the equation, substitute m = 1 and b = 3 into y = mx + b
y = 1(x) + 3
y = x + 3
how do i solve systems by substitution

A survey was conducted to compare the mean cost of a meal at fast food restaurants in two different cities.
City n x s
A 26 $4.05 $0.55
B 32 $5.15 $0.85
Assume that the population variances of both groups are different. Test if there is sufficient evidence that the mean costs of a meal at fast food restaurants in two different cities are different. Conduct the hypothesis testing (optional) in paper.
Answer:
We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.
Step-by-step explanation:
Given :
City n x s
A 26 $4.05 $0.55
B 32 $5.15 $0.85
H0 : μ1 - μ2 = 0
H0 : μ1 - μ2 ≠ 0
n1 = 26 ; x1 = 4.05 ; s1 = 0.55
n2 = 32 ; x2 = 5.15 ; s2 = 0.85
Tstatistic :
(x1 - x2) / √(s1²/n1 + s2²/n2)
(4.05 - 5.15) / √(0.55²/26 + 0.85²/32)
-1.1 / 0.1849668
= - 5.947
Using the smaller n;
df = n - 1 ; 26 - 1 = 25
Pvalue = (-5.947, 24)
Pvalue = 0.000001
Since Pvalue < α ; We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.

Mikos family drove at a constant speed as they left home and traveled to the restaurant where they stopped for lunch. Does the relationship between hours elapsed x and distance traveled y represent a proportional relationship? Explain why or why not
(100 points and brainliest)
Answer:
yes,
distance = time * speed
the more hours you spend in the road, the longer distance you took
Step-by-step explanation:
Answer:
Yes, the relationship between hours elapsed x and distance traveled y represent a proportional relationship.
Step-by-step explanation:
This is because he continuously stayed at a constant speed and didn't change. Once you stay at a constant speed then it will always be a proportional relationship.

41. How would the graph of the function
y=x2- 3 be affected if the function were
changed to y=x2 + 2?
A. The graph would shift 2 units up.
B. The graph would shift 5 units up.
C. The graph would shift 5 units down.
D. The graph would shift 1 unit up,
Answer:
B. The graph would shift 5 units up.
Step-by-step explanation:
Before the change:
Before the change, the function was given by:
[tex]y = x^2 - 3[/tex]
After the change:
After the change, the function was given by:
[tex]y = x^2 + 2[/tex]
Considering the function as it was before the change, it can also be written as:
[tex]y = x^2 - 3 + 5[/tex]
Which means that 5 was added to the function, and when a number n is added to a function, there function is shifted n units up. So the correct answer to this problem is given by option B.
the area of a sector is a secotor = n/360 degrees pie r 2^ what does the term n/360 degrees
Answer:
4th option
Step-by-step explanation:
[tex]\frac{n}{360}[/tex] represents the fraction of the circle occupied by the sector , that is
The ratio of degrees in the sector's central angle to the total number of degrees in the circle
Option 4 is correct. The ratio of degrees in the sector's central angle to the total number of degrees in the circle.
What is the fraction?Fraction is defined as the number of composition constitute the Whole.
area of a sector is a secotor = n/360 degrees pie r^2
n =number of fraction at which the circle is divided
mean n = in degrees x number of angles.
and the ratio n/360 degrees
describes the number of partition to the circle.
Thus, the ratio n/360 degrees defines The ratio of degrees in the sector's central angle to the total number of degrees in the circle.
