Answer:
1
Step-by-step explanation:
We will use x instead of theta
● cos^2 x *(1+tan^2x)
We khow that: 1+ tan^2 x = 1/cos^2 x
Replace 1+tan^2 x by the new expression
● cos^2 x (1/cos^2 x)
● cos^2x/ cos^2 x

Arnold made the following grades on his quizzes and assignments: 80, 92, 88, 90, 75, 38, 92, 95 2. Arnold wants to present his scores as advantageously as possible. Should he use the mean or the median of this data set? What other strategies could he employ to yield a more favorable measure of center?
Answer:
Step-by-step explanation:
If he were to find the mean then he would need to add all the numbers up and divide by the number of numbers. The answer of this would 69.1
If you find the median you would need to put the numbers in order,
2, 38, 75, 80, 88, 90, 92, 92, 95, then find the middle which would be 88.
So the better option would be finding the median. I think that this would be the best way to get the the most favorable measure of center.
I hope this helps.

Sarah has $20 saved. She gets $10 per week for her allowance, and she saves her allowance for the next 3 weeks. At the end of the week, she gets $150 in birthday money. How much money will she have after the 3 weeks? Which of the following sets of equations represents this problem?
Answer:
$200
Step-by-step explanation:
We know that she already has $20. And we know that every week, for three weeks she gets $10.
20+3(10)+150=m
We add all of this up, and we find that at the end of 3 weeks Sarah has $200 saved.

Owen made 60% of the shots he attempted during his hockey practice. He made 18 shots. How many shots did Owen attempt during his hockey practice?
Answer:
11 shots
Step-by-step explanation:
60% of 18 = 10.810.8 rounded = 11Why we did this:
Owen made 60% of the shots he made, and he made 18 shots in total. Therefore, we would take 60% of 18.The answer we get is 10.8, but we can't have a part of a shot. That wouldn't make sense. Therefore, we have to round up to 11 shots.So therefore, Owen made 11 of 18 shots he attempted.
Owen attempted 11 shots during the hockey practice.
Number of shots attempted by Owen = 18
Percentage of shots made = 60%
Then, the number of shots made will be calculated as:
= Percentage of shots made × Number of shots attempted
= 60% × 18
= 60/100 × 18
= 0.6 × 18
= 10.8 shots
= 11 shots approximately
In conclusion, Owen made 11 shots

Briefly explain your knowledge of sine, cosine, and tangent.
Answer:
Sine, Cosine and Tangent are main functions used in Trigonometry .
They are based on a Right-Angled Triangle.
It helps to give a name to each side of a right triangle:
"Opposite" ; side opposite to the angle θ
"Adjacent"; side adjacent (next to) to the angle θ,
"Hypotenuse" ; the longest side
Step-by-step explanation:
Sine, Cosine and Tangent (are often shortened as sin, cos and tan)
They are used in calculation by;
[tex]Sin \alpha = \frac{Opposite}{Hypotenuse}\\ \\Cos \alpha = \frac{Adjacent}{Hypotenuse}\\ \\Tan \alpha = \frac{Opposite}{Adjacent}[/tex]

Answer:
Step-by-step explanation:
Let the other number = x
x + 40 = 73
Subtract 40 from both sides
x + 40 - 40 = 73 - 40
x = 33

33
Step-by-step explanation:
Let the another number = x
Sum of two numbers = 73
A.T.Q
x + 40 = 73
x = 73-40
x = 33

What is the measure of \angle x∠xangle, x?
Angles are not necessarily drawn to scale.
Answer:
74 degrees
Step-by-step explanation:
You can see this is a supplementary angle, which means that it is a straight line with a line sticking out. This means the two angles add up to 180 degrees, so 180 - 106 = 74, which is your answer.
Answer:
x = 74°
Step-by-step explanation:
x + 106 = 180 {linear pair}
Subtract 106 from both sides
x = 180 - 106
x = 74°

In a survey of 119 students, it was found that 16 drink neither coke nor Pepsi 69 drinks coke and39 drink pepsi
How many students drink Coke only?
How many students drink Pepsi only?
Show the above information in a Venn diagram.
Answer:
64 students drink coke only
34 students drink pepsi only
Step-by-step explanation:
Here, we want to know the number of students that drink coke only and number of students that drink pepsi only.
Let the number of students that drink both be x
Mathematically,
n(μ) = 119 where μ represents the universal set
n(P) = 39
n(C) = 69
n(C n P) = x
n(C n P)’ = 16
n(P) only = 39 - x
n( C) only = 69 - x
Mathematically;
119 = (69-x) + (39-x) + x + 16
119 = 69 + 39 + 16 -2x + x
119 = 124 - x
x = 124 - 119
x = 5
So the number of students drinking pepsi only = 39 -5 = 34
The number of students drinking coke only = 69-5 = 64
