Answer:
Step-by-step explanation:
1, sec theta * sin theta = 1/cos * sin = sin/cos =tan theta
2. cosec theta * cos theta = 1/ sin * cos = cos/sin = cot theta
3, tan theta * cosec theta =sin/cos * 1/sin = 1/cos
4, cot theta * sec theta = cos /sin * 1/cos= 1/sin
5, 1 - cos^2 theta = sin ^2 theta
6, sec^2 theta - 1 =tan ^2 theta
7 , cosec^2 theta - cot^2 theta = 1
8, 1 - sin^2 theta = cos^2

Drag answer here
x>-2 x<5. x>13. x<-2. x>5
Answer:
1. x > 13
2. x < -2
3. x < 5
Step-by-step explanation:
2x - 3 > 23
→Add 3 to both sides:
2x > 26
→Divide both sides by 2:
x > 13
2x - 3 > 3x - 1
→Subtract 2x from both sides:
-3 > x - 1
→Add 1 to both sides:
-2 > x
5x - 4 < 21
→Add 4 to both sides:
5x < 25
→Divide both sides by 5:
x < 5

Answer:
8 units = L
Step-by-step explanation:
The area of a rectangle is the product of length and width.
A = L*W
If A = 56 units^2 and W = 7 units, then L = (56 units^2) / (7 units) = 8 units = L
Juan bought a MP3 player for $45 after a 15% discount.
Answer:
Find the exact value using trigonometric identities. a MP3, 45, 0.15
Step-by-step explanation:
so your answer is $45.15 that is how much it was before the discount :)
Answer:
$8.25
Step-by-step explanation:
discount = x
original price = $45.00
discount% = 15%
x/45 = 15/100
x · 100 = 15 · 45
100x = 675
100x/100 = 675/100
x = 6.75
Sale price = 15 - 6.75 = 8.25

How long the altitude of an equilateral triangle with side length 10cm
Equilateral triangles have 3 sides of the same length, so if you split it down the middle, you will end up with one side length of 10cm and another with 5cm. Pythagorus can be used to find the missing side length, because the line of symmetry creates a right angle.
a^2 + b^2 = c^2
5^2 + b^2 = 10^2 (substitute given values in, remember the longest side, or the side opposite the right angle is c)
25 + b^2 = 100 (simplify)
b^2 = 75
b = 8.6603
Check answer
5^2 + 8.6603^2 = 10^2
25 + 75 = 100

Answer:
34.44
Step-by-step explanation:
The distance formula can help you find the lengths of the diagonal sides.
d = √((x2 -x1)^2 +(y2 -y1)^2)
DO = √((6 -0)^2 +(0 -7)^2) = √(36 +49) = √85
OG = √((3 -6)^2 +(-4 -0)^2) = √(9 +16) = 5
The length of NG is 3 -(-3) = 6.
The perimeter is the sum of the side lengths:
P = DI +IN +NG +GO +OD = √85 +5 +6 +5 +√85 = 16 +2√85
P ≈ 34.43909 ≈ 34.44 . . . units

An expression is given: x(-1.8-6y) Use the distributive property to expand the expression.
Answer:
-1.8x-6xy
Step-by-step explanation:
The distributive property is one of the properties of real numbers
Mathematically, we can have it expressed as follows;
a •(b+ c) = a•b + a•c
Thus, applying this to the problem at hand, we have;
x(-1.8-6y) = x •(-1.8) - x•(6y)
Opening the brackets we have;
-1.8x-6xy

Solve the system by substitution.
9y = x
- 4x + y = –35
Answer: The answer is 7x.
Step-by-step explanation:
Answer:
The answer is x=9 and y=1
Step-by-step explanation:
First, you have to substitute x from -4x to 9y which is -4(9y).
That would equal -36y.
Then the second equation would look like this:
-36y + y = -35
Then simplify. If you add -36y and y, it would equal -35y.
-35y = -35
Divide -35 on each side.
y = 1
To find the x value, you have to plug 1 into the first equation. (It doesn't matter which equation you plug into).
So if you plug it into the first equation it would look like this:
9(1) = x
9 = x
If a right triangle has a hypotenuse of 13 inches and a leg of 5 inches, how could you use the Pythagorean Theorem to find the missing side? What is the length of the missing side? Show your work.
Answer:
The length of the missing side is 12.
Step-by-step explanation:
When you solve this, you do 5^2 + b^2 = 13^2
and solve for b. 25 + b^2 = 169
169 - 25 = 144
[tex]\sqrt{144[/tex] = 12
When you check your work, 5^2 + 12^2 = 13^2
25 + 144 = 169
If you have the right triangle, then you can label the longer side with 13, and label the leg 5. the you solve for the other leg. That's how Pythagorean Theorem is used in this context.
I hope this helped. I'm not the best at explaining math.

Answer:
D
Step-by-step explanation:
Proportional relationships go through the origin on the graph so we can eliminate A and B. Also the x and y coordinates have the same ratio so the answer is D because 2:3 = 4:6 = 8:12 = 12:18.

Answer:
economy class = 260
business class = 100.
Step-by-step explanation:
for every 13 economy seats, there are 5 business class seats
EC = 13
BC = 5
ADD to get total = 18
divide 360 by 18 to get the number of groups created.
you get 20.
multiply 20 by each class seats
13 by 20 = 260
5 by 20 = 100
you can confirm by adding the seats to see if you will get 360.
x^2+1/x^2=18 find x-1/x
Notice that
[tex]\left(x-\dfrac1x\right)^2=x^2-2+\dfrac1{x^2}=18-2=16[/tex]
which tells us

I need a real world example of a relation that is a function.
Answer:
Domain: the set of “Pregant Sheep”
Range: the set of “Lambs Born”
Exaplain why your Relation is a Function.
“The reason it‘s a function is the fact that there is two parents (if you include the dad) and you can have one to three lambs born.
Step-by-step explanation:
We want to write a real-world example of a relation that is a function.
First, let's describe what a function is.
A function is a relationship that maps elements from a set, the domain, into elements from another set, the range.
Such that each element in the domain can be mapped into only one element in the range.
So for example, if for a given item we have 2 different prices, like:
f( bar of soap) = $10f(bar of soap) = $5.this is not a function, because the input "bar of soap" is being mapped into two different elements of the range.
Now that we know what a function is, we can create a real-world example.
Let's create a really simple one, let's say that in your local store they sell each bar of soap for $2.
Then, if you buy x of these, the cost will be x times $2, or:
$2*x
Then we can create a function, the cost function, that models the cost of buying x bars of soap at your local store, it is:
c(x) = $2*x
This is a function that models a "real-world" problem.

The Air conditioner unit in the classroom uses 120 volts. it requires 2000 watts of usage on the average, and it stays on for 8 hours every day. Find out the Amps, Watt hrs/Day, Watts hrs/yr, Kilowatt Hrs/Yr and cost/Yr if the cost of elelctricity per kilowatt is $0.25
Step-by-step explanation:
P = IV
2000 W = I (120 V)
I = 16.7 A
P = E/t
P = (2000 W × 8 hr) / (1 day)
P = 16,000 W·hr/day
P = 16000 W·hr/day × (365 day / yr)
P = 5,840,000 W·hr/yr
P = 5,840,000 W·hr/yr × (1 kW / 1000 W)
P = 5840 kW·hr/yr
C = 5840 kW·hr/yr × (0.25 $/kW/hr)
C = $1460/yr
