Do you know SOHCAHTOA
Sin = opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tangent = opposite/adjacent
#1
We have to find cos(x) = adjacent/hypotenuse
[tex]cos(x) = adj/hyp\\=\frac{24}{26} = \frac{12}{13}[/tex]
#2:
We are given an angle of 30 degrees and an opposite side of 15
We need to find the adjacent side, so we can use Tangent
[tex]tan(30) = \frac{15}{adj}[/tex]
[tex]adj = \frac{15}{tan(30)} = 25.98 = 26[/tex]
#3
We are given an angle and an opposite side and we have to solve for hypotenuse.
We can use sin
[tex]sin(43) = \frac{16}{x} \\x = \frac{16}{sin(43)} = 23.46 = 23.5[/tex]
#4:
We are given two sides, we have to find the angle. We are given an opposite side and an adjacent side, so we can use arctangent ([tex]tan^-1(x)[/tex], but not 1/tan(x))
[tex]tan(x) = \frac{36}{19} \\arctan(36/19) = x\\x = 62.1759[/tex]
#5
We are given an opposite side and the hypotenuse, we can use sin
[tex]sin(x) = \frac{19}{28}\\x = arcsin(19/28) = 42.73 = 43[/tex]

what is the slope and y-intercept of this graph?
Answers
Answer:
Slope is 2
Y-intercept is 7
Step-by-step explanation:
To find the slope we take any two points from the table
and use it in the formula :
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\[/tex]
we take the points (0,7) and (1,9)
now we put these points in the formula and it becomes
[tex]m=\frac{9-7}{1-0}[/tex]
[tex]m=2[/tex]
so our slope which is m is 2 and now for the y-intercept we use the standard equation
[tex]y=mx+c[/tex]
where c is the y-intercept
we use the value of m which is 2 and use any point from the table lets take (0,7)
[tex]y=mx+c\\7=(2)(0)+c\\7=c[/tex]
our y-intercept which is c is 7
so finally our slope is 2 and y-intercept is 7

Step-by-step explanation:
Rise over run
Put into an equation, y1-y2/1-x2
so its
-2-5/3-1 which gives you the answer of -7/2 :)
Answer:
m= 7/-2
Step-by-step explanation:
Use the slope formula.
y2 - y1 = 5 -- 2 = 7
x2 - x1 = 1 - 3 = -2
m = 7/-2
solve the inequality
7y+2<5y+12
Answers
Answer:
y < 5
Step by step:Step 1: Subtract 5y from both sides.
7y+2−5y<5y+12−5y
2y+2<12
Step 2: Subtract 2 from both sides.
2y+2−2<12−2
2y<10
Step 3: Divide both sides by 2.
[tex]\frac{2y}{2}[/tex] < [tex]\frac{10}{2}[/tex]

At a recreation center, it costs $3 per hour to
rent a ping pong table and $12 per hour to rent
a bowling lane. At the same cost as renting a
bowling lane for 2 hours, for how many hours is
it possible to rent a ping pong table?
Answers
This is because if you are renting a bowling lane for 2 hours you would do 12+12 and that’s 24. You would then do 24/3 cause that’s the amount of the cost for 1 hour of the ping pong to rent and that would give you and answer of 8.

If hot and cold water taps are turned on altogether, a bath is filled in three minutes but if the cold tap was only half opened it would take one minute forty eight seconds longer. How long would the hot tap alone take to fill the bath?
Answers
9514 1404 393
Answer:
12 minutes
Step-by-step explanation:
Let c and h represent the filling times for the cold and hot taps, respectively. When the cold tap is 1/2 open, we presume that means the filling time becomes 2c.
In terms of baths per minute, the relationships are ...
1/c + 1/h = 1/3
1/(2c) +1/h = 1/(3 +1.8) . . . . . 1:48 min:sec is 1.8 minutes
Subtracting the first equation from twice the second, we get ...
2(1/(2c) +1/h) -(1/c +1/h) = 2(1/4.8) -(1/3)
1/h = 2/4.8 -1/3 = 1/12
h = 12
It takes the hot tap 12 minutes to fill the tub alone.

Answer:
Jamil buys 6 pens.
Step-by-step explanation:
Jamil buys 4 books and each book costs £5.95. With 5.95+5.95+5.95+5.95 = £23.80. We have the total price for the books. The total cost of books and pens is £37.90 and each pen costs £2.35. If we keep adding £2.35 to our £23.80, we will get £37.90. If we add 23.80+2.35+2.35+2.35+2.35+2.35+2.35 = £37.90. We now have our total amount, and the prices of the amount of books and pens Jamil bought. Jamil bought 6 pens as it equals to £37.90.

Julio says, If you subtract 18 from my number and multiply the difference by −4, the result is −20. What is Julios number?
Answers
Answer:
Julio's number is 40
Step-by-step explanation:
"If you subtract 17 from my number and multiply the difference by negative 4, the result is negative 92.
n= number
(n-17)*(-4) = -92
distribute
-4 *n - 17*(-4) = -92
-4n +68 = -92
subtract 68 from each side
-4n +68-68 = -92 -68
-4n = -160
divide each side by -4
-4n/-4 = -160/-4
n = 40

Answers
Answer:
Step-by-step explanation:
Political parties are organized groups of people with similar ideas or ideology about the function and scope of government, with shared policy goals that work together to elect individuals to political office, to create and implement policies, to further an agenda, and to gain control of the government and the policy-making process. Parties gain control over the government by winning elections with candidates they officially sponsor or nominate for positions in government. Political parties nominate candidates to run many levels of government including the national level, Congress, and the presidency; but, they nominate for state and local levels as well. They also coordinate political campaigns and mobilize voters.
Political parties are points of access/linkage institutions available to the public, though they are not themselves government institutions. Neither interest groups nor political parties are directly mentioned in the U.S. Constitution. Where interest groups often work indirectly to influence our leaders, political parties are organizations that try to directly influence public policy through nominating and officially sponsoring members who seek to win and hold public office. This is a key difference. Interest groups do not officially nominate or nominate candidates for public office, although they may support them politically and even contribute dollars to their campaign.
Parties accomplish this by identifying and aligning sets of issues that are important to voters in the hopes of gaining support during elections. In this respect, parties provide choices to the electorate, something they are doing that is in sharp contrast to their opposition. These positions on these critical issues are often presented in campaign documents or political advertising. During a national presidential campaign, they also frequently reflect the party platform, which is adopted at each party’s presidential nominating convention every four years.
If successful, a party can create a large enough electoral coalition to gain control of the government. Once in power, the party is much more likely to be able to deliver, to its voters, the policy preferences they choose by electing its partisans to the government.Political parties organize political campaigns to win public office for those they nominate.

What is the slope of the line that passes through the points (10, 3) and (2, 3) ?
Answers
(3-3)/(2-10) = 0/-8 = 0
The slope is 0
Work Shown:
Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (3-3)/(2-10)
m = 0/(-8)
m = 0
The slope of any horizontal line is always zero due to the fact all y coordinates on this line are the same. When we pick two points from the line, the same y coordinates subtract to 0. We can have 0 in the numerator, but not in the denominator.
As the slope formula shows, we basically subtract the y coordinates together, and do the same for the x coordinates as well in the same order. Then we divide the differences.

The value of binomial expansion of expression (2x - 3)⁵ is,
⇒ (2x)⁵ – 15(2x)⁴ + 90(2x)³ – 270(2x)² + 405(2x) – 243
We have to given that;
The expression is,
⇒ (2x - 3)⁵
Now, We know that;
The formula of binomial expansion is,
⇒ (x + y)ⁿ = (ⁿ₀) xⁿy⁰ + (ⁿ₁) xⁿ⁻¹y¹ + (ⁿ₂) xⁿ⁻²y² + ...... + yⁿx⁰
Hence, The value of binomial expansion of (2x - 3)⁵ is,
⇒ (2x - 3)⁵
⇒ (2x + (- 3))⁵
⇒ (2x)⁵ – 15(2x)⁴ + 90(2x)³ – 270(2x)² + 405(2x) – 243
Thus, The value of binomial expansion of expression (2x - 3)⁵ is,
⇒ (2x)⁵ – 15(2x)⁴ + 90(2x)³ – 270(2x)² + 405(2x) – 243

Answers
Answer:
16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player
Step-by-step explanation:
Lane is making accessories for the soccer team.
For headbands
He uses 721.54 inches of fabric on headbands for 41 players and 2 coaches.
Hence:
Let the number of inches used for headbands be represented by x
41x + 2x = 721.54
43x = 721.54
x = 721.54/43
x = 16.78 inches
Hence the number of inches used to make head band for 1 player is 16.78 inches
He also uses 361.21 inches of fabric on wristbands for just the players.
We have 41 players hence:
41 players = 361.21 inches
1 player = x
41 × x = 1 × 361.21 inches
x = 361.21 inches/41
x = 8.81 inches
8.81 inches of fabric was used for wristbands for each player.
Hence:
16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player
