Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
well you know it's a 90° so do you know what Sin(90) is? you should :D
I think this is kinda a trick question too b/c Opp here is also Hyp
so it would like like sin(90) = Opp / Hyp but that's 427/427 for this question. seems kinda confusing why ask it that way.. huh :/
sin(90) = 1

The Golden Gate bridge was built in San Francisco, California, in 1937. Until 1964, it was the longest suspension span in the world. The length of the cable from the top of the tower to where it anchored in the concrete is 2332 m, and the height of each tower is 152 m. Assuming the cable forms a straight line, how far from the base of the tower is the cable anchored?
Answers
EXPLANATION:
I’m assuming this is Reverse Pythagorean Theorem, so the equation would be c^2 - a^2 = b^2, so all you have to do it substitute the variables and solve. The length of the cable is variable c, the height of the tower is variable a, and the length of where is the cable is anchored and the base of the tower is variable b. That might not make any sense but feel free to ask any questions. :)

The school that Shawna goes to is selling tickets to a spring musical. On the first day of ticke sales the school sold 7 adult tickets and 7 student tickets for a total of $91. The school took ir $170 on the second day by selling 14 adult tickets and 12 student tickets. Find the price of an adult ticket and the price of a student ticket.
Answers
Answer:
price of an adult ticket = a = $7
price of a student ticket = s = $6
Step-by-step explanation:
price of an adult ticket = a
price of a student ticket = s
7a + 7s = 91 (1)
14a + 12s = 170 (2)
Multiply (1) by 2
7a + 7s = 91 (1) × 2
14a + 14s = 182 (3)
14a + 12s = 170 (2)
Subtract (2) from (3) to eliminate x
14s - 12s = 182 - 170
2s = 12
s = 12/2
s = 6
Substitute s = 6 into (1)
7a + 7s = 91 (1)
7a + 7(6) = 91
7a + 42 = 91
7a = 91 - 42
7a = 49
a = 49/7
a = 7
price of an adult ticket = a = $7
price of a student ticket = s = $6

Hi there!

1) Find the perimeter
[tex]P=5l[/tex] where l is the side length
Plug in the side length 7.6 cm
[tex]P=5(7.6)\\P=38[/tex]
Therefore, the perimeter of the pentagon is 38 cm.
2) Find the area
[tex]A=\frac{1}{2} Pa[/tex]
Plug in the perimeter (38) and the apothem (5.2)
[tex]A=\frac{1}{2} (38)(5.2)\\A=\frac{1}{2} (38)(5.2)\\A=\frac{1}{2} (197.6)\\A=98.8[/tex]
Therefore, the area of the pentagon is 98.8 cm².

Solve the following quadratic by
completing the square.
y = x2 – 8x + 5
Answers
Answer:
x = 4 ± √11
Step-by-step explanation:
hello :
x²-8x+5= x² -2(4 )(x)+5
x²-8x+5= x² -2(4 )(x)+5 = ( x² -2(4 )(x) +4²) -4²+5
= (x-4)²-11 .....( completing the square )
x²-8x+5= 0 means : (x-4)²-11 = 0
(x-4)²=11 but : 11 = (√11)² = ( - √11)²
x-4 =√11 or x-4 = -√11
x = 4 ± √11
Answer:
x = 4 ± [tex]\sqrt{11}[/tex]
Step-by-step explanation:
To solve the equation let y = 0 , that is
x² - 8x + 5 = 0 ( subtract 5 from both sides )
x² - 8x = - 5
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = - 5 + 16
(x - 4)² = 11 ( take the square root of both sides )
x - 4 = ± [tex]\sqrt{11}[/tex] ( add 4 to both sides )
x = 4 ± [tex]\sqrt{11}[/tex]

the value of y varies directly x, and when x = 5y=25. What is the value of y when x is 20?
Pls ASAP T.T
Answers
Answer: i don't think its possible for 20 to equal 5y and 25 the reason why is because for 5y to equal 20 y=4 that may be the answer but im not completely sure if it was supposed to be 20=x and 5y+25=x
Step-by-step explanation:
if it was supposed to be 20=x and 5y+25=x the new equation would be 5y+25= 20 you then divide 5 from both sides. and get y=4
but if the equation was supposed to be x+5y=25 and x equals 20 then y would equal 1

Answers
Answer:
C
Step-by-step explanation:
Between nine and ten years after opening the account, the balance grew by $5,000.
Between nine and ten years after opening the account, the balance grew by $5,000. The correct answer would be an option (C)
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The function g(x) represents the amount of money in a savings account x years after it is opened.
The statement g(10) - g(9) = $5,000 represents the difference in the balance between 9 and 10 years after opening the account, and since the difference is positive, it means that the balance grew by $5,000.
Hence, the correct answer would be an option (C)

45 percent of 125 is 56.25 so you subtract that from 125 and get 68.75 and then you do 5.2 percent of 68.75 and get 3.575 which rounds to 3.58 and you add that to 68.75 and get 72.33
