I. You and three friends go to the town carnival. You have a coupon for $20 off that will
save your group money! If the total bill to get into the carnival was $100, how much does one
regular price ticket cost?
Write the equation and solve:
Answer:
The regular cost of each ticket is $30
Step-by-step explanation:
Hi,
You and three friends means there was a total of 4 people. Your equation is...
4x - 20 = 100
Remember to add the -20 since there was a coupon that saved you $20.
Now solve...
4x - 20 = 100
+ 20 on both sides
4x = 120
Divide by 4 on both sides
x = 30
The regular cost of each ticket is $30
Hope this helps :)
Answer:
e it's really first question re want to make this

Assume that theta is a positive acute angle.
Given: sin theta=40/41
Find: cos2theta
SHOW YOUR WORK. First correct answer gets Brainliest.
By utilizing trigonometric identities,we got cos 2θ = -1519/1681.
Given that sin θ = 40/41 and θ is a positive acute angle, we can find cos θ using the Pythagorean identity sin²θ + cos²θ = 1. Rearranging the equation, we have cos²θ = 1 - sin²θ.
Substituting the given value, we get cos²θ = 1 - (40/41)² = 1 - 1600/1681 = 81/1681.
Now, we can find cos 2θ using the double-angle identity cos 2θ = cos²θ - sin²θ.
Substituting the known values, we have
cos 2θ = (81/1681) - (40/41)² = 81/1681 - 1600/1681 = -1519/1681.
Therefore, cos 2θ = -1519/1681.

Mr. Gow needs to build a wheelchair access ramp for the school's auditorium. The ramp must rise a total of 3 feet to get from the ground to the entrance of the building. In order to follow the state building code, the angle formed by the ramp and the ground cannot exceed 4.75°.
Mr. Gow plans from the planning department that call for the ramp to start 25 feet away from the building code?
a. Draw an appropiate diagram. Add all the measurements you can. What does Mr. Gow need to find?
b. According to the plan in part (a), what angle will the ramp make with the ground? Will the ramp be to code?
c. If Mr. Gow builds the ramp exactly to code, how long will the ramp be? In other words, at least how far from the building must the ramp start in order to∞ meet the building code? Show all work.
(NOT A MULTIPLE CHOICE)
9514 1404 393
Answer:
a. see below for diagram. Angle for the length; length for the angle
b. 6.84°; not to code
c. 36.1 ft
Step-by-step explanation:
a. The diagram is shown below. Mr. Gow needs to find the angle it makes in order to determine if it is up to code. Alternatively, Mr. Gow needs to find the required length for a ramp that meets code.
__
b. The angle the ramp makes can be found using the tangent relation.
Tan = Opposite/Adjacent
tan(angle) = 3/25
angle = arctan(3/25) ≈ 6.84°
The ramp will make a 6.84° angle with the ground. It will not meet code.
__
c. We can find the distance from the building where the ramp must start using the same trig relation.
tan(4.75°) = (3 ft)/(distance)
distance = (3 ft)/tan(4.75°) ≈ 36.1 ft
The ramp must start 36.1 feet from the building to exactly meet code.

Consider the function f(x)=-3x2+12x-5. What is the location of the vertex? Write your answer as an ordered pair.
Answer:
The (x,y) point of the vertex is usually labelled as:
Vertex = (h, k)
h = -b / 2a
k = ah^2 + bh + c
f(x) = -3x^2 + 12x -5
a = -3 b=12 c=-5
h = -12 / -6 therefore h = 2
k = -3*2^2 + 12*2 -5
k = -12 + 24 -5 therefore k = 7
Vertex (2, 7)

[tex](x_2,y_2) = (3,1)[/tex]
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

What are the zeros of the polynomial function f(x) = x3 - 2x2 - 24x? (1 point)
1) -6, 0, 4
2) 6, 0, -4
3) -6, 0, -4
4) 6,0, 4
f(x) = x³ - 2x² - 24x
x³ - 2x² - 24x = 0
x(x² - 2x - 24) = 0
x = 0
x² - 2x - 24 = 0
a = 1, b = -2, c = -24
Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100
x = (-(-2) - 10)/(2 * 1) = -8/2 = -4
x = (-(-2) + 10)/(2 * 1) = 12/2 = 6
