Equation:
m<DGF = m<DGE + m<EGF
Given:
m<DGF = 12y - 5
m<DGE = 5y + 6
m<EGF = 24
Work:
m<DGF = m<DGE + m<EGF
12y - 5 = 5y + 6 + 24
12y - 5 = 5y + 30
12y - 5y = 30 + 5
7y = 35
y = 5

no links please
Answers
Answer:
$390
Step-by-step explanation:
262.50/35 = 7.5 per hour during normal week
Saturdays 11.25 per hour
Sundays 15 per hour
6x11.25 = 67.5
4x15=60
262.50 +67.5 +60 = 390

A Ferris wheel has a diameter of 380 feet and the center of the wheel is 195 feet above the ground. The wheel makes a complete turn every 4 minutes. Write a cosine function to express the height h (in feet) of a passenger on the wheel as a function of time t (in minutes), given that the passenger is at the lowest point on the wheel when t
Answers
Answer:
y = -190 cos(π t / 120) + 195
Step-by-step explanation:
General form of a sinusoidal function: y = A cos(Bt - C) + D
Now generally a cosine function starts at the maximum value, so to start at the minimum value, flip the cosine function by making it negative.
A is the amplitude of the curve and will be the radius of the ferris wheel. Therefore, A = 380 / 2 = 190 feet.
2π / B is the period of the curve and will be the time to complete one full rotation. The time to complete one full rotation is given as 4 minutes. Convert this into seconds to get period = 4 minutes * (60 seconds / minute) = 240 seconds. Therefore, B = 2π / period = 2π / 240 seconds = π / 120.
C/B is the phase shift, or horizontal shift of the graph. Since the negative cosine function already starts at the minimum value, there is no phase shift so C/B = 0, meaning C = 0.
D is the vertical shift and will be the height of the center of the ferris wheel. Therefore, D = 195 feet.
Your final function will be:
y = -190 cos(π t / 120) + 195

Explain why 4x+1 is equal to 2x+12
Answers
4x+1=2x+12
4x+1-2x=12-1
2x=11
x= 11/2
simplified version is x= 5.5
4x+1=2x+12
So you have to move x to the same side means you have to switch the side for 1 and 2x (if you you are changing the side the value will be negative when it is switched but if the value is positive it will be negative when you switch the side)
4x-2x=-1+12
Now you have to simplify it.
2x=11
Now this is the last step. You need to change the value “2” to the another side. Since 2 is multiplying with x so when you switch the side it will divide with 11.
So, x=11/-2
It’s negative 2 because it switched the side.
Final answer is: x= -5.5
Now find the value for y.
Since you have found the value of x you can calculate the value of y: y=4(5.5)+1=23
y=2(5.5)+12=23
Now as you can see here that the value of y for both equations is the same so that’s why 4x+1 is equal to 2x+12

Answers
Answer:
Evelyn's dance class on Saturday starts at 11:05 A.M.
Step-by-step explanation:
I know this because if her class takes an hour and 40 minutes you would subtract the hour and 40 minutes from 12:45 so you could do 12 - 1 which equals 11. Then you would do 45 - 40 which equals 5. And last you would put the new times together so it would be, 11:05. Her dance class starts at 11:05 A.M.
Which graph represents equation (x-4)^2+(y+2)=16
F
H
G
I
Answers
Why is this? Recall that (x-h)^2+(y-k)^2 = r^2 is the general template of a circle. The center being (h,k) and the radius is r.
For the equation (x-4)^2+(y+2)^2 = 16, we have a center of (4,-2) and radius 4. Note that 4^2 = 16.
The graph of choice G shows these properties so that's why it's the answer. Keep in mind that each tickmark represents 2 units. Choice I is close since the center is correct but the radius is too small.
