Answer:

y = 5cos(πx/4) +11

Step-by-step explanation:

The radius is 5 ft, so that will be the multiplier of the trig function.

The car starts at the top of the wheel, so the appropriate trig function is cosine, which is 1 (its maximum value) when its argument is zero.

The period is 8 seconds, so the argument of the cosine function will be 2π(x/8) = πx/4. This changes by 2π when x changes by 8.

The centerline of the wheel is the sum of the minimum and the radius, so is 6+5 = 11 ft. This is the offset of the scaled cosine function.

Putting that all together, you get

... y = 5cos(π/4x) + 11

_____

The answer selections don't seem to consistently identify the argument of the trig function properly. We assume that π/4(x) means (πx/4), where this product is the argument of the trig function.

Answer:


Step-by-step explanation:

You have to start by making a small chart of what  is happening at what time.

x    0        4        8

y    16       6       16

Essentially this is a cosine function.

Now you need to fill in some of the details. The key is what is happening at x = 4 seconds? At that time, you must add a minus amount in the cosine function to the amplitude to get 6. The only way to do that is if you have

y = 5* cos( (x/4)*pi) + 11

y = 5*cos( (4/4)*pi) + 11

y = 5 * cos(pi) + 11

y = 5 * (-1) + 11

y = -5 + 11 = 6

==================

x = 0

y = 5* cos( (pi/4)*0 ) + 11

y = 5 * cos(0) + 11

y = 5 (1) + 11

y = 16

===================

x = 8 seconds

y = 5*cos(8/4)*pi) + 11

y = 5*cos(2*pi) + 11

y = 5 * (1) + 11

y = 16

==================

The question is where did the 11 come from?

The Ferris wheel has a diameter of 10 feet and a radius of 5

The high and low points are 16 and 6.

The center of the Ferris wheel is between 16 and 6. Between in this case means average.

(16 + 6)/2 = 22/2 = 11

Shanika makes 2,800 milliliter so of chicken soup for a dinner party.she needs 3.5 liters. how many more milliliter so does shan
WINSTONCH [101]
1L=1000mL
2800 mL=2.8L
If she needs 3.5 L, she currently has 2.8L,
so 3.5-2.8=0.7 L more or .7x1000=700 more mL

Jerome will also order t-shirt for the volunteers he will order both adults and child size t shirt
RideAnS [48]

a >= 200

5 a + 2.5 c <=1500

Step-by-step explanation:

Step 1 :

Let c be the number of child t shirt and a be the number of adult t-shirts

Given the cost of adult t-shirt is $5 and the cost of child t-shirt is $2.50

Step 2 :

Inequality 1

Given that Jerome needs at least 200 adult t-shirts .

So the minimum quantity of adult t-shirts should be 200

Hence we have a >= 200

Step 3 :

Inequality 2

Given that the total cost should be less that $1500

We have,

5 a + 2.5 c <=1500

Find the area of the following shape, given its curves are made from parts of circles with diameters indicated on the diagram.
Alexxandr [17]

Answer:

222.51 (when rounded)

Step-by-step explanation:

Pi x r squared is the formula to find the area of a circle

153.94 + 12.57 + 56

= 222.51

You basically find the area of each circle by find their diameters. So half of the length shown on each circle.
