A Ferris wheel with a radius of 19m rotates once every 56 seconds. The top of the
wheel is 42.5m above the ground.
Determine a sine and cosine equation of the function that gives the rider's height
above the ground in metres, as a function of time, in seconds, with the rider starting
at the bottom.
Answers
Answer:
(First of all its 20 points not 40 but any ways) A ferris wheel has a raidus of 20 m. Passengers get on halfway up on the right side. The direction of rotation is counter clockwise. The bottom of the ferris wheel is 2 m above ground. It rotates every 36 seconds. Determine height above the ground after 15 seconds algebraically. Determine seconds to the nearest tenth when height is 38 m above the ground algebraically.
**
let t=seconds after wheel starts to rotate.
let h=meters above ground after wheel starts to rotate
..
The formula I got: h(t)=20sin(πt/18)+22
This is close to the formula you got, except I left the negative sign out since passengers start to rise after the wheel starts going counter-clockwise.
..
After 15 seconds:
h=20sin(15π/18)+22
=20sin(5π/6)+22
=20*(1/2)+22
=32 m
..
When h=38 m
38=20sin(πt/18)+22
38-22=20sin(πt/18)
20sin(πt/18)=16
sin(πt/18)=16/20=4/5=.8
arcsin(.8)=0.927
πt/18=0.927 (radians)
t=(.927*18)/π≈5.31
..
height above the ground after 15 seconds≈38 m
seconds elapsed when height is 38 m above ground≈5.3 seconds

Answer:
y = 1/2x^2 +x -15/2
Step-by-step explanation:
The vertex is the point where the graph reaches is extreme: (-1, -8). The y-intercept is (0, -7.5). The x-intercepts are (-5, 0) and (3, 0).
When the quadratic is written in the form ...
y = x^2 +bx +c
the value of b is the opposite of the sum of the x-intercepts. The value of c is their product. These facts would give ...
y = x^2 -(-5 +3)x +(-5)(3) = x^2 +2x -15
The constant in this equation is -15, which is the value y has when x=0. Our actual y-intercept is half that, so the graph we see is this equation scaled by a factor of 1/2:
y = 1/2x^2 +x -15/2
_____
Alternate solution
You can start with the vertex form.
y = a(x -h)^2 +k . . . . . . . vertical scale factor 'a' and vertex (h, k)
On the graph, the vertical scale factor is the vertical difference between the low point (vertex) and the point that is 1 unit right or left. Here, that is ...
-7.5 - (-8) = 0.5 = a
We've already said the vertex is (h, k) = (-1, -8), so the vertex form equation is ...
y = 0.5(x +1)^2 -8
We know the square of a binomial is (a+b)^2 = a^2 +2ab +b^2, so we have ...
y = 0.5(x^2 +2x +1) -8
y = 0.5x^2 +x +0.5 -8 . . . . . eliminate parentheses
y = 0.5x^2 +x -7.5
The expression 13.26d + 9.20c can be used to find the total cost of d pounds of almonds and c pounds of cashews. How much does it cost to buy \ pounds of almonds and \ pounds of cashews?
Answers
Answer:
The expression shows the price of one pound of almonds and one pound of cashews.
The number that we are to multiply to find the total cost of almonds is the cost of 1 pound of almonds which is $13.26 and the same goes for cashews, $9.20.
Now assuming we are to find the cost of 5 pounds of Almonds and 4 pounds of cashews, the total cost would be:
= (13.26 * 5) + (9.20 * 4)
= 66.3 + 36.8
= $103.10

Jesse has 4 pairs of black socks, 5 pairs of red socks, and 15 pairs of white socks in a dresser drawer. If he reaches in his drawer without looking, what is the probability that he will choose a pair of white socks?
62.5%
50%
70%
60%
Answers
Answer:
62.5%
Step-by-step explanation:
You need to add all the socks to get the total amount of socks:
4 Black Pairs + 5 Red Pairs + 15 White Pair = 24 Total Pairs.
Next you need to find the probability of pulling a white pair so you divide the amount of white pairs to the total pairs of socks.
15 / 24 = 0.625 %
0.625 x 100 = 62.5%

Write this expression in the fewest number of terms: x+3y+2x+10+2y+12
Answers
Answer:
3x+5y+22
Step-by-step explanation:
Answer:
3x + 5y + 22
Step-by-step explanation:
Given expression:- x + 3y + 2x + 10 + 2y + 12
Here, you can add all the 'x' terms together and 'y' terms together.
There is an 'x' and '2x'.
On adding them, you get 2x + x equals 3x.
Then add the 'y' terms
There is a '3y' and a '2y'. On adding them, you get 3y + 2y equals 5y.
Then add the numbers that are left. 12 and 10.
12 + 10 equals 22.
Then take all the values we got after addition:- 3x, 5y and 22.
2x, 5y and 22 cannot be added together. So, the expression in the simplified form would be:-
