The Sine Function
The tide is the regular rising or falling of the ocean's surface. This is due in large part to the gravitational forces of the moon. The following table represents water level of the tide off the coast of Kings Point, N.Y. for a 24 hour period.
February 9th through February 10th of 2009.
Use your graphing calculator to produce a sine regression model for the data in the table. Round a, b, c, and d to the nearest 0.0001. Then use your model to predict the height of the tide 30 hours after the original observation.
a. The height of the tide 30 hours after the original observation is -3.27 feet.
b. The height of the tide 30 hours after the original observation is 16 feet.
c. The height of the tide 30 hours after the original observation is 8 feet.
d. The height of the tide 30 hours after the original observation is -0.63 feet.

How can limit be used in real life
Answer:
Engineers use limits in real life.
Step-by-step explanation:
Limits are also used as real-life approximations to calculating derivataves. So to make calculations, engineers will approximate a function using small differences in the function and then try and calculate the derivative of the function by having smaller and smaller spacing in the function sample intervals.

The quadratic regression equation that fits these data is -1.107 X² +3.736 X +10.643 .
What is Quadratic Regression ?A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:
y=ax2+bx+c where a≠0 .
The best way to find this equation manually is by using the least squares method.
That is, we need to find the values of a ,b, and c such that the squared vertical distance between each point (xi,yi) and the quadratic curve y=ax2+bx+c is minimal.
After solving we get the values of a , b, and c and thus we form the equation
-1.107 X² +3.736 X +10.643

Maggie bought c CDs for $12 each, b books for $7 each, and a purse costing $24.
a. Write an expression to show the total amount of money Maggie spent.
b. If Maggie bought 4 CDs and 3 books, how much money did she spend?
Step-by-step explanation:
Given that,
Maggie bought c CDs for $12 each, b books for $7 each, and a purse costing $24.
(a) Cost of c CDs = 12c
Cost of b books = 7b
Cost of p purse = 24p
Total amount = 12c+7b+24p
(b) Cost of 4 CDs = 12(4) = $48
Cost of 3 books = 7(3) = $21
Hence, this is the required solution.

What is the inverse of the function y = 2x + 3?
Answer:
y = x/2 - 3/2
Step-by-step explanation:
Answer:
y = x/2 - 3/2
Step-by-step explanation:
First, get x on its own:
Subtract 3 from each side
y - 3 = 2x
Divide through by 2
y/2 - 3/2 = x
or x = y/2 - 3/2
Now simply switch labels: x↔y
y = x/2 - 3/2
f(x) = 3x2 – 2x - 9
g(x) = 3x2 + 2x2 - 4x - 9
Find (f - g)(x).
9514 1404 393
Answer:
(f -g)(x) = -3x^3 +x^2 +2x
Step-by-step explanation:
We assume the expression for g(x) has a typo, and the first term should be 3x^3.
(f -g)(x) = f(x) -g(x) = (3x^2 -2x -9) -(3x^3 +2x^2 -4x -9)
= 3x^2 -2x -9 -3x^3 -2x^2 +4x +9
= -3x^3 +(3 -2)x^2 +(-2+4)x +(-9+9)
(f -g)(x) = -3x^3 +x^2 +2x

Jill took a photograph of a plane taking off. Her mother is an air-traffic controller and was able to estimate the measurements shown. How far is the plane above the ground? Round to the nearest yard?
56 yards
75 yards
40 yards
60 yards
Answer:
75 yards .
Step-by-step explanation:
Let 90 yards be h ,50 yards be b and remaining side be p
h^2 = p^2 + b^2
90×90=p^2+50×50
90×90-50×50=p^2
root 5600=p
p=74.833
