How to determine a family of cubic functions
Cubic functions are polynomials of grade 3. In this case, we have pairs of cubic functions of the following form:
y = (x - h)³ + k (1)
y = - (x - h)³ + k (2)
a) Where (h, k) are the coordinates of the vertex of each cubic function. There is a translation of (x, y) = (3, 1) between each two consecutive pairs of cubic functions. Hence, we have the following fourteen cubic functions:
y = (x + 9)³ - 3y = - (x + 9)³ - 3y = (x + 6)³ - 2y = - (x + 6)³ - 2y = (x + 3)³ - 1y = - (x + 3)³ - 1y = x³ y = - x³y = (x - 3)³ + 1y = - (x - 3)³ + 1y = (x - 6)³ + 2y = - (x - 6)³ + 2y = (x - 9)³ + 3y = - (x - 9)³ + 3b) Another family of functions with a similar pattern is shown below:
y = (x + 9)² - 3y = - (x + 9)² - 3y = (x + 6)² - 2y = - (x + 6)² - 2y = (x + 3)² - 1y = - (x + 3)² - 1y = x² y = - x²y = (x - 3)² + 1y = - (x - 3)² + 1y = (x - 6)² + 2y = - (x - 6)² + 2y = (x - 9)² + 3y = - (x - 9)² + 3To learn more on cubic functions: https://brainly.com/question/25732149

What is the equation of a line parallel to y=(3)/(4)x-5 and passes through (12,-2)?
Answers
A parallel line has the same slope as the original line. So in this case the slope of the line is also 3/4. Now how do we know if it intersects the point? We need to adjust the y intercept.
Currently, we know the equation of the line is y= 3/4 x + b, where b is the thing we are looking for. We also have a point, which supplies the x and y. Plug that in and solve for b
-2 = (3/4)*(12) + b
You'll get b= -11
So the equation of the parallel line intersecting the point given is y= 3/4x -11.
I am assuming that the slope is 3/4 based on the way you formatted the original equation, but it's the same steps if the slope is different.

We have 6 of 1/2 cups, 2 of 1/4 cups and 2 of 3/4 cups
So there are a total of [6•(1/2)]+[2•(1/4)]+[2•3/4]=5 cups for the total of 10 pancakes
Therefore, the average amount of milk used for an order of pancakes is 5/10=1/2 cups.

Answer:
3.) (5,2), (5,5), and (9,2)
Step-by-step explanation:
The triangle currently has the coordinates (2,0), (6,0), and (2,3).
If you want to translate the triangle up 2 units, you need to add 2 to each "y" value.
(2,0) -----------> y = 0 ------------> new y = 2
(6,0) -------> y = 0 --------------> new y = 2
(2,3) ----------> y = 3 -----------> new y = 5
If you want to translate the triangle 3 units to the right, you need to add 3 to each "x" value.
(2,0) -----------> x = 2 ------------> new x = 5
(6,0) -------> x = 6 --------------> new x = 9
(2,3) ----------> x = 2 ----------> new x = 5
Therefore, the new coordinates are (5,2), (9,2), and (5,5).

The theoretical probabilities are
Red: 8/20 = 0.4
Blue:6/20 = 0.3
yellow:6/20 = 0.3
The experimental Probabilities are
Red: 11/40 = 0.275
blue: 11/40 = 0.275
Yellow: 18/40=0.45
Both probabilities add to 1 as they should
The yellow is the highest disproportionate answer and it really shouldn't be. If anything it should be red. (0.45 > 0.4 comparing yellow experimental with red theoretical. The yellow is way more than it should be)

A timer is started and a few moments later a swimmer dives into the water and then comes back up. The swimmer's depth (in feet) as a function of time (in seconds after the timer was started) is given by the equation h(t)=t2−12t+27
Rewrite the formula in factored form and select each true statement below.
The swimmer is underwater for 12 seconds.
The swimmer dives into the water 3 seconds after the timer was started.
The swimmer comes back up 9 seconds after the timer was started.
The swimmer dives to a maximum depth of 27 feet.
The swimmer dives into the water 12 seconds after the timer was started.
Answers
The formula in factored form is (t - 3)(t - 9) and the swimmer dives into the water 3 seconds after the timer was started also, the swimmer comes back up 9 seconds after the timer was started.
Analysis:
at h(t) = 0 that is when the diver has not dived or at height 0 foot
the equation becomes [tex]t^{2}[/tex] -12t + 27 = 0
by factorizing,
[tex]t^{2}[/tex] -9t -3t + 27 = 0
(t-9)(t-3) = 0, this is the equation in factored form.
t = 3 or 9
These are the times, the height h(t) = 0
Which means the swimmer dived 3 seconds later or got to the top of water after 9 seconds in which case h(t) = 0
In conclusion, the swimmer dives 3 seconds later after the timer was started and the swimmer comes back up after 9 seconds are the true statements for this problem.

Answers
The center of the circle will be (4, -3) and the radius of the circle will be 6 units. Then the correct option is A.
What is an equation of a circle?A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at the (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x - h)² + (y - k)² = r²
The equation is given below.
x² - 8x + y² + 6y - 11 = 0
x² - 8x + y² + 6y = 11
Then the center and the radius of the circle will be
x² - 8x + 16 + y² + 6y + 9 = 11 + 16 + 9
(x - 4)² + (x + 3)² = 36
(x - 4)² + (x + 3)² = 6²
Thus, the center and the radius of the circle will be (4, -3) and 6 units respectively.
