How must the graph y=3x2+1 be transformed to obtain the graph of y=3x2−1?
A Each point on the graph of y=3x2+1 must be translated 2 units left.
B Each point on the graph of y=3x2+1 must be translated 2 units up.
C Each point on the graph of y=3x2+1 must be translated 2 units down.
D Each point on the graph of y=3x2+1 must be translated 2 units right.
There is a translation of 2 units down.
Option C is the correct answer.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
y = 3x² + 1
If we translate the graph 2 units down.
We get,
y = 3x² + 1 - 2
y = 3x² - 1
This is the graph we are looking for.
i.e
y = 3x² - 1
Thus,
There is a translation of 2 units up.

A flight with 104 passengers takes off at 1:15. The plane travels 560 miles in 1 hour. At that speed, how far will the plane travel in 3 hours? What information is needed to answer the question?
Answer:
To find how far the plane will travel, we need the time and length it traveled previously to form the MPH (miles per hour)
Using this information we can make an equation
560/1 = 560 miles in 1 Hour
x/3 = X miles in 3 Hours
560/1 = X/3
X= 1680

Rewrite with only sin x and cos x.
sin 3x - cos x (6 points)
Select one:
a. 2 sin x - sin3x - cos x
b. 2 sin x cos2x + sin x - 2 sin3x - cos x
c. 2 sin3x cos4x + 1
d. 3 sin x cos x - sin3x - cos x
Answer:
sin(3x) = sin(x + 2x)
= sinx cos(2x) + cosx sin(2x)
= sinx [1 - 2sin2x] + cosx [2sinxcosx]
= sinx - 2sin3x + 2cos2xsinx

The sum of two numbers is 23. Twice one number increased by 6 is the same as 4 times the other number decreased by 2. What is the largest of the two numbers?
Answer:
One number is 4.2, the other is 18.8
Step-by-step explanation:
1.) x+y=23
(x+6y)x2=4
2.) (x+6y)x2=4 = 2x+12y=4
3.)Use elimination/substitution to solve
2x+12y=4 = x+6y=2 = x=2-6y
2-6y+y=23
4.)Solve for y
2-5y=23 -> -5y=21 -> y=4.2.
5.)Solve for x
x+4.2=23
x=18.8

A mass weighing 9 lb stretches a spring 1.5 in. The mass is displaced 5 inch in the downward direction from its equilibrium position and released with no initial velocity. Assuming that there is no damping, and that the mass is acted on by an external force of 5 cos(6t) lb, solve the initial value problem describing the motion of the mass. For this problem, please remember to use English units: ft, lb, sec.
Answer:
[tex]9u" + 2304u = 160cos(6t)[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex] and [tex]u'(0) =0[/tex]
Step-by-step explanation:
Given
[tex]w =9lb[/tex] --- weight
[tex]L = 1.5in[/tex] --- stretch
[tex]u(0) =5in[/tex] --- initial position
[tex]u'(0) =0[/tex] --- initial velocity
[tex]\gamma =0\ lbs/ft[/tex] --- no damping
[tex]F(t) = 5cos(6t)\ lb[/tex] -- External force
Required
Solve the initial value problem
The initial value problem is calculated using:
[tex]mu" + ku = F(t)[/tex]
First, convert all lengths to ft
[tex]L = 1.5in[/tex]
[tex]L = \frac{1.5}{12}ft[/tex]
[tex]L = \frac{1}{8}ft[/tex]
[tex]u(0) =5in[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex]
Weight is calculated as:
[tex]w = mg[/tex] and [tex]w = kL[/tex]
Where
[tex]g = 32fts^{-1}[/tex]
Make m the subject in [tex]w = mg[/tex]
[tex]m = \frac{w}{g}[/tex]
[tex]m = \frac{9}{32}[/tex]
Make k the subject in [tex]w = kL[/tex]
[tex]k = \frac{w}{L}[/tex]
[tex]k = \frac{9}{1/8}[/tex]
[tex]k = 72[/tex]
Recall that: [tex]mu" + ku = F(t)[/tex]
[tex]\frac{9}{32}u" + 72u = 5cos(6t)[/tex]
Multiply through by 32
[tex]9u" + 2304u = 160cos(6t)[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex] and [tex]u'(0) =0[/tex]

Joanna is reading a storybook. The ratio of the number of pages she read to
the pages that remain to be read is 7:3. If the book contains 500 pages in all,
how many pages did Joanna read and how many pages remain to be read?
Answer:
The amount of pages that remain to be read is 150 pages
Step-by-step explanation:
Okay if we know it's in 7:3 ratio we can easily add them both to get 10, then divide 10 by 500 to get 50. SO we now know that 50 is 1 unit and since the ratio says 3 units is the answer, we multiply 50 by 3 to get 150.

Answer:
115 adults and 156 children were admitted at the amusement park.
Step-by-step explanation:
Given that the admission fee at an amusement park is $ 2.25 for children and $ 5.40 for adults, and on a certain day 271 people enter the park and the admission fees collected a total of $ 972, to determine how many children and how many adults were admitted se you must perform the following calculation:
5.40 - 2.25 = 3.15
271 x 2.25 = 609.75
(972 - 609.75) / 3.15 = X
362.25 / 3.15 = X
115 = X
(115 x 5.40) + ((271-115) x 2.25) = X
621 + (156 x 2.25) = X
621 + 351 = X
972 = X
Thus, 115 adults and 156 children were admitted at the amusement park.
