14. The water level in a tank can be modeled by the function h(t)=8cos +11.5, where t is the number of
hours since the water level is at its maximum height, h. How many hours pass between two consecutive
times when the water in the tank is at its maximum height?
I
Answer:
2π hours
Step-by-step explanation:
Given the following function:
h(t)=8*cos(t) + 11.5
we want to find its period. This function has the following form:
y = A*cos(B(x + C)) + D
where:
A = 8
B = 1
C = 0
D = 11.5
which period is computed as: 2π/B. Then, for the case of the problem:
period = 2π/1 = 2π hours
Solve for x
8+10x-3x^2=0
Answer: x = 4
or x= -2/3 = -0.667

James is putting 24 jelly beans into equal rows. He says there will be more jelly beans in 2 equal rows
than in 3 equal rows. Is James correct? Explain.
Select the correct answer below, and fill in the answer box(es) to complete your choice.
(Type a whole number.)
OA. Yes. James is correct. There are fewer rows, so there will be more in each row. There will be
jelly beans in each row for 2 equal rows, and jelly beans in each row for 3 equal rows.
OB. No. James is not correct. There are fewer rows, so there will be fewer in each row. There will be
jelly beans in each row for 2 equal rows, and jelly beans in each row for 3 equal rows.
OC. No. James is not correct. It doesn't matter how many rows there are. There will always be
jelly beans in each row.

Answer:
(A)James is correct.There are fewer rows, so there will be more in each row. There will be 12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.
Step-by-step explanation:
James is putting 24 jelly beans into equal rows.
If he puts the jelly beans in 2 equal rows:
Number in each row=24/2=12 jelly beans per row.
If he puts the jelly beans in 3 equal rows:
Number in each row=24/3=8 jelly beans per row.
Therefore, James is correct.There are fewer rows, so there will be more in each row. There will be 12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.
The correct option is A.

Which compound inequality is equivalent to the absolute value inequality |b| greater than 6? –6 > b and b > 6 b > –6 or b < 6 –6 < b and b > 6 b < –6 or b > 6
Answer:
The correct inequality is: b< -6 or b > 6
Step-by-step explanation:
The absolute value operator always results in a positive number, in such a way that if b > 0, then |b| = b, while if b < 0, then |b| = -b. With this in mind, let's look at the inequality given:
|b| > 6
This will be true for values of b that are greater than 6 and values of b that are less than -6, due to the absolute value operator. Therefore the compound inequality that represents this situation is:
b< -6 or b > 6
Answer:
I think it is D (and)
Step-by-step explanation:
"Or" means that the b value can be less than -6 or greater than 6
so it could satisfy either one
so if you plug in a value that satifies one of the inequalities (ex: -7)
|-7|>6 and it works!

If you save $3,000 at an interest rate of 14 percent per year, how much will you have at the end of six years? The interest should be compounded. A. $5,805.96 B. $6,502.34 C. $6,584.91
Answer:
C.) $6,584.91
Step-by-step explanation:
Amount earned in compound interest = P(1 + r)^n;
where P is the principal,
r is the rate and n is the number of periods.
Amount = 3,000(1 + 14%)^6 = 3,000(1 + 0.14)^6 = 3,000(1.14)^6 = $6,584.91

===========================================================
Work Shown:
Point A starts at (-2,3) and moves to (2,5) after applying the translation rule of "shift 4 to the right, 2 up".
Use the distance formula to find the distance from (-2,3) to (2,5)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-2-2)^2 + (3-5)^2}\\\\d = \sqrt{(-4)^2 + (-2)^2}\\\\d = \sqrt{16 + 4}\\\\d = \sqrt{20}\\\\d = \sqrt{4*5}\\\\d = \sqrt{4}*\sqrt{5}\\\\d = 2\sqrt{5}\\\\d \approx 4.472136\\\\[/tex]

What are the slope and the y-intercept of the linear function that is represented by the graph?
On a coordinate plane, a line goes through points (negative 3, 0) and (negative 2, 4).
The slope is 3, and the y-intercept is 9.
The slope is 3, and the y-intercept is 12.
The slope is 4, and the y-intercept is 9.
The slope is 4, and the y-intercept is 12.
Answer:
The slope is 4, and the y-intercept is 12.
Step-by-step explanation:
In the given question, the line goes through points (-3,0) and (-2,4).
We need to find the slope and the y-intercept of the line.
Finding Slope:Slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
With points (-3,0) and (-2,4):
[tex]m=\frac{4-0}{-2-(-3)}=\frac{4}{1}=4[/tex]
The slope of the line is 4.
Finding y-intercept:An appropriate equation for what we have so far is:
[tex]y=4x+b[/tex]
We can solve for 'b' to get the y-intercept.
Replace 'x' and 'y' with one of the coordinates and solve for 'b':
[tex]4=4(-2)+b\\4*-2=-8 \leftarrow \text {Distribute}\\4=-8+b\\4+8=-8+8+b \leftarrow \text {Addition Property of Equality} \\\boxed {12=b}[/tex]
The y-intercept is 12.
Final Answer:The answer should be: "The slope is 4, and the y-intercept is 12."
Answer:
The answer is d, which is the slope of 4 and the y- intercept is 12.
