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
Different forms of a quadratic function can be easier to use
than others. Each form has its own advantages, depending on
the kind of information that's needed for a given purpose.
• Design a chart, flow chart, mind map, or some other
visual to help you organize the information that can
easily be determined about the graph of a parabola
when the function is written in vertex form, standard
form, and factored form.
• Post your visual to the discussion board for other
students.

The time needs for second plane to catch up with first plane is t.
We have, 564(t + 0.5) = 744t
=> 180t = 282
=> t= 282/180 = 1.57 hour

PLEASE ANSWER. I will mark as brainliest for fist correct answer.
Step-by-step explanation:
If the total worth of the roll is 50 cents, we know that there are 50 pennies in the roll, and therefore the roll has a height of 50 * 1.52 = 76 mm. The radius of a penny is half its diameter, or 19.05 / 2 = 9.525.
We can find its volume with the formula (πr²) * h, where r and h are the radius and height respectively, and we can approximate 3.14 for π. Plugging these in, we have (3.14 * (9.525)²) * 76 ≈ 2160.8 mm³. Hope this helps!
Answer:
21,661.7 mm³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
Here, we're given the diameter as 19.05 mm, so the radius is ...
r = 19.05 mm / 2 = 9.525 mm
The thickness of one penny is 1.52 mm, but there are 50 of them in the roll. So the total height of this cylinder is ...
h = (1.52 mm)(50) = 76 mm
__
Using these numbers for radius and height in the volume formula, we find the volume of the roll of pennies to be ...
V = π(9.525 mm)²(76 mm) = 21,661.7 mm³
The approximate volume of the roll of pennies is 21,661.7 mm³.

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

y = mx+b where m is the slope and b is the y intercept
The slope is -3 and the intercept is 8
y = -3x +8
Answer: y= -3x+8
Step-by-step explanation:
Using the formula y=Mx+b

A house worth $150000 in 1999 increased by a constant rate to its value of $255 000 in 2007. Calculate the home's annual rate of increase in value.
Answer:
13125 per year
Step-by-step explanation:
2007-1999=8
255000-150000=105000
105000÷8=13125

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!
A circle has a radius of 6ft. What is the area of the sector formed by a central angle measuring 300 degrees
Answer:
30π ft^2 which is 94.25 ft^2 to the nearest hundredth.
Step-by-step explanation:
The area of the full circle is π * 6^2
= 36π so:
the area of the 300 degrees sector = 300 * 36 π / 360
= 30 π
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).
Answer:
slope is 4 and y-intercept is 12
Step-by-step explanation:
To solve this problem, let's actually just write the equation of the line in slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
Slope is change in y divided by change in x. Given (-3, 0) and (-2, 4), the slope will be: (4 - 0) / (-2 - (-3)) = 4 / 1 = 4. So, the slope is m = 4.
Now, our equation so far is y = 4x + b. To find b, plug in, say, -3 for x and 0 for y:
0 = 4 * (-3) + b
0 = -12 + b
b = 12
Then the slope is 4 and the y-intercept is 12.
Answer:
[tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} } = \frac{0 - 4}{-3+2} = \frac{-4}{-1} = 4[/tex]
4 is the slope
now we have to plug in the slope intercept formula where m is 4
you can find b by plugging one of the points
I choose (-3,0) since it is easier to work with
0 = 4(-3) + b
0 = -12 + b
12 = b
Our y intercept is 12
finally the slope intercept form is
y = 4x + 12
Slope formula - (y2 - y1)/ (x2-x1)
Slope intercept form = y = mx + b

Find the area of the shaded region.
Express the area in factored form.
Answer:
(x-1)(x+3)
Step-by-step explanation:
The area of the big green rectangle is just x(x+2) which is [tex]x^2+2x[/tex]. (Excluding the interior rectangle) The shaded area is just this minus three which is [tex]x^2+2x-3[/tex]. In factored form this is (x-1)(x+3).

What is the approximate area of the congruent orange right triangles?
A. 17 in2
B. 31 in2
C. 33 in2
D. 51 in2
Answer: The answer is A 17in2
Step-by-step explanation:
In the question it states that the triangles are congruent (both the same).
first I found the area of the top orange triangle.
the formula to find the area of a triangle is [tex]\frac{1}{2} bh[/tex] (base times Height).
so I did [tex]\frac{1}{2} 3.23* 5.12[/tex] which gave me 8.27.
Since the triangles are congruent (the same) they would both have the same area along with base and height. so I multiplied 8.27 by 2 (because there are two triangles) and got 16.54 which rounds up to 17.
the question also stated to find the APPROXIMATE area (close to the actual, but not completely accurate or exact.)

A. 17 in2

Please help. What is the height of the box in inches?
Answer:
h = 12 inches
Step-by-step explanation:
The volume is given by
V = Bh where B is the area of the base and h is the height
Substituting V = 1080 and B = 90
1080 = 90h
Divide each side by 90
1080/90 = 90h/90
12 = h
