Review the graph of a piecewise function. On a coordinate plane, a line starts at open circle (0, negative 1) and goes to open circle (negative 2, negative 3). It then curves up through (negative 5, 2). A curve starts at closed circle (0, 3) and curves down and approaches x = 1 into quadrant 4. Another curve starts at closed circle (2, 3) and curves down and approaches x = 1 in quadrant 4. A horizontal line goes from closed circle (2, 3) to (5, 3). Which list represents all values of x for which the function has a discontinuity? 1 0 and 1 –2 and 1 –2, 0, and 1

A cylinder with a diameter of 24 inches and a height of 8 inches has the same volume as a cone with a diameter of 12 inches.
What is the height of the cone?
A. 4 Inches
B. 16 inches
C. 48 inches
D. 96 Inches
Answer:
D. 96 inches.
Step-by-step explanation:
Radius of cylinder = 1/2 * 24 = 12 inches.
Radius of the cone = 1/2 * 12 = 6 inches.
Volume of the cylinder = pi r^2 h and volume of the cone = 1/3 pi r^2 h
So pi 12^2 * 8 = 1/3 pi * 6^2 * h
1152 pi = 12 pi h
h = 1152/12
h = 96 inches.

Answer:
x =14
<A = 7x -11 = 87
<B = 2x-3 = 25
<C = 5x -2 = 68
Step-by-step explanation:
The sum of the angles add to 180
7x -11 + 2x-3 + 5x-2 = 180
Combine like terms
7x +2x+5x -11-3-2 =180
14x-16=180
Add 16 to each side
14x-16+16 =180+16
14x = 196
Divide each side by 14
14x/14 =196/14
x =14
<A = 7x -11 = 7*14 -11 = 98-11 = 87
<B = 2x-3 = 2*14 -3 = 28-3 = 25
<C = 5x -2 = 5*14 -2 = 70-2 = 68

C y= 1/2x -10

Answer:
D. y= 2x + 10
Step-by-step explanation:
Try x=3 in the equations and see which one works.
A: 2·3 -10 = -6 ≠ 16
B: 1/2(3) +10 = 11.5 ≠ 16
C: 1/2(3) -10 = -8.5 ≠ 16
D: 2(3) +10 = 16 . . . . . . this equation works

Answer: 54.4
Step-by-step explanation:
A finite sequence of numbers is called AWESOME if each subsequent member of the sequence, except the first one, is larger than the previous one and if the
product of all the members of that sequence is a perfect square. For example, sequence 2, 6, 27 is an AWESOME sequence. Determine the natural numbers x and y such that the sequence 28, x, y, 65 is an AWESOME sequence.
Answer:
The answer is "28, 35, 52, 65"
Step-by-step explanation:
Calculating the x,y:
[tex]\to x< y<65\\\\\to 65 \times 28 xy=13 \times 5xy \times 7 \times 2^2\\\\x=13 \\\\y=5 \times 7= 35\\\\[/tex]
When
or
[tex]x=35\\\\y= 13 \times 2^2=13 \times 4 =52[/tex]
So, the final answer is "28, 35, 52, 65".

PLEASE HELP BRO IM FAILING MATH
Answer:
Step-by-step explanation:
we have several angles that have the same vertex and so they are congruent
1) e = 35 degrees because the opp angle has this measure
2) d = 109 degrees for the reason above
3) for find f we have to notice that the sum of the three angles (if you look at the vertical line you can notice that it is a straight line, so describes two angles whose measures are 180 degrees)
f = 180 - (35 + 109)
f = 180 - 144 = 36 degrees
A culture of the bacterium Salmonella enteritidis initially contains 50 cells. When introduced into a nutrient broth, the culture grows at a rate proportional to its size. After 1.5 hours, the population has increased to 775. (a) Find an expression for the number of bacteria after t hours. (Round your numeric values to four decimal places.)
Answer:
The expression for the number of bacteria after t hours is [tex]P(t) = 50e^{0.2922t}[/tex]
Step-by-step explanation:
When introduced into a nutrient broth, the culture grows at a rate proportional to its size.
This means that the size of the population, after t hours, is modeled by the following differential equation:
[tex]\frac{dP}{dt} = rP[/tex]
In which R is the growth rate.
The solution of this differential equation is:
[tex]P(t) = P(0)e^{rt}[/tex]
In which P(0) is the initial population.
A culture of the bacterium Salmonella enteritidis initially contains 50 cells.
This means that [tex]P(0) = 50[/tex], and so:
[tex]P(t) = P(0)e^{rt}[/tex]
[tex]P(t) = 50e^{rt}[/tex]
After 1.5 hours, the population has increased to 775.
This means that [tex]P(1.5) = 775[/tex]. We use this to find r. So
[tex]P(t) = P(0)e^{rt}[/tex]
[tex]500e^{1.5r} = 775[/tex]
[tex]e^{1.5r} = \frac{775}{500}[/tex]
[tex]\ln{e^{1.5r}} = \ln{\frac{775}{500}}[/tex]
[tex]1.5r = \ln{\frac{775}{500}}[/tex]
[tex]r = \frac{\ln{\frac{775}{500}}}{1.5}[/tex]
[tex]r = 0.2922[/tex]
The expression is:
[tex]P(t) = 50e^{rt}[/tex]
[tex]P(t) = 50e^{0.2922t}[/tex]
The expression for the number of bacteria after t hours is [tex]P(t) = 50e^{0.2922t}[/tex]

Two people meet in the purple room on the fourth floor of a building. On departure, one person travels West 20 feet, South 12 feet, and Down 12 feet. The other person travels North 20 feet, East 10 feet, and Up 12 feet. How far apart are the two people? Round to the nearest tenth.
Answer:
50 feet
Step-by-step explanation:
Set up a 3-dimensional coordinate system (see the attached image).
This setup shows an axis that runs North-South (South is negative, North is positive), an axis that runs East-West (East is positive, West is negative), and an axis that runs Up-Down (Up is positive, Down is negative).
The two points in question are then:
First person's location (12, -20, -12), and the second person's location is (-20, 10, 12).
The distance between two points [tex]\left( x_1,\,y_1,\,z_1\right)[/tex] and [tex]\left( x_2,\,y_2,\,z_2\right)[/tex] is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2[/tex]
[tex]d=\sqrt{(-20-12)^2+(10-(-20))^2+(12-(-12))^2}\\\\d=\sqrt{(-32)^2+30^2+24^2}\\\\d=\sqrt{2500}\\\\d=50[/tex]

Yoonie is a personnel manager in a large corporation. Each month she must review 16 of the employees. From past experience, she has found that the reviews take her approximately four hours each to do with a population standard deviation of 1.2 hours. Let Χ be the random variable representing the time it takes her to complete one review.Assume Χ is normally distributed.Let be the random variable representing the mean time to complete the 16 reviews. Assume that the 16 reviews represent a random set of reviews.
A. Find the probability that the mean of a month’s reviews will take Yoonie from 3.5 to 4.25 hrs. Sketch the graph, labeling
and scaling the horizontal axis. Shade the region corresponding to the probability.

Help me please I will give brainleist
Answer:
? = 7x
Step-by-step explanation:
Lets simplify the equation first;
5x - 20 + ? = -20 + 12x
=> So now, we have to make the equation on the left equation congruent to the right equation:
It we already have -20 common on both sides, but we need to find out, what added by 5x gives us 12x,
=> So we can let the number we have to find out be y, and say:
5x + y = 12x
=> y = 12x - 5x
=> y = 7x
Therefore, ? = 7x
Hope this helps!
