Answer:197.8
The formula for a cylinder is 3.14*r^2*h but if you don't round to the nearest tenth the the answer is 197.82034.
Step-by-step explanation:Step one mutiply 3^2=9, Step two mutiply 3.14*
9=28.26, Step three mutiply 28.26*7=197.82.But if you round 197.82034 to the nearest tenth which is moving one decimal place to the right you'll will get 197.8.
Solve for x. Enter the solutions from least to greatest.
(x - 3)^2 - 81 = 0
lesser x=
greater x =
Answer:
lesser x = -6
greater x = 12
Step-by-step explanation:
(x - 3)^2 - 81 = 0
(x - 3)^2 = 81
x - 3 = +/- 9
x - 3 = 9 or x - 3 = -9
x = 12 or x = -6

What is a absolute value equation?To solve an equation containing absolute value, isolate the absolute value on one side of the equation. Then set its contents equal to both the positive and negative value of the number on the other side of the equation and solve both equations.
From the given graph, the vertex is (7, -3).
x-intercept(s): (10,0),(4,0)
y-intercept(s): (0,4)
We know that, general form of the absolute equation is f(x)=a|x-h|+k.
Here, equation is f(x)=|x-7|-3
Therefore, option B is the correct answer.

1) Identify the mean, median, and range of the
data set below.
4, 8, 12, 15, 6, 9, 11
Mean:
Median:
Range:
Answer:
Mean: 9.2857142857143
Median: 9
Range: 11
Step-by-step explanation:
The mean is the average of the data set. Add all the numbers up then divide by the amount of numbers you had to start with.
The median of a set of data is the middlemost number. Order your set into least to greatest order then count inwards. If you have an even set or number then add both middle numbers and divide by 2.
The range of a set of data is the difference between the highest and lowest values in the set. Find your lowest and highest value numbers and subtract the lowest number form the highest one.
find the volume of the figure
Answer:
1920
Step-by-step explanation:
Volume of larger rectangular prism: 10 * 8 * 14 = 1120
Volume of smaller rectangular prism: 10 * 10 * 8 = 800
Volume of whole prism: 1120 + 800 = 1920
Hence, your answer is 1920
At a yard sale, Enzo sees a sign that advertises "0.05 cents per used book." Using the advertised price, determine the cost of 40 used books. pls answer.........................,...........................................
Answer: The answer would be “$2.”
Step-by-step explanation: To find this answer you would take the amount per book which is 0.05 cents per used book. And then multiply it by how many books you are buying which is 40. So when you multiply 40 by 0.05 you get “$2 for 40 used books.”

Answer:
h(x) = 1/2 |x - 1| - 2h(x) = - (x + 2)² + 3Step-by-step explanation:
See attachedYou need to recognize the parent function by looking at the graph. Then you need to find out how different is the graph from the parent function and finally work out the equation of the graph considering the transformations.
4)
The parent function is the absolute value function:
h(x) = |x|Its vertex is at the origin. We see the vertex has shifted and also the slope has changed.
We can find the slope easily, the ratio of rise to run is 1/2
The function becomes:
h(x) = 1/2 |x|Now considering the translation. We see the vertex has coordinate of (1, -2)
It means the graph has shifted 1 unit right and 2 units down.
The shift right is shown as:
h(x) = 1/2 |x - 1|and adding the shift down:
h(x) = 1/2|x - 1| - 2This is our final equation.
5)
Parabola is the graph of the quadratic function.
The vertex form of the function is:
h(x) = a(x - h)² + k, where (h, k) is the vertexNow, we see it is opening down and the vertex is at (-2, 3):
h(x) = a(x - (-2))² + 3 = a(x + 2)² + 3To find the value of a we can use a point on the graph. Let's use point (0, -1):
-1 = a(0 + 2)² + 3-1 = 4a + 34a = -4a = -1The function is:
h(x) = - (x + 2)² + 3
Which shows a pair of similar circles ?
Answer:
d) I, II and III.
Step-by-step explanation:
Two circles are similar when the two circles have different or equal radii. In case I, we have similar circles that are congruent and non-concentric, since their radii are equal. In case II, we find two similar circles which are secant to each other. Lastly, the case III represents two similar circles which are concentric.
Therefore, I, II and III show pairs of similar circles.

What is Graph?
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Quadrilateral RUST has a vertex at R (1,5)
We have to find the coordinates of R after the translation (x,y) of (x+ 1, y - 2)
(1, 5)-->(1+1, 5-2)
Coordinates after translation are (2, 3)
Now by a dilation by a scale factor of 3, centered at the origin
so R'(6, 9)
Hence, (6, 9) are the coordinates of R after the translation (x,y) (x+ 1, y - 2),followed by a dilation by a scale factor of 3,

In a bag of balls, 3 are yellow, 4 are blue, 6 are green, and 2 are red. Kay
picks 30 balls from the bag, replacing the ball into the bag each time. How
many times would you expect a green ball to be picked?
Answer:
12 marbles
Step-by-step explanation:
First, add the marbles together.
3 + 4 + 6 + 2 = 15
Then, put the 6 in the numerator.
6/15
Next, multiply by 2 to make the denominator 30.
12/30
Kay should expect 12 out of her 30 marbles to be green

Step-by-step explanation:
dw probability is confusing to a lot of ppl
so if you count the sections theres 8 in all
to see the probability we must find how many times we will get a positive outcome, or what we want (the multiple of 3)
lets see how many multiples of 3 there are
theres 3 and 6
thats two out of the eight possible outcomes at any moment u spin the spinner
so thats an 2/8 chance
you can simplify that fraction to a 1/4 chance, so its the second option on your screen
Solve w = x + for y.
Reply really fast and give like the work for it too please
Answer:
see below
Step-by-step explanation:
w = x+y/z
Subtract x from each side
w-x = x+y/z -x
w-x = y/z
Multiply each side by z
(w-x) *z = y/z*z
(w-x) *z = y
You can distribute the z if desired
wz -xz = y
Answer:
y = z(w - x)
Step-by-step explanation:
w = x + y/z
Subtract x from both sides
w - x = y/z
Multiply both sides by z
z(w - x) = y
Flip
y = z(w - x)
