The perfume company Scents 4 cents is about to release their latest perfume. The manager ordered 3 different perfume bottles customers can choose from. Approximate the volume of perfume each bottle can carry
Image and dimension of each bottle is attached
Answer:
Cyclinder = 572.56 cm³
Sphere = 381.70 cm³
Cone = 190.86 cm³
Step-by-step explanation:
Here, the manager ordered for three different shapes, which are: a sphere, cylinder and a cone. We are told to find the volume of each.
For the cylinder:
Given:
Radius, r = 4.5 cm
Height, h = 9 cm
The formula for calculating the volume of a cylinder is:
V = Base * height
Where base = πr²
= π * 4.5² = 63.62
Therefore,
V = 63.62 * 9
V = 572.56 cm³
For sphere:
Given:
Radius, r = 4.5 cm
Formula for volume of a sphere is:
[tex] V = \frac{4}{3} * \pi r^3 [/tex]
[tex] = \frac{4}{3} * \pi 4.5^3 [/tex]
= 381.7 cm³
For cone:
Given:
Radius, r = 4.5 cm
Height, h = 9 cm
The formula for calculating the volume of a cone is:
V = ⅓ * Base * height
Where base = πr²
= π * 4.5² = 63.62
Therefore,
V = ⅓*63.62 * 9
V = 190.86 cm³
Therefore the volume of perfume each bottle can carry is:
Cyclinder = 572.56 cm³
Sphere = 381.7 cm³
Cone = 190.86 cm³

Which relation is not a function?
Answer:
D.
Step-by-step explanation:
For a relation to be a function, one input cannot have multiple outputs.
In D, we can see that the input x = 1 will yield y = 4 and y = 1. So which one is it?
We cannot determine that, so this relation is not a function.
If the legs of an isosceles right triangle have a length of 15 StartRoot 2 EndRoot ft, what is the length of the hypotenuse? 7.5 feet feet feet 30 feet
Answer:
The length of the hypotenuse is 30 feet
Step-by-step explanation:
Here, we are to calculate the length of the hypotenuse of an iscosceles right triangle.
For the triangle to be isosceles, it means that the opposite and the adjacent are equal in length.
Now, to calculate the value of the hypotenuse, we make use of the Pythagoras’ theorem which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Mathematically;
let’s say the hypotenuse is length h feet
h^2 = {15√(2)}^2 + {15√(2)}^2
h^2 = (225 * 2) + (225 * 2)
h^2 = 450 + 450
h^2 = 900
h = √(900)
h = 30 feet
Answer:
30 feet

Element X decays radioactively with a half life of 12 minutes. If there are 510 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 11 grams?
Answer:
t = 66.4 minutes ( to the nearest tenth of a minute)
it would take the element 66.4 minutes to decay to 11 grams
Step-by-step explanation:
Given;
Initial amount N = 510 g
Final amount Nt = 11 g
Half life t(1/2) = 12 minutes
The amount of time t required for the Element X to decay from N to Nt can be written as;
t = ln(Nt/N) ÷ -λ .....1
Where;
λ = decay constant
λ = ln(2)/t(1/2)
Substituting λ, equation 1 then becomes;
t = ln(Nt/N) ÷ -(ln(2)/t(1/2))
Substituting the values;
t = ln(11/510) ÷ -(ln(2)/12)
t = −3.8365 ÷ -0.05776
t = 66.419
t = 66.4 minutes ( to the nearest tenth of a minute)

She dilated the outdoor stage by a scale factor of four with the center of dilation at the origin. Which ordered pair
will be the coordinates of one of the new vertices?
Answer:
(32, 16)
Step-by-step explanation:
Since the scale factor is 4, you always multiply both coordinate places (x and y) by this number.
The coordinates of one of the new vertices is (32, 16). Therefore, option D is the correct answer.
What is a dilation?Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.
Given that, rectangle with vertices A(-6, 4), B(8, 4), C(8, -2) and D(-6, -2).
Here, the scale factor is 4
So,
(-6,4) by a scale factor of 4(-6, 4)=(-24, 16)
(8, 4) by a scale factor of 4(8, 4)= (32, 16)
(-6, -2) by a scale factor of 4(-6, -2)= (-24, -8)
(8, -2) by a scale factor of 4(8, -2)= (32, -8)
Therefore, option D is the correct answer.

Your friend can eat a lot! Cheeseburgers from In-N-Out are his favorite, so he gets happy
when he eats them, that is, until he eats too many! If you measured his happiness, h(x),
based on how many cheeseburgers from In-N-Out he eats, x, you would get a curve modeled
by the function: ℎ() = −12 + 6 + 16....................................................................
Answer:
There are needed 3 burgers to reach the maximum measure of happiness of 25.Step-by-step explanation:
The given function is
[tex]h(x)=-x^{2} +6x+16[/tex]
Where [tex]x[/tex] is the number of burgers and [tex]h[/tex] the measure of happiness.
To find the maximum burgers needed to reach the maximum happiness, we just need to find the vertex of this function, which is defined as
[tex]V(h,k)[/tex] where [tex]h=-\frac{b}{2a}[/tex], and [tex]b=6[/tex], [tex]a=-1[/tex], replacing these values, we have
[tex]h=-\frac{6}{2(-1)}=3[/tex]
[tex]k=f(3)=-(3)^{2} +6(3)+16=-9+18+16=25[/tex]
Therefore, there are needed 3 burgers to reach the maximum measure of happiness of 25.
Using the maximum function relation, the maximum number of cheeseburgers to be consumed would be 25
Given the function :
h(x) = - x² + 6x + 16The function is maximum at [tex] \frac-{b}{2a}[/tex]
b = 6 ; a = - 1
Hence, we have :
[tex] x = \frac-{6}{2(-1)} = 3 [/tex]
Substitute x = - 3 into the function :
h(-3) = - (3)² + 6(3) + 16
h = - 9 + 18 + 16
h = 25
Therefore, the maximum number of cheeseburgers to be tanken would be 25

Emma substitutes 3 for x in a one-variable linear equation and finds that it makes the equation true. She then substitutes 5 for x then in the same linear equation true. What can you conclude about the number of solutions of the equation
Answer:
The equation has infinite solutions
Step-by-step explanation:
Linear equations can have zero, one or infinite solutions.
If Emma tested two values (3 and 5) for the same equation and they were both true solutions, this means that the equation has more than one solution.
If a linear equation has more than one solution, than the equation has infinite solutions.

Answer:
C) (negative 1, one-half), (0, 1), (1, 2), (2, 4)Step-by-step explanation:
The set C could be generated by an exponential function. The main reason is that exponential functions hava a restricted range, it can't have negative numbers or the number zero, because power can only be equal or greater than 1.
Additionally, for all exponentials, a null exponent gives 1 as an answer, so point (0, 1) is always present in an exponential function.
Therefore, the right answer is C.
The set of ordered pairs could be generated by an exponential function is C. (negative 1, one-half), (0, 1), (1, 2), (2, 4)
What is an exponential function?An exponential function simply means a relation that's in the form of y = ax².

1. Gertrude said her survey showed 2/3 of her math class liked hip hop music. There are 24 students in the class. Is it possible that Gertrude's survey is correct?
My Answer: Yes it's correct because 2/3 = 36 since 24/2=12 and 12*3=36
There are 24 students in the class. Take 2/3 of this to get (2/3)*24 = 16
A more detailed step by step would be
(2/3)*24 = (2/3)*(24/1) = (2*24)/(3*1) = 48/3 = 16
The result 16 is smaller than the original number 24. This is expected because 2/3 is smaller than 1. The key thing here is that the result 16 is a whole number.
You can think of 2/3 as the approximate percentage 66.7%, so you're applying roughly 66.7% to the entire class to get 16 people who like hip hop.
It appears you're thinking in reverse when you went from 24 to 36, because 2/3 of 36 is 24, but not the other way around. Keep in mind there are 24 students total in the class, and we can't go higher than this. We can't say there are 36 people who like hip hop.
So to answer the question, yes it is possible Gertrude's survey is correct because 2/3 of 24 is a whole number.
Let f (x) = 3x − 1 and ε > 0. Find a δ > 0 such that 0 < ∣x − 5∣ < δ implies ∣f (x) − 14∣ < ε. (Find the largest such δ.) What limit does this prove?
Answer:
This proves that f is continous at x=5.
Step-by-step explanation:
Taking f(x) = 3x-1 and [tex]\varepsilon>0[/tex], we want to find a [tex]\delta [/tex] such that [tex]|f(x)-14|<\varepsilon[/tex]
At first, we will assume that this delta exists and we will try to figure out its value.
Suppose that [tex]|x-5|<\delta[/tex]. Then
[tex]|f(x)-14| = |3x-1-14| = |3x-15|=|3(x-5)| = 3|x-5|< 3\delta[/tex].
Then, if [tex]|x-5|<\delta[/tex], then [tex]|f(x)-14|<3\delta[/tex]. So, in this case, if [tex]3\delta \leq \varepsilon[/tex] we get that [tex]|f(x)-14|<\varepsilon[/tex]. The maximum value of delta is [tex]\frac{\varepsilon}{3}[/tex].
By definition, this procedure proves that [tex]\lim_{x\to 5}f(x) = 14[/tex]. Note that f(5)=14, so this proves that f is continous at x=5.

Step-by-step explanation:
Write an equation expressing the given relationship. Solve it to find the numbers.
__
setupLet x represent "another number." Then the number I'm thinking of is ...
(3x -3)
and the product of that and "the other number" is 90:
x(3x -3) = 90
solutionx(x -1) = 30 . . . . . . divide by 3
We know the factors of 30 are ...
30 = 30·1 = 15·2 = 10·3 = 6·5
Of these factor pairs, the numbers that differ by 1 are 6 and 5. "The other number" is 6, and "my number" is 90/6 = 15.
My number is 15.
