Volume of a box If a box has a volume of 42 cubic feet, is it possible for you to
fit inside the box? Explain your answer
Answer:
yes ,because the average human hight
cannot exceed 7squared feets
Without knowing the dimensions of the box or the size of the person, we cannot determine whether the person can fit inside the box or not.
What is a box?In mathematics, a box is a three-dimensional shape that has six rectangular faces.
It is also called a rectangular prism.
The faces on opposite sides of a box are congruent and parallel. A box has a height, width, and length, which are usually labeled as h, w, and l.
The volume of a box can be found by multiplying its length, width, and height: V = l × w × h.
We have,
The volume of a box is a measure of the amount of space inside the box, typically measured in cubic units such as cubic feet or cubic meters.
If a box has a volume of 42 cubic feet, it is simply telling us the amount of space inside the box.
Whether a person can fit inside the box or not depends on the size of the box and the size of the person.
Without knowing the dimensions of the box or the size of the person, we cannot determine whether the person can fit inside the box or not.
So,
We need more information to answer this question.
Thus,
Without knowing the dimensions of the box or the size of the person, we cannot determine whether the person can fit inside the box or not.

a woman 1.65. tall stood 50m away from the foot of a tower,and observe that the angle of elevation of the top of the tower to be 50⁰ what is the height of the tower
[tex]\sf\huge\underline{\star Solution:-}[/tex]
[tex]\rightarrow[/tex]Let the women's height be AE and distance between the women and tower be AC.
Also let the height of tower be BC.
[tex]\rightarrow[/tex]Now, clearly it is forming a triangle.
So, in triangle ABC,

Hope it helps you:)
Answer:
61.24 m to the nearest hundredth.
Step-by-step explanation:
tan 50 = H / 50
H = 50 tan 50
Height of the tower = H + height of the woman

Match each action with its effect on the set of scores shown. Use each action only once.
90, 85, 35, 70, 67, 76, 90, 79, 94, 100, 87, 61, 56, 80, 67, 65
The change that will occur to the mean, median, mode of the data matched as follows:
1. e
2. b
3. d
4. a
5. c
What is the Mean fo a Data Set?To find the mean, the sum of all the values is divided by the number of values.
Given the data, 90, 85, 35, 70, 67, 76, 90, 79, 94, 100, 87, 61, 56, 80, 67, 65, therefore:
1. 35 is an extreme value, so it is an outlier. If we remove 35, the greatest change will be on the mean. (e)
2. If we remove 90, 67 will have the highest frequency. This means the mode of the data will change to 67. (b)
3. If 76 is removed from the data, the median of the data would be 79. (d)
4. If we remove 100, the range of the data would be, 94 - 35 = 59. (a)
5. If we remove 94, the mean of the data = 1108/15 = 73.87
This means the mean of the data will change to 73.87 if we remove 94. (c)

Form a polynomial whose zeros and degree are given. Zeros: 2, multiplicity 1; 4, multiplicity 2; degree 3
Answer:
If the polynomial is degree 3, then it is of the form y = Ax3 + Bx2 +Cx + D
And if the zeros are -2 with multiplicity of 1, then the factor is (x+2)1 = x+2
The other zero is -4 with multiplicity of 2, so it's factor is (x+4)2 = x2 +8x+16
So in general, if we let A = 1, then the polynomial is y = (x+2)(x+4)2 which multiplies out to
(x+2)(x2+8x+16) = x3 + 8x2 + 16x + 2x2 + 16x + 32
Combining like terms gives the polynomial:
y = x3 +10x2 + 32x + 32
If A is not 1, then y = A(x3 +10x2 + 32

Find all relative maximum and minimums of f(x) =2x^3-3x^2-12x+5 Explain your steps in detail.
Answer:
The relative minimum is (3,-4) and the relative maximum is (-2,1)
Step-by-step explanation:
The first step is to take the derivative of f(x)
By using the power rule which is d/dx x^n=nx^n-1 you will find that the derivative is 6x^2-6x-12
The next step is to set the derivative = to 0 and by doing that you will obtain x being equaled to -2 and 3
Put -2 and 3 on a sign chart and determine the behavior for both of those functions
The outcome of your sign chart should be + - + because of the odd multimplicity of (x-3) and (x+2).

By plugging in 3 into f(x), you get -4 and by plugging in -2 into f(x) you get 1

How to evaluate the piece-wise function?The function is given as:
[tex]f(x) = \left[\begin{array}{cc}x-3&x\le-4\\3x-2&-4 < x\le 2\\-2x+4&x > 2\end{array}\right][/tex]
The above definition means that:
All x values less than or equal to -4 would be evaluated using f(x) = x - 3All x values greater than -4 but less than or equal to 2 would be evaluated using f(x) = 3x - 2All x values greater than 2 would be evaluated using f(x) = -2x + 4Using the above highligts, we have:
f(-4) = -4 - 3 = -7
f(-2) = 3(-2) - 2 = -8
f(0) = 3(0) - 2 = -2
f(2) = 3(2) - 2 = 4
f(4) = -2 * 4 + 4 = -4
f(8) = -2 * 8 + 4 = -12
