The length of the enclosure for the pancake tortoise must be greater than the height. The volume of the enclosure is expressed in terms of the width, w.
w^3+6w^2-40w
Factor the expression, then match the factors to the dimensions they represent.
The factors of the expression w³ + 6w² - 40w = 0 is (w - 4) and (w + 10)
(w - 4) will be the height
(w + 10) will be the length
Given,
The length of the enclosure for the pancake tortoise will be greater than the height, that is: l > h
The volume of enclosure = w³ + 6w² - 40w
Where w is the width.
Now, factorize the expression:
w³ + 6w² - 40w = 0
10 - 4 = 6
10 × (-4) = -40
Therefore, the factors of the expression w³ + 6w² - 40w = 0 is (w - 4) and (w + 10)
Here, we know that length is greater than height.
So, (w - 4) will be the height and (w + 10) will be the length.

Find the value of x?
Step-by-step explanation:
so, we have a kite here.
a kite is a quadrilateral, that is totally symmetric along one of its diagonals.
the sum of all internal angles of a quadrilateral is always 360°.
remember, the sum of all angles around one point on one side of a line is always 180°.
a full circle airways represents 360°.
the inner angle at 140° is
180 - 140 = 40°
the inner angle at 250° is
360 - 250 = 110°
the inner angles at x and its opposing corner are equal (due to the symmetry) and are in sum with the other 2 inner angles 360°.
so, we have for the inner angles
360 = 110 + 40 + 2×xinner
210 = 2×xinner
the inner angle of x = 105°.
x (the outer angle of the inner angle of x) is
x = 360 - 105 = 255°
The quantity z varies directly with y and inversely with x When y = 12 and x = -12, z = -6. What is the value of k, the constant of variation?
Write your answer in the form A or A/B, where A and B are constants or variable expressions.
Answer:
Z = ky/x where y=12, x=-12 and z=-6
-6= k(12)/-12
-k = - 6

find the vertex and write the quadratic function in vertex form (which our openstax textbook also calls the standard form).
The vertex is (3,16) and the quadratic equation in vertex form is [tex]f(x)=(x-3)^{2}+16\\[/tex].
What is quadratic equation?Any equation in algebra that can be put into standard form is called a quadratic equation (from the Latin quadratus, which means "square").
As well as being referred to as the roots or zeros of the expression on the left-hand side of the equation, the values of x that satisfy it are known as solutions of the equation. There are only two possible answers to a quadratic equation. A double root is said to exist if there is only one solution. In the case where all of the coefficients are real values, there are either two real solutions, one real double root, two complex solutions that are complex conjugates of one another, or all three of the aforementioned options. If complex roots are taken into account, then a quadratic equation will always have two roots, with a double root counting as one. An equivalent equation can be created from a quadratic equation.
Calculations:
[tex]f(x)=x^{2} -6x+25\\ = x^{2} -2.x.3+(3^{2} )-(3^{2} )+25\\=(x-3)^{2} -9+25\\=(x-3)^{2}+16\\[/tex]
Comparing this from the vertex, y=[tex]a[/tex][tex](h-x)^{2} +k\\[/tex]
h=3 and k=16
Hence, vertex is (3,16).
[tex]f(x)=(x-3)^{2}+16\\[/tex]

What is an absolute value function?An absolute value function can be defined as a type of function that consist of an algebraic expression, which placed within absolute value symbols
How to determine the difference between depths?In order to determine the difference between depths, we would calculate the magnitude of the depth for each of the month.
For January, we have:
January depth = 20 - 6
January depth = 14 feet.
For July, we have:
July depth = 20 - 22
July depth = -2 feet.
Now, we can calculate the difference between depths in January and July:
Difference = 14 - (-2)
Difference = 14 + 2

Tau says that the
sum of -1 3/4 and 2 1/2 is the same as the difference
between 2 1/2 and 1 3/4. Is Tau correct? Explain why
or why not.
Tau is correct, the sum between -(1 ³/₄) and (2 ¹/₂) is equal to the difference between (2 ¹/₂) and (1 ³/₄)
Is Tau correct?
Remember that the sum between a number A and a negative number -B is written as:
A + (-B)
And that is equal to the difference between A and B.
A - B
In this case, Tau says that the sum between:
-(1 ³/₄) and (2 ¹/₂)
Is written as:
(2 ¹/₂) + (-(1 ³/₄) )
(2 ¹/₂) - (1 ³/₄)
And, using the above property, we conclude that this is equal to the difference between (2 ¹/₂) and (1 ³/₄)

d
f inverse of x is equal to the quantity 3 times x plus 2 end quantity over the quantity x minus 1 end quantity
The inverse function of f(x) = (x + 2)/(x - 3) is given as follows:
[tex]f^{-1}(x) = \frac{3x + 2}{x - 1}[/tex]
How to obtain the inverse function?The function in this problem is defined as follows:
f(x) = (x + 2)/(x - 3).
Using the notation y = f(x), it is given as follows:
y = (x + 2)/(x - 3).
To obtain the inverse, the first step is exchanging the variables x and y, as follows:
x = (y + 2)/(y - 3).
Now the variable y must be isolated to obtain the inverse function, as follows:
xy - 3x = y + 2
xy - y = 3x + 2
y(x - 1) = 3x + 2
y = (3x + 2)/(x - 1).

3*(x + 2) = 4x + 1
The first step is using the distributive property to distribute the left product.
3x + 6 = 4x + 1
Then we use the addition property of equality to subtract 4x in both sides, we will get:
-x + 6 = 1
And we use it again to subtract 6 in both sides:
-x = 1 - 6 = -5
Finally, we multiply both sides by -1 (multiplication property of the equality)

The total area under the normal curve is 1.
Why is there a standard deviation?
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.The more the data is distributed, the greater will be the standard deviation of that data. The standard deviation is used in finance by business owners to understand risk management and make better business decisions.
