Given the following data:
Length of right triangular base = 9 centimeters and 15 centimeters.
Height of right triangular base = 32 centimeters.
How to calculate the volume of a pyramid?Mathematically, the volume of a pyramid can be calculated by using this formula:
Volume = 1/3 × b × h
Where:
h is the height of a pyramid.
b is the base area of a pyramid.

You are 5 feet 4 inches tall and cast a shadow 3 feet long. At the same time, a nearby water tower casts a shadow 74 feet 3 inches long.
a. Find the height of the water tower.
The height of the water tower is 132 feet
How to solve for the height of the towerWe have the height to be 5 feet 4 inches
then 1 feet = 12 inches
inch = 1 / 12 ft
Then 4 inches = 1 / 12 x 4
= 1 / 3 ft
Height = 5 1/3
= 16 / 3
height of the shadow cast = 3 feet
For the water tank
74 ft 3 inches
= 74 x 3 / 12
297 / 4
the height of the tower
[tex]\frac{height of person}{height of shadow} =\frac{height of tower}{height of person}[/tex]
= [tex]\frac{16/3}{3} =\frac{x}{297/4} \\\\\frac{16}{3*3} =\frac{4x}{297}[/tex]
Then x = 132
Therefore the height of the water tower is 132 feet

The given equation solved for z is z = s/(r - 6c⁴)
Solving linear equationsFrom the questions, we are to solve the given equation for the specified value
The given equation is
s = zr - 6zc⁴
The specified value is z.
Thus, we are to solve for z.
Solving for z
s = zr - 6zc⁴
First, factor out z
s = z(r - 6c⁴)
Now, divide both sides by r - 6c⁴
s/(r - 6c⁴) = z(r - 6c⁴)/r - 6c⁴
s/(r - 6c⁴) = z
∴ z = s/(r - 6c⁴)

The end behavior of the second graph is that as x → ∞, f(x) → -∞ and x → -∞, f(x) → -∞
What is the Asymptote of the graph?An asymptote is defined as a line that a curve approaches, as it heads towards infinity. There are three types of Asymptotes namely horizontal, vertical and oblique.
It is called a Horizontal Asymptote when as x goes to positive or negative infinity the curve approaches some constant value.
It is called a Vertical Asymptote when as x approaches some constant value (from the left or right) then the curve goes towards positive or negative infinity
It is called an Oblique Asymptote when as x goes to positive or negative infinity, then the curve goes towards a line y = mx + b
Thus, the asymptotes of the graph are vertical asymptotes as;

When a data collection is ranked from least to greatest, the median is the midpoint. The number that appears most frequently in a data collection is called the mode.
The median is computed by sorting the scores into numerical order, dividing the total by 2, rounding the result up if the number of scores is odd to determine the median position, or by averaging the median position and the position after it, if the number of scores is even.

According to Descartes's rule of sign, how many possible positive and negative roots are there for the equation 0=−8x10−2x7+8x4−4x2−1?
Drag the choices to the boxes to correctly complete the table.
According to Descartes' rule of sign,
a. We have 0 or 2 real positive roots for the equation and
b. We have 0 or 2 real negative roots for the equation.
What is Descartes'rule of sign?Descartes' rule of sign states that
The number of real positive zero of a polynomial f(x) is the number of sign changes of the coefficients of f(x) or an even number less than the number of sign changes of the coefficients of f(x)The number of real negative zero of a polynomial f(x) is the number of sign changes of the coefficients of f(-x) or an even number less than the number of sign changes of the coefficients of f(-x)How to find the number of possible positive and negative roots are there for the equation?Since we have the equation 0 = −8x¹⁰ − 2x⁷ + 8x⁴ − 4x² − 1, we now re-write it as a polynomial function. So, it is now f(x) = −8x¹⁰ − 2x⁷ + 8x⁴ − 4x² − 1
a. What are the number of positive rootsTo find the number of positive roots, we require the number of sign changes of the polynomial f(x).
Thus, f(x) = −8x¹⁰ − 2x⁷ + 8x⁴ − 4x² − 1
Thus, the coefficients of f(x) are -8, -2, + 8, -4, -1, and we see that there are two sign changes from -2 to + 8 and from + 8 to -4.
Thus, there are 2 or 2 - 2 = 0 real positive roots.
Thus, we have 0 or 2 real positive roots for the equation.
b. What are the number of negative rootsTo find the number of negative roots, we thus need to find the number of sign changes of the polynomial f(-x).
Thus, f(-x) = −8(-x)¹⁰ − 2(-x)⁷ + 8(-x)⁴ − 4(-x)² − 1
= −8x¹⁰ + 2x⁷ + 8x⁴ − 4x² − 1
Thus, the coefficients of f-(x) are -8, +2, + 8, -4, -1. We see that there are two sign changes from -8 to + 2 and from + 8 to -4.
Thus, there are 2 or 2 - 2 = 0 real negative roots.
Thus, there are 0 or 2 real negative roots for the equation.
Thus,
We have 0 or 2 real positive roots for the equation andWe have are 0 or 2 real negative roots for the equation.Learn more about Descartes' rule of sign here:

What is consecutive integers?Whole numbers that followed each other with no gaps are known as consecutive integers. For example, the numbers 15, 16, and 17 are all consecutive integers. If is an integer, then the following consecutive integers begin at:,, and so on.
According to the given data:A divider counting argument can be employed because each member of the subgroups must be at least two apart.
We select no more than four numbers first from set 1,2,3,4,5,6,7,8,9,10,11,12. Let's use balls to represent these numbers. There are least two dividers between each of the balls.
So for example, o | | o | | o | | o | | represents {1,4,7,10}.
There must be 2(k - 1) dividers between both the balls in subsets of size k, leaving 12 - k - 2(k - 1) = 12 - 3k + 2 dividers to be placed at k + 1 spots between the balls.
[tex]\left(\begin{array}{c}(12-3 k+2)+(k+1)-1 \\k\end{array}\right)=\left(\begin{array}{c}12-2 k+2 \\k\end{array}\right)[/tex]

The equation [tex]d=50+20w[/tex] represents the relationship between dollar amount in her bank account and the number of weeks of savings.
The definition of an equation is a formula that states that two formulas are equal. For example, 3x + 5 = 14 is an equation where 3x + 5 and 14 are two terms separated by an equal sign. The most basic and simple algebraic equations consist of one or more variables in mathematics. In mathematics, a graph can be defined as a graphical representation or chart that systematically represents data or values. A point on a graph often represents a relationship between two or more things.

Answer:
L = 8
w = 3
Step-by-step explanation:
Givens
w = L - 5
L = x
Area = 24
Formula
Area = L * w
Solution
Area = (x) * (x - 5)
24 = x * (x - 5) Remove the brackets
24 = x^2 - 5x Subtract 24 from both sides
0 = x^2 - 5x - 24 This will factor
0 = (x - 8)(x + 3)
x + 3 is an extraneous root. You cannot have a length of -3 units no matter what the units are.
x - 8 = 0
