In the square pyramid shown below, the slant height is 12 centimeters and the height of the pyramid is 7 centimeters.
To the nearest whole number, find the diagonal length of the base of the pyramid. In your final answer, include your calculations with reasoning for each step.
Answers
The diagonal of the square pyramid will be equal to 33.10 centimetres.
What is diagonal?The lines which connect the two opposite corners of any quadrilateral are called diagonal. here we have a square pyramid whose slant height and the vertex height are given and we have to find the diagonal length of the base.
Let the side of the square base of the pyramid is "a". Now the side will be calculated by the following relation.
[tex](\dfrac{a}{2})^2[/tex] = s² - H
[tex](\dfrac{a}{2})^2[/tex] = 12² - 7 = 137
a² = 137 x 4 = 548
a = √548 = 23.40 cm
Now the diagonal will be calculated by using the Pythagorean theorem
D² = 23.04² + 23.40²
D² = 548 + 548
D = √1096
D = 33.10 centimeter
Therefore the diagonal of the square pyramid will be equal to 33.10 centimetres.

Determine which sequences of transformations could be applied to the parent function f(x) = x to obtain the graph of g.
Answers
Answer:
Reflect over the y-axis, vertically stretch by a factor of 3, and then shift down 1 unit
Step-by-step explanation:
Parent function: [tex]f(x)=x[/tex]
The graph of the parent function is a straight line graph that intersects the axes at the origin (0, 0) and has a positive slope of 1 unit.
To determine the sequence of transformations, find the equation of the transformed function in slope--intercept form.
Slope-intercept form of a linear function: [tex]f(x)=mx+b[/tex]
(where m is the slope and b is the y-intercept)
To calculate the slope of the transformed function, choose two points on the line and use the slope formula:
Let (x₁, y₁) = (0, -1)Let (x₂, y₂) = (1, -4)[tex]\implies \sf slope\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-4-(-1)}{1-0}=-3[/tex]
The y-intercept (where the line crosses the y-axis) of the transformed function is (0, -1).
Therefore the equation of the transformed function is:
[tex]g(x)=-3x-1[/tex]

[tex]y=f(ax) \implies f(x) \: \textsf{stretched parallel to the x-axis (horizontally) by a factor of} \: \dfrac{1}{a}[/tex]

Answer:
See below ~
Step-by-step explanation:
a) Forming the equation :
⇒ We start with a number, x
⇒ Now we double it so : 2(x) = 2x
⇒ Then we add 11 to it : 2x + (11) = 2x + 11
⇒ It is equal to 25 : 2x + 11 = 25
b) Solving the equation :
Subtract 11 from both sides :
⇒ 2x + 11 - 11 = 25 - 11
⇒ 2x = 14
Divide 2 on both sides :
⇒ 2x/2 = 14/2
⇒ x = 7

please help
Answers
Answer:
18
Step-by-step explanation:
We know that y is 1.5 times x, so when x = 12, y = (1.5)(12)=18
This directly proportional relationship between p and q is written as p∝q where that middle sign is the sign of proportionality. The value of x is 8, when the value of y is 12.
What is the directly proportional and inversely proportional relationship?Let there are two variables p and q
Then, p and q are said to be directly proportional to each other if
p = kq
where k is some constant number called the constant of proportionality.
This directly proportional relationship between p and q is written as p∝q where that middle sign is the sign of proportionality.
In a directly proportional relationship, increasing one variable will increase another.
Now let m and n be two variables.
Then m and n are said to be inversely proportional to each other if
[tex]m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}[/tex]
(both are equal)
where c is a constant number called the constant of proportionality.
This inversely proportional relationship is denoted by
[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]
As visible, increasing one variable will decrease the other variable if both are inversely proportional.
Given Variables y and x have a proportional relationship, therefore, we can write,
y ∝ x
y = k × x
21 = k × 14
21/14 = k
k = 1.5
Therefore, the equation for the relationship between x and y can be written as,
y = 1.5x
now, the value of x when the value of y is 12 is,
12 = 1.5 × x
x = 8
Hence, the value of x is 8, when the value of y is 12.

Which inequality is shown in this graph?
OA. ys-3x+3
OB. y2-3x+3
OC. ys 3x+3
OD. y23x+3
Answers
Answer:
A
Step-by-step explanation:
The line is shaded below, so we can eliminate B and D.
Also, the line has negative slope, so this eliminates C.
The inequality of the graph is y ≤ -3x + 3.
The correct option is A.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
The inequality graph has two points on the line (0, 2) and (2, -3).
And the shaded region of the graph is left to the line made by points (0, 2) and (2, -3).
The line passing through the points (0,2) and (2,-3) can be written in a slope-intercept form as:
y = mx + b
where m is the slope and b is the y-intercept.
The slope of the line is given by:
m = (y2 - y1) / (x2 - x1) = (-3 - 2) / (2 - 0) = -5/2
The y-intercept can be found by substituting the coordinates of either point into the equation:
y = mx + b
2 = (-5/2)(0) + b
b = 2
So the equation of the line is:
y = (-5/2)x + 2
The shaded region of the graph is to the left of this line. Since the line has a negative slope, any point below the line will satisfy the inequality y ≤ -3x + 3. Therefore, the correct answer is A.

Answers
The complete question is
"Which is the graph of the system x + 3y > –3 and y < One-halfx + 1?"
The solution is the intersection region of all the solutions in the system of inequalities.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
We know that the lines are given as;
x + 3y = -3
y = 1/2 x + 1
Solving for "y" from the first line;
3y = -3 - x
y = -1 - x/3
For the line x + 3y = -3 the x-intercepts;
y = 0
y = -1 - x/3
0 = -1 - x/3
x/3 = -1
x = -3
And the y-intercept;
y = -1
For the line y = 1/2 x + 1 the x-intercepts;
y = 0
0= 1/2 x + 1
1/2x = -1
x = -2
And the y-intercept
x = 0
y = 1
Now we can graph both lines,

Hello!
We are going to evaluate the expression with our given x-value for question 2.
We know that our expression is: x^4 + 5x^3 - 3x^2 + 11x - 6
We also know that our x-value = 3
We will simply plug in "3" to "x" in our expression and solve.
Solve:
x^4 + 5x^3 - 3x^2 + 11x - 6
Plug in 3 to x:
(3)^4 + 5(3)^3 - 3(3)^2 + 11(3) - 6
Simplify:
(3)^4 + 5(3)^3 - 3(3)^2 + 11(3) - 6
81 + 5(3)^3 - 3(3)^2 + 11(3) - 6
81 + 135 - 3(3)^2 + 11(3) - 6
81 + 135 - 27 + 33 - 6
