A pyramid is a solid shape with a specified shaped base. The required answer is 8.67 cubic feet.
A pyramid is a solid shape with a specified shaped base. While a square based pyramid is a type of pyramid which has its base to be a square.
Volume of a square based pyramid = [tex]\frac{1}{3}[/tex] x base area x height
Also, are of a square = length x length
So that,
i. For the first pyramid;
volume = [tex]\frac{1}{3}[/tex] x (2 x 2) x 6
= 8 cubic feet
The volume of the first pyramid is 8 cubic feet.
ii. For the second pyramid, we have;
height = 8 feet
base side = 2.5 feet
So that.
Volume = [tex]\frac{1}{3}[/tex] x (2.5 x 2.5) x 8
= 16.6667
Volume = 16.67 cubic meters
The volume of the second pyramid is 16.67 cubic meters.
Therefore, the volume of the second pyramid is greater than the volume of the first pyramid by;
volume of the second pyramid - volume of the first pyramid = 16.67 - 8.0
= 8.67 cubic feet

What is the solution to this system of equations? 2x+y=40 x-2y=-20
Answer: the solution to the system of equations is x = 12 and y = 16.
Step-by-step explanation: To solve this system of equations, you can use the method of substitution.
First, solve one of the equations for one of the variables. For example, you can solve the first equation for x:
2x + y = 40
2x = 40 - y
x = (40 - y)/2
Then, substitute this expression for x in the second equation:
x - 2y = -20
(40 - y)/2 - 2y = -20
Multiplying both sides by 2, we get:
40 - y - 4y = -40
-5y = -80
y = 16
Substituting this value for y in the first equation, we can solve for x:
2x + 16 = 40
2x = 24
x = 12
Therefore, the solution to the system of equations is x = 12 and y = 16.

A work ladder can extend to 8 meters. How many centimeters is that? How many kilometers is that? Use 1000 m) unit analysis to solve this conversion problem (1 km ==
Answer:
8m = 800cm
8m = 0.008km
Step-by-step explanation:
1 kilometer is 1000 meters
1 meter is 100 centimeters
You'd only have to multiply in the first one:
[tex]8 \times 100 = 800[/tex]
8m = 800cm
Remember that when multiplying by 100 you only have to add zeros.
For km, as it is bigger than m you have to divide by 1000, when dividing this time you only have to carry an imaginary point starting from right to left, the amount of zeros there are:
[tex]8. \\ .8 \\ .08 \\ .008 \\ 8 \div 1000 = .008[/tex]
8m = 0.008km
If you run out of numbers when carrying the point, just add zeros.

The image after the transformations of rotation, translation or reflection can be found by certain operation or rotation.
We can find how to know the image of certain figures after the given transformations are done.
91) Here it is translation.
x coordinates are shifted to right by 3 units and y coordinates are shifted to down by 5 units.
So the entire graph will be shifted to right by 3 units and down by 5 units.
92) Here, the translation is by not shifting the x coordinates and shifting the y coordinates 2 units to the down.
So the entire graph will be shifted to down by 2 units.
93) When a graph is reflected across x = -2, then the graph is moved horizontally such that the original figure and the image will be at the same distance from x = -2.
94) When a graph is reflected across y = 1, then the graph is moved vertically such that the original figure and the image will be at the same distance from y = 1.
95) When a graph is rotated about the origin 180°, if it is clockwise or anticlockwise, each of the coordinates (x, y) in the graph will become (-x, -y).

simultaneous equations x+5y=6
x+3y=2
Answer:
(- 4, 2 )
Step-by-step explanation:
x + 5y = 6 → (1)
x + 3y = 2 → (2)
subtract (2) from (1) term by term to eliminate x
(x - x) + (5y - 3y) = 6 - 2
0 + 2y = 4
2y = 4 ( divide both sides by 2 )
y = 2
substitute y = 2 into either of the 2 equations and solve for x
substituting into (1)
x + 5(2) = 6
x + 10 = 6 ( subtract 10 from both sides )
x = - 4
solution is (- 4, 2 )

±1/2, ±1, ±7 are the possible rational roots of the polynomial function.
What is the rational root theorem?The rational root theorem, also known as the rational root test, is an algebraic theorem that states that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, both the constant term (the term without a variable) and the leading coefficient (the coefficient of the highest power) must be divisible by the fraction's denominator.
An anXn+ an− 1xn − 1 + … + a1x1 + a0 = 0 is a polynomial equation in one variable (x), where a0, a1,..., and an are regular integers. Therefore, q must divide a and p must divide a0 for a polynomial equation to have a rational solution, p/q.
It is given in the question,
F(x)=2x^2-3x+7
Here, p is a 7-fold factor.
p, thus, might have a value of 1, -1, 7, or -7.
and q is a two-fold factor.
Thus, q might have a value of 1, -1, 2, or -2.

A recipe calls for 3/2 cups of flour. You only have a 1/2 cup measuring cup. What fraction of a cup of flour, in halves, do you need?
To obtain an amount of 3 / 2 cups of flour, then we need three halves of cup by means of a 1 / 2 cup measuring cup.
How many cups are needed to get the require amount of flour
In this problem we have the case of recipe that requires 3 / 2 cups of flour in terms of certain number of measuring cups with an amount of 1 / 2 cups. The number of measuring cups (n) is equal to the total required by the recipe (M) divided by the amount of the measuring cup (m), both in cups. That is:
n = M / m
If we know that m = 1 / 2 cup and M = 3 / 2 cup, then the number of measuring cups is:
n = (3 / 2 cup) / (1 / 2 cup)
n = 3
In other words, we need 3 halves of a cup of flour to obtain the required amount of 3 / 2 cups.

Tiger understands that this is a straight line equation. Typically, this equation is expressed as y=mx+b (or "y=mx+c" in the UK).
A straight line drawn using the Cartesian coordinate system has the formula "y=mx+b," where "y" denotes the vertical axis and "x" denotes the horizontal axis.
In this equation, y represents how high the line rises, x represents how far it travels along, m represents the slope or gradient, or how steep the line is, and b represents the Y-intercept, or the point at which the line crosses the Y axis.
The X, Y, and slope are collectively referred to as the line properties. We will now plot the line 5x-6y-42 = 0 and determine its characteristics.
x = 0 the value of y is 7/-1 so this line "cuts" the y axis at y=-7.00000
y-intercept = 42/-6 = 7/-1 = -7.00000
y = 0 the value of x is 42/5 Our line therefore "cuts" the x axis at x= 8.40000

m∠5 = 56°
m∠6 = 32°
What is triangle?Depending on how many sides a polygon has, it is given a unique name. Because "tri" is a word that indicates "three," the polygon with three sides is known as a triangle. This polygon has three angles, as indicated by its name. Poly means numerous in the prefix.
Three vertices make up a triangle, a three-sided polygon. The triangle's angles are formed at a point where the three sides are joined end to end. The triangle's three angles add up to a total of 180 degrees.
In the given problem,
m∠6 = 180° - (90° + 58°)
so, m∠6 = 32°
Next, m∠1 +m∠6 = 180° - (42° +34°)
= 104°
so, m∠1 = 104° - 32°
= 72°
Next, m∠5 = 90° - 34°
m∠5 = 56°
Again, m∠4 = 180° - (56° + 58°)
m∠4 = 66°
Now from the figure, m∠3 and m∠4 are vertically opposite angle.
So, m∠3 = 66°
Again, m∠2 = 180° - 66° = 114°

f’’(x)=cos(x), f’(pi)=2, f(pi)=-1
f(x)=?
PLS URGENT
The required function f(x) is represented by -1 + F(x + sin(x)).
To find the function f(x), you can use the formula for integration by substitution:
f(x) = F(g(x)) + C
where F is an antiderivative of f, g is a function such that g'(x) = f(x), and C is a constant.
In this case, we can take g(x) = x + sin(x). Then g'(x) = cos(x), so f(x) = F(g(x)) + C = F(x + sin(x)) + C.
We are given that f'(π) = 2 and f(π) = -1, so we can use these values to find the constants C and F.
First, we can find F by taking the derivative of F(x + sin(x)). This gives us:
F'(x + sin(x)) = f(x) = cos(x)
Substituting x = π and using the fact that F'(x + sin(x)) = f'(π) = 2, we get:
F'(π + sin(π)) = 2
Since sin(π) = 0, this simplifies to:
F'(π) = 2
Then, using the fact that F(x + sin(x)) = f(π) = -1 when x = π, we can find the value of F(π):
F(π) = -1
Now that we have found the values of F and F', we can use these to find the value of C.
Since F(x + sin(x)) = F(x) + F'(x) sin(x), we can substitute x = π to get:
F(π + sin(π)) = F(π) + F'(π) * sin(π)
Substituting the values we found above, this becomes:
F(π + 0) = -1 + 2 x 0
Which simplifies to:
F(π) = -1
Since F(π) = -1, we can conclude that C = -1.
Therefore, the function f(x) is given by:
f(x) = F(x + sin(x)) + C = F(x + sin(x)) - 1
= -1 + F(x + sin(x))
