Answer:
The volume of the given pyramid is 300 cm³
Step-by-step explanation:
The volume of a pyramid, [tex]V_{pyramid}[/tex], is given as follows;
[tex]V_{pyramid} = \dfrac{1}{3} \times Base \ area \times Height[/tex]
The height of the pyramid = 12 cm
The side length of the square base of the pyramid = 5 cm
The base area of the pyramid polyhedron with square base = 5 cm × 5 cm = 25 cm²
Therefore, by substitution, we have;
[tex]V_{pyramid} = \dfrac{1}{3} \times 25 \ cm^2 \times 12 \ cm = 300 \ cm^3[/tex]
The volume of the given pyramid, V = 300 cm³.

Which expression represents
the area of a rectangle with
sides measuring 7x4y2z units and
2xy5z14?
Answers
______________________________
1.) To solve this you must first know the formula for area of a rectangle:Area [tex]=\sf{H}[/tex] × [tex]\sf{W}[/tex]Area [tex]=7x^4y^2z[/tex] × [tex]2xy^5z^{14}[/tex]Note:
- It doesn't matter which measurement fills the height or width part in the formula.
Equation at the end of Step 1:
[tex]7x^4y^2z[/tex] × [tex]2xy^5z^{14}[/tex][tex]2xy^5z^{14}[/tex] × [tex]7x^4y^2z[/tex]2.) Add 4 and 1, (x powers:)[tex]x^4+x=x^5[/tex]Note:
- To multiply powers of the same base, you can add their exponents. So you just do [tex]4+1=5[/tex].
- When you have a plain variable like [tex]x[/tex], you can assume [tex]x=1[/tex].
Equation at the end of Step 2:
[tex]7x^5y^2z[/tex] × [tex]2y^5z^{14}[/tex]3.) Add 2 and 5, (y powers:)[tex]y^2+y^5=y^7[/tex]Note:
- To multiply powers of the same base, you can add their exponents. So you just do [tex]2+5=7[/tex].
Equation at the end of Step 3:
[tex]7x^5y^7z[/tex] × [tex]2z^{14}[/tex]4.) Add 1 and 14, (z powers:)[tex]z+z^{14}=z^{15}[/tex]Note:
- To multiply powers of the same base, you can add their exponents. So you just do [tex]1+14=15[/tex].
- When you have a plain variable like [tex]z[/tex], you can assume [tex]z=1[/tex].
Equation at the end of Step 4:
[tex]7x^5y^7z^{15}[/tex] × [tex]2[/tex]5.) Multiply 7 and 2:[tex]7[/tex] × [tex]2=14[/tex]Note:
- Since we combine all the powers and multiplied the bases, all you have to do is put it all together in 1 form like we were doing after we added powers in the earlier steps.

horizontal, i and j are the unit vectors horizontally and vertically upwards respectively. The point
A is 0.8 m vertically above the point 0, which is on horizontal ground.
The ball takes 4 seconds to travel from A to B, where B is on the ground and OB = 64 m, as
shown in the diagram. By modelling the motion of the ball as that of a particle moving freely under gravity,

What are the measure of reference angles according to quadrats?We have I, II, III, IV quadrants.
In quadrant I the referece angle Ф is Ф.
In quadrant II the referece angle Ф is (π - Ф).
In quadrant III the referece angle Ф is (π + Ф).
In quadrant IV the referece angle Ф is (2π - Ф).
We know π is equal to 180°.
The conversion of radian to degrees is we multiply the radian value by 180°/π.
Given, The radian measure is 5π.
Therefore, the equivalent degree measure is,
= (5π)×(180/π).
= (5×180)°.
= 900°.

What is the equation of the line that passes through (1, 2) and (8,9) in slope-intercept form?
Answers
Answer:
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]
Step-by-step explanation:
The slope-intercept form of line is given by the formula:
[tex]y = mx+b[/tex]
Here m is the slope and b is the y intercept
Given
[tex](x_1,y_1) = (1,2)\\(x_2,y_2) = (8,9)[/tex]
First of all, the slope has to be found
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{9-2}{8-1}\\m = 1[/tex]
Putting m=1 in the equation
[tex]y = x+b[/tex]
Putting the point (1,2) in the equation to find the value of b
[tex]2 = 1+b\\b = 2-1\\b = 1[/tex]
The equation is:
[tex]y = x+1[/tex]
Hence,
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]

Answers
Answer: the answer is C 52
Step-by-step explanation:
The length of the fencing needed is given by the lengths of the lines
that goes around the space she wants to fence shown in the graph.
Correct response:
The amount of fencing the homeowner needs is; 38 + 10·√2Methods used to find the length of fencing neededThe coordinates of the vertices of the fenced area are presented as
follows;
A(-7, 7), B(4, 7), C(6, -7), and D(-7, -7)
Therefore, by finding the distance between the given points, we have;
Length of AB = 4 - (-7) = 11
Length of AD = 7 - (-7) = 14
Length of CD = 6 - (-7) = 13
Length of BC = √((6 - 4)² + (-7 - 7)²) = [tex]\sqrt{200}[/tex] = 10·√2
Length of fencing needed, L = AB + AD + CD + BC
Which gives;
L = 11 + 14 + 13 + 10·√2 = 38 + 10·√2
The length of fencing needed, L = 38 + 10·√2Learn more about the distance between points given the coordinates here:
