Blank 1: The Base Area (B) of the pyramid is _ cm2. --> Area = (1/2)ap
Blank 2: The height (h) of the pyramid is _ cm.
Blank 3: The Volume (V) of the pyramid is _ cm3.
Use the formula V = (1/3)Bh to find the volume of the hexagonal pyramid.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the dimensions of the hexagon are not given.
I will assume that:
[tex]b = 6[/tex] --- base length
[tex]h = 8[/tex] --- height
First, we calculate the height (a) of each triangle that makes the hexagonal base
The formula to use is:
[tex]a^2 = b^2 - (\frac{b}{2})^2[/tex]
[tex]a^2 = 6^2 - (\frac{6}{2})^2[/tex]
[tex]a^2 = 6^2 - (3)^2[/tex]
[tex]a^2 = 36 - 9[/tex]
[tex]a^2 = 27[/tex]
Take positive square roots
[tex]a = \sqrt{27[/tex]
Expand
[tex]a = \sqrt{9*3[/tex]
Split
[tex]a = \sqrt{9}*\sqrt3[/tex]
[tex]a = 3\sqrt3[/tex]
So, we have:
[tex]Area = \frac{1}{2}ap[/tex]
Where
[tex]a = 3\sqrt3[/tex]
[tex]p =perimeter[/tex]
[tex]p = 6 * b[/tex] ---- 6 represents the sides of the hexagon
[tex]p = 6 * 6[/tex]
[tex]p = 36[/tex]
[tex]B= \frac{1}{2}ap[/tex]
[tex]B= \frac{1}{2} * 3\sqrt 3 * 36[/tex]
[tex]B= 3\sqrt 3 *18[/tex]
[tex]B = 54\sqrt 3[/tex]
[tex]h = 8[/tex]
Lastly, the volume is:
[tex]V = \frac{1}{3}Bh[/tex]
So:
[tex]V = \frac{1}{3} * 54\sqrt3 * 8[/tex]
[tex]V = 18\sqrt3 * 8[/tex]
[tex]V = 144\sqrt3[/tex]
If g(x) = 2x + 1 and f (x) = x2 + 4, find g[f(4)].
g[f(4)] =
Answer:
g(f(4)) = 41
Step-by-step explanation:
Evaluate f(4) then substitute the value obtained into g(x)
f(4) = 4² + 4 = 16 + 4 = 20, then
g(20) = 2(20) + 1 = 40 + 1 = 41
That is g(f(4)) = 41
Find the Arc Length of AB (picture provided) and show work.
Circumference of a circle is pi x diameter
Circumference = 3.14 x 8 = 25.12 feet.
Arc AB is 45 degrees.
Arc length = circumference x angle/360
Arc length = 25.12 x 45/360 = 3.14 feet
Answer: 3.14 feet

Which type of transformation (reflection, rotation or translation) is most difficult for you to perform? Which is the easiest? Why do you think this is?
Answer:
Easiest: Translation
Most difficult: rotation
Step-by-step explanation:
- Translation involves just moving of an image without any changes anything about it from size to orientation to shape. Therefore, the translated image is exactly the same as the original one just that it is moved to a different place.
- Rotation involves rotating the image by a certain angle.
For example, we can rotate an image by 30°, 45°, 60° e.t.c.
- Reflection is simply the mirror image of an existing image which is basically flipping the original image along a vertical or horizontal line which acts like a mirror.
Looking at these definitions, the easiest will be translation because we are not changing any single thing but just moving from one place to another while the most difficult would be rotation because it involves rotating at an angle which one may not easily get correctly.

Two sides of a right triangle measure 777 units and 333 units.
Answer:
58 units squared
Step-by-step explanation:
**I'm doing the question with the 7 by 3 triangle in the picture, not 777 by 333**
Pythagorean Theorem: [tex]a^2+b^2=c^2[/tex], where c is the length of the hypotenuse.
The given sides are legs, therefore, [tex]3^2+7^2=c^2[/tex]
[tex]9+49=c^2; 58=c^2; c=\sqrt{58}[/tex]
c is also one of the sides of the square. A square's area is one of the sides' lengths squared, so:
[tex](\sqrt{58}) ^{2}=58[/tex]
Answer:
58
Step-by-step explanation:
We can use the Pythagorean theorem to find the area of the square for the third side.
The equation for the Pythagorean theorem is
a^2 + b^2 = c^2
where a and b are the lengths of the two legs of the triangle, and c is the length of the hypotenuse.
a^2 + b^2 = c^2
3^2+7^2=x^2
9+49=x^2
58=x^2
The area of the square for the third side of the triangle is 58 units^2 squared.

What are the answer please number which question you are answering
Answer:
7.
This is a complementary angle, which means that the two angles add up to 90 degrees. The two angles, in this case, are b and 52. Thus, we have:
b + 52 = 90
b = 38.
Therefore, b is 38 degrees.
8. This is a supplementary angle, which means that the two angles add up to 180 degrees. There is a right angle in the picture to confuse us, so we can just pretend that that doesn't exist, and just focus on the 180-degree angle (which is the straight line). The two angles shown are b and 117, so we have:
b + 117 = 180
b = 63
Therefore, b is 63 degrees.
9. This is a supplementary angle, which means that the two angles add up to 180 degrees. There is another line in the picture to confuse us, so we can just pretend that the line that is making a triangle (the one opposite of 125 degrees) doesn't exist, and just focus on the 180-degree angle (which is the straight line). The two angles shown are b and 125, so we have:
b + 125 = 180
b = 55
Therefore, b is 55 degrees.

Answer correctly please !!!! Will mark Brianliest !!!!!!!!!!!!!!
Answer:
Side Length AB = 22
Side Length CB = 35.21
Side Length = 41.52
Angle A = 58°
Angle B = 90°
Angle C = 32°
Step-by-step explanation:
Side Length CB;Tan(32) = 22 / CB
Tan(32) * CB = 22
CB = 22 / Tan(32)
CB = 35.21
Side Length AC; (Now that we know the Length of AB and BC)22² + 35.21² = AC²
484 + 1239.74 = AC²
1723.74 = AC²
[tex]\sqrt{1723.74}[/tex] = AC
41.52 = AC
Angle A (Since we know Angle B and Angle C)Angle A + Angle B + Angle C = 180°
Angle A + 32° + 90° = 180
Angle A + 122 = 180
Angle A = 180 - 122
Angle A = 58°
Hope this helps!
Answer:
Sine Rule will apply here too
22/Sin32° = AC/sin90
AC = 22sin90/sin32
AC=41.52(To the nearest 100th)
Angles in a triangle =180
Angle A = 180 - 90 - 32
Angel A = 58°
BC/Sin58 = 22/sin32
BC = 22sin58/sin32
BC=35.21 (Nearest 100th).
Have a great day!
