Answer:
Below
Step-by-step explanation:
First find the value of the common vertical side
12/v = v/16
v^2 = 192
v = 8 sqrt 3
Now use pyhtag theorem to find x and y
y^2 = 12 ^2 + (8 sqrt3)^2
y = sqrt (336) = 4 sqrt (21)
now find x the same way
x^2 = 16^2 + (8 sqrt(3))^2 = 448
x = sqrt (448 ) = 8 sqrt 7

What is the angle?
An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
Given that m∠EBF = 60°, m∠EBG = 2m∠EBF
The m∠EBF is the sum of the angles and the angles are m∠EBG and m∠EBF.
Therefore,
m∠EBF = m∠EBG + m∠EBF
Putting m∠EBF = 60° and m∠EBG = 2m∠EBF in aboue equation:
60° = 2m∠EBF + m∠EBF
3m∠EBF = 60°
Divide both sides by 3:
∠EBF = 20°.
12.
Given that, m∠ABE = 64°.
From the diagram, m∠ABD = m∠DBE.
The m∠ABE is the sum of the angles and the angles are m∠ABD and m∠DBE.
m∠ABE = m∠ABD + m∠DBE
64° = 2m∠DBE
Divide both sides by 2:
m∠DBE = 32°

Find the slope of the line that passes through G(−3, 2) and H(7, 2) .
Answer:
The slope of the line that passes through G(-3, 2) and H(7, 2) is 0.
Step-by-step explanation:
The slope of a line can be found using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
In this case, we have two points G(-3, 2) and H(7, 2):
m = (2 - 2) / (7 - (-3))
m = 0
Therefore, the slope of the line that passes through G(-3, 2) and H(7, 2) is 0.

solve the equation z2 z 1 = 0 for z = (x,y) by writing (x,y)(x,y) (x,y) (1,0) = (0,0)
The solutions of x = 0 or x = y and y = 0 or y = 1 can then be found. Therefore, the solutions of the equation are (0,0), (0,1), (1,0), and (1,1).
x2 - xy + y2 - x = 0
x(x - y) + y(y - 1) = 0
x(x - y) = 0 and y(y - 1) = 0
x = 0 or x = y and y = 0 or y = 1
Therefore, the solutions are (0,0), (0,1), (1,0), and (1,1).
The equation z2 z 1 = 0, when written as (x,y)(x,y) (x,y) (1,0) = (0,0), can be manipulated to x2 - xy + y2 - x = 0. By factoring out the x and y terms, the equation can be rearranged to x(x - y) + y(y - 1) = 0. This then can be further simplified to x(x - y) = 0 and y(y - 1) = 0. The solutions of x = 0 or x = y and y = 0 or y = 1 can then be found. Therefore, the solutions of the equation are (0,0), (0,1), (1,0), and (1,1).

006 (part 1 of 2) 10. 0 points consider two conductors 1 and 2 made of the same ohmic material; i. E. , rho1 = rho2. Denote the length by ℓ, the cross sectional area by
a. The same voltage v is applied across the ends of both conductors and the field e is inside of the conductor. V1 ~e1 i1 ℓ1 r1 b v2 ~e2 i2 ℓ2 r2 b if a2 = 2 a1 , ℓ2 = 2 ℓ1 and v2 = v1 , find the ratio e2 e1 of the electric fields. 1. E2 e1 = 1 8 2. E2 e1 = 8 3. E2 e1 = 1 12 bancroft (acb3943) – hw03 – lai – (55310) 2 4. E2 e1 = 4 5. E2 e1 = 1 2 6. E2 e1 = 1 7. E2 e1 = 1 3 8. E2 e1 = 1 16 9. E2 e1 = 1 4 10. E2 e1 = 2
Ohm's Law states that the current passing through a conductor is proportional to the voltage across the conductor, and inversely proportional to the resistance of the conductor.
Mathematically, this can be expressed as:
V = IR,
where V is the voltage, I is the current, and R is the resistance of the conductor. The resistance of a conductor is given by:
R = ρℓ/a,
where ρ is the resistivity of the material, ℓ is the length of the conductor, and a is the cross-sectional area.
From Ohm's Law, we can also derive an expression for the electric field inside the conductor:
E = V/ℓ = IR/ℓ = ρI/a
In the case of conductors 1 and 2, the voltage across both conductors is the same (v2 = v1), so the electric field in conductor 2 can be expressed as:
E2 = V2/ℓ2 = v1/(2ℓ1) = ρI2/a2 = (ρ/2a1)I2
Similarly, the electric field in conductor 1 can be expressed as:
E1 = V1/ℓ1 = v1/ℓ1 = ρI1/a1 = (ρ/a1)I1
Finally, the ratio of the electric fields in conductors 1 and 2 can be calculated as:
E2/E1 = (ρ/2a1)I2 / (ρ/a1)I1 = a1/2a1 = 1/2
So, the ratio of the electric fields, E2/E1, is equal to 1/2. This means that the electric field in conductor 2 is half the electric field in conductor 1, despite the fact that the voltage across both conductors is the same. This happens because the cross-sectional area of conductor 2 is twice that of conductor 1, which compensates for the fact that the length of conductor 2 is also twice that of conductor 1.

a. squares with sides of length x are cut out of each corner of a rectangular piece of cardboard measuring 3 ft by 4 ft. the resulting piece of cardboard is then folded into a box without a lid. find the volume of the largest box that can be formed in this way.
The largest box that can be formed has a volume of 20 cubic feet.
Let's call the side length of the square cutout x. The original piece of cardboard measures 3 feet by 4 feet, so the dimensions of the piece of cardboard after the cutouts are made are (3 - 2x) by (4 - 2x).
When this piece is folded into a box, the length and width of the box will be (3 - 2x) and (4 - 2x) respectively. The height of the box will be x, as that is the height of the cutout squares.
The volume of the box can be found by multiplying the length, width, and height: V = (3 - 2x)(4 - 2x)x
We want to find the maximum volume, so we need to differentiate the expression for the volume and set it equal to zero, and then solve for x.
dV/dx = 2x(4 - 2x) - (3 - 2x)(2x) = 0
2x(4 - 2x) = (3 - 2x)(2x)
2x(4 - 2x) = 2x^2 - 6x^2
-4x^2 + 4x = 0
x(4 - x) = 0
x = 0 or x = 4
Since the side length of the cutout square cannot be negative, we reject x = 0 and keep x = 4. So, the maximum volume will occur when the side length of the cutout squares is 4 feet.
Substituting x = 4 into the expression for the volume, we find:
V = (3 - 2x)(4 - 2x)x = (3 - 2x)(4 - 2x) = (3 - 2x)(4 - 2x) = (3 - 8)(4 - 8) = -5 * -4 = 20 cubic feet
So, the largest box that can be formed has a volume of 20 cubic feet.

The angle of depression is 32°.
What is the depression's angle?
The angle of depression is the angle formed when the item being seen is below the observer's level between the horizontal line and the line of sight of the observer.
The angle of depression is the angle formed by the horizontal axis and the downward axis of a line of sight. As an example, if you were perched on top of a hill or other structure and looked down at an object, you might determine the angle of depression. To measure these angles, a theodolite or a clinometer can be used. The maximum depression angle is 90 degrees. It can't be possible because any rational spectator would turn around the instant the object passed beneath him.
Due to the fact that AB is perpendicular to B and AD is the horizontal line of sight, we can conclude that AD AB (given).
∴ ∠DAB = 90°.
We can express this as DAB = DAC + BAC.
alternatively, 90° = ∠DAC + 58°

The use of a logarithm can be utilised to solve issues that cannot be resolved using the concept of exponents alone. A logarithm is simply another way to describe exponents. Log interpretation is not that tough. It suffices to know that an exponential equation can also be written as a logarithmic equation in order to comprehend logarithms.
Exponent and logarithm are inverses of one another. This is explained in the section below. John Napier, a mathematician, first developed logarithms as a technique to perform computations simply, and other scientists, engineers, etc. immediately embraced this idea.
The given logarithmic equation is:
log ([tex]y^{7}xz^{3}[/tex])
Now, we can use the properties of logarithms to expand this fully.
log (abc) = log a + log b+ log cTherefore,
log ([tex]y^{7}xz^{3}[/tex]) = log ([tex]y^{7}[/tex]) + log (x) + log ([tex]z^{3}[/tex])

Therefore, the area of the wall to be painted will exclude the window and the door.
Hence,
area of wall of the wall to be painted = area of the wall - area of the window - area of the door
Therefore,
area of wall of the wall to be painted = 10² - (1 × 0.5) - (2 × 1)
area of wall of the wall to be painted = 100 - 0.5 - 2
area of wall of the wall to be painted = 97.5 metres²
Therefore,
1 metres square = Rs0.5
97.5 metres squared = ?
cross multiply
cost to paint the wall = 0.5 × 97.5
cost to paint the wall = Rs.48.75

Ted says that the triangle below cannot be classified because all sides are different lengths. Is Ted correct? Explain why or why not.
Answer:
he is not because triangles can be different sides but they always have to equal 180 if it's a right triangle but if it does not it's a ln acute or obtuse triangle
a group of eight kids lines up in random order. each ordering of the kids is equally likely. there are five girls and three boys in the group. what is the probability that all the boys are ahead of all the girls?
Using the arrangements formula, it is found that there is a 0.0178 = 1.78% probability that all the girls are ahead of all the boys.
The number of possible arrangements of the n elements is the factorial of n, that is:
[tex]A_{n} = n![/tex]
The total number of outcomes is the arrangement of 8 elements, hence:
T = 8! = 40320
The desired number of outcomes is all-girls(5!), then all-boys(3!), hence:
D = 5! × 3! =120× 6=720
Hence, the probability is:
p = D/T =720/40320 = 0.0178
There is a 0.0178 = 1.78% probability that all the girls are ahead of all the boys.
