[6(x - 2)] (3x + 30) What is mZDHG? G Enter your answer in the box. 19
Answer:
[6(x - 2)]
= 6x-12
6x-12 = 3x+30 (reason: vertical angles)
3x-12 = 30
3x = 30+12
3x = 42
x = 14
m<DHG = 6x-12
= 6(14)-12
= 84-12
= 72
Therefore, m<DHG = 72°

Which event is an example of a physical change?
1. Iron rusting
2. Fireworks exploding
3. Eggs cooking
4.ice melting
Answer:
Ice melting
Step-by-step explanation:
Think about ice for a moment. After ice melts into liquid water, you can refreeze it into solid ice if the temperature drops. Freezing and melting are physical changes. The substances produced during chemical changes however cannot easily change back into the original substances.
The top of a ladder slides down a vertical wall at a rate of 0.25 m/s. At the moment when the bottom of the ladder is 5 m from the wall, it slides away from the wall at a rate of 0.6 m/s. How long is the ladder?
==================================================
Explanation:
L = length of ladder
Draw an xy axis. Focus on the upper right quadrant where x > 0 and y > 0
Let the origin (0,0) be the base of the wall.
Let y be the height of the top of the ladder and x be the horizontal distance the base of the ladder is from the base of the wall
Since the ladder is sliding down at a rate of 0.25 m/s, this means dy/dt = -0.25
At x = 5, we are given that dx/dt = 0.6
Use the pythagorean theorem to see that
a^2+b^2 = c^2
x^2 + y^2 = L^2
Now apply the derivative to both sides with respect to t. Don't forget to apply the chain rule while doing so.
d/dt[ x^2 + y^2 ] = d/dt[ L^2 ]
d/dt[ x^2 ] + d/dt[ y^2 ] = d/dt[ L^2 ]
2x*dx/dt + 2y*dy/dt = 0
2(x*dx/dt + y*dy/dt) = 0
x*dx/dt + y*dy/dt = 0
Note how the right hand side goes to 0 because the derivative of a constant is 0. The ladder length L doesn't change, so neither does L^2.
From here we plug in x = 5, dx/dt = 0.6, dy/dt = -0.25 and we solve for y
x*dx/dt + y*dy/dt = 0
5*0.6 + y*(-0.25) = 0
0.3 - 0.25y = 0
3 = 0.25y
0.25y = 3
y = 3/0.25
y = 12
The top of the ladder is y = 12 meters off the ground and the base is x = 5 meters from the wall.
Therefore,
L^2 = x^2 + y^2
L = sqrt(x^2 + y^2)
L = sqrt(5^2 + 12^2)
L = 13
The ladder is 13 meters long.

HELP PLEASE!!! Find y: -6y - 7 =29
Please give at least somewhat of an explanation because I am so confused and need help to understand.
Answer:
y = -6
Step-by-step explanation:
-6y + -7 = 29
+7 +7
-6y = 36
-6 -6
y = -6
Here's our original equation. We're trying to get y by itself, so we first subtract seven. (What you do to one side, you do to the other). That leaves us with -6y = 36. Next, let's divide both sides by -6. This leaves us with our final equation, y = -6. I really hope this helps!

Which is the correct algebraic representation of the transformation displayed on the graph?
A (y,-x)
B (-y,x)
C (-x,y)
D (-x,-y)
Answer:
Option (B)
Step-by-step explanation:
Let's check the relation in the given rectangles by selecting a point.
Let the point is E.
After transformation image of the point E becomes E'.
Coordinates of point E → (7, 6)
Coordinates of point E' → (-6, 7)
E(7, 6) → E'(-6, 7)
Rule for the transformation is,
(x, y) → (-y, x)
This rule is for the rotation of a point by 90° counterclockwise about the origin.
Therefore, Option (B) is the correct option.

Which is a longer distance: 23678 centimeters or 2.3678 kilometers? Explain how you know. Please help! I’ll give give Brainliest with explanation
Answer:
2.3678 kilometers
Step-by-step explanation:
1 km = 100,000 cm
2.3678 * 100,000 = 236, 780
236, 780 > 23,678
Answer:
2.3678 kilometers is longer.
Step-by-step explanation:
The rate of conversion is
10 millimeters = 1 centimeter
100 centimeters = 1 meter
1000 meters = 1 kilometer
Therefore, centimeters to kilometers would be 23678÷ (100× 1000): a smaller to a larger measurement would require division. This results in 0.23678 kilometers, which is shorter than 2.3678 kilometers.
Or, kilometers to centimeters would be, 2.3678 × (100× 1000): a larger to smaller measurement requires multiplication. This results in 236780 centimeters which is longer than 23678 centimeters.
Baseline is 2.3678 kilometers is longer than 23678 centimeters.
