Notice, (5,0) and (-4,0), the y-coordinate is 0, namely those are x-intercepts, the vertex is halfway between them, namely the vertex is at 0.5 over the x-axis.
therefore the equation of the axis of symmetry will be the x = 0.5.
Answer:
C) AB = BC = CD = DA = 2√5
Step-by-step explanation:
Given
A(1, 4)
B(3, 0)
C(1, −4)
D(−1, 0)
We get the distance between point A and point B
AB = √((3-1)²+(0-4)²) = √20 = 2√5
BC = √((1-3)²+(-4-0)²) = √20 = 2√5
CD = √((-1-1)²+(0-(-4))²) = √20 = 2√5
DA = √((1-(-1))²+(4-0)²) = √20 = 2√5
C) AB = BC = CD = DA = 2√5
Answer: The bracelet she bought was $32.50
Step-by-step explanation: You can figure questions like these out by taking the total spent which is 42.50 and then subtracting the necklace cost from that to find the second amount spent. 42.50 - 10 = 32.50.
Hope this helps
Where is the rest? What are the following figures?
Answer:
If my friend is in 5th grade and they need an example on exponents I would show them something like this 7 to the 3 power would be equal to 7 times 7 times 7 which also equals 343 or 4 to the 4th power would be equal to 4 times 4 times 4 times 4 which equals 256
Step-by-step explanation:
This is a simpiler way to show a younger student how to figure out exponents also. Have a great day :D
