First, coordinate Q is (-5,2) and Q' is (6,2). First, we know that this is a horizontal reflection becuase only the x-values change. This means that the line of reflection will be x=some value. I think the best way to go about this is to find the midpoint of Q and Q' using the formula: M=(x1+x2/2,y1+y2/2)
Q is the first point and Q' is the second point
M=(-5+6/2,2+2/2)
M=(1/2,4/2)
M=(1/2,2)
Since we know the y-values of Q, Q', and the midpoints are all 2, then the line of reflection would be x=1/2
Hope this helps
Answer: The tree is 27 feet tall.
Step-by-step explanation:
Here's what we know:
6/10 = x/45 (a 6 foot object creating a 10 shadow is equivalent to something else making a 45 shadow)
We need to isolate x. Multiply both sides by 45:
6*45/10 = x
We can factor out a 2:
3*45/5 = x
We can also factor out a 5:
3*9/1 = x
27 = x
The tree is 27 feet tall.
-1
substitute x = -3, so you get 2(-3) + 5 = -`

Answer:
-3/2 and 3/2
Step-by-step explanation:
y=4x^2-9
y=0
4x^2-9=0
4x^2=9
x^2=9/4
x1=-√9/4=-3/2
x2=√9/4=3/2
1500*18%=270
