Answer:
B. The graph flips over the x-axis
Step-by-step explanation:
When you plot the coordinate pair (x, y), you plot the point 'y' units above the x-axis. If you change the sign of that (multiply the function by -1), then the point becomes (x, -y), and is plotted 'y' units below the x-axis.
The graph flips over the x-axis.
__
Attached is an example of a function with its original graph (red) and the graph after being multiplied by -1 (blue). The blue graph is a reflection of the red graph across the x-axis.
Use a compass to make a circle around both lasers at the same degree and they should over lap. where they over lap use your straight edge to make a direct line from the point where your at through where they cross. that will be your answer, hope i helped.
<u>To prove the trigonometric equation:</u>
We know that 
, substitute this in place of 1.
Multiply each term of the first term with each term of the 2nd term.
Group like terms together.
= LHS
RHS = LHS
Hence proved.
Answer:
5' 10"
Step-by-step explanation:
We subtract by converting into one measurement. We will choose inches.
8'4"= 96"+4"=100" since 8' has 8(12) inches
2'6"=24+6=30" since 2' has 2(12) inches
Subtract.
100"-30"=70"
We convert back into feet and inches by dividing by 12.
70/12= 5' 10"
Answer:
10 hours
Step-by-step explanation:
speed = distance/time
s = d/t
d = st
d = 75 km/h * 8 h = 600 km
t = d/s
t = 600 km/(60 km/h) = 10 h
Answer: 10 hours
