Where is the picture at? I can't see it. Maybe try uploading.
The correct answer among the given choices is the first one:
“A graph shows Time in hours on the x-axis and Aida’s Distance from Tent
in miles on y-axis. The graph shows three straight lines. The first straight
line joins ordered pairs 0, 0 and 2, 4. The second straight line joins ordered
pairs 2, 4 and 8, 4. The third straight line joins ordered pairs 8, 4 and 9, 0.”
The given ordered pairs is in the format of (t, d) where t is time and
distance is d. Time will always be on the x-axis since it is always an
independent variable.
The first ordered pair should be (2, 4) since it took her 2 hours to
trek to the hilltop. From the given choices, only the 1st and 3rd
choice has this first ordered pairs so we are down to two choices.
Now the second ordered pair should be (8, 4) since she spent 6 hours at
the top but no change in distance. And only the 1st choice has this
value therefore it is the answer.
Answer:
A construction worker may use trigonometry when building the roof of a house. They may have to calculate the right angle that hypotenuse must sit at so water doesn't build up on the roof and cause leaks.
(this may be more of an architect's job, as they are the ones that design the houses)
or
An air traffic controller may use trigonometry to find how long it will take an airplane to land/how far the airplane is from the ground while it is in the sky (hypotenuse), based on its height from the ground (opposite) and the distance away from the runway it is (adjacent). They can also calculate the angle of elevation of the airplane from the tower they work in.
Answer:
4 1/12 is your answer
Find a common denominator, 12. Multiply the many times you did to the denominator to get 12 to the numerator so 3/4 would be 9/12 and 2/3 would be 8/12 so 9/12 - 8/12 is 1/12 and as you know already 10 - 6 = 4 so 4 1/12 would be your answer.
Answer:
12.4967 m
≈ 12.5 m
Step-by-step explanation:
From the solution diagram attached, to find /AB/, we apply sine rule:
AB/Sin 140° =AD/Sin 15°
AB = 10/Sin 15° x Sin 140°
= 24.8372 m
To calculate the height of the pole we will calculate BC first. Using the right angle triangle ∠ABC, we have:
Sin ∅ = BC/AB
Sin 25° = BC/ 24.8372
BC = 24.8372 Sin 25°
= 10.4967 m
The height of the pole = BC + 2.0
= 10.4967 + 2.0
= 12.4967
≈ 12.5 m
