Answer:
Step-by-step explanation:
Given that the amount of chlorophyll in a leaf changes based on outside temperature. Here there are two variables.
i) Amount of chlorophyll in a leaf
ii) outside temperature
Here outside temperature is an independent variable as amount of chlorophyll in a leaf cannot control it.
But on the other hand, Amount of chlorophyll in a leaf depends on the outside temperature and hence cannot be independent but dependent variable
Recall the definition of dependent and independent variable
An independent variable is the variable that is controlled in a scientific experiment to test the effects on the dependent variable.
A dependent variable is the variable being tested and measured in a scientific experiment.
Answer: 48
Step-by-step explanation:
To get the answer divide 98 by 2
Answer:
∠JKM = 42°
Step-by-step explanation:
Since M is in the interior of ∠JKL, then
∠JKM + ∠MKL = ∠JKL ← substitute values
∠JKM + 42 = 84 ( subtract 42 from both sides )
∠JKM = 42°
The telescope the cliff and the eagle will from a right tingle as you can see in the picture. The distance between the base of the cliff an the telescope will be the adjacent side of the elevation angle.
The opposite side of the elevation angle will be the height of the cliff 1.3 meters above the ground.
Now, to find the opposite side,
, of our elevation angle, we are going to use the trig function tangent:
Finally, we are going to add the height of the telescope and the height of the cliff above the ground:
We can conclude that the eagle is 91.9 meters above the ground; therefore, the correct answer is <span>
B 91.9 m</span>
