![\frac{WR}{v^2} =t](https://tex.z-dn.net/?f=%5Cfrac%7BWR%7D%7Bv%5E2%7D%20%3Dt)
Step-by-step explanation:
![W = \frac{v^2t}{R}\\\\W\cdot R = v^2t\\\\\frac{WR}{v^2} =t](https://tex.z-dn.net/?f=W%20%3D%20%5Cfrac%7Bv%5E2t%7D%7BR%7D%5C%5C%5C%5CW%5Ccdot%20R%20%3D%20v%5E2t%5C%5C%5C%5C%5Cfrac%7BWR%7D%7Bv%5E2%7D%20%3Dt)
Total mass of the filled aquarium = 3*3 * 62 = 1674 pounds
As the table can only support 200 lbs the aquarium should not be put on the table.
(b) No the deisity of the water is a constant
About 172 centimeters tall.
Since he is about 3/4 his average adult height, you simply divide his current height by .75
129/.75 = 172
Answer:
A
Step-by-step explanation:
For point-slope form, you need a point and the slope.
y - y₁ = m(x - x₁)
Looking at the graph, the points you have are (4, 0) and (-4, -4). You can use these points to find the slope. Divide the difference of the y's by the difference of the x's/
-4 - 0 = -4
-4 - 4 = -8
-4/-8 = 1/2
The slope is 1/2. This cancels out choices C and D.
With the point (-4, -4), A is the answer.
