Answer:
Step-by-step explanation:
40.2=3(x+2)
134=10x+20
134-20=10x+20-20
114=10x
11.4=x
The triangles are similar by the SSS (side-side-side) similarity theorem because the sides of the two triangles are in proportion (5/15 = 3/9 = 4/12)
Hope this helps =)
20mn - 30m
As you can see, both numbers are divisible by 10m. So if you were to divide them both, you would be left with, 10m (2n - 3), which would be the correct answer.
Answer:
1.083
Step-by-step explanation:
2.75-(9+6)/9
Answer:
1) gradient of f = (1/y)i+(-x/y^2)j
2) rate of change of f at P in direction of v = i - 1/16 j
3) maximum rate of change at P= (√17)/16
4) unit vector of maximum rate of change = 4/√17 i + 1/√17 j
Step-by-step explanation:
The explanation can be found in the attached picture
Note:
Since the gradient vector represents the direction of maximum change:
3) The maximum rate of change is the modulus of the gradient vector
4) The unit direction vector of maximum rate of change is the unit gradient vector.
