Answer:
Step-by-step explanation:
Given
and
is a vector with 3 times the vector u in opposite direction
option (a) is correct.
Answer:
76 cm
Step-by-step explanation:
P=2L+2w
324=2(86)+2w
324=172+2w
324-172=2w
2w=152
w=152/2
w=76 cm
Answer:
The third choice is the correct one
Explanation:
Square root means that what is under the root has power of 1/2
8 = 4 * 2
Therefore:
√8 = √4 * √2 = 2√2
The given expression:
(8 * x^7 * y*8)^1/2 = (8)^1/2 * (x^7)^1/2 * (y^8)^1/2
= 2√2 * x^7/2 * y^4
= 2√2 * x^3 * y^4 * √x
= 2* x^3 * y^4 √2x
Hope this helps :)
Each cross section has a diameter equal the horizontal distance between the two "halves" of the parabola. We have
y = 4x² ⇒ x = ±√y/2
so the diameter for some given y would be √y/2 - (-√y/2) = √y.
The volume of a cross section with thickness ∆y is then
π/2 (√y/2)² ∆y = π/8 y ∆y
The total volume of the solid would then be
Answer:
1 : 5000
Step-by-step explanation:
Firstly align the unit
Map 5cm represent 250m = 250x100cm = 25000cm
scale = 5 : 25000 = 1 : 5000
