Step-by-step explanation:
The parametric equations of the circular cylinder are:
If the orientation of the cylinder is changed to have the height 
along the x-axis, the parametric equations of the cylinder match:
The parametric equations of the circular paraboloid are:
Using the units vectors the parametric equations match:
The parametric equations of the cone are:
Using the units vectors and rotating the base of the cone from 
to 
the parametric equations match:
The equation left is the equation of a plane:
Answer:
The correct answer is - £ 40.5 for 3 large packs.
Step-by-step explanation:
Given:
Large pack = 40 tiles £18
Small pack = 28 tiles £14
Special offer = 25% reduction when you buy 3 or more large packs.
Solution:
Following combinations are possible for tom to get the tiles he needs:
1. 3 large packs
40*3 = 120 tiles with 25% discount
cost = 18*3 - 0.25*18*3 = 40.5
2. 4 small packs
28*4 = 112 tiles
cost = 14*4 = 56
3. 2 large packs and 1 small pack
40*2 + 28 = 108 tiles
cost = 18*2 + 14 = 50
4. 1 large pack and 3 small packs
40 + 28*3 = 124 tiles
cost = 18 + 14*3 = 60
Thus, the correct answer is - 1st case with three large packs.
Answer:
15/8
Step-by-step explanation:
tan 2θ = 2 tan θ / (1 − tan² θ)
tan 2θ = 2 (3/5) / (1 − (3/5)²)
tan 2θ = (6/5) / (1 − 9/25)
tan 2θ = (6/5) / (16/25)
tan 2θ = (6/5) × (25/16)
tan 2θ = 15/8
Answer:
2x(squared)-8x
Step-by-step explanation:
when you distribute the 2x to x you get 2x squared and when 2x is distributed to -4 you get -8x and together you get 2x squared minus 8. :)
