Answer:
The least amount spent is £12.92
Step-by-step explanation:
Given
Number of Carton = 38
A carton = 45 pence
4 carton = £1.56
To spend the least amount of money, be needs to go for the least expensive option.
There are 100 pence in £1
So, there are x pence in £1.36
x * 1 =1.36 * 100
x = 136 pence for 4 carton.
To get the price of 1 carton, divide x by 4
x/4 = 136p/4
x/4 = 34 pence.
This means that he can get a carton of juice at the rate of 34p and at the rate of 45p.
The smallest of this is 34p.
Hence total amount spent =
34 * 38
amount = 1292p --- convert to £
Amount = 1292/100
Amount = £12.92
Hence, the least amount spent is £12.92
Answer with explanation:
It is given that , ride at an amusement park moves the riders in a circle at a rate of 6.0 m/s.

Radius of Circle = 9.0 meters
Acceleration is rate of change of velocity,which will be perpendicular to radius vector.
Also, in terms of mathematics, line from center that is radius , to point of contact that is tangent line ,which is on the circle are perpendicular to each another.
→r(radius vector) ⊥ a(Acceleration vector).
So, In option A, Radius vector is Perpendicular to acceleration of riders.
Answer: 
Step-by-step explanation:
Since you did not indicate what you need to do, I assume that you have to write an expression using the sentence given in the problem.
In order to solve this exercise, it is importat to remember the following information:
1. The quotient is the result of a division.
2. The sum is the result of an addition.
3. The word "twice" indicates a multiplicatio by 2.
4. The word "cube" indicates an exponent 3.
Then, keeping on mind the explained above and the data given in the exercise, you know that:
-The sum of
and
can be expressed as:

- Twice the cube of
can be expressed in the following form:

Therefore, you can dermine that "the quotient of the sum of
and
and twice the cube of
" is represented with the following expression:

O

So, we have 3 square roots.
The number under a square root sign must be
Non negative.
Beside that the denominator must be not equal zero.
For the term ⇒⇒⇒
∴ x > 0 ⇒⇒⇒ x ∈ (0,∞)
For the term ⇒⇒⇒
∴x+1 ≥ 0 ⇒⇒⇒ x ≥ -1 ⇒⇒⇒ ∴ x ∈ [-1,∞)
For the term ⇒⇒⇒
∴ 1-x ≥ 0 ⇒⇒⇒ x ≤ 1 ⇒⇒⇒ x ∈ (-∞,1]
So, The values of x which make the <span>
expression well defined</span>
<span>
∴ x ∈ { </span><span>
(0,∞) ∪ </span><span>
[-1,∞) ∪ </span><span>
(-∞,1] }</span><span>
</span><span>
∴ x ∈ [-1,0) ∪ (0,1]</span><span>
</span><span>
OR can be written as ⇒⇒ x ∈ [-1,1] - {0}</span>
