Answer:
0.15kg
Step-by-step explanation:
Given data
We are told that
0.75 kg of cortos weights 5times the mas of the onion
We want to find the mass of 1 onion
Hence
0.75 kgcortos = 5 onions
x cortos = 1 onions
x= 0.75/5
x= 0.15kg
Hence 1 onion will weigh 0.15kg
Answer:
Area of rectangle,
.
Step-by-step explanation:
We are given with side lengths of a rectangle are (2x-4) units and (x+1) units. It is required to find the area of rectangle.
The area of a rectangle is equal to the product of its length and breadth. It is given by :

Let us consider, L = (2x-4) units and B = (x+1) units
Plugging the side lengths in above formula:


So, the function that models the area of a rectangle is
.
Answer:
The complex number
has Cartesian form
.
Step-by-step explanation:
First, we need to recall the definition of
when
is a complex number:
.
Then,
. (I)
Now, recall the definition of the complex exponential:
.
So,

(we use that
.
Thus,

Now we group conveniently in the above expression:
.
Now, substituting this equality in (I) we get
.
Thus,

.
