Answer:
Step-by-step explanation:
To find the distance between (8, -3, 4) and (6, -4, 1), use the distance formula for (x,y,z) points. It is very similar to (x,y) points.
A home cleaning service takes more time to clean larger spaces. The table shows the number of minutes it takes for the service t
1 answer:
The time required to clean 200 square feet will be 80 minutes. Option B is correct.
<h3>What is the surface area?</h3>The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.
Let x be the cleaning time for the 200 square feet area;
From the table, it is observed that for a 1 sq. foot area the time needed to clean will be 0.4 minutes.
1 square feet = 0.4 minute
200 square feet = 200 × 0.4
200 square feet = 80 minute
The time required to clean 200 square feet will be 80 minutes.
Hence, option B is correct.
The table is attached in the attachment.

The square of a prime number is not prime.
a) let x ∈ R, If x ∈ {prime numbers}, then ∉{prime numbers}
there says that if x is a real and x is in the set of the prime numbers, then the square of x isn't in the set of prime numbers.
b) Prove or disprove the statement.
ok, if x is a prime number, then x only can be divided by himself. Now is easy to see that = x*x can be divided by himself and x, then x*x is not a prime number, because can be divided by another number different than himself
