Answer:

Step-by-step explanation:
We need to find the distance between two points i.e. (−5,−1) and (−3,−8).
It can be calculated using distance formula as follows :

We have, x₁ = -5, x₂ = -3, y₁ = -1 and y₂ = -8
Put all the values,

So, the distance between the points is equal to 
Answer:
D. $3.
Step-by-step explanation:
We have been given that a box of 7 items costs $20.79. We are asked to find the cost of each item.
To find the cost of each item, we will divide total cost by total number of items.


Upon rounding our answer to nearest dollar, we will get:

Therefore, the cost of each item will be approximately $3 and option D is the correct choice.
Answer: It is square prism. Even though it is more of a rectangle.
Step-by-step explanation:
The computation shows that the value of the indices will be C. 4.2 × 10^5
<h3>How to calculate the value?</h3>
From the information given, the value will be:
= (7 × 10³) × (5.4 × 10⁴) / (9 × 10)²
It should be noted that in indices when it's multiplication, the powers will be added and subtracted when it's division.
Therefore,
.= (7 × 10³) × (5.4 × 10⁴) / (9 × 10)²
= 4.2 × 10^5
In conclusion, the correct option is C.
