On one afternoon in a shoe warehouse, three large shipments of shoes arrived. The weights of the shipments were 1 ton 115 pounds
1 answer:
Alright, lets get started.
The weight of first shipment = 1 ton 115 pounds
As we know, 1 ton = 2000 pounds, so
So, the weight of first shipment = pounds
The weight of second shipment = 1723 pounds 7 ounces
The weight of third shipment = 957 pounds 11 ounces
So, adding all three weights =
So, all three weights = 4795 pounds 18 ounces
As we know, 16 ounces = 1 pound, so
all three weights = 4795 pound 1 pound 2 ounces
All three weights = 4796 pounds 2 ounces
4796 could be wriiten as 4000 + 796
As we know, 2000 pound = 1 ton so
All three weight = 2 tons 796 pounds 2 ounces
So, the total weight of three shipments = 2 tons 796 pounds 2 ounces : Answer

The true statement is:
"The range of the function is all real numbers less than or equal to 9."
<h3>Which statements are true?</h3>
Here we have the quadratic function:
And we want to see which of the given statements are true.
The first one is:
"The domain is al real numbers less than or equal to -2"
This is false, for all quadratic functions the domain is the set of all real numbers (unless the domain is defined).
The second statement is:
" The domain of the function is all real numbers less than or equal to 9."
Also false
Third one:
" The range of the function is all real numbers less than or equal to −2"
The range of a quadratic function with a negative leading coefficient will be the set of all the values smaller than the y-value of the vertex.
In this case, the quadratic function is:
So the vertex is at:
Then the y-value of the vertex is:
So the range is the set of all real numbers less than or equal to 9.
So the above statement is false, and the final one:
"The range of the function is all real numbers less than or equal to 9."
Is the true statement.
