Answer: {-2, -1, 2}</h3>
The range is the set of all possible y values. So we just list the y coordinates of each point. We only list each unique one ignoring any duplicates.
Step-by-step explanation:
How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!
Answer: The correct answer is: [D]: "8" .
Step-by-step explanation:f y varies inversely with x; then y = k/x ; with "k" being the "constant" in this equation.
You can find the constant by substituting the values given: x = 16, f(x) = y = 2 ;
So, f(x) = y = 2 = k/16 ;
→ 2 = k / 16 ;
Solve for the constant; "k" ;
Multiply EACH SIDE of the equation by "16"
→ 16* (2) = (k / 16) * 16 ;
→ 32 = k ;
↔ k = 32 ;
As such, we can write the equation:
y = k/ x ; as:
→ y = 32/ x ;
Since we are given: "x = 4" ; Plug in that value; and solve for "y" ;
y = 32/4 = 8 .
y = 8 .
y = f(x) ;
So; f(x) = 8 ; which is: Answer choice: [D]: "8" .
So to get to the house it will take 4*1.5 = 6hours
and same for the return if using the same route
The answer is : $36.36
Step-by-step explanation:
The given box is a rectangular box. To find the felt needed to cover the box, we need to find the surface area of the rectangular prism.
Surface area of a rectangular prism = 2(l*w + w*h + h*l), where "l" is the length, "w" is the width and "h" is the height of the rectangular prism.
Given: l = 11 inches; w = 8 inches; and h = 6 inches.
Now plug in these given values in the above formula, we get
Surface area of the rectangular prism = 2 (11* 8 + 8*6 + 6*11)
= 2(88 + 48 + 66)
= 2(202)
= 404
The surface area of the rectangular prism = 404 square inches.
The felt cost 9 cents square inches.
Convert 9 cents to dollar.
9 cents = $0.09
To find the cost of the felt needed to cover prism multiply 404 by 0.09
The total cost = 404*0.09 = $36.36
Hope this helped :)))
