Let SA =surface area, la=lateral area, b=base, h=height, l=slant height;
b=l
57=3(1/2b²)
57/3*2=b²
b= √38
SA= 1/2 (√38)²+57 cm²= 94 cm²

Step-by-step explanation:
You would subtract 7 from each x value and add 1 to each y value from your original points
Answer:each class would buy 35 rolls.
Step-by-step explanation:
Let x represent the number of rows of either floral sheeting or vinyl glasses that each class would buy.
The freshmen have already spent $307 on their float, plus they need to buy floral sheeting that costs $69 per roll. This means that the total cost of buying x floral sheetings would be
307 + 69x
The sophomores, who have spent $342 so far on theirs, still need to purchase vinyl grass at $68 per roll. This means that the total cost of buying x vinyl grass would be
342 + 68x
Since they are buying the same number of rolls to cover the same area, then
307 + 69x = 342 + 68x
69x - 68x = 342 - 307
x = 35
Answer:
y= -x+4 if x<0
y= x+4 if x≥0
Step-by-step explanation:
When writing a piece-wise function, we simply look at the portion of the graph that covers the given domain and derive an equation.
When looking at the part of the graph when x<0, we can derive the equation:
y= -x+4.
For x-values greater than 0, we can get:
y= x+4.
