Well, from triangles we derive trigonometry which can be use to construct bridges, for example, if we want to construct a bridge using some kind of support belief it, it’ll probably be a triangular structure cause it supports more stability
Answer: $2000 + 0.08s ≥ $2500
Step-by-step explanation:
The expression that will be used to calculate the earnings of Liz will be:
= b + (c × s)
Where:
b = base salary = $2,000
c = commission rate = 8% = 8/100 = 0.08
s = the sales that the commission rate will be applied against.
The inequality to find amounts of sales that will meet Liz goal will be:
= b + (c × s)
= $2000 + (0.08 × s) ≥ $2500
= $2000 + 0.08s ≥ $2500
Answer:
(a) 120 square units (underestimate)
(b) 248 square units
Step-by-step explanation:
<u>(a) left sum</u>
See the attachment for a diagram of the areas being summed (in orange). This is the sum of the first 4 table values for f(x), each multiplied by 2 (the width of the rectangle). Quite clearly, the curve is above the rectangle for the entire interval, so the rectangle area underestimates the area under the curve.
left sum = 2(1 + 5 + 17 + 37) = 2(60) = 120 . . . . square units
<u>(b) right sum</u>
The right sum is the sum of the last 4 table values for f(x), each multiplied by 2 (the width of the rectangle). This sum is ...
right sum = 2(5 +17 + 37 +65) = 2(124) = 248 . . . . square units
28 divides by 24 is 1.1666667 which rounds to 1.17 <——answer
