Because the two vertices have the same x-coordinate, the side is a vertical line. It starts vertically from -18 to 18
the length = 18 - (-18)
the length = 18 + 18
the length = 36
The length of the side is 36 unit
Answer:
158.13 ft²
Step-by-step explanation:
→ Calculate area of square
8 × 18 = 144
→ Find radius of circle
18 - ( 6 × 2 ) = 6 ÷ 2 = 3
→ Find area of circle
(3.14 × 3²) ÷ 2 = 14.13
→ Add on the area of the rectangle
14.13 + 144 = 158.13
Answer:
The range is [-11, ∞).
Step-by-step explanation:
f(x)=3x^2+6x-8
This is a parabola which opens upwards.
Convert to vertex form:
= 3(x^2 + 2x) - 8
= 3 [ (x + 1)^2 - 1] - 8
= 3(x + 1)^2 - 3 - 8
= 3(x + 1)^2 - 11.
The minimum value is -11 so the range is [-11, ∞).
Step-by-step explanation:
Answer: The system will succeed when the first alarm rings or when the first one fails, but the second one rings. The probability of this is 0.98
The probability of system failure is 1-(probability of success)= 1-0.98= 0.02
Step-by-step explanation:
<span>y − 3(x − 1) = 0.
y - 3x + 3 = 0
y = 3x - 3
slope m = 3
y-intercept (0, -3)</span>
