Answer:
The range of the acceptable lengths of the rod is [29.485 30.515]
Step-by-step explanation:
Given,
The ideal length of the metal rod = 30.5 cm,
Also, it can be vary by 0.015 cm,
So, the maximum length that is acceptable = 30.5 + 0.015 = 30.515 cm,
Also, the minimum length that is acceptable = 30.5 - 0.015 = 29.485 cm,
⇒ 29.485 cm ≤ Acceptable length ≤ 30.515 cm
Hence, the range of acceptable lengths would be,
[29.485 30.515]
x < -4.5
<u>Step 1: Solve for x</u>
-10x / -10 > 45 / -10
When dividing or multiplying by a negative, the sign flips.
Answer: x < -4.5

$68-$32=$36
$36/$12= 3
Domain: (-2 , 3]
Range: [-3, 2)
Domain is all the x's on the graph. (If you have an equation, then it's all the numbers that are allowed to be x)
Range is all the y's on the graph (or if you have an equation, all the possible y outcomes)
Open dot endpoint means that point is not included in the set (domain and range are sets of numbers) Closed dot means the point is included.
You didn't get this math question right. But look for all the x's for the domain, and all the y's for the range.
