Answer:
The minimum amount of breaking strain the crane can handle is 6350 kg. (Since it is measured to 2 sig. figs, 6349 kg would round down to 6300 kg, hence the min. is 6350 kg.)
The maximum weight of each crate would be 94 kg. (Since it is measured to the nearest 10 kg, 95 kg would round up to 100 kg, hence the max. is 94 kg.)
Therefore, the greatest number of crates that can be safely lifted would be (6350/94) crates which is 67.5 crates, which rounded down is 67 crates.
All numbers are taken as integers in this answer.

Answer:
D. 4X^2+1
Step-by-step explanation:
This is because when you add one after the function it moves it up one unit. When you multiply the first part by four, it causes the function to vertically stretch making it narrower.
<span>C=2πr</span>
where:
<span>C=</span>circumference
<span>r=</span>radius
To find the circumference, substitute your known values into the equation:
<span>C=2πr</span>
<span>C=2π<span>(7)</span></span>
<span>C=14π</span>
<span>C≈43.98 </span>
the circumference is approximately 43.98 cm. Hope I helped!
