Answer:
2√2.
Step-by-step explanation:
We use the Pythagoras Theorem:
x^2 = 2^2 + 2^2
x^2 = 8
x = √8
= 2√2.
Answer:
B
I
Step-by-step explanation:
A triangle's angles must add up to 180
68+90+x=180
158+x=180
22=x
3 and 2 must add up to 180
70+x=180
angle 2= 110
angle 2 and angle 1 have to add up to 180 as well
110+x=180
andgle 1= 70
Answer: 0.00133m/s
Step-by-step explanation:
Given
distance crawled by the snail = 6cm = 0.06m
Time taken = 0.75minutes = 0.75*60
Time taken = 45secs
Required
constant rate of change of the snail's crawl (speed)
Speed of the snail = distance/time;
Speed of the snail = 0.06/45
Speed of the snail = 0.00133m/s
Hence the constant rate of change of the snail's crawl in m/s is 0.00133m/s
