Answer:
3069
Step-by-step explanation:
q=6/3=2
s10=3(2^10-1)÷(2-1)=3×(1024-1)=
3069
because sn=a1(q^n-1)/(q-1)
Answer:
slope = -3
y-intercept = -2
Step-by-step explanation:
y = mx + <em>b</em>
m = slope; <em>b</em> = y-intercept
y= -3x <em>- 2</em>
m = -3 = slope
<em>b = -2 = y-intercept</em>
I pretty sure the answer is 3.2 hours. I'm not completely sure though....
Answer:
At its top floor, the Empire State Building stands <u>1,250 feet (380 meters)</u> tall. Counting the spire and antenna, the building clocks in at a mighty 1,454 feet (443 meters).
Answer:
<em>80.7 ft/sec</em>
Step-by-step explanation:
You need two conversion factors:
1 mile = 5280 ft, so (52780 ft)/(1 mile) = 1
1 hour = 3600 seconds, so (1 hour)/(3600 seconds) = 1
55 mi/hour * (5280 ft)/(1 mile) * (1 hour)/(3600 seconds) = 80.6666... ft/sec
Answer: 80.7 ft/sec
