Acceleration due to gravity is 32.2 ft/s^2
68=32.2t
t=2.11 seconds
h=68t-32.2/2*t^2
h(2.11)=68*2.11-32.2/2*2.11^2
h=71.8 feet

Answer:
Distance=3.1 miles
Step-by-step explanation:
Step 1: Determine how many meters make a mile
The conversion rate expression is;
1 mile=1.60934 kilometers
Step 2: Convert 5 km to miles
Using the expression below;
Distance in miles=distance in kilometers/1.60934
where;
distance in kilometers=5 km
replacing;
Distance in miles=5/1.60934
Distance in miles=3.10686 miles
Step 3: Round off to nearest tenth of a mile
Nearest tenth of a mile=1/10=0.1 , the same as rounding of to the nearest 1 decimal place
Distance 3.10686 miles rounded off to 1 decimal place=3.1 miles
Distance=3.1 miles
Find two numbers that add to -4 and that multiply to -21.
After playing around with some numbers, I got -7 and 3.
So, the factored form is (x - 7)(x + 3).
Answer:
110beats/minutes
Step-by-step explanation:
we know we have 11 beats every 6 seconds,
that implies that there are 110 beats every 60seconds
and 60secs is a minute
that means 110beats/mins
