Answer:
time = 2.48 seconds
Step-by-step explanation:
Given data:
distance = 100 foot
Initial velocity = 0 <em>because it was held and being released.</em>
acceleration is gravitational force
<em>gravitational force in feet per second = 32.2 ft/s²</em>
<em>formula for distance is s = ut +(1/2)at² where s = distance , u = intial velocity , a = acceleration and t = time</em>
s = ut +(1/2)at²
100 = 0(t) + (1/2)(32.2)t²
100 = 16.2t²
100/16.2 = t²
therefore t = 2.484
t = 2.48 seconds (to 2 decimal places)
Answer: 2^5
Step-by-step explanation:
2^2 * 2^3 you add the exponents
Answer:
Step-by-step explanation:
f(x) = (x + 5)(x - 1)
using the ' factor theorem '
given x = a is the root of a polynomial then (x - a ) is a factor
here roots are x = - 5 and x = 1 hence factors are (x + 5) and (x - 1)
the polynomial is the product of the factors
f(x) = (x + 5)(x - 1)
