Answer:
l = gt²/(2π)²
Step-by-step explanation:
if T = 2π√l/g
squaring both sides
(T)² = (2π)² × (√l/g)²
T² =4π² × l/g
T² = 4π²l/g
using cross multiplication techniqes
gT² = 4π²l
divede both sides by " 4π²"
gT²/4π² =4π²l/4π²
gT²/4π² =l
l = gT²/(2π)²
that is the final answer.
Answer:
b=320; slope=-30
Step-by-step explanation:
if you look along the y-axis find the spot that the line intercepts and then that's b
now for the slope
find two points on the line, i chose(8 , 120) and (4 , 240)
use the slope formula: y2-y1 over x2-x1
240-120=120 and 4-8= -4
so the slope is 120/-4 and that can be simplified to 30/-1 or -30

Answer:
Step-by-step explanation:
g(-2)=2(-2)^3+3(-2)^2-3(-2)+4=-16+12+6+4=6
g(-1)=2(-1)^3+3(-1)^2-3(-1)+4=-2+3+3+4=8
it does not change sign ,so there is no real zero between -2 and -1.
