The radius r(cm) of a circle is related
to time t(seconds) by the equation
r=0.4t + 1.5.
(a) Calculate the initial value of the
radius.
(b) Find the rate of change of r.

a) 1.5cm

b) dr/dt = 0.4cm/sec

Step-by-step explanation:

r = 0.4t + 1.5

Initial is at t = 0,

r = 1.5 cm

b)

dr/dt = 0.4cm/sec

Slope = change in r/change in t

0.4 is the rate of change in r with respect to time

Alternately,

At t = 0, r = 1.5

At t = 1, r = (0.4)(1) + 1.5 = 1.9

(1.9-1.5)/(1-0) = change in r/change in time

= 0.4 cm/sec

answer

false

explanation

these practices describe the manner the land use outcome is attained. land management methods implemented by corporations are a mandatory because they are a driver for better land use results economically, socially and environmentally. corporations are required to understand the connection between land use , and land management practices to support sustainable land use policies

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
