Answer:
Step-by-step explanation:
n²+2 where n is number of small squares forming maximum corner square.
in step 1,n=1
step 2,n=2
step 3,n=3
step 4,n=4
when n=1
number of squares=1²+2=1+2=3
when n=2
total numbers=2^2+2=4+2=6
when n=3
total numbers=3²+2=9+2=11
when n=4
total numbers=4²+2=16+2=18
How many miles did the cars go? You can’t solve the question without that.
Answer:
Step-by-step explanation:
Step-by-step explanation:
By taking ( x = 18°)
<u>L.H.S</u>
cos(3x)=sin(2x)
cos(3x) = cos( 3X18°)= cos (54°)
= cos[ 90° - (2x18°)] ∵[ 90°- (2x18°) = 54°]
= ∴ sin ( 2x18°)
As (x = 18°)
= sin (2x) = R.H.S
Volume of water in the tank:
Differentiate both sides with respect to time <em>t</em> :
<em>V</em> changes at a rate of 2000 cc/min (cubic cm per minute); use this to solve for d<em>h</em>/d<em>t</em> :
(The question asks how the height changes at the exact moment the height is 50 cm, but this info is a red herring because the rate of change is constant.)
