Sina - (cosa)(tanb)/cosa + (sina)(tanb)
sina ≡ (tana)(cosa)
(tana)(cosa) - (cosa)(tanb)/cosa + (tana)(cosa)(tanb)
= cosa(tana - tanb)/cosa(1 + tanatanb)
(cosas cancel out)
= (tana - tanb)/(1 + tanatanb) ≡ tan(a-b)
Answer:
0.00324 or in scientific notation 3.24×10^-3
Step-by-step explanation:
MASS OF SINGLE ELECTRON = 5.4×10^-4
MASS OF 6 ELECTRONS = 6× 5.4×10^-4
=32.4×10^-4
= 3.24×10×10^-4
= 3.24×10^-3
The change in grandpa Ernie's height each year is equal to 0.6cm.
As given in the question,
Number of years for which grandpa's height is shrinking = 4 years
The total decrease in height after four years is equal to 2.4cm.
Let x represents the decrease in height each year
The required equation to calculate decrease in height each year is given by:
4x = 2.4
⇒ x= 2.4 /4
⇒x = 0.6cm
Therefore, the change in grandpa Ernie's height each year is equal to 0.6cm.
The complete question is :
Grandpa Ernie is shrinking over the past four years his height decreased by a total of 2.4 cm it decrease by the same amount each year what was the change in grandpa Ernie’s height each year.
