Step-by-step explanation:
- 35/10(2-15n/10) 145n/10 - 7 - 6n
-70/10 +35*15n/100.145n/10 -7-6n
-7 + 525n/100.145n/10 -7- 6n
-14 +5.25n .14.5n -6n
-14 +76.125n^2 -6n is final answer
Answer:
15 inches
Step-by-step explanation:
The longest side of the right triangular window frame is 39 inches
The height is 36 inches
Let the base of the window frame be x inches
So according to Pythagoras theorem,
x² + 36² = 39²
x² = 39² - 36² = 225
x = 
= 15 inches
The third side of the window frame is therefore equal to 15 inches.
Answer:
dI/dt= -0,000127 A/s
Step-by-step explanation:
From Ohm's Law we have V = IR . deriving on both sides of equality
dV/dt = dI/dt R + I dR/dt . clearing, dI/dt = 1/R (dV/dt - I dR/dt)
replacing by the values of the statement
dI/dt = 1/400Ω (-0,05 V/s - 0,02 A 0,04Ω/s) . making calculations
dI/dt = -0,0508V/s / 400Ω = -0,000127 V/sΩ. simplifying the units
dI/dt = -0,000127 A/s
Using I=PRT/100
replacing the given information;
(p+prt)=P×r×t
⇒p+prt=P×rt
P=(p+prt)/(rt)
Principal(P)= (p/rt)+p
=p((1/rt)+1)
