Answer:
Height will have changed by -2/5
Step-by-step explanation:
change in height = (change in height/hour) × hours
= (-2/25) × 5 = -2/5
Hey!
Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get

on its own.
<em>Original Equation : </em>

<
<em>New Equation {Changed by Multiplying 2 on Both Sides} :</em>

<

(

)
And we simplify the equation to get our answer.
<em>Old Equation :</em>

<

(

)
<em>New Equation {Changed by Simplification} :</em>
y < -6
<em>So, the equation

< -3 simplified is</em>
y < -6.
Hope this helps!

Answer:
log(32/125)
=log32 - log125 [log(x/y)=log(x) - log(y)]
=log(2)^2 - log(5)^3
=2log2-3log5 [log(x)^p=p log x]
=2a-3b
Answer:
- resistance: (2r +5)
- current: (3i +4)
Step-by-step explanation:
The factors of the given expression are ...
6ir +15i +8r +20 = (3i +4)(2r +5)
Which factor is current and which is resistance is not clear. Usually, resistance is referred to using the variable r, so we suppose the expressions are supposed to be ...
resistance: (2r +5)
current: (3i +4)
15x²+16x+4 =0 (ax² +bx +c=0)
Δ = b²-4ac =256 - 4×15×4 =16
x1 = (-b+√Δ) / 2a = (-16+√16) / 30 =( -16+4) / 30 = -12/30 = - 2/5
x2 = (-b -√Δ) / 2a = (-16 -√16) / 30 = (-16 -4) /30 = -20/30 = -2/3
