Answer:

The answer is 20

Step-by-step explanation:

Given that f(2)=1/5

And f(n+1)=f(n)*10

Let's start from n=2

f(2+1)=f(2)*10

f(3)=(1/5)*10

f(3)=2

Now let's take n=3

f(3+1)=f(3)*10

f(4)=2*10

f(4)=20

What is the slope of a line that is parallel to the line y = 3/4 + 2?

Elodia [21]

3/4 because it’s parallel so it has the same slope. It just doesn’t pass through the same line.

Which of these is a unit of density?

Naddika [18.5K]

<h3><u>Answer:- </u></h3>

$\longrightarrow \textsf{The unit of density is\;}$ $\sf kg/m^3$

<h3><u>Solution</u> :-</h3>

$\green{ \underline { \boxed{ \sf{Density = \frac{Mass}{Volume}}}}}$

$\longrightarrow$ The unit of mass is kg and unit of Volume is m³ . Since density is division of mass by volume , the corresponding units will also get divided and unit of density would come out to be kg/m³

<u>Some basic </u><u>derived </u><u>Units :- </u>

area => m²
volume cubic meter => m3
speed meter per second => m/s
acceleration => m/s²
mass density meter => kg/m3
specific volume cubic meter per kilogram m³/kg

Solve sin^2x+cos2x-1/4=0

sweet-ann [11.9K]

$sin^{2}x + cos2x - \frac{1}{4} = 0$
$sin^{2}x + cos^{2}x - sin^{2}x = \frac{1}{4}$
$cos^{2}x = \frac{1}{4}$
$cos(x) = \pm \frac{1}{2}$

$x = \pm \frac{\pi}{3}$
General solutions: $x = \pi(n - \frac{1}{3})$ and $x = \pi(n + \frac{1}{3})$
