“RMS” is an abbreviation for Root Mean Square.For Alternating Current (AC) in North America, the common rating for residential receptacles is nominally 120 Volts RMS.

This phenomenon is called 'Bio- magnification'

Volume = pi*r*r*h=> h = 27720/[21*21*(22/7)]=> h = 20 cm.

Curved Surface Area = 2*r*pi*h= 2*21*(22/7)*20= 2640 sq cm

volume of plank=lbh=30*15*5=2250cu cmfor number of planks=33750/2250=15 planks

the volume of a wooden planks is 33,750cu.cm.if cuboidal pieces measuring 30cm in length, 15cm in width and 5cm in height have to be cut from the wooden plank ,how many pieces of cuboids can be cut from the planks?

Given :H = 5 cmW = 5 cmL = ?Volume = 300 cm³

So, Volume of cubiod = L×W×H300 = L × 5 × 5L = 300/25 = 12 cm

So, surface area of cubiod= 2 × ( LW + LH + WH)= 2 × ( 60 + 60 + 25)= 2 × ( 120 + 25)= 2 × ( 145)= 290 cm

please solve equations also and the height is 21cm

x 10 answer bro it is right

जब किसी प्रतिनिधित्व निर्वाचन क्षेत्र में एक सीट खाली हो जाती है, तो परिणाम अलग-अलग होते हैं। उदाहरण के लिए, केवल उप-चुनाव भरने के लिए उप-चुनाव आयोजित किया जा सकता है या निर्वाचन क्षेत्र की सभी सीटों को उप-चुनाव में लड़या जा सकता है।

सरकार के भंग होने पर या मिटने की स्थिति में यह उपचुनाव होते हैं।

please like the solution 👍 ✔️

Length of roller = 1m = 100cm

Circumference of roller = π x D = 22/7 X 84 = 264 cm

Length of road = 264 x 750 = 198000 cm

Width of road = length of roller = 100 cm

Area of road = 198000 x 100 = 19,800,000 cm² or 1980 m²

External diameter of the iron pipe=25 cm

=>external radius=rₑ=25/2 cmThickness=t=1 cm=>Internal radius=rᵢ=25/2-1=23/2 cm.Length of the iron pipe=h=20 cm

∴Total surface area=2πrₑh+2πrᵢh+2{π(rₑ²-rᵢ²)}=2×3.14×25/2 ×20 + 2×3.14×23/2×20+ 2{π((25/2)²-(23/2)²)} =3165.12 cm²

thnx

ok

Let the incomes of A, B and C be 2x, 3x and 5x.

With the increments which A, B and C receives their salaries will be 2.3x, 3.3x and 6x. The ratio of the new incomes (post increments) of A, B and C will be

2.3 : 3.3 : 6.=23 : 33 : 60

first one is in second quadrent and second one is in 4 rd quadrent

2/√x+3/√y= 24/√x- 9/√y= -1Let 1/√x=pand 1/√y=q, then the equations changes as below:2p+ 3q = 2 ...(i)4p - 9q = -1 ...(ii)Multiplying equation(i)by 3, we get6p + 9q = 6 ...(iii)Adding equation(ii)and(iii), we get

10p = 5

p = 1/2 ...(iv)

Putting in equation(i), we get

2 × 1/2+ 3q = 23q = 1q = 1/3

p= 1/√x= 1/2√x= 2x= 4andq= 1/√y= 1/3√y= 3y= 9Hence,x= 4,y= 9

HI

The given information is absurd as line x = -4 and x - axis are not parallel they intersect each other.

But how do I draw it In the graph form?

Thanks!!!

x=2 is perpendicular to the x-axis. Thus, it makes an angle of 90 degrees with the x-axis.

x=2 is parallel to the y-axis. Thus, it makes an angle of 0 degrees with the x-axis.

Analogous organs are the opposite of homologous organs, which have similar functions but different origins. An example of an analogous trait would be the wings of insects, bats and birds that evolved independently in each lineage separately after diverging from an ancestor without wings.

Reverse or opposite

Dividing the given equation by cos^4 theta we get,

tan^4 theta + (tan^2 theta) x (sec^2 theta) = sec^4 theta

changing sec into tan by formula

sec^2 theta = 1+ tan^2 theta

we get the answer 1

Please post complete and clear image of the question

if f(x+a)=f(x), then a is the period of the function f(x).

Here,

f(x)=|sin x|+|cos x|

Here the range of |sin x| is [0,1].

Similarly, range of |cos x| is also [0,1]

So, when we consider a=π/2.

f(a+x)=|sin(x+π/2)|+|cos(x+π/2)|.

sin(x+π/2) is equal to cosx.

cos(x+π/2) is equal to -sinx.

However, we have the modulus function to convert the -sinx to sinx.

While, cosx will remain the same.

Here, the range of both functions will be the same as it was, for f(x).

So, f(x)=f(x+{π/2}).

So, it also applies for integral multiples of π/2.

So, period of the function is π/2.

If x = –π we know sin –π = 0 but cos –π = – 1 so y = 0 + 1 = 1
