Deepika on her way to home saw some homeless person sleeping in the park in a winter night. she gave them her canvas area of 551

Romashka [77]

Total area of canvas used in the cunstruction of the tent = 551 - 1 = 550 meters square.
Area of a cone = πr(r + sqrt(h^2 + r^2))
22/7 * 7(7 + sqrt(h^2 + 7^2)) = 550
7 + sqrt(h^2 + 49) = 550/22 = 25
sqrt(h^2 + 49) = 25 - 7 = 18
h^2 + 49 = 18^2 = 324
h^2 = 324 - 49 = 275
h = sqrt(275) = 16.58

The volume of the tent is the volume of a cone with base radius of 7 meter and height of 16.58 meter.
Volume of a cone = 1/3 πr^2h
= 1/3 * 22/7 * 7^2 * 16.58 = 851.3 m^3

Use the squared identities to simplify 2sin^2 x cos^2 x

guapka [62]

The given question is

$2sin^2 x cos^2 x$

Multiplying and divide by 2

$\frac{4sin^2 x cos^2 x}{2} =\frac{(2 sinx cos x})^2{2}=\frac{sin^2(2x)}{2}$

Again multiplying and dividing by 2

$\frac{2sin^2(2x)}{4}$

And

$2 sin^2(2x)=1-cos(4x)$

So we will get

$\frac{1-cos(4x)}{4}$

Correct option is D

The graph of the parent function p(x)=x^2 passes through the point E (21,184). The graph p is transformed such that the new grap

NemiM [27]

The new coordinates of E are (13 , 179)

Step-by-step explanation:

Let us revise some transformation

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k

∵ p(x) = x²

∵ The graph p is transformed such that the new graph represents

the function f(x)

∵ f(x) = (x + 8)² - 5

∴ x of p(x) is add by 8 and p(x) subtracted by 5

- By using the 2nd and 4th rule above

∴ The graph of p(x) is translated 8 units left and 5 units down

∵ Point E (21 , 184) lies on the graph of the parent function p(x)

∴ Point p translated 8 units to the left and 5 units down

- That means subtract 8 from its x-coordinate and 5 from its

y-coordinate

∴ The new coordinates of E = (21 - 8 , 184 - 5)

∴ The new coordinates of E = (13 , 179)

The new coordinates of E are (13 , 179)
