Answer:

First is $x^{2} +4xy+4y^{2}$

Second is $y^{2} +4xy+4x^{2}$

Step-by-step explanation:

Open up equations and do FOIL method.

First equation:

(x + 2y)(x + 2y)

x^2 + 2xy + 2xy + 4y^2

$x^{2} +4xy+4y^{2}$

Second equation:

(y + 2x)(y + 2x)

y^2 +2xy + 2xy + 4x^2

$y^{2} +4xy+4x^{2}$

John is looking up at the top of the Empire State Building from 1 mi. away and measures the angle of elevation to be 11 degrees.

torisob [31]

Refer to the attached image.

Let the height of the Empire State Building = BC = 'x'

John is standing at distance from Empire State Building = AB = 1 mile

The angle of elevation = 11°

In triangle ABC,

Consider $\tan 11^{\circ}= \frac{Perpendicular}{Base}$

$\tan 11^{\circ}= \frac{BC}{AB}$

$\tan 11^{\circ}= \frac{x}{1}$

$0.194= \frac{x}{1}$

x = 0.194 mile

Since 1 mile =5280 feet

So, x = $0.194 \times 5280$

= 1024.32 feet.

So, the height of the Empire State Building is 1024.32 feet.

Answer: 0.9844

Step-by-step explanation:

given data:

sample size n = 6

It’s assumed that half the population are male and the remaining half are females

F = 1/2

M = 1/2

the probability that the investigator would draw altleats one male

P ( x ≥ 1 ) =

= 1 - ( 0.5 ) ^ 6

= ( 0.5 )^6

= 0.9844

Find the height of a cone with volume 4034.66 cm^3 and radius 13 cm.

pav-90 [236]

Volume of cone=4034.66cm^3
Pi×r^2×h/3=4034.66
Pi×13×13×h=4034.66×3
22×13×13×h/7=4034.66×3
h=4034.66×3×7/13×13×22
h=45.57
So h=45.6cm
