Answer:

b^2-16 , 16a^2-4

Step-by-step explanation:

m^2+36 is not a difference its a sum so that is automatically ruled out

3x^2-4, 3 isn't a squared number so it can not be used

b^2-16 , is a difference of squares - (b-4)(b+4)

16a^2-4, is also a difference of squares - (4a-2)(4a+2)

Evaluate the double integral. . ∫∫ y sqrt(x^2-y^2) dA, R={(x,y)|0≤y≤x, 0≤x≤1}. R. . Please explain

polet [3.4K]

First we will evaluate: ( substitution: u = x² - y², du = - 2 y dy )
$\int\limits^x_0 {y \sqrt{ x^{2} - y^{2} } } \, dy= \\ \frac{-1}{2} \int\limits^x_0 { u^{1/2} } \, du =$
= $\frac{-1}{3} \sqrt{ (x^{2} - y^{2} ) ^{3} }$ ( than plug in x and 0 )
= $- \frac{1}{3} ( \sqrt{( x^{2} - x^{2}) ^{3} } - \sqrt{ (x^{2} -0 ^{2} ) ^{3} }$ =
= 1/3 x³ ( then another integration )
$1/3\int\limits^1_0 { x^{3} } \, dx = 1/3 ( x^{4}/4)}= 1/3 ( 1 ^{4}/4 - 0^{4} /4 )$
= 1/3 * 1/4 = 1/12

When a fair coin is flipped, the probability of its landing heads (H) is 0.500.50 and the probability of its landing tails (T

DedPeter [7]

Answer:

probability (HH) = 1/4 = 0.25

probability (HT) = 1/4 = 0.25

probability (TH) = 1/4 = 0.25

probability (TT) = 1/4 = 0.25

Step-by-step explanation:

given data

probability heads (H) is 0.50

probability heads (T) is 0.50

to find out

the probabilities of each arrangement

solution

when coin toss there are two outcome that is head or tail

and then flip 2 time

possibility are HH HT TH TT

probability (HH) = 1/4 = 0.25

probability (HT) = 1/4 = 0.25

probability (TH) = 1/4 = 0.25

probability (TT) = 1/4 = 0.25
