Answer:

6

Step-by-step explanation:

The value of the square length of the hypotenuse is equal to sum of the square length of the two legs: let x represent the missing side

\sqrt{} 85^{2} = 7^2 + x^2 calculate the powers

85 = 49 + x^2 subtract 49 from both sides

36 = x^2 find the root of the both sides

6 = x

borishaifa [10]

Step-by-step explanation:

x approches negative infinity

so : |x|= -x

replace it in the expression

\frac{-x}{x+1}

so :

\lim_{x \to \-infty} \frac{-x}{x+1}= limx⇒-∞( -x/x)   you take the terms with the highest degree

so limx⇒-∞ (-x/x)  = -1

Find the value of y.<br><br> 5<br> 8<br> 4<br> 2<br><br> 50 Pts!
Vinvika [58]

Answer and Explanation:

Since this is a 30-60-90 triangle, you can use the ratio of side lengths specific to this type of triangle:

x = 4√(2)

y = 2(4) = 8

because where 4 = T,

x = T√2    and     y = 2T

so again:

x = 4\sqrt{2}\\y = 8

polet [3.4K]

Answer:

12.566

Step-by-step explanation:

A = ∫1/2(r)^2dtheta from a - b = 0 to 2π

∫1/2(sin^2theta-4sintheta+4)dtheta

[9/4theta+2costheta-1/8sin2theta] from 0 to 2π…

when you solve this you get 14.137 without taking out the cos(2theta+3)
