Answer:

option 4

Step-by-step explanation:

let the side of the square be s , then

length of rectangle = s + 14 and width = s - 4

Since the areas are equal then

s² = (s + 14)(s - 4) ← distribute using FOIL

s² = s² + 10s - 56 ( subtract s² - 56 from both sides )

56 = 10s ( divide both sides by 10 )

5.6 = s

Then

area of square = s² = 5.6² = 31.36 cm²

$\displaystyle\dfrac{1}{\sec x(1-\sin x)}=\dfrac{\cos x}{1-\sin x}\\\\\\\int \dfrac{dx}{\sec x(1-\sin x)}=\int\dfrac{\cos x\, dx}{1-\sin x}\\\\\\u=1-\sin x\\du=-\cos x\, dx\\\\\int \dfrac{\cos x\, dx}{1-\sin x}=\int \dfrac{-du }{u}=-\int \dfrac{du}{u}=-\ln |u|+C=-\ln|1-\sin x|+C$

Answer & Step-by-step explanation:

In the problem, we are given an equation. h(t) = -20 + 11t

In the equation, t represents an unknown value. So, if we are given a number that is in the replacement of t, then we can plug that number in to where t is at.

t = 11

h(11) = -20 + 11(11)

h(11) = -20 + 121

h(11) = 101

So, h(11) is equal to 101
