Answer:

(2/3)(e^t +1)^(3/2)

Step-by-step explanation:

Use the substitution ...

u = e^t +1

Then du = e^t and you are finding the integral of ...

∫u^(1/2)·du

which you know by the power rule is ...

(2/3)u^(3/2) = (2/3)(e^t +1)^(3/2)

Find the inequality for this graph

Arada [10]

ANSWER

$y \geqslant - 2x - 5$

EXPLANATION

First we need to find the equation of the boundary line which passes through (-1,-3) with a y-intercept of -5.

The slope of this line is

$m = \frac{ -5 - - 3}{0 - - 1} = - 2$

The equation of this line is

$y = - 2x - 5$

Since the boundary line is solid and the upper half plane is shaded the required inequality is

$y \geqslant - 2x - 5$
