Find the interval on which the curve of y equals the integral from 0 to x of 2 divided by the quantity 1 plus 3 times t plus t s

elena-14-01-66 [18.8K]

$y=\displaystyle\int_0^x\frac2{1+3t+t^2}\,\mathrm dt$

By the fundamental theorem of calculus,

$\dfrac{\mathrm dy}{\mathrm dt}=\dfrac2{1+3x+x^2}$

then by standard differentiation,

$\dfrac{\mathrm d^2y}{\mathrm dt^2}=-\dfrac{6+4x}{(1+3x+x^2)^2}$

$y$ is concave upward whenever $\dfrac{\mathrm d^2y}{\mathrm dt^2}>0$ . The denominator is always positive, so the sign is determined by the numerator alone:

$6+4x>0\implies x>-\dfrac32$

HELP FAST I’LL MARK YOU BRAINLIEST What is the slope of a line perpendicular to the line whose equation is 6x+4y=72. Fully reduc

denis23 [38]

Answer:

2/3

Step-by-step explanation:

6x + 4y = 72

-6x -6x

4y = 72 - 6x

/4 /4

y = 18 - 6/4x

y = -6/4x + 18

perpidicular slope is the opposite reciprical of the original line:

-6/4 is the slope of the line above.

4/6 or 2/3 would be the desired slope

check:

the two slopes mutplied would equal -1

-6/4 x 2/3 = -12/12 = -1
