Find all the values of k so that the given points are 29 square units apart. (-5, 5) and (k,0).

Varvara68 [4.7K]

Distance formula between 2 points (x1,y1) and (x2,y2)

D= $\sqrt{(x1-x2)^{2}+(y1-y2)^{2}}$

D=29 and one point is (-5,5) and the other is (k,0)
sub

29= $\sqrt{(-5-k)^{2}+(5-0)^{2}}$
29= $\sqrt{(-5-k)^{2}+(5)^{2}}$
square both sides
841= $(-5-k)^{2}+(5)^{2}$
841= $(-5-k)^{2}+25$
minus 25 both sides
816= $(-5-k)^{2}$
square root both sides don't forget positive and negative roots
+/-4√51=-5-k
add 5 to both sides
5+/-4√51=-k
times -1 both sides
-5+/-4√51=k

the possible values for k are
k=-5+4√51 or k=-5-4√51

A region R in the first quadrant of the xy-plane is bounded by the curves y = x², y = 2 - x and the x-axis. Find the value of th

lions [1.4K]

The two curves meet in the first quadrant when

$x^2 = 2-x \implies x^2 + x - 2 = (x + 2) (x - 1) = 0 \implies x=1$

Then the integral in question is

$\displaystyle \iint_R x \, dA = \int_0^1 \int_{x^2}^{2-x} x \, dy \, dx \\\\ ~~~~~~~~ = \int_0^1 x (2-x-x^2) \, dx \\\\ ~~~~~~~~ = \int_0^1 (2x - x^2 - x^3) \, dx = 1 - \frac13 - \frac14 = \boxed{\frac5{12}}$
