Answer:

$(2x + 5) * (x^{2} + 6x - 10)\\= 2x (x^{2} + 6x - 10) + 5 (x^{2} + 6x - 10)\\= 2x^{3} + 12x^{2} - 20x + 5x^{2} +30x - 50\\= 2x^{3} + 12x^{2} + 5x^{2} - 20x + 30x - 50\\= \boxed{2x^{3} + 17x^{2} + 10x - 50}$

Hope it helps ⚜

$(2x + 5) × (x² + 6x − 10)$

$\bold\pink{↪}\small\bold\red{2x(x² + 6x − 10) +5(x² + 6x − 10)}$

$\bold\pink{↪}\bold\red{2x³ + 12x² - 20x + 5x² + 30x - 50}$

$\bold\pink{↪}\bold\red{2x³ + 12x² + 5x² - 20x + 30x - 50}$

$\bold\pink{↪}\bold\red{2x³ + 17x² + 10x - 50}$

Y=6/13X is a proportional relationship

Ivan

Answer:

x in (-oo:+oo)

Y = (6/13)*x // - (6/13)*x

Y-((6/13)*x) = 0

Y+(-6/13)*x = 0

Y-6/13*x = 0 // - Y

-6/13*x = -Y // : -6/13

x = -Y/(-6/13)

x = 13/6*Y

An airplane is flying at a speed of 500 mi/h at an altitude of one mile. The plane passes directly above a radar station at time

d1i1m1o1n [39]

Answer:

a) $s=\sqrt{1+d^2}$

b)d(t)=500t

c) $s(t) =\sqrt{1+250000t^2}$

Step-by-step explanation:

d = Horizontal distance

s = the distance between the plane and the radar station

The horizontal distance (d), the one mile altitude, and s form a right triangle.

So, use Pythagoras theorem

$Hypotenuse^2=Perpendicular^2+Base^2$

$s^2=1^2+d^2$

a) $s=\sqrt{1+d^2}$

(b) Express d as a function of the time t (in hours) that the plane has flown.

$distance = speed \times time$

d(t)=500t

$s(t) =\sqrt{1+d^2}$

using b

$s(t) =\sqrt{1+(500t)^2}\\s(t) =\sqrt{1+250000t^2}$
