Write an expression in simplest form that represents the total amount in each situation.

vampirchik [111]

Answer:

T = 18x + 25

Step-by-step explanation:

Let T = total amount in $

x amount of tents at $10 each (10x)

same amount of tables for $8 each (+8x)

one clown for $25 (+25)

so T = 10x + 8x + 25

T = 18x + 25

If f(x) = kx^3+ x^2 − kx + 2, find a number k such that the graph of f contains the point (k, -10)

Elina [12.6K]

If we write $k$ where we see $x$ in the equation and set the result equal to $-10$ , we get the result.

$f(k)=k(k)^3+k^2-k(k)+2$
$=k^4+k^2-k^2+2$
$=k^4+2=-10$
$k^4=-12$
$k_{1}=\sqrt[4]{3}(-1-i)$
$k_{2}=\sqrt[4]{3}(-1+i)$
$k_{3}=\sqrt[4]{3}(1-i)$
$k_{4}=\sqrt[4]{3}(1+i)$

A flight from Boston to London took only 5 hours because of a strong tailwind. The flight back to Boston against the same wind t

Nata [24]

Step-by-step explanation:

let v is the speed of the wind,

the equation of the speed:

(550 + v ) × 5 = (550 - v) × 6

2750 +5v = 3300 - 6v

11v = 3300 - 2750

11v = 550

v = 550/11

v = 50

therefore, the speed of the wind =

50 mph
