Answer:

-1333/1000

Step-by-step explanation:

Evaluate tan(sin^-1(-4/5)).

First we need to evaluate the expression in parenthesis

sin^-1(-4/5)

= sin^-1(-0.8)

= -53.13

SUbstitute the given value into the original expression as shown;

tan(sin^-1(-4/5))

= tan(-53.13)

= -1.333

= -1333/1000

Hence the required answer is -1333/1000

The standard form of -36/34

shepuryov [24]

Assuming that you mean "simplified form", we have to cancel every common divisor of both numerator and denumerator.

36 is factored as $2^2\cdot 3^2$

34 is factored as $2\cdot 17$

So, the two numbers only have a factor 2 in common, meaning that the simplified form of this fraction is

$-\dfrac{18}{17}$

Answer: 9000$

Step-by-step explanation:

Let 's use the formula to find the vertex of the parabola:

ax²+bx+c=0

$\displaystyle x_v=-\frac{b}{2a} \\\\ Where :\\\\ y_v- maximum \ \ income \\\\ y_v=a(x_v)^2+bx_v+c \\\\ Then \ in \ \ our \ \ case : \\\\ -4p^2+1200p =0 \\\\ x_v=-\frac{1200}{-4\cdot 2} =150 \\\\ y_v=-4\cdot (150)^2+150\cdot 1200 \\\\ y_v=150\cdot 1200-150\cdot 600 \\\\ y_v=600\cdot 150=\bf 9000 \$
