(sin30°+cos60°) (tan60°-sec30°)<br>

olga_2 [115]

Answer:

$\frac{ \sqrt{3} }{3}$

Step-by-step explanation:

$(sin30 + \cos(60) )( \tan(60) - \sec(30)$

$( \frac{1}{2} + \frac{1}{2} )( \sqrt{3} - \frac{2 \sqrt{3} }{3})$

$(1)( \sqrt{3} )$ over 3

$= \frac{ \sqrt{3} }{3}$

A tennis ball bounces based on this equation y = x2 - x+2. A dog jumps based on this equation y=2x.

valentina_108 [34]

Answer: when the equations are equal, that is when x = 1 or x = 2

Step-by-step explanation:

The dog will receive the ball , when both equations intercept , that is , when both equations are equal. This implies :

$x^{2}$ - x + 2 = 2x

$x^{2}$ - x - 2x + 2 = 0

x(x-1) - 2 (x - 1 ) = 0

(x - 1 ) ( x - 2 ) =0

Therefore , x = 1 or x = 2
