Answer:

$x=1$

Step-by-step explanation:

$\frac{3}{4}(12x-8)+3=10-\frac{1}{2}(6x+2)$

$(9x-6)+3=10-(3x+1)$

$9x-6+3=10-3x-1$

$9x-3=9-3x$

$9x=12-3x$

$12x=12$

$x=1$

Prove that there exists a unique real number solution to the equation x3 + x2 − 1 = 0 between x = 2/3 and x=1

ziro4ka [17]

Replace each of the x values given to see if they give 0.

0=(2/3)³+(2/3)²-1
0=(8/27)+(4/9)-1
0≠-0.259

0=(1)³+(1)²-1
0≠1

Therefore, you can see that the solution would have to be between 2/3 and 1.

Hope I helped :)

A woman walks due east on the deck of a ship at 4 mi/h. the ship is moving south at a speed of 24 mi/h. find the speed of the wo

grandymaker [24]

we are given

A woman walks due east on the deck of a ship at 4 mi/h.

the ship is moving south at a speed of 24 mi/h

so, firstly, we will draw diagram

so, we have

$OW=4$

$OS=24$

now, we can use Pythagoras theorem

$SW^2=OS^2+OW^2$

now, we can plug values

and we get

$SW^2=24^2+4^2$

$SW=24.33$

so,

the speed of the woman relative to the surface of the water is 24.33 mi/h .......Answer
