The sides of a triangle have lengths 2x + 2, 4x, and 5x + 1. The longest side of the triangle has a length of 5x + 1. For what v
Savatey [412]

Answer:

Step-by-step explanation:

(5x+1)²>(2x+2)²+(4x)²

25x²+10x+1>4x²+8x+4+16x²

5x²+2x-3>0

5x²+5x-3x-3>0

5x(x+1)-3(x+1)>0

(x+1)(5x-3)>0

x+1=0,gives x=-1

5x-3=0,gives x=3/5

x >0(because 4x should be >0)

side is always positive.

so x>3/5

again 5x+1<2x+2+4x

5x-6x<2-1

-x<1

x>-1

x=all real values >3/5

a physics student stands at the top of a hill that has an elevation of 56 meters. He throws a rock and it goes up in the air and
babunello [35]
The answer is 57.04 meters. 
Solution:
The height y of the rock above the ground as a function of the horizontal distance x from the starting point on top of the hill can be modeled by the equation 
     y = -0.04x^2 + 1.3x + 56

We now set this equation equal to zero because the height of the ground where the rock will land is zero:
     0 = -0.04x^2 + 1.3x + 56

Since we have a quadratic equation, we can calculate for the horizontal distance x by using the quadratic formula     
     x = [-b ± sqrt(b^2 - 4ac)] / 2a      
     x = {-1.3 ± sqrt[1.3^2 - 4(-0.04)(56)]} / 2(-0.04)     
     x = (-1.3 ± sqrt(10.65)) / (-0.08)     
     x =  -24.54 meters or  57.04 meters
There are two solutions for x but one is negative, so we choose the positive value.
