Given 
  12 meters tall airplane
  18 meter shadow of airplane
  6 meter shadow of jet
Find the measurement of the jet (y)
Solution
 6y = 12 + 18                         30
-----    ---------    ---->     y   = -------    ----------->  y= 5
 6           6                              6

A rectangular swimming pool that is 10 ft wide by 16 ft long is surrounded by a cement sidewalk of uniform width. If the area of
Alchen [17]
We are asked to solve for the width "x" in the given problem. To visualize the problem, see attached drawing.
We have the area of the swimming pool such as:
Area SP = l x w
Area SP = 10 * 16
Area SP = 160 feet2
Area of the swimming pool plus the sidewalk with uniform width:
Area SP + SW = (10 + x) * (16 + x)
160 + 155 = 160 + 10x + 16x + x2
160 -160 + 155 = 26x + x2
155 = 26 x + x2
x2 + 26x -155= 0
Solving for x, we need to use quadratic formula and the answer is 5 feet.

The value of x is <span>5 feet. </span>

PLSSSS HELPPP&gt;&gt; Show work solve the sysytem- y=1/2x^2+4x+4 y=-4x+12 1/2
vekshin1

Answer:

The solution is (-17,80.5) and (1,8.5)

Step-by-step explanation:

Equation 1 : y=\frac{1}{2}x^2+4x+4

Equation 2: y = -4x+12.5

Substitute the value of y from equation 2 in equation 1

Equation 1 : y=\frac{1}{2}x^2+4x+4

After substitution :

-4x+12.5=\frac{1}{2}x^2+4x+4\\\frac{1}{2}x^2+8x+4-12.5=0\\\frac{1}{2}x^2+8x-8.5=0\\x^2+16x+17=0\\x=-17,2

Substitute the value of x = -17

y = -4x+12.5

y = -4(-17)+12.5

y=80.5

Substitute the value of x = 1

y = -4(1)+12.5

y=8.5

Hence the solution is (-17,80.5) and (1,8.5)
