Hannah wanted to find the area of a square. She measured the length of the square as 3.5 cm.
Later, the actual length of the square was more accurately measured as 3.4 cm.

What is the relative error in her area calculation to the nearest hundredth?

2.86%

Step-by-step explanation:

The formula for relative error is given by:

Relative error = (Measured value - Real value)/Real value × 100

Relative error = [(3.4 - 3.5)/3.5] × 100

= -1/3.5 × 100

= 1/35 × 100

= 2.86%

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
