A rectangular plot of land that contains 1500 square meters will be fenced and divided into two equal portions by an additional

photoshop1234 [79]

Let the length be x and the width be w

The perimeter will be:
2x+3w=1500

thus
3w=(1500-2x)
w=(1500-2x)/3
w=500-2/3x

The area will be:
A=x*w
A=x(500-2/3x)
A=500x-(2/3)x²

The above is a quadratic equation; thus finding the axis of symmetry we will evaluate for the value of x that will give us maximum area.

Axis of symmetry:
x=-b/(2a)
from our equation:
a=(-2/3) and b=500
thus
x=-500/[2(-2/3)]
x=375
the length will be 375 m

The width will be 250 m

Micah's gym is moving into a bigger space, where he can have more stationary bicycles and treadmills. Micah needs both stationar

marin [14]

Answer:

Options (2), (3), (5) and (6)

Step-by-step explanation:

Let the number of bicycles = x

and the number of treadmills = y

Since, number of new bicycles must be more than $\frac{1}{3}$ times of new treadmills,

Inequality representing the statement will be,

x > $\frac{1}{3}$ y

Each bicycle costs $340 and each treadmill costs $670.He must spend less than $5650,

Inequality will be,

340x + 670y < 5650

And the number of bicycles and treadmills should be greater than 0.

x > 0

y > 0

Therefore, constraints for this situation are,

Option (2)

Option (3)

Option (5)

Option (6)

Answer:

first calculate the area of the arch using:

O/360×πr2

O represents theta

second calculate the area of the circle using πr2

finally minus the answer gotten from the two different areas

thats how u get the area of the shaded area
