Find the dimensions of the rectangle
hoa [83]
(a) The sum of length and width is half the perimeter, so the breadth in terms of length (x) in cm will be
.. breadth = 34 -x


(b) Then the expression for the area (in cm^2) is
.. area = length*breadth
.. 253 = (x)(34 -x)
.. x^2 -34x +253 = 0 . . . . . subtract the right side, eliminate parentheses
.. (x -11)(x -23) = 0 . . . . . . . factor
.. x = 11 or 23

The dimensions of the rectangle are 11 cm by 23 cm.

HELP I WILL GIVE BRANNIEST
krek1111 [17]

Answer:

0.75s , 15ft

Step-by-step explanation:

Use Derivatives,

Notice that the above function is a quadratic curve, meaning it has either a maximum or minimum point, which is the turning point and that is what we are solving for to find a 'max' or 'min'.

\frac{d}{dt}h = \frac{d}{dt}(-16t² + 24t + 6)

\frac{dh}{dt} = -32t + 24

At turning points (max/min),

the gradient is 0 meaning,

\frac{dh}{dt} = -32t + 24 = 0.

t = 24/32 = 3/4

so time = 0.75 second

Substitute this t into the function,

we get h = -16 * 0.75 *0.75 + 24 * 0.75 + 6 = 15ft

2=2 (lw+lh+wh) solve for w
kirza4 [7]
Solve for w.

2=2(lw+lh+wh)

Flip the equation.

2hl+2hw+2lw=2

Add -2hl to both sides.

2hl+2hw+2lw+−2hl=2+−2hl

2hw+2lw=−2hl+2

Factor out variable w.

w(2h+2l)=−2hl+2

Divide both sides by 2h+2l.

w(2h+2l) / 2h+2l=−2hl+2 / 2h+2l

w=−hl+1/h+l
