the length of a rectangular piece of land is 12cm more than four times its width. the perimeter is 74cm. find its dimensions
Marysya12 [62]

length = 32 and width = 5

let the width = w then length = 4w + 12

perimeter = 2 ( length + width )

               = 2( 4w + 12 + w ) = 2( 5w + 12 ) = 10w + 24

perimeter = 74

solve 10w + 24 = 74

subtract 24 from both sides

10w = 74 - 24 = 50 ⇒ w = 5

width = 5 and length = (4 × 5) + 12 = 20 + 12 = 32

Use the upper and lower sums to approximate the area of the region using the given number of subintervals (of equal width). (Rou
natita [175]

Answer:

The answer to this question can be defined as follows:

The Lower sum ="0.659"

The Upper sum ="0.859"

Step-by-step explanation:

In the given equation there is some mistype error, so the correct equation and its solution can be defined as follows:

Equation:

y= \sqrt{1-x^2}

calculating the Δx:

=\frac{(1 - 0)}{5}\\\\=\frac{1}{5}

calculating the Upper sum value:

=\bigtriangleup x  \times (f(0) + f(\frac{1}{5}) + f(\frac{2}{5}) + f(\frac{3}{5}) + f(\frac{4}{5})) \\\\= \frac{1}{5} \times  (1 + \sqrt{(\frac{24}{25})} + \sqrt{\frac{21}{25}} + \frac{4}{5} + \frac{3}{5})\\\\= 0.859

calculating the Lower sum value:
