Answer:

Perimeter: 20, Area: 21

Step-by-step explanation:

Based on points (2,6) and (5,6) : w = 5 - 2 = 3
Base on points (5,6) and (5,-1 ): l = 6 - (-1) = 7

Perimeter: 2 x (3 + 7) = 20
Area: 3 x 7 = 21

You place the spring vertically with one end on the floor. You then drop a book of mass 1.50 kg onto it from a height of 0.900 m

Alex777 [14]

Answer:

The value of the maximum distance the spring will be compressed

x = 0.143 m= 14.3 cm

Step-by-step explanation:

Given data

Mass m = 1.5 kg

h = 0.9 m

k = 1500 $\frac{N}{m}$

Since the book is released from a height h = 0.9 m above the top of the spring. so the total distance

y = h + x

Now in that case for the spring

$mg y= \frac{1}{2} k x^{2}$

$mg(h +x) = \frac{1}{2} k x^{2}$

By rearranging the above equation we get

$k x^{2} - 2mgx - 2mg h = 0$

Put all the values in above equation we get

$1500x^{2} - 29.43 x - 26.48 = 0$

By solving the above equation we get

x = 0.143 m= 14.3 cm

This is the value of the maximum distance the spring will be compressed.

Find the area in the right tail more extreme than z= 3.01 in a standard normal distribution

Feliz [49]

<span>The area in the right tail more extreme than z= 3.01 in a standard normal distribution is given by
