Answer:

Step-by-step explanation:

1.

a)

Find the vertex by completing the square to answer both a and b

d)

x-ints is when y=0

so use quadratic equation for

b^2-20b+200=0

a=1

b= -20

c=200

But notice these imaginary numbers means 0 x intercepts.

The volumes of two similar solids are 729 inches3 and 125 inches3. If the surface area of the smaller solid is 74.32 inches2, wh
tangare [24]
This is the concept of scales factors, given that two similar solids with 729 inches^3 and 125 inches^3. The volume scale factor will be given by:
(volume of larger solid)/(volume of smaller solid)
=729/125
but
linear scale factor=(volume scale factor)^1/3
thus the linear scale factor will be:
(729/125)^1/3
=9/5
Also, area scale factor will be given by:
area scale factor=(linear scale factor)^2
=(9/5)^2
=81/25
The area of the larger solid will be given by:
let the area be A;
A/74.32=81/25
thus
A=81/25*74.32
A=240.7968 inches^2

X¾(√y/x)y⅝=x^my^n, find n^m
Blababa [14]

Hooke's law says that the force produced by a spring is proportional to the displacement (linear amount of stretching or compressing) of that spring:

F = -kx

where k is called the force constant or spring constant of the spring. Each spring has its own force constant.

The diagram defines all of the important dimensions and terms for a coil spring. For each mass hung on it (the mass could be zero), a spring has some natural length, at which it is neither compressed (shortened) or extended (lengthened). At that point, the upward force produced by the spring is exactly balancing the gravitational force on the mass and spring (remember that the spring itself has mass).

We define the coordinate x so that it is negative when the spring is compressed, zero at the natural length and positive when the spring is extended. The minus sign in F = -kx is there by convention; we think of F as the restoring force. When the spring is compressed, a positive force is required to extend it, and when it is extended, a negative force is required to shorten it, or restore it to its natural length.

If the spring is strong or stiff, k will be large, and k will be small for a weak spring.

Hooke's law is applicable not only to coil springs like the one shown here, but also to the bending of metal and some other materials, the stretching of wires like guitar strings, the stretching of rubber bands, and the stretching and compressing of chemical bonds.

obsidan is another type of igneous rock what is the density of a obsidian that has a mass of 239.2 and a volume of 92
horsena [70]
The answer is .426 or .43 depending on what you round to. The equation for density is

D=m/v so D= 239.2/92 will give you the answer to your problem.
