Answer: A
Step-by-step explanation:
So there needs to be roots at x=-2, 0, and 3.
Also, the end behavior needs to approach infinity as x approaches infinity and negative infinity as x approaches negative infinity (since the leading coefficient is positive). This rules out the last option.
Now, we can also use the fact that the maximum number of turning points is one less than the degree, for a maximum of 2 turning points. This rules out the middle option as well.
Answer:
a.
b.
Step-by-step explanation:
Volume of the container denotes its quantity. It is a three-dimensional space.
Let V denotes the volume of the container, h denotes the height of the container and r denotes the radius of the container.
a.
The total capacity of the container in terms of π is <u />
b.
As the cylindrical container is four-fifths full of powder, so the volume of the powder in terms of π is volume of the container i.e.,
Answer:
Hence after 3.98 sec i.e 4 sec Object will hit the ground .
Step-by-step explanation:
Given:
Height= 6 feet
Angle =28 degrees.
V=133 ft/sec
To Find:
Time in seconds after which it will hit the ground?
Solution:
<em>This problem is related to projectile motion for objec</em>t
First calculate the Range for object and it is given by ,
(2Ф)/
Here R= range g= acceleration due to gravity =9.8 m/sec^2
1m =3.2 feet
So 9.8 m, equals to 9.8 *3.2=31.36 ft
So g=31.36 ft/sec^2. and 2Ф=2(28)=56
fts
Now using Formula for time and range as
Vx is horizontal velocity
Ф
(28)
ft/sec
So above equation becomes as ,
T is approximately equals to 4 sec.
