Answer:
Step by step explanation:
Given that,


Solution:
Solving for (f•g)(x):

Now substitute the given values.


Apply distributive property:

Hence,f•g(x) will be
.
14.14 inches
Convert 135° into radians. 135*2pi/360=3pi/4.
6*3pi/4=18pi/4=9pi/2=14.14
Another viable method is to do 2pi*6*135/360=14.14
Answer:
240 m³
Explanation:
The volume of a pyramid is equal to:

Where B is the area of the base and H is the height of the pyramid.
Then, the base of the pyramid is a triangle, so the area of a triangle is equal to:

Where b is the base of the triangle and h is the height of the triangle. So, replacing b by 16 m and h by 9 m, we get:

Finally, replacing B by 72 m² and H by 10 m, we get that the volume of the pyramid is equal to:

Therefore, the volume is 240 m³
Answer:
distance = 5
Step-by-step explanation:
Use Pythagorean Theorem or Distance Formula (which comes from Pythagorean Thm anyway) see image.
Answer:
42 degrees
Step-by-step explanation:
48 and r are equal.
The box means right angle, or 90 degrees
180-90-48=42 degrees
