Answer:
(a)
if 
then 
and if x<0 then 
(b)
That is straightforward from what you showed on theorem 3.25
(c)
Following the same ideas from (a) x>a or -x > a.
Step-by-step explanation:
Remember how we define the absolute value of a number.
(a)
In general
Therefore if 
you have two cases, if then and if x<0 then
(b)
That is straightforward from what you showed on theorem 3.25
(c)
Following the same ideas from (a) x>a or -x > a.
59.9 = 23.2 + 17.1 + 2*leg = Perimeter
2 * leg = 19.6
each leg = 9.8 meters
Answer:
Step-by-step explanation:
A cone is a three-dimensional closed figure that has a circular base connected to a vertex (or apex) point outside the plane of the base. Similar Cross Sections. (parallel to base) • The one and only base of the cone is a circle (or other curved figure).
Solution:
We have: In the attached image, observe rectangle triangle ΔBAD
Use the Pythagorean Theorem:
BD = √(AB² + AD²)
BD = √(2² + 4²)
BD = √(4 + 16)
BD = √20
In the attached image, observe rectangle triangle ΔBDH
Use the Pythagorean Theorem:
BH = √(BD² + DH²)
BH = √(√20² + 5²)
BH = √(20 + 25)
BH = √45
BH = √(9 × 5)
BH = √9 × √ 5
BH = 3√5
BH = 3 × 2.24
BH = 6.72 cm
