Answer:
Volume of cylinder is 34833.21 ft³
Step-by-step explanation:
Given : A right circular cylinder having height 
ft and diameter 
times its height.
Given : diameter times its height that is
diameter times that is
Diameter = 
Diameter = 
ft
Radius is half of diameter,
Radius = 
ft
Substitute the values, we get,
Thus, volume of cylinder is 34833.21 ft³
Answer:
x>-2
Step-by-step explanation:
-9x-15<3
+15<+15 add 15 to both sides
_________
-9x<18
÷-9 <÷-9 divide both sides by -9, switch inequality _________ symbol when dividing by negative number.
x>-2 Answer
_________
Step-by-step explanation:
c² = 40² + 35² − 2(40)(35)cos(50)
c² = 1600 + 1225 − 2800 cos(50)
c² = 1025.195
c = 32.019
Graphing is used when you have paper
I will not graph this equation because it takes time, sorry
but I will solve
subsitute y=x^2+4x+1
subsitute x+1 for y
x+1=x^2+4x+1
subtract x from bot sides
1=x^2+3x+1
subtract 1 from both sides
0=x^2+3x
factor
0=(x)(x+3)
if xy=0 then assume that x and y=0
so
set them to zero
x=0
x+3=0
subtract 3 from both sides
x=-3
subsitue
y=x+1
y=0+1
y=1
y=-3+1
y=-2
so the answers could be
(x,y)
(-3,-2)
(0,1)
Answers:
- A) Definition of right angles
- B) Substitution
- C) Definition of congruence
=========================================
Explanation:
- A) The term "right angle" is another way of saying "90 degree angle". This is a definition. Think of a definition in a dictionary.
- B) The substitution property allows us to replace one thing for another, as long as the two things are equal. The transitive property works as a similar idea.
- C) If two angles have the same measure, then they are congruent. This is the definition of congruence (or one form of it).
