Answer:
y=-1/2 x-4
Step-by-step explanation:
y=mx+c
c is -4
m is rise/run so -1/2
C is a vertical angle which the vertical side is corresponding to the vertical side of x°.
105°+54°+y°=180°
159°+y°=180°
y°=21°
Meaning, x=21°.
Let's use pi
irrational times rational=irrational
pi≈3.14
so double that is
2pi≈6.28
that's beteween 5 an d7
so an irrational number between 5 and 7 is 2pi
we could also do
remember that square roots of non-perfece square numbers are usually irraitonal
5²=25
7²=49
so an irrational number could be √c where 25<c<49
example, √40
some irrational numbers are 2π nd √40
Answer:
The diameter is twice that, or approx. 7.90 units.
Step-by-step explanation:
the equation for the volume of a cylinder of radius r and height h is
V = πr²h. Here we need to calculate the diameter after having found the radius. Solving V = πr²h for r², we get:
V
r² = -----------
πh
Substituting the given values, we obtain for r² the following:
145 units³
r² = ------------------------ = 15.6 units²
3.14159(5 units)
Taking the square root of both sides, we get:
r = √15.60, or approx. 3.95 units.
The diameter is twice that, or approx. 7.90 units.
