We know that
density=mass/volume
solve for mass
mass=density*volume
step 1
find the area of the garage door in cm²<span>
Area=300*700------> 210000 cm</span>²
step 2
find the volume of the paint
Volume=area*thick
thick=1 mm-----> 0.1 cm
Volume=210000*0.1-----> 21000 cm³
step 3
find the mass
mass=density*volume
density=1.2 g/cm³
volume=21000 cm³
mass=1.2*21000-----> 25200 grams
the answer is
25200 grams
Answer:
The function a (t) is a vector function composed of the component functions
and
. How
are infinitely derivable functions in R, so they are regular functions in R.
Now, for
, you have to
. How the functions
are periodic functions with period
the vector function
will take the same point
at
then the vector function is auto-intercepted
Step-by-step explanation:
Answer:
the two numbers are 14 and 19
Step-by-step explanation:
x + y = 33
x - y = 5 ⇒ x = y + 5
substitute x = y + 5 in x + y = 33
y + 5 + y = 33
2y + 5 = 33
2y = 33 -5
2y = 28
y = 28/2
y = 14
x = 14 + 5
x = 19
