If you use the 365 days

first you multiply 365x24

there are 8760 hours in a year

then it is 365x7= 2555

8760-2555

you are awake 6205 hours

The density of a certain type of paint is 1.2 grams per cubic centimeter. A garage door that is 3 meters tall and 7 meters wide
Naily [24]
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

Prove that the curve a(t) = (cost, sin 2t, cos 2t) is regular on R and that it self-intersects at (1,0,1). Check the self-inters
alexandr402 [8]

Answer:

The function a (t) is a vector function composed of the component functions a_ {1} (t) = cost, a_ {2} (t) = sin2t and a_ {3} (t) = cos2t. How a_ {1} (t), a_ {2} (t), a_ {3} (t) are infinitely derivable functions in R, so they are regular functions in R.

Now, fort = 0, you have to a (0) = (cos (0), sin2 (0), cos2 (0)) = (1, 0, 1). How the functions a_ {1} (t), a_ {2} (t), a_ {3} (t) are periodic functions with period 2 \pi, the vector function a (t) will take the same point (1, 0 , 1) at t = 2n\pi, n = 0, 1, 2, 3, ... then the vector function is auto-intercepted

One number is 5 more than the other. Their sim is 33. Find the answer
disa [49]

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
