Answer:
dA/dt = 169,56 in²/min
Step-by-step explanation:
We have a circular puddle and its area is:
A = π*r² (1) r is the radius of the circular puddle
Differentiating on both sides of the equation we get:
dA/dt = π*2*r*dr/dt (1)
In that expression we know
r = 9 inches and dr/dt = 3 in/min. Therefore plugging these values in equation (1)
dA/dt = π*2*9*3
dA/dt = 169,56 in²/min
-x means -1x that’s what it means
Answer:
Number is two
Step-by-step explanation:
First of all we find the closest factors of 864 which are 32 x 27
Simply them we have
32 x 27 = 2^5 x 3³
So
Next we know that to be aperfect cube, each exponent needs to be equally divided by divisible by 3.
So If we multiply 864 x 2 we get
Then
1728 = 2^6 x 3³
So if we finally
Take the cube root of that is 2²* 3^1 = 4 x 3= 12
So 2² x 3^1
So if we equate the powers we have the answer as 2.

Answer:
X= 10
Step-by-step explanation:
let the vertex of angle 17° named A
then the other two B and C
then by using trigonometry:
sin(A) = opposite side divided by hypotenuse
opposite side is. X
Wich makes Sin(A) = X/47
then by crossing X= sin(A) × 47 = 13.74147
rounding to the nearest tenth: X= 10
