Answer:
The number of points scored by each game is 9
Step-by-step explanation:
The number of points scored in each game given by the equation
x - 7 = 2
x = 2 + 7
x = 9
The total surface area of a regular tetrahedron is calculated through the equation,
SA = (sqrt 3) x a²
Substituting the known value,
SA = (sqrt 3) x (10 cm)² = 173.20 cm²
Its volume is obtained by,
V = ((sqrt 2)/ 12) x a³
V = ((sqrt 2) / 12) x (10 cm)³ = 117.85 cm³
Thus, its surface area and volume are 173.20 cm² and 117.85 cm³, respectively.
Answer:
d y dx=0
Explanation:
From the given
y=sin2x+cos2x
The right side of the equation is
=1
y=1
d y d x=d d x(1)=0
or we can do it this way.
y = sin2x+cos2x
d y d x=2
⋅(sinx)2−1
⋅
d d x(sinx)+2
(cosx)2−1 d d x(cosx)
d y d x=2⋅
sinx⋅cosx+2⋅cosx⋅(−sinx)
dydx=2⋅sinx⋅cosx−2⋅sinx⋅cosx
dydx=0
God bless....I hope the explanation is useful.
