Answer:
x= 2
Step-by-step explanation:
so expand the left side of the equation
9x+9= 25+x
and then group like terms( subtract 9 from both sides and also do same with x.
9x-x= 25-9
8x= 16
divide by 8 on both sides.
x=2
Answer:
what are the questions ?
Step-by-step explanation:
Answer:
The maximum height of the particle is 100 ft
A is correct
Step-by-step explanation:
A particle is moving along a projectile path where the initial height is 96 feet with an initial speed of 16 feet per second.
The standard equation of parabolic projectile.
where,
So, we get the parabolic equation of path.
The maximum value at vertex.
Maximum at t=0.5
Hence, The maximum height of the particle is 100 ft
Diameter = 8 yards so the Radius = 4 yards:
Area of a sphere = 4π.R² and hemisphere = 2π.R²
Area of hemisphere = 2.π.(4)² = 32.π
But note we didn't calculate yet the are that closes this hemisphere:
Area of the cicle = π.R² = π.(4)² = 16.π, so the surface area of the hemisphere is 32π + 16π = 48.π (Or =150.8 yard²)
Answer:
A=6
Step-by-step explanation:
If the area is enclosed by x(0,4) and y(3)
That means the area is a triangle
h(height) =3 b=4 c**2=a**2+b**2 c=5
The area of an equlateral triangle is A=h*b/2
A=3*4/2=12/2
