No because u would multiply to get a common denominator and it would be 4/6 5/6

2.) A zoo is raising a young elephant. They put him on a special high-protein diet to gain weight rapidly. He gains 6 kilograms

Elena L [17]

Answer:

The weight after 20 months is 210 kilos.

Step-by-step explanation:

1 month = 6 kilos
=> 8 months = 6 x 8 = 48 kilos
=> x + 48 = 138
=> x = 90

This means that the starting point is 90 kilos.

=> 1 month = 6 kilos
=> 20 months = 6 x 20 kilos
=> 20 months = 120 kilos
=> 90 + 120 = weight in 20 months
=> 210 kilos = weight in 20 months

Hence, the weight after 20 months is 210 kilos.

Find an equation of the plane tangent to the following surface at the given point.z equals tangent Superscript negative 1 Baseli

Sergeeva-Olga [200]

Let f(x, y, z) = z - arctan(x y). Compute the gradient of f at the point (0, 3, 0):

∇ f(x, y, z) = (-y / (1 + x²y²), -x / (1 + x²y²), 1)

∇ f (0, 3, 0) = (-3, 0, 1)

This vector is orthogonal to the surface z = f(x, y). Then the equation of the tangent plane is

∇ f (0, 3, 0) • (x, y - 3, z) = 0

(-3, 0, 1) • (x, y - 3, z) = 0

-3x + z = 0

z = 3x

Find the length of the missing side

DerKrebs [107]

Answer:

21.6 in

Step-by-step explanation:

since it's a right triangle, use the pythagorean theorem (a^2 + b^2 = c^2)

12^2 + 18^2 = c^2

144 + 324 = c^2

468 = c^2

c = square root of 468

c = 21.6333 (...) in

since you have to round it up to the nearest tenth, then the answer should be 21.6 in
