Consider the following.f(x)=74 – x2Find the x-values at which f is not continuous. Which of the discontinuities are removable?
tensa zangetsu [6.8K]

Answer

given,

f(x) = 74 - x²

A function is continuous when it is differential at all the points.

f'(x) =\dfrac{d}{dx}(74-x^2)

f'(x) =- 2 x

so, the given function is continuous for all the value of x.

We should know that if a function is quadratic then it is differential at all the point.  And if it is differential then it is definitely continuous.

Hence, there is no discontinuous point present in the equation.

What is the surface area of this triangular prism?
konstantin123 [22]

Answer:

surface area = 136 m^2

Step-by-step explanation:

The prism has 5 faces.

Faces 1 and 2: The front and back faces are two congruent triangles with base 6 m and height 4 m.

Face 3: The bottom face is a rectangle with length 7 m and width 6 m.

Faces 4 and 5: The left and right inclined faces are two congruent rectangles with length 7 m and width 5 m.

area = area of faces 1 and 2 + area of face 3 + area of faces 4 and 5

area of triangle = bh/2

area of rectangle = LW

area = 2 * 6 m * 4 m / 2 + 7 m * 6 m + 2 * 7 m * 5 m

area = 24 m^2 + 42 m^2 + 70 m^2

area = 136 m^2

Answer: surface area = 136 m^2
