Use the substitution method

f(x)= -10x+16

f(-7)= -10(7)+16

Mutiply first then add because of PEMDAS

P= parenthesis

E= exponents

M= multiplication

A= addition

S= subtraction

-70+16= -54

Answer : f(-7)= -54

A metal cube contracts when it is cooled. if the edge of the cube is decreasing at a rate of 0.2 cm/hr, how fast is the volume c
aleksandr82 [10.1K]

Answer:

2160 cm³/hour

Step-by-step explanation:

By default, we know that the volume of a cube is given as s³

Thus, the Volume function, V = s³

When we differentiate with respect to time we have

dV/dt = 3s² (ds/dt), where ds/dt = 0.2

Then we go ahead and substitute all the given parameters

dV/dt = 3 x 60 x 60 x 0.2

dV/dt = 10800 * 0.2

dV/dt = 2160 cm³/hour

This means that the volume decreases by a rate of 2160 cm³/hour at the instant its edge is 60 cm

What is the volume in cubic feet of a rectangular prism with a height of 8ft and width of 8ft and a length of 18th feet.
Hitman42 [59]

The volume of the rectangular prism is 1152 cubic feet (ft^{3}), If the rectangular prism have height of 8 feet and width of 8 feet and a length of 18th feet.

Step-by-step explanation:

              The given is,

                       Let, h - Height of the rectangular prism

                              w - Width of the rectangular prism

                                l -Length of the rectangular prism

Step:1

            From the given,

                              h = 8 feet

                              w = 8 feet

                               l = 18 feet

Step:2

          Formula for volume of Rectangular prism is,

                     V = whl

        Substitute the values of w, h and l,

                     V = ( 8 × 8 × 18 )

                        = 1152

                    V = 1152 cubic feet

Result:

           Thus the volume of the rectangular prism is 1152 cubic feet (ft^{3}), for the given rectangular prism have height of 8 feet and width of 8 feet and a length of 18th feet.
