Answer:

Step-by-step explanation:

2)  r = 16/2 = 8 cm

Area of top and bottom = 2*πr²

                                        = 2 * 3.14 * 8 * 8

                                       = 401.92 cm²

Midlle part = h * πd

                 = 6 * 3.14 * 16

                = 301.44 cm²

Total = 401.92 + 301.44

        =        703.36 cm²

3) Area of front and back = 2* \frac{1}{2}*b * h\\

                                         = 2*\frac{1}{2} * 3 * 4\\\\= 12 cm^{2}

Area of bottom = length * breadth

                           = 12* 3

                          = 36 cm²

Area of left =  12 * 4

                  = 48 cm²

Area of right = 12 * 5 = 60 cm²

Total = 12 + 36 + 48 + 60 = 156cm²

Can someone please help me understand this
Lorico [155]

Answer:

No, because one x-value corresponds to two different y-values.

Step-by-step explanation:

Given a function where x represents an input of a particular value, which gives an output for that particular value inputted as defined by the function, if the function is true and valid, a particular value of input should not give us different values of output.

Thus, from the table given, at x = 5, we have y = 3.

Also, at x = 5, we have y = 2.

Here, one x-value is given us two different y-values. This is not true if a function. We cannot regard the table given as representing a function.

Therefore, the answer is:

No, because one x-value corresponds to two different y-values.

Which equation can be used to represent the statement 16 is the same as 1 2/10 times a number added to -8 Answer choices are 16
Maksim231197 [3]

Answer:

"is the same" means there's a = sign so we know that the equation starts with 16 = ...

1 2/10 times a number added to -8 is 1.2n + (-8) so the answer is the third option.
