For the given number a. find it’s additive inverse and b. find its absolute value. 7.87 a. the additive inverse of 7.87 is ? ?

a) -7,87

b) 7.87

Step-by-step explanation:

The sum of a real number and its additive inverse gives the identity element of addition which is zero.

Let x be the additive inverse of 7.87 then

This implies that:

The absolute of a real number is its distance from zero on the real number line.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
