A solid metal cylinder, 8 cm in diameter and 8 cm long, is to be made into discs 4cm
in diameter and 5 mm thick. Assuming no
wastage, how many discs can be made?

answer: the value of x is 7cm

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
