Consider the function f(x) = 9x. which statement must be true? a) f(4) f(1) = f(8) f(5) b) f(4)·f(1) = f(8)·f(5) c) f(4) − f(1) = f(8) − f(5) d) f(4) − f(1) = f(−4) − f(−1)

The correct answer is A

Step-by-step explanation:

Exponential functions grow by equal factors over equal intervals because the change in x is always the same as the exponent of the quotient of the values of y.

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
