It is 1 bc u just look at the x. If there was a number before it, that would be the slop, but because there is no number x is 1x.

A function is shown f(x) = 2/3x +3 what is the value of f (6)?
Katena32 [7]

Answer:

The answer is 28/9

Step-by-step explanation:

Step one

Given information

We are given that the function is

f(x) = 2/3x +3

And we are expected to find f(6), that is substitute the value of x with 6

Step two:

f(6)= 2/3(6)+3\\\\f(6)=2/18+3\\\\f(6)=1/9+3\\\\f(6)=1+27/9\\\\f(6)= 28/9

The function f(x) = 7(1.32)x models the number, in billions, of the DNA sequences in a database x years since 2010. What does th
NikAS [45]

Answer:

The correct option is (A).

Step-by-step explanation:

The function representing the growth of number, in billions, of the DNA sequences in a database x years since 2010 is:

f(x)=7\cdot (1.32) x

The general growth function can be represented as:

y=a\cdot (1+r)^{t}

Here,

<em>y</em> = final value

<em>a</em> = initial value

<em>r</em> = growth rate

<em>t</em> = time

Com-paring the two functions we get:

1+r=1.32\\r=1.32-1\\r=0.32

This implies that the annual increase rate in number, in billions, of the DNA sequences is 32%.

Thus, the correct option is (A).

nikklg [1K]

Answer:

10.6 cm to the nearest tenth.

Step-by-step explanation:

If we let one side = x. So as each side of a square are equal, and using Pythagoras we have:

x^2 + x^2 = 15^2

2x^2 = 225

x^2 = 112.5

x = √112.5

x = 10.61.
