Answer:

(a) 3.96

Step-by-step explanation:

Corresponding sides of similar triangles have the same ratio.

ratio of bottom sides = ratio of right sides

x/6 = 3.3/5

Multiplying by 6 gives ...

x = 6(3.3/5) = 3.96 . . . . matches the first choice

<em>Additional comment</em>

It is always a good idea to check your answer for reasonableness. Here, we notice the bottom side of ΔABC is longer than the right side. That means the value of x will be more than 3.3. (eliminates choices B and D)

The difference in lengths of the sides of triangle ABC is 6-5 = 1, which is 1/5 the length of the right side. That means the difference between x and 3.3 will be about 3.3/5 = 0.66. The length 5.12 is way too much for the value of x. The value of x will be 3.3 +0.66 = 3.96.

Which is the range of the function f(x) = (9)×?

Anna [14]

Using it's concept, it is found that the range of the function $f(x) = 9^x$ is given by:

all real numbers greater than 0.

<h3>What is the range of a function?</h3>

It is the set that contains all possible output values for the function.

In this problem, the function is:

$f(x) = 9^x$

For <u>exponential functions without vertical shifts</u>, as is the case in this problem, the range is given by:

all real numbers greater than 0.

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:Domain = [-9, -1]$

$\qquad \tt \rightarrow \:Range = [-1 , 3]$

____________________________________

$\large \tt Solution \: :$

Domain = All possible values of x for which f(x) is defined

[ generally the extension of function in x - direction ]

Range = All possible values of f(x)

[ generally the extension of function in y - direction ]

$\large\textsf{For the given graph : }$

$\qquad \tt \rightarrow \: domain = [ - 9, -1]$

$\qquad \tt \rightarrow \: range= [ -1,3]$

Figure out slope by using:
(y2-y1)/(x2-x1)

Plug in values:
29.98-15.49/50-25

Simplify:
14.49/25 = 0.5796

Then, use this ratio for the 40 lbs bag. So, then:
40*0.5796 = 23.184

So, your price for the 40 lbs bag should be $23.18 because cents only go up to 2 decimal places (otherwise, it would be $23.184).
