How do the graphs of f (x) = x 2 and g (x)= 3/4 x 2? relate?
Agata [3.3K]

Answer:

g(x) is a horizontal stretch of f(x) by \frac{3}{4} units.

Step-by-step explanation:

The given functions are;

f(x)=x^2

and

g(x)=\frac{3}{4}x^2

The parent function is f(x)=x^2.

The  function g(x)=\frac{3}{4}x^2 is a horizontal stretch of  f(x)=x^2 by \frac{3}{4} units.

A scientist used a microscope to count the number of bacterial cells in a petri dish every hour. The graph shows the data collec
Alex777 [14]

The required relationship shown by the graph is the exponential relationship n =2^t . Option a is correct,

Given that,

A graph has been shown, showing the data,  what is the relationship between the number of bacteria with time is to be determined.

<h3>What is a graph?</h3>

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Since the recorded value from the graph is
At, t = 1 ; n = 2
At t = 2 ; n = 4
At t = 3 ; n = 8
At t = 4 ; n = 16
At t = 5 : n = 32
Here the above data show the exponential relation between n and t with the base value 2 i.e. n =2^t

Thus, the required relationship shown by the graph is the exponential relationship of n =2^t . Option a is correct,

Dan and Mario went to a sandwich shop to buy sandwiches for their group of friends. Dan bought 2 tuna and 5 vegetarian sandwiche
Lesechka [4]
2t+5v=37 and 4t+3v=39 

Solve the first for t

t=18.5-2.5v and use this t in the second equation...

4(18.5-2.5v)+3v=39

74-10v+3v=39

-7v=-35

v=$5.00  and since t=18.5-2.5v

t=$6.00

So tuna sandwiches cost $6.00 and vegetarian sandwiches cost $5.00.
