Given:
The function is:

This function is stretched by a factor of 9 to g(x).
To find:
The equation of function function g(x).
Solution:
The vertical stretch is defined as:
...(i)
If
, then the function f(x) compressed vertically by factor k.
If
, then the function f(x) stretched vertically by factor k.
The given function f(x) is stretched by a factor of 9 to g(x). So the value of k is 9.
Substituting
in (i), we get

![[\because f(x)=x^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20f%28x%29%3Dx%5E2%5D)
Therefore, the required function is
.
Answer: Experimental study
Step-by-step explanation:
This is an experimental study because it involves determination of the effect of each treatment on separate individuals. It involves selecting the 81 individuals randomly to be treated with a particular treatment (either of the two treatment). In experimental study the researcher apply separate treatments on a different groups and measure its effect on each of the groups.
Answer:
Step-by-step explanation:
The 9 in 95 tells us how many tens are in the number 95.417; the 5 tells us how many ones, and the 4 how many tenths. And so on.
Thus,
95.417 = 9*10^1 + 5*10^0 + 4*10^(-1) + 1*10^(-2) + 7*10^(-3)
is 95.417 in expanded form, with each digit multiplying a power of 10.
Answer:
x = 40
Step-by-step explanation:
2/5x + 1/4x = 26
~Find common denominators
8/20x + 5/20x = 26
~Combine like terms
13/20x = 26
~Multiply 20/13 to both sides
x = 40
Best of Luck!
