Answer:
The 2nd one
Step-by-step explanation:
Basically think of the original image increasing in size, so it cant change in anyway, as in the angles are are proportional. So just look at the original image, and look for the one that looks exactly the same, just the size increased.
(It would be an enlargement btw)
Hopefully this helps:))
7. Subtract 5.7 from both sides to get the variable on one side. (f=2)
8. Subtract 5.52 from both sides to get the variable on one side. (f=5)
9. Add 3.77 to both sides so the variable will be on one side.
10. Add 10.58 to both sides.
11. Divide by 2.2 on both sides. 2.2b/2.2 will leave you with the variable b. 8.8/2.2=4; b=4.
12. Divide by 2.5b on both sides. 2.5b/2.5 leaves b. 10/2.5= 4; b=4.
Answer:20.39
Step-by-step explanation:
Answer:
f(x)=3x5 is both monomial function, power function
Step-by-step explanation:
Monomial function is one which has only one term that is non-zero term.
example
b is a monomial with one variable
5xy^2 is a monomial with two variable
10x^10 is a monomial with one variable.
_______________________________________
power function is one which consist of a coefficient, a variable and that variable is raised to some non-zero power.
example
2x^6
area of circle =
_____________________________________
given function
f(x)=3x5
1. it has only one non zero term thus qualifies to be called monomial
2. It has a coefficient 5, a variable x and that x is raised to some non-zero power 5. Thus, it is a power function as well.
Answer: We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.
Step-by-step explanation:
Given : Significance level :
Sample size : n= 52 , which is a large sample (n>30), so we use z-test.
By using z-value table,
Critical value:
Sample mean :
Standard deviation :
The confidence interval for population means is given by :-
i.e.
Now, the 95% confidence interval for the ppopulation mean = . (29.0813, 40.0187)
Hence, We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.
