Hello,
When you compose 2 reciprocals functions, you will find 1.
ex f(x)=√x and g(x)=x² , x>=0
so that g(f(x))=(√x)²=x
sin(cos(0))=sin(1)=0,84147... rad and not 1.
Reciprocal function of sin (x) is arcsin(x).
Reciprocal function of cos (x) is arccos(x).
Y=40x + 225
Because x is your per hour cost.
Answer:
Mean: 1.5
Standard Deviation: 0.9
Step-by-step explanation:
2/3 of the pages have diagrams, and N is the number of pages Harlee reads to reach a page with a diagram. In order to find the mean, divide 1/(2/3) to get 1.5 as your mean, and then divide sqrt(1-(2/3))/2/3 to get .8660, which rounds to .9.

Answer:300,000
Step-by-step explanation: if the 4 was a 5 or higher then the answer would’ve been 400,00 but since the number next to the underlined digit is 4 then it goes to 300,00. (4 or below leave it alone 5 or above give it a shove)
