Population: six sugar maples
Sample: sap
Answer:
We need 4 litres of red paint.
Step-by-step explanation:
We need to take their respective precentages to compare the 3 litres of paint to 8 litres of paint.
Now, we know that the pale purple paint contains 50% red paint, 41.67% blue paint, and 8.33% white paint.
Now, we will transfer these percentages to the 8 litres of paint:
Answer:
(x-1)²+(y-3)²=65
Step-by-step explanation:
the common view of the equation of a circle is:
a) (x-a)²+(y-b)²=r², where (a;b) - the centre of the required circle, r - the radius of the required circle;
b) using the coordinates of the endpoint of the given diameter it is possible to calculate the coordinates of the centre of the required circle and its radius²:
the coordinate x of the required circle is: (9-7)/2=1;
the coordinate y of the required circle is: (2+4)/2=3.
the radius² of the required circle is:
r²=0.25*[(9- -7)²+(2-4)²]=0.25*260=65.
c) after the substitution the values of 'a'; 'b' and 'r²' into the common equation of the circle:
(x-1)²+(y-3)²=65.
PS. additional: the given points (9;2) and (-7;4) belong to the final equation, if to substitute their coordinates into it.
The suggested way of solution is not the only one.
Answer:
sin x = cos y
Step-by-step explanation:
sin theta = opp / hyp
cos theta = adj / hyp
First find the hyp
a^2 + b^2 = c^2 from the Pythagorean theorem
5^2+12^2 = hyp^2
25+144= hyp^2
169= hyp^2
Taking the square root of each side
sqrt(169) =sqrt(hyp^2)
13= hyp
sin x = opp / hyp=5/13
sin y = 12/13
cos x = 12/13
cos y = 5/13
sin x = cos y
