Answer:
(1,1)
Step-by-step explanation:
Since y=x, we can say x=x^2-x+1. This means x^2-2x+1=0. x=1, y=1, thus your solution is (1,1).
Answer:
236 cm²
Step-by-step explanation:
Height of an equilateral triangle (h) = √3 /2 (l)
l = side of the equilateral triangle.
h = √3 /2 (15)
In an equilateral triangle the orthocenter, centroid, circumcenter and incenter are in the same spot
The center of the circle is the centroid and height match with the median. The radius of the circumcircle is equal to two thirds the height.
Formula for the Radius of the circumcircle = 2/3 h
= 2/3 x √3 /2 (15)
= 5 √3 cm (=radius)
Area of the circle = πr^
= 3.14 x( 5 √3 ) ^
=3.14 x(25*3)
=3.14 x 75
=235.5
=236 cm²

Answer:
The unit rate is given as $3.5 per croissant sandwiches.
Step-by-step explanation:
The total charges are $14.00
There are 4 such croissant sandwiches.
<em>The unit rate is given as, A rate is a special ratio in which the two terms are in different units. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.</em>
Thus the unit rate is given as ,
= 
Thus the unit rate is given as<em> $3.5 per croissant sandwiches.</em>
