ANSWER
The circumcenter is (2,1)
EXPLANATION
The midpoint of BC is (-3,2)
The equation of the perpendicular bisector of BC is x=2
The midpoint of AB is (-1,1)
The midpoint of AB is (-1,1)
The perpendicular bisector of AB is y=1.
These two lines intersect at (2,1).
The point of intersection of the perpendicular bisectors of a triangle is called the circumcenter of the triangle.
The correct question is
Use calculator to find √(<span>68.1) to the nearest hundredth
we know that
T</span><span>o the nearest 'hundredth' is the same as saying </span>
<span>'Round off to two decimal places
</span><span>To do this you first have to determine the answer with a calculator to at least 3 decimal place
</span>√68.1-------> 8.252
The rounding will happen at the 5. It will either stay 5 or round up to 6, depending on the next digit which is a 2.
<span>The 2 is below 5, so the answer rounds down to give 8.25
</span>
the answer is
8.25
Answer:
2878
Step-by-step explanation:
Let "abcd" represent the digits of the number.
a ≠ 0
"The sum of the digits is 25"
a+b+c+d = 25
"The smallest digit is in the largest place"
a < b, c, d
"The largest digit is used twice but not side by side"
The digits of the number are "abcb"
b > a, c
"The smallest digit is ¼ as large as the largest digit"
a = b/4
b = 4 or 8
If b = 4, then a = 1 and c = 25 - a - 2b = 16, which is not a single digit. ∴ b ≠ 4
b = 8
a = b/4 = 2
2+8+c+8 = 25
c = 7
The number is 2878.
