Answer:
True
Step-by-step explanation:
The circumcenter is the center of the circumscribing circle, the circle that intersects each of the vertices. Since the points on a circle are equidistant from its center, the vertices of a triangle are equidistant from the circumcenter.
Answer:
Speed of hikers are 4.4 mph and 7.7 mph
Step-by-step explanation:
Two hikers are 55 miles apart and walking towards each other.
They meet after 10 hours.
Let the speeds of hikers are S and S' mph.
One hiker walks 3.3 mph faster than the other,
S = 3.3 + S'
S' = S - 3.3
Distance traveled by the hiker with higher speed S = Speed × Time
Distance traveled by the slower hiker 
= (S - 3.3) × 10
Total distance between them = 55 miles
10S + 10(S - 3.3) = 55
20S - 33 = 55
20S = 88
S = 4.4 mph
Speed of first hiker = 4.4 mph
Speed of second hiker = 4.4 + 3.3 = 7.7 mph
Answer:
-1/cd
b = -a/cd
Step-by-step explanation:
a = -bcd
Multiplication and division are inverse operations
Multiply each side by -1/cd
a* -1/cd = -bcd * -1/cd
-a /cd = b
Answer:
iydjtulsulyzursrusutxulsr
Step-by-step explanation:
2y=6
Solve the equation for y using the formula for slope: y + mx + b
2x^2 + 5y^2 = 14
5y^2 = -2x^2 + 14
y^2 = -2/5x^2 + 14/5
y = the sq root of -2x^2/5 + 14/5
There is no integer solution to the square root of a negative number.
