Answer:
A baseball diamond is a square with sides of 90 feet. What is the distance to the nearest tenth of a foot between home and second base?
Step-by-step explanation:
127.3 feet This problem requires the use of pythagoras theorem. Ignore the face that it's a baseball diamond. All you're concerned with is that you have a square that's 90 feet per side and you want to know what the length of the diagonal. So you have a right triangle with 2 sides of 90 feet each and you want to know the length of the hypotenuse. The formula is C^2 = A^2 + B^2 Both A and B are 90, so plugging them into the formula gives C^2 = 90^2 + 90^2 = 8100 + 8100 = 16200 So C^2 = 16200 Take the square root of both sides C = 127.2792 Round to the nearest tenth, giving C = 127.3
Answer:
radius = 1
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 2)² + (y + 3)² = 1 ← is in standard form
with r² = 1 ( take the square root of both sides )
r = 
= 1
Answer;
x = 0.6 and x = -1.75
Step-by-step explanation:
80x2+92x−84=0
Use quadratic formula
x = (−b ±√(b2−4ac))/√2a
x = (-92 ± √(35344)) / 160
x = 95/160 and x = -280 / 160
x = 0.6 and x = -1.75
