Answer:
ax2 + bx + c = 0.
Step-by-step explanation:
The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero.
Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
Answer:
it means the answer of a division problem
Step-by-step explanation:
Given:
long stick: 3 4/5 feet
short stick: 3 1/2 feet
convert mix fractions into improper fractions:
3 4/5 = (3*5)+4/5 = 19/5 long stick
3 1/2 = (3*2)+1/2 = 7/2 short stick
19/5 - 7/2 ⇒ (19/5 * 2/2) - (7/2 * 5/5) = 38/10 - 35/10 = (38 - 35)/10 = 3/10
3/10 feet should be cut from the longer stick so that the two walking sticks will be the same length.
3 4/5 ft = 45.6 inches long stick
3 1/2 ft = 42 inches short stick
3/10 ft = 3.6 inches to be cut from long stick
45.6 inches - 3.6 inches = 42 inches
