Answer:
She has to cut another piece = 7.75 inches
Total length = 4x + 7.75
This is what y represent, so
y = 4x + 7.75
The graph of the equation is continuous
Answer:
268.08
rounded number- 268
find the number in the whole number place, 8, and look one place to the right for the rounding digit on the right side of the decimal point, 0. round up if this number is greater than or equal to 5, and round down if it is less than 5.
formula for sphere volume- 4/3 (pie- 3.14) r^2
Answer:
x^2 + x + 2 = 0.
Step-by-step explanation:
The discriminant b^2 - 4ac is < 0 for complex roots.
So we can choose appropriate values for a, b and c.
Let b = 1, a = 1 and c = 2 so b^2 - 4ac = 1 - 4*1*2 = -7.
So our equation is:
x^2 + x + 2 = 0.
