Answer:
a. Negative discriminant: above
b. Positive discriminant: below
c. Discriminant is zero: on
Step-by-step explanation:
If the discriminant is negative, then there are no real zeros. We have an upward-facing parabola, then the vertex is located above the x-axis
If the discriminant is positive, then there are two different real zeros. We have an upward-facing parabola, then the vertex is located below the x-axis
If the discriminant is zero, then there is one zero. We have an upward-facing parabola, then the vertex is located on the x-axis
Answer:
165.628° (The 8 has a line over it signalizing that it repeats forever, but I didn't know how to put it in.)
Step-by-step explanation:
Since 165 is whole number, it is a full degree. Since each minute is equal to 1/60 degrees, you need to multiply 37 by 1/60. Since each second is equal to 1/3600 degrees, multiply it 1/3600 by 44. Add them all together.
165 + 37 x 1/60 + 44 x 1/3600
simplify: 74533/450
Convert the fraction into a decimal by dividing the numerator by the denominator and you get 165.628° (with a repeating 8).
0.4 grams or 0.40 grams however you like writing decimals, but either way they are both the same.
Answer:
1/3
Step-by-step explanation:
In order for the disc to be entirely contained in a rectangular tile, its center must be at least 1 unit from the nearest edge. Which means there's a 2 by 4 region that the center can lie in.
So the probability is (2×4) / (4×6) = 8/24 = 1/3.
If he swan the length and the width of the pool it would be 21 x28 = 588 sq ft.
by swimming the length and the diagonal of the pool (25 ft) found that by using the pythagorean therom so now you are multiplying 21 x 25 = 525
588-525= 63 ft he is saving
