Aphysical education class is running a mile. the teacher has set a goal of 12 minutes to complete the mile.
students receive a score to show how close they are to the target of 12 minutes. for example, if students run the
mile in 8 minutes, their scores will be 4. complete the statements about the students' scores
anja ran the mile in her score is -2.
issac ran the mile in 13 minutes. his score is
simon ran the mile in 12 minutes. his score is

addition

step-by-step explanation:

35-60 students are taking math.

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
