Pls help asap make sure the answer is in decimal from ! will mark brainliest

w = - 16.06 or w = 2.06

Step-by-step explanation:

Given

w² + 14w - 33 = 0 ( add 33 to both sides )

w² + 14w = 33

To complete the square

add ( half the coefficient of the w- term )² to both sides

w² + 2(7)w + 49 = 33 + 49, that is

(w + 7)² = 82 ( take the square root of both sides )

w + 7 = ± ( subtract 7 from both sides )

w = - 7 ± , that is

w = - 7 - ≈ - 16.06 or w = - 7 + ≈ 2.06

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
