Consider the system of equations 2x1 + 1x2 + 5x3 = -1 1x1 + 0x2 + 6x3 = 2 -6x1 + 2x2 + 4x3 = 3 convert this system of equations into a matrix equation of the form cx = d. solve it by hand, and record your solution in your document. enter the matrix c and the column vector d into matlab, and use the command

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

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is

-8,5

step-by-step explanation:

the height of the building is 60.08 feet
