3241004551 [841]

Answer:

729 , 3- digit codes are possible

Step-by-step explanation:

To use an automated teller machine at a certain bank, you must enter a 3-digit code, using the digits 1 dash 9.

We need a 3 digit code using digits 1 to 9

so total of 9 digits are used

also repetition of digits are permitted

In a 3 digit code, first digit can be any number from 0 to 9

so 9 possible numbers for first digit.

since repetition is allowed so second and third digit also have any number between 0 to 9

3 digit code

------ , ------- , --------

9 possibilities for each place

---9--- , ----9--- , ----9----

9 *9 *9 = 729

so 729 , 3- digit codes are possible

The flagpole in front of CB East casts a shadow 40 feet long when the measurement of the angle of elevation to the sun is 31˚. H

IRINA_888 [86]

Answer: The length of flagpole is 24 feet.

Step-by-step explanation:

Since we have given that

Length of shadow =40 feet

Angle of elevation to the sun = $31\textdegree$

In ΔABC,

We can apply "trigonometric rules ",

$\tan\theta=\frac{AB}{BC}\\\\\tan31\textdegree=\frac{AB}{40}\\\\0.6\times 40=AB\\\\24\ feet=AB$

Hence, the length of flagpole is 24 feet.
