A license plate is to consist of 5 digits followed by 5 uppercase letters. Determine the number of different license plates poss

EastWind [94]

Answer:

$5.3044992\times 10^{10}$

Step-by-step explanation:

We are given that a license plate consist of 5 digits and 5 uppercase letters

Digits used=0,1,2,..9

Total number of letters=26

Repetition is not allowed

Total number of odd digits=(1,3,5,7,9)=5

The first place filled by 5

Second place filled by 4

Third place filled by 8

Fourth place filled by 7

Fifth place filled by 6

Sixth place filled by 26

Seventh place filled by 25

Eighth place filled by 24

Ninth place filled by 23

Tenth place filled by 22

Total number of possible different license plates = $5\times 4\times 8\times 7\times 6\times 26\times 25\times 24\times 23\times 22$ = $5.3044992\times 10^{10}$

While surveying Overlook Cave, Mike measures the angle of elevation from his line of sight to the top of a rock formation as 22°

Kaylis [27]

Answer:

The rock formation is approximately 7 feet tall.

Step-by-step explanation:

We can visualize this situation as a triangle and know that the bottom side is 10 and the angle of elevation (the angle created by Mike and the ground, looking to the top of a rock). With this information, we can use tangent to solve.

x = the height of the rock formation

tan(22°) = x/10

10 tan(22°) = x

x = ~4.04 feet

We also have to add the 3 feet to it because it is being measured 3 feet above the floor.

x + 3 = 7.04 feet
