Answer:9.51
Step-by-step explanation:You add them for the total
1 + tan ² Ф=sec²Ф
1+(12/5)²=sec²Ф
169/25=sec² Ф
sec Ф=⁺₋√(169/25)=⁺₋13/5
sec Ф=1/cos Ф ⇒cosФ=1/sec Ф
cos Ф>0 ⇔ sec Ф>0 ⇔ sec Ф=+ 13/5
cos Ф=1/secФ
cos Ф=1 / 13/5=5/13
we can calculate the sin Ф, with this method.
sin²Ф + cos²Ф=1 ⇒ sin Ф=⁺₋√(1-cos² Ф)
sin Ф=⁺₋√[1-(5/13)²]=⁺₋12/13
like cos Ф>0 and tan Ф>0 ⇒ sin Ф>0 ⇒sin Ф=12/13
answer: d.12/13
other method
tan Ф=sin Ф / cos Ф
12/5=sin Ф / 5/13
sin Ф=(12/5)*(5/13)=12/13
answer: d.12/13
Answer:
- C. The surface area of the pyramid is multiplied by 100
Step-by-step explanation:
The area is the function of the two dimensions.
If each dimension has changed by 10 times, the the area will change by:
Correct choice is C
1) 4(8j + 9)
2) 24j + 36 + 8j

$1142.25
Step-by-step explanation:
Gross pay per week = $1500
Social security deducted = 6.2% = $93
Medicare deducted = 1.45% = $21.75
Deductions for combined taxes = 16.2% = $243
Hence total deductions made from the gross salary
= 93+21.75+ 243
= $357.75
Hence, Net pay
= 1500 - 357.75
= $1142.25
