Answer: 4. 78,020,008 4. Seventy-eight million, twenty thousand, eight
5. 20,011,012 5. 20,000,000 + 11,000 + 12
6. 50,000 7. 900 8. 70,000,000 9. 30,000,000
Step-by-step explanation:
3/2 since perpendicular lines have opposite reciprocal slopes
Quadrant is III so, sign would be negative for Sec.
Now, we know, csc = H / P
So, H = 4, P = 3
Calculate for B,
B² = H² - P²
B² = 4² - 3²
B² = 16 - 9
B = √7
We know, sec Ф = H / B = 4 / √7
We can write it as: -4√7 / 7 [ -ve sign for 3rd quadrant ]
In short, Your Answer would be Option B
Hope this helps!
