Determine the inverse function
Make F the subject of formula:
Multiply through by 9
Add 32 to both sides
Divide through by 5
I Believe It’s 2x^5-5x^4-6x^3
C because you multiply the big number with the lower number then you add the number on top. 3 times 3 equals 9 plus 2 = 11. you keep the bottom number under your new number
thanks for your help I really think that it's three
Answer:
QH = 227.8 km ≅ 228 km
Step-by-step explanation:
∵ The bearing from H to P is 084°
∵ The bearing from P to Q is 210°
∵ The distance from H to P = 340 km
∵ The distance from P to Q = 160 km
∴ The angle between 340 and 160 = 360 - 210 - (180 - 84) = 54°
( 180 - 84) ⇒ interior supplementary
By using cos Rule:
(QH)² = (PH)² + (PQ)² - 2(PH)(PQ)cos∠HPQ
(QH)² = 340² + 160² - 2(340)(160)cos(54) = 51904.965
∴ QH = 227.8 km ≅ 228 km
