Answer/Step-by-step explanation:
✔️Find k:
Reference angle = 60°
Hypotenuse = k
Opposite = 9
Therefore, using trigonometric ratio, we have:
Multiply both sides by k
Divide both sides by sin(60)
Rationalize
✔️Find f:
Reference angle = 60°
Opposite = 9
Adjacent = f
Therefore, using trigonometric ratio, we have:
Multiply both sides by f
Divide both sides by tan(60)
Rationalize
It would be -f (x^2 – 5) because being that it reflected across x-axis its turn into a negative and translated 5 units to the left thats a horizontal change so it is on the inside, H (IN) horizontal change goes inside the parentheses, V OUT vertical changes go outside the parentheses
Answer:
£100
Step-by-step explanation:
if the ratio is 7:3, the difference between them is 7-3 . = 4.
So,
4x = £40
Now, calculate x
x = £10
Now,
we are able to calculate:
7x (Bridget's share) = £70
3x (Caroline's share) = £30
Sum = £100
Hope this helps.
Good Luck
