A blimp can be seen flying at an altitude of 5500 feet above a motor speedway during a race. The slanted distance directly to the pagoda at the startdashfinish line is d feet. Express the horizontal distance h as a function of d.

Answers

Answer:

The expression of h as function of x is   h = √((d + 5500) (d - 5500))

Step-by-step explanation:

Given as :

The distance of blimp  (AB) = 5500 feet

The slanted distance to the pagoda (BC) = d feet

The horizontal distance (AC) = h

Let the angle made between slanted distance and horizontal distance be Ф

So , cos Ф = (AC)/(BC) = (h)/(d)

And sin Ф =  (AB)/(BC) = (5500)/(d)

∵, cos²Ф = 1 - sin²Ф

So, ((h)/(d))^(2) = 1 - ((5500)/(d))^(2)

Or, ((h)/(d))^(2) = ((d^(2)- 5500^(2))/(d^(2)))

Or,                                     h² = d² - 5500²

∴                                        h = \sqrt{d^(2)- 5500^(2)}

Or,                                     h = √((d + 5500) (d - 5500))

Hence The expression of h as function of x is   h = √((d + 5500) (d - 5500))     Answer

Work out -4x-3+2x-6 can I have help please ?

Answers

Let's reorder the equation. -4x+2x-3-6. Now we can reduce like terms. -4x+2x= -2x and -3-6= -9. Put the two back together and it is simplified to -2x-9.
-4x-3+2x-6-4x+2x-6-3-2x-9I hope that is good!
