Ablimp 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.

The expression of h as function of x is   h =

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 = =

And sin Ф =   =

∵, cos²Ф = 1 - sin²Ф

So, =

Or, =

Or,                                     h² = d² - 5500²

∴                                        h =

Or,                                     h =

Hence The expression of h as function of x is   h =     Answer

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
