A blimp can be seen flying at an altitude of 5500 feet above a motor speedway during a race. The slanted distance directly to th

Vladimir [108]

Answer:

The expression of h as function of x is h = $\sqrt{(d + 5500) (d - 5500)}$

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 = $\frac{AC}{BC}$ = $\frac{h}{d}$

And sin Ф = $\frac{AB}{BC}$ = $\frac{5500}{d}$

∵, cos²Ф = 1 - sin²Ф

So, $(\frac{h}{d})^{2}$ = $1 - (\frac{5500}{d})^{2}$

Or, $(\frac{h}{d})^{2}$ = $(\frac{d^{2}- 5500^{2}}{d^{2}})$

Or, h² = d² - 5500²

∴ h = $\sqrt{d^{2}- 5500^{2}}$

Or, h = $\sqrt{(d + 5500) (d - 5500)}$

Hence The expression of h as function of x is h = $\sqrt{(d + 5500) (d - 5500)}$ Answer

How many whole minutes does it take 10000 viruses to grow to 1 million if their population doubles every 15 minutes?

nikitadnepr [17]

Let's solve how many whole minutes does it take 10 000 viruses to grow to 1 million if their population doubles every 15 minutes.
=> 10 000 x n = 1 000 000
=> 1 000 000 / 10 000 = 100 times
=> 100 times * 15 minutes = 1500 minutes to make 1 million viruses

Find the length of LA Triangle proportionality

slavikrds [6]

Answer:

Step-by-step explanation:

4 x __ = 12

the blank would be 3, once you did it on one side you have to do it on the other side too

5 x 3 = 15

Another way you can do it is by...

$\frac{4}{12}$ = $\frac{5}{x}$

solve for x (cross multiply)

The circumference of a circle is 18.84 miles. What is the circle's radius? C=18.84

Mama L [17]

We can find the radius by using the formula: C = 2(pi)(r)
We'll use 3.14 for pi.

And solve for r.

18.84 = 2(3.14)r ; Start
18.84 = 6.28r ; Multiply 3.14 by 2
3 = r ; Divide both sides by the coefficient of r. Which is 6.28

So, the radius is 3 miles.
