A laser beam is transmitted with a "width" of .0008 degrees and

pickupchik [31]

Answer:

Object will be at a distance of 358098.6 km from the source

Step-by-step explanation:

We have given angle = 0.0008 degree $=\frac{0.0008\times \pi }{180}=4.444\times 10^{-6}\pi$

Radius is given = 2.50 km

Linear size of the object will be equal to diameter

So linear size = 2.5×2 = 5 km

We know that linear size $=distance \times \Theta$

So $5=d\times 4.444\times 10^{-6}\pi$

d = 358098.6 km

Solve the proportion 5/25= x/20

vovikov84 [41]

5/25 = x/20

To solve a proportion cross multiply:

(5 * 20) = (25 * x)

Simplify:

100 = 25x

Divide both sides by 25:

x = 100/25

x = 4

Please help me I’m so lost !!!!

Tasya [4]

Answer:

$4095$

Step-by-step explanation:

$\sum _{n=1}^63\left(4^{n-1}\right)\:$

$\sum _{n=1}^63\cdot \:4^{n-1}$

Compute general progression:

$\frac{3\cdot \:4^{\left(n+1\right)-1}}{3\cdot \:4^{n-1}}=4$

$r=4\\$

$a_1=3\cdot \:4^{1-1}$

$a_1=3$

nth term is computed by:

$r=4,\:a_n=3\cdot \:4^{n-1}$

plug in the values $n=6,\:\spacea_1=3,\:\spacer=4$ :

$=3\cdot \frac{1-4^6}{1-4}$

$=4095$
