Answer:b=5

Step-by-step explanation:the formular for pythagoras theory is

C^2=a^2+b^2

13^2=12^2+b^2

169=144+b^2

Collect like terms

169-144=b^2

b^2=25

Take the the square root of both sides

b=square root of 25

b=5

Kristen is 64 inches tall, and she stands 12 feet away from a streetlight. If she casts an 82-inch-long shadow, how tall is the

o-na [289]

Answer:

176.39 inches or

14.70 feet

Step-by-step explanation:

Consider the right triangle made by Kristen, ground and shadow.

This triangle has one leg as 64 inches.

Next consider the right triangle formed by street light, ground upto shadow tip.

The two triangles have common angle of elevation and also another angle as 90 degrees.

Hence the two triangles would be similar

Also if A is the angle made by hypotenuse of both triangles with the ground we have

$tanx=\frac{64}{82}$

This value also equals by bigger triangle as

$tanx=\frac{h}{82+12(12)}=\frac{h}{226}$

From these two we get

h = height of street light = $\frac{226(64)}{82} =176.39$

The position function for the movement of a particle is given by s=(t^3+1)^2 where s is measure in feet and t is measured in sec

Ray Of Light [21]

Answer:

The position of particle at 1 second is 4 feet.

Step-by-step explanation:

We are given the following in the question:

$s(t)=(t^3+1)^2$

where s is a position function and measure in feet and t is measured in seconds.

We have to evaluate the position at 1 second.

Putting t = 1 in the position function, we get.

$s(1)=((1)^3+1)^2\\s(1) = 4$

Thus, the position of particle at 1 second is 4 feet.
