For this case we have the following vector:
 v = (- 8, 2)
 Using product point we have:
 v.v = (-8, 2). (- 8, 2)
 v ^ 2 = (-8) * (- 8) + (2) * (2)
 v ^ 2 = 64 + 4
 v ^ 2 = 68
 v = root (68)
 v = root (4 * 17)
 v = 2 * root (17)
 Answer:
 
v = 2 * root (17)

Tyrone makes a scale drawing of his backyard. The scale from the backyard to the drawing is 2 ft to 1 in. The width of the patio
Sphinxa [80]

Answer:

The width of Tyrone's actual patio is 16 feet

Step-by-step explanation:

\frac{2ft}{1in} =  \frac{x}{8}   If we look at what we know, we see that the scale tells us that 1 inch is proportional to 2 ft.  What do we need to multiple 1 inch by to get 8 inches?  8.  So, we multiply 2 feet by 8 to get the actual size of the patio which is 16 feet.

Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pyth
ehidna [41]

Answer:

x = 4√2

Step-by-step explanation:

<u><em>Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pythagorean theorem</em></u>

To solve, we will follow the steps below:

using Pythagoras theorem

opposite² +  adjacent² = hypotenuse²

14² + y² = 18²

196 + y² = 324

subtract 196 from both-side of the equation

196 -196 + y² = 324-196

y² =128

Take the square root of both-side

√y² = √128

y =√128

y = √64×2

y =√64×√2

y = 8√2

x = half of y

x = y/2

x = 8√2  ÷  2

x = 4√2
