Answer:

The measure of angle R is $28.07\°$

Step-by-step explanation:

we know that

In the right triangle PRQ

The cosine of angle R is equal to the adjacent side angle R divided by the hypotenuse

so

$cos(R)=\frac{QR}{PR}$

substitute the values

$cos(R)=\frac{15}{17}$

$R=arccos(\frac{15}{17})=28.07\°$

Answer:

Step-by-step explanation:

Given that there are two vectors U = (-8,0,1)

V = (1,3,-3)

To find projection of u on V and also projection of V on U

First let us find the dot product U and V

U.V = $-8(1)+0(3)+1(-3)\\= -11$

Projection of U on V = $\frac{U.V}{|V|} \\=\frac{-11}{\sqrt{1+9+9} } \\=\frac{-11}{\sqrt{19} }$

Similarly projection of V on U

= $\frac{U.V}{|U|} \\=\frac{-11}{\sqrt{64+0+1} } \\=\frac{-11}{\sqrt{65} }$

Answer:

<h2>C. 3 gal. 3 qt. 1 pt.</h2>

Step-by-step explanation:

1 gallon = 4 quarts

5 gallons 2 quarts 1 pint = 4 gallons 6 quarts 1 pint

(5 gallons 2 quarts 1 pint) - (1 gallon 3 quarts)

= (4 gallons 6 quarts 1 pint) - (1 gallon 3 quarts)

= 3 gallons 3 quarts 1 pint
