A.) according to the graph, Austin appears to be burning 10 calories per minute. If you look at a perfect point on the graph, which I chose (50,5) and you do x over y or calories per minute, you get a unit rate of 10 calories per minute.

b.) Since you have already found the unit rate in question a, your slope would be 10.

Find the work done in moving an object along a vector r=3i+2j-5k if the applied force is F=2i-j-k

Alex73 [517]

The work is equivalent to the dot product of the two vectors.

$W=\mathbf F\cdot\mathbf r=\langle2,-1,-1\rangle\cdot\langle3,2,-5\rangle=6-2+5=9$

First, use the "completing the square" process to write this equation in the form (x + D)² = E. x² - 8 x + 12 = 0 is equivalent

Leni [432]

Answer:

D = -4

E = 2

Step-by-step explanation:

The procedure for completing the square method is given as:

x2 + bx + c = 0

x2 + bx = -c

x2 + bx + (b/2)2 = -c + (b/2)2

Aolving the LHS simultaneously,

(x + b)2 = -c + (b/2)2

Find the square root of both sides,

(x + b) = sqrt(-c + (b/2)2)

So for the equation, x2 - 8x + 12

x2 - 8x = -12

x2 - 8x + 16 = -12 + 16

(x - 4)2 = 4

So square root both sides,

(x - 4) = 2

Comparing this to the equation given,

(x - D) = E;

D = -4

E = 2

Find the hypotenuse for the following

masya89 [10]

Answer:

6.403 units

or $\sqrt{41}$

Step-by-step explanation:

We want the hypotenuse.

The hypotenuse is from the point (-3, -1) to point (2, 3)

D( (-3, -1), (2, 3)) = root ( (2 - (-3))^2 + (3 - -1)^2 ) =

D( (-3, -1), (2, 3)) = root ( 5^2 + 4^2) = root( 25 + 16)

D( (-3, -1), (2, 3)) = root ( 41)

D( (-3, -1), (2, 3)) = 6.403 units
