In standard form, the equation is (x-2)^2+(y+9)^2=9, where we have plugged (h,k,r)=(2,-9,3) into the standard-form equation (x-h)^2+(y-k)^2=r^2. The center of this general form has coordinates (h,k), and the radius is r.

Figure ABCD is a parallelogram. If point C lies on the line y= -1, what is the x-value or point C?
MrRa [10]

Answer:

The correct answer is option D.  4

Step-by-step explanation:

Points to remember

Opposite sides of the parallelogram are equal.

From the figure we can see that,AB and CD are opposite sides.

Therefore AB = CD

<u>To find the length of AB</u>

From the figure we get, AB = 4 units

Therefore CD = 4 units

<u>To find the x coordinate of point C</u>

y coordinate is -1

x coordinate is 4 units from point D

x coordinate of D is 0, therefore x coordinate of C = 0 + 4 = 4

The correct answer is option D. 4

Explain why the expression 7•3x is not equal to the expression 21x
rusak2 [61]
The expression 7•3x is not equal to the expression 21x. You might think that the two expressions are the same since 7x3 is 21 but the first expression is a dot product. This kind of expression includes the magnitude and direction of the vector in an expression, for example, <span>7•3x. The second expression, 21x, expresses only the magnitude and does not include the direction.</span>

Answer:

vol. of triangular prism = lbh/2

vol. of rectangular prism = 18 of vol. of triangular prism

18x = 18 + 14x

4x = 18

x=4.5 ft

so vol. of rectangular prism = 6 × 4 . 5 × 3 = 81 ftcube
