Which equation can be used to find A, the area of the parallelogram shown?
aniked [119]
<h3>Answer: A = 6 x 7  </h3>

Explanation:

The area of a parallelogram is equal to base times height.

The base and height are always perpendicular to one another. Usually the base is horizontal along the ground (if not then you'd need to rotate your paper until it is, but that step is optional).

The base is 6 meters and the height is 7 meters.

Therefore, area = base x height = 6 x 7

The side of 11 meters is not used at all. It's likely put in there as a distraction.

For the function y = -2 + 5 sin (pi/12(x-2)), what is the minimum value?
LekaFEV [45]

Answer:

The maximum value is 3.

Step-by-step explanation:

The given trigonometric function is

y=-2+5\sin(\frac{\pi}{12}(x-2))

The amplitude of this function is 5.

|A|=5

-5\le A\le5

The function is shifted vertically down by two units.

To find the maximum value, we add -2 to the upper boundary of A.

The maximum values is 5-2=3

the minute hand on a large clock has a radius of 16 inches. Find the distance the minute hand will travel in one hour.
alexira [117]
Hi.

C =<em> </em>2<em />π<em>r
</em>
<em>r = </em>16

2π(16) = 100.48 (π = 3.14)

The clock will travel 100.48 in in one hour.

(TUTORS WHERE R U?? KIDS NEED HELP LIKE ME!! ILL GIVE BRAINLYY)
KengaRu [80]

Answer:

11. 10x^2 - 13x - 3

12. 5x^2 + 18x + 5

Step-by-step explanation:

11. Product means multiplication, so you can multiply (5x + 1) and (2x - 3).

(5x + 1) * (2x - 3) - Using the FOIL (First+Outer+Inner+Last)

So: (5x*2x) + (5x*-3) + (1*2x) + (1*-3)\\10x^{2} -15x + 2x -3\\10x^{2} -13x -3

12. 3x^{2} + 8x - 1 + 2(x^{2} +5x + 3) (So, you distribute the 2 to x^2 + 5x + 30, then combine like terms).

3x^{2} + 8x - 1 + 2(x^{2} +5x + 3)\\3x^{2} + 8x - 1 + 2x^{2} +10x + 6\\(3x^{2} +2x^{2}) + (8x + 10x) + (-1+6)\\5x^{2} + 18x + 5

Hopefully, this helped you. Good luck & have a good day!
