All rhombi are parallelogram

1 answer:

4 0

Yes, that is true. Parallelograms are quadrilaterals where both of the pairs of opposite sides are parallel to each other. (they will never intersect if they go on forever) Rhombi are parallelograms where all of the sides are equal length.

Determine the exact values of all three trigonometric functions of the angle 4.25pi

Margarita [4]

Answer:

Sin (4.25π)= 0.7071

Cos(4.25π)= 0.7071

Tan(4.25π)= 1

Step-by-step explanation:

$\pi=180º (half circumference)\\ 2\pi= 360º (complete circumference)\\ 4\pi= 720º (2 complete cincumference\\ 4.25\pi= 720º + 45º (2 complete circumference + 45º)$

Sin, Cos and Tan of 45º angle is the same with 1,2 or more circumferences.

So the result is the same for 45º angle.

So:

$Sin (45º) = \frac{\sqrt{2} }{2}\\Cos (45º) = \frac{\sqrt{2} }{2}\\ Tan(45º) = 1$

Answer:

k = 24

y = 72

Step-by-step explanation:

Direct variation Formula:

y=kx

72=3k

k = 24

y = kx

y = 24(3)

y = 72

Solve for q.<br> -0.07(q - -6) + -4.67 = -5.3<br><br> Y’all please help :)

yaroslaw [1]

-0.07(q- -6) + -4.67 = -5.3

Distribute the -0.07

-0.07q + -0.42 + -4.67 = -5.3

Combine like terms

-0.42 + -4.67= -5.09

-0.07 - 5.09= -5.3

Add 5.09 to both sides

-0.07q= -0.21

Divide both sides by -0.07

Q= 3
