Lina20 [59]

Answer:

\frac{1}{2}

Step-by-step explanation:

\frac{3}{4} × \frac{2}{3}

Cancel the 3 on the numerator/ denominator

Which sequence of transformations takes figure B to its image B'?
marin [14]

Answer:

D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin

Step-by-step explanation:

Well, the first obvious step is to reflect it across the y-axis. Now, for the next step, since we do not have a <em>90°-clockwise rotation </em>option, we have to go with something similar to that, which would be a <em>270°-counterclockwise</em> <em>rotation</em><em>.</em><em> </em>If you think about it, since 3 × 90 is 270, and rotating this figure 90° clockwise [one rotation] would go from Quadrant III to Quadrant II, going the other way around [270°counterclockwise (three rotations)] will also go from Quadrant III to Quadrant II [to Quadrant IIII to Quadrant I to Quadrant II].

I am delighted to assist you anytime my friend.

Answer:

  H(t) = 15 -6sin(2.5π(t -0.5))

Step-by-step explanation:

For midline M, amplitude A, period T and time t0 at which the function is decreasing from the midline, the function can be written as ...

  H(t) = M -Asin(2π/T(t -t0))

Using the given values of M=15, A=6, T=0.8 and t0 = 0.5, the equation is ...

  H(t) = 15 -6sin(2.5π(t -0.5))
