1. Each of the six cards shows a shape.

erik [133]

Answer:

a). Cards (1) and (4)

b). Cards (3) and (5)

Step-by-step explanation:

(a). From the cards attached,

If card (1) is rotated by an angle of 180° counterclockwise, we get the image given in card (4).

Therefore, card (4) will be the image of card (1) after a rotation.

(b). If we reflect card (3) across a horizontal line (or x- axis) image card (4) is obtained.

Therefore, card (3) and card (5) is the pair of cards.

For what values of theta (0 less than or equal to theta less than or equal to 2pi) do maximum r values occur on the graph the po

9966 [12]

Answer:

Step-by-step explanation:

To find the values of the angle which makes maximum r you use the derivative of r

$\frac{dr}{d\theta}=\frac{1}{3}sin(3\theta)$

If you equals this derivative to zero you obtain the value of the angle:

$\frac{dr}{d\theta}=0\\\\cos3\theta=0\\\\3\theta=\frac{\pi}{2}\\\\\theta=\frac{\pi}{6}$

However, the values of 5π/6 and 9π/6 are also available, because makes the sinusoidal function equal to 1.

hence, the answer is:

$\theta_1=\frac{\pi}{6} \\\\\theta_2=\frac{5\pi}{6}\\\\\theta_3=\frac{9\pi}{6}=\frac{3\pi}{2}$

On a drawing, the scale is 1 centimeter to 30 centimeters. Which of the following is not correct? actual length = 150 cm; drawin

Brrunno [24]

Answer:

drawing length = 7 cm; actual length = 200 cm

Step-by-step explanation:

The ratio is 1 cm in the drawing is 30 cm in actuality.

If the drawing is 5 cm, multiply by 5

5*1 to get the 5 cm drawing and 5*30 to 150 cm in actual length

5cm drawing = 150 cm actual

11cm drawing multiply by 11

11*1= 11 and 11*30 = 330 cm

11 cm drawing = 330 cm actual

7cm drawing multiply by 7

7*1= 7 and 7*30 = 210 cm

7 cm drawing = 210 cm actual

8cm drawing multiply by 8

The one that is not correct: drawing length = 7 cm; actual length = 200 cm

8*1= 8 and 8*30 = 240 cm

8 cm drawing = 240 cm actual
