tresset_1 [31]3 years ago

7 0

Answer:

Step-by-step explanation:

First, multiply straight across and put everything together:

$\frac{3a}{b}\cdot \frac{b^2}{12c}=\frac{3ab^2}{12cb}$

Notice we can simplify by cancelling a b and reducing 3/12:

$=\frac{ab}{4c}$

This cannot be simplified further.

Find the amplitude and the equation of the midline of the periodic function.

Masja [62]

Answer:

Option B. Amplitude =3 midline is y =2.

Step-by-step explanation:

In the graph attached we have to find the amplitude and midline of the periodic function.

Amplitude of the periodic function = (Distance between two extreme points on y asxis)/2

= (5-(-1))/2 = (5+1)/2 =6/2 =3.

Since amplitude of this function is 3 and by definition amplitude of any periodic function is the distance between the midline and the extreme point of wave on one side.

Therefore midline of the wave function is y=2 from which measurement of the amplitude is 3.

10. Rotate the figure shown 180° clockwise. Record the coordinates of the 3 points image.

inna [77]

Answer:

$J' = (6,7)$

$K' = (6,2)$

$L'=(3,7)$

Step-by-step explanation:

From the attachment, we have:

$J = (-6,-7)$

$K = (-6,-2)$

$L = (-3,-7)$

Rotation: 180 degrees clockwise

Required

Find J', K' and L'

When a point (x, y)is rotated 180 degree clockwise, the resulting point is: (-x, -y)

So, we have:

$J' = (6,7)$

$K' = (6,2)$

$L'=(3,7)$

3. Answer: y = 4

Step-by-step explanation:

Need to find the slope (m):

$\dfrac{y_2-y_1}{x_2-x_1}$

$\dfrac{4 - 4}{-3-1}$

= $\dfrac{0}{-4}$

= 0

Now input ONE of the points (1, 4) and the slope (m = 0) into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - 4 = 0(x - 1)

y - 4 = 0

y = 4

4. Answer: $\bold{y = \dfrac{2}{3}x + 3}$

Step-by-step explanation:

$y - y_1 = m(x - x_1)$

$y - 1 = \dfrac{2}{3}(x - (-3))$

$y - 1 = \dfrac{2}{3}(x + 3)$

$y - 1 = \dfrac{2}{3}x + 2$

$y = \dfrac{2}{3}x + 3$
