What is the sope of (5,9) and (4,11)

Vikentia [17]

Answer:

The answer to your question is slope = -2

Step-by-step explanation:

Data

A = (5, 9)

B = (4, 11)

slope = m = ?

Slope means the steepness of a line.

Process

1.- Write the formula to calculate the slope

m = (y2 - y1) / (x2 - x1)

x1 = 5 y1 = 9 x2 = 4 y2 = 11

2.- Substitution

m = (11 - 9) / (4 - 5)

3.- Simplification

m = 2/-1

4.- Result

m = -2

An object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seco

bulgar [2K]

Answer:

$y=2\text{cos}((\frac{2\pi}{3})t)$

Step-by-step explanation:

We have been given that an object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seconds. We are asked to find the cosine function that can be used to model the height of the object.

We know that standard form of cosine function is $y = A\cdot \text{cos}(Bt-C)+D$ , where,

|A| = Amplitude,

Period = $\frac{2\pi}{|B|}$ ,

C = Phase shift,

D = Vertical shift.

Since distance between maximum and minimum is 4, therefore, amplitude will be half of it, that is, $A = 2$ .

Since objects gets back to its maximum value in every 3 seconds, therefore, period of the function is 3 seconds. We know that period is given by $\frac{2\pi}{|B|}$ , therefore, we can write $\frac{2\pi}{|B|}=3$ , therefore, $B = \frac{2\pi}{3}$ .
