( i will give brainlist ) What is the equation of the following graph?
Ne4ueva [31]

Answer:

y= ⅓x +2

Step-by-step explanation:

Since the graph is a linear graph, let's use the slope-intercept form to find its equation.

<u>Slope-intercept </u><u>form</u>

y= mx +c, where m is the slope and c is the y-intercept.

The y-intercept is the point at which the graph cuts through the y-axis. In this case, the y-intercept is 2.

Thus, y= mx +2.

Let's find the slope of the graph.

First, identify 2 pairs of coordinates from the graph:

(0, 2) and (3, 3)

Next, substitute these coordinates into the slope formula below:

\boxed{ \text{slope} = \frac{y _{1} - y_2 }{x_1 - x_2} }

slope

=  \frac{3 - 2}{3 - 0}

=  \frac{1}{3}

Thus, the equation of the graph is y= ⅓x +2.

Answer:

5.3

Step-by-step explanation:

Use Pyth Theorem

a^2 + b^2 = c^2

6^2 + b^2 = 8^2

36 + b^2 = 64

b^2 = 28

Sq root of 28 = 5.3

If an object is dropped from a height of 55 feet, the function d = -16^2 + 55 gives the height of the object after t seconds. Gr
motikmotik

Answer:

Approximately  1.9 seconds   (correct to nearest tenth)

Step-by-step explanation:

Looks like the function is  d = -16t^2 + 55    ( you left out the t)

The answer is the value of t when d = 0 so we have the equation:-

0 =  -16t^2 + 55

16t^2 = 55

t^2 = 55/16

t = sqrt (55/16)

= 1.85 seconds
