Point slope equations

Mathematics
1 answer:
Sholpan [36]3 years ago
4 0

Answer:

The point slope equation is: y - y1 = m (x - x1)

m = slope

Step-by-step explanation:

To use this equation, you need to know:

-<u> </u><u>one point on the line</u>

-<u> the slope of the line</u>

<u>First</u>:

(x1,y1) = a known point on the line

m = the slope

(x,y) = any other point on the line

<u>Now</u>:

we plug the numbers into the equation to get y - y1 = m (x - x1)

<u>Then</u>:

you solve the equation

A ball is kicked upward with an initial velocity of 56 feet per second. The ball's height h (in feet) can be expressed as a func
siniylev [52]

Answer:

1.75

Step-by-step explanation:

h(t) = -16t² + 56t

h'(t) = -32t + 56

To find time at max height equate h' to 0

0 = -32t + 56

t = 56/32 = 1.75 s

It takes 1.75 s to reach max highest point

nexus9112 [7]

Answer:

The correct answer is: Option D: 26 vehicles

Step-by-step explanation:

Median is the middle value of a sorted data set.

The formula for median depends on the number of values in the dataset.

First of all we have to arrange the given data in order

So,

14 19 23 24 24 24 24 26 26 26 26 26 27 27 28 29 30 30 30 34

Counting the values in the dataset

n = 20

As the number of values is even, the formula for median will be

M = \frac{1}{2}(\frac{n}{2}th\ value+(\frac{n}{2}+1)th\ value)

Putting the values

M = \frac{1}{2}(\frac{20}{2}th\ value+(\frac{20}{2}+1)th\ value)\\M=\frac{1}{2}(10th\ value +[10+1]th\ value]\\M= \frac{1}{2}(10th\ value + 11th\ value)

The 10th value in dataset is 26 and 11th is also 26 so

M = \frac{1}{2}(26+26)\\M = \frac{1}{2}(52)\\M = 26

Hence,

The correct answer is: Option D: 26 vehicles
