a line passes through (8,-4) and has a slope 2/3. what is an equation in point slope form of the line? An equation of the line i
evablogger [386]

from the question

x₁ = x-coordinate = 8

y₁ = y-coordinate = - 4

m = slope of line = 2/3

slope form of the line is given as

(y - y₁ ) = m (x - x₁)

inserting the values

(y - (- 4) ) = (2/3) (x - 8)

(3) (y + 4) = (2) (x - 8)

multiplying each term inside the bracket by 3  and 2 respective on left and right side

3y + 12 = 2 x - 16

2 x - 3 y - 16 - 12 = 0

2 x - 3 y - 28 = 0

A ball is thrown vertically upward with a speed of 19.0 m/s. (a) How high does it rise? m (b) How long does it take to reach its
Arte-miy333 [17]

Answer with Explanation:

We are given that

Initial speed=u=19 m/s

a.g=9.8m/s^2

Final velocity of ball=v=0

v=u-gt

g is negative because the ball is going against to gravity.

0=19-9.8t

9.8t=19

t=\frac{19}{9.8}=1.94 s

s=ut-\frac{1}{2}gt^2

Using the formula

s=19(1.94)-\frac{1}{2}(9.8)(1.94)^2

s=18.4 m

a.The ball rise upto height 18.4 m

b.It take 1.94 s to reach its highest point.

c.Initial velocity=0,s=18.4 m

s=ut+\frac{1}{2}gt^2

18.4=0(t)+\frac{1}{2}(9.8)t^2

18.4=4.9t^2

t^2=\frac{18.4}{4.9}

t=\sqrt{\frac{18.4}{4.9}}

t=1.94 s

v=u+gt

Using the formula

v=0+9.8(1.94)=19 m/s
