8 0

Answer:

13/6 or Decimal: 2.166667

Step-by-step explanation:

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

ok so first i subtract the 7-20 because they both are the y-coordinate

then a subtract the other points which is -14-20

then I divide the two numbers

An arrow is shot vertically upward from a platform 19ft high at a rate of 163ft/sec. When will the arrow hit the ground? Use the

Triss [41]

Answer: 10.3 s

Step-by-step explanation:

Given

The height of the arrow is given by $h=-16t^2+v_ot+h_o$

At $t=0, h=19\ ft$ and $v_o=163\ ft/s$

When arrow hits ground, h becomes 0 i.e.

$\Rightarrow 0=-16t^2+163t+19\\\Rightarrow 16t^2-163t-19=0\\\\\Rightarrow t=\dfrac{163\pm \sqrt{(-163)^2+4(16)(19)}}{2(16)}\\\\\Rightarrow t=-0.115,10.30\ s$

Neglecting the negative value of t

So, the arrow hits the ground after 10.30 s

George is twice the age of Mike minus 5. The sum of George and Mike's ages is 31. How old is George and write an equation to rep

Temka [501]

Answer:

George is 19

Step-by-step explanation:

George is g and Mike is m

g = 2m - 5
g + m = 31

Substitute g in the second equation

2m - 5 + m = 31
3m - 5 = 31
3m = 36
m = 12

Finding g

g = 2*12 - 5 = 24 - 5 = 19
