.
In the given figure, the values of adjacent side, opposite side and hypotenuse are not given.
Answer:
y -G = -1/3 ( x- F)
Step-by-step explanation:
The line on the plane has a slope
m = (y2-y1) /(x2-x1)
(0,-2) and (1,1)
= (1- -2)/( 1-0)
= (1+2)/(1-0)
= 3/1
Perpendicular lines have slopes that multiply to -1
m * 3 = -1
Divide by 3
m = -1/3
The perpendicular line has a slope of -1
The point slope equation is
y - y1 = m(x-x1)
y -G = -1/3 ( x- F)
If you use this equation then you say that the ground is h=0 and solve as a quadratic.
The quadratic formula is (-b±<span>√(b^2-4ac))/2a when an equation is in the form ax^2 + bx + c
So the equation you have been given would be -16t^2-15t-151 = 0
This equation has no real roots which leads me to believe it is incorrect.
This is probably where your difficulty is coming from, it's a mistake.
The equation is formed from S=ut+(1/2)at^2+(So) where (So) is the initial height and S is the height that you want to find.
In this case you want S = 0.
If the initial height is +151 and the initial velocity and acceleration are downwards (negative) and the initial velocity (u) is -15 and the initial acceleration is -32 then you get the equation S=-15t-16t^2+151
Solving this using the quadratic formula gives you t = 2.64 or t = -3.58
Obviously -3.58s can't be the answer so you're left with 2.64 seconds.
Hope this makes sense.

The first one is dependent. It depends on the hose to figure out how much water there is.
Answer:
if it took her 14 hours to make a 30-inch scarf, we can assume it will take her to double that time to make a 60-inch scarf. 28 hours is double of 14, if she only knits one hour every day it will take her 4 weeks, 28 days is equal to exactly 4 weeks 28/7=4 weeks
