Answer:
128/15 min or 8.5 min
Step-by-step explanation:
By using unitary method,
Time required to paint 5/8 of wall = 16 min.
Time required to paint 1/1 of wall = 16×8/5
Hence, Time required to paint 1/3 of wall = 16×8/5×1/3
Answer:
g(x) exceed f(x) by
when 
Step-by-step explanation:
step 1
Find the equation of function f(x)
we know that
The initial value is the y-intercept of the linear function (value of y when the value of x is equal to zero)
so

The rate of change is equal to the slope
so

therefore

step 2
Find the equation of function g(x)
Let

Find the slope

----> point A
therefore

step 3
Find the value of f(x) and g(x) for 


Find the difference

He soled 21 and 1/2 of almonds at the fair because 25 is = to 24 and 2/2 so that - 3 and 1/2 is = to 21 and 1/2
The height of the project becomes zero when it hits the ground which is also the total time at which the projectile stays in the air. Equating the function to zero:
-10(x)(x - 4) = 0
The roots of this quadratic equation are:
x = 0, and x=4
Therefore, the projectile stays in the air for
4 seconds
