Step-by-step explanation:
Consider a function
f
(
x
)
which is twice differentiable. The graph of such a function will be concave upwards in the intervals where the second derivative is positive and the graph will be concave downwards in the intervals where the second derivative is negative. To find these intervals we need to find the inflection points i.e. the x-values where the second derivative is 0.
0.45×300= 135 2,335 - 135=2,200 2,200÷55= 40

This is how This is how much This is how many
much they paid was left in the days they paid for food
for the miles reimbursement and lodging
traveled
Part A: X= (2,335- ( 0.45 ×300) ) ÷55
Part B: I dont know how to do algebraic property of equality.
Part C: They spent 40 days or 1 month , one week and 3 days
we are given
we can use factoring formula
we can compare
and we get
now, we can solve for m and n
and we get
now, we can use formula
and we get
now, we can set it equal to 0
so, we will get
.............Answer
Two.
b1 = - 4 + sqrt(19), b2 = - 4 - sqrt(19)
The statement that matches the vector operation shown on the coordinate grid is v + w = u.
<h3>How to add two vectors graphically?</h3>
In order to add two vectors a and b graphically by using the tail and tip method, we must draw the tail of b at the tip of vector a.
Then we must draw a line that goes from the tail of vector a to the tip of vector b.
This line represents the sum of a + b.
In the given problem, we notice that the tail of the vector w is on the tip of the vector v.
The line that joins the tail of vector v with the tip of vector w is vector u.
Therefore we can say that v + w = u
The statement that matches the vector operation shown on the coordinate grid is v + w = u.
