Answer:
it is 2020
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
Differentiate each function to find an expression for its gradient (slope of the tangent line) with respect to
. Make use of the power rule to find the following:
.
.
The question states that the graphs of
and
touch at
, such that
. Therefore:
.
On the other hand, since the graph of
and
coincide at
,
(otherwise, the two graphs would not even touch at that point.) Therefore:
.
Solve this system of two equations for
and
:
.
Therefore,
whereas
.
Substitute these two values back into the expression for
and
:
.
.
Evaluate either expression at
to find the
-coordinate of the intersection. For example,
. Similarly,
.
Therefore, the intersection of these two graphs would be at
.
Down payment of the ford pickup truck = $1,900.
It is said that down payment amount $1,900 owes 75% of the selling price.
Therefore, 100-75 = 25% is the downpayment of total Selling price.
Let is assume selling price is $x.
According to problem,
25% of the selling price equals down payment amount $1,900.
Let us convert above statement into an equation.
25% of x is 1,900.
That is 25% x = 1,900.
25% could be written as 25/100 or 0.25.
So, the above equation would become
0.25x = 1,900.
Dividing both sides by 0.25, we get
0.75x/0.25 = 1,900/0.25
x=7600
So, the selling price would be $7600.
