Answer:
$27508
Step-by-step explanation:
The value of a truck v(x) in dollars after x years is modeled by the equation
.
Now, this is an exponential decay function, where the price of the truck is depreciating at an exponential rate.
So, after 2 years the value of the truck will become
dollars. (Answer)
Answer:
2(r+4)(r-4)
Step-by-step explanation
First, you want to factor out 2 from both terms, which gives you 2(r^2-16). Then you want to recognize that (r^2-16) is factorable into 2 terms. If you multiply (r+4) by (r-4) then you are given (r^2-16) as a result.
Write out in math symbols the info given you here: if the product of d and x is 14, then x = 14/d.
Answer:
The equation is;
4y = 7x + 2
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
m = (y2-y1)/(x2-x1)
(x1,y1) = (2,3)
(x2,y2) = (-2,-4)
m = (-4-3)/(-2-2) = -7/-4 = 7/4
So we have the equation as;
y = 7x/4 + b
To
get the value of b, we will substitute any of the points (let us use 2,3)
We simply substitute 2 for x and 3 for y
We have this as:
3= 7(2)/4 + b
3 = 7/2 + b
b = 3-7/2 = -1/2
So we have the equation as;
y = 7x/4 + 1/2
multiply through by 4
4y = 7x + 2
Answer:
Total number of orange trees = 77 trees
Step-by-step explanation:
Given:
Total number of rows = 15
Total number of cherry rows = 4
Number of trees in each rows = 7
Find:
Total number of orange trees
Computation:
Total number of orange trees = [Total number of rows - Total number of cherry rows][Number of trees in each rows]
Total number of orange trees = [15 - 4]7
Total number of orange trees = [11]7
Total number of orange trees = 77 trees
