dan buys a car for £2,200 it depreciates at a rate of 0.5% per year how much would it be worth in 6 years
Given:
The initial value of car = £2,200
Depreciation rate = 0.5%
To find:
The worth of car after 6 years.
Solution:
Exponential decay model:
[tex]y=a(1-r)^t[/tex]
Where, a is the initial value, r is the rate of depreciation and t is number of years.
Putting a=2200, r=0.005 and t=6, we get
[tex]y=2200(1-0.005)^6[/tex]
[tex]y=2200(0.995)^6[/tex]
[tex]y=2200(0.9703725)[/tex]
[tex]y=2134.8195[/tex]
[tex]y\approx 2134.82[/tex]
Therefore, the worth of the car after 6 years is £2134.82.

How many terms can 5x+9-4b have
Answer:
8x
Step-by-step explanation:
The constants are the numbers that are NOT
attached to anything. In the expression, 3x + 2,
(2) is a constant because it is not attached to
anything. The (3) is not a constant because it
is attached to x, and it is actually a coefficient.
Please help and I please don't answer just for the points I'll report you
Answer:
x=1
y=1
Step-by-step explanation:
y=x^2-x+1 1. Write out the equation
y=y^2-y+1 2. Substitute the "x"s for "y"s
0=y^2-2y+1 3. Subtract "y" from both sides of the equation
0=(y-1)(y-1) 4. Factor into a binomial
y-1=0
y=1
x=1

Solve it down here
Answer:
n = -20
Step-by-step explanation:
-7 + [tex]\frac{n}{5}[/tex] = -11
*multiply both sides by 5*
-35 + n = -55
*add 35 to each side*
n = -55 + 35
*calculate the sum*
n = -20

Carlos needs 2/3 cups of raisins to make one batch of oatmeal bars. How many cups of raisins does Carlos need to makes batches of oatmeal bars? Select the correct answer.
Answer: 2²/₃ cups of raisins.
Step-by-step explanation:
Question wants to know the number of cups needed for 4 batches of oatmeal bars.
Each batch needs 2/3 cups of raisins to make.
If there are 4 batches to be made therefore, one must multiple the 2/3 cups to make one batch by 4 to find out the number needed to make 4 batches.
= 2/3 * 4
= 8/3
= 2²/₃ cups of raisins.

write the equation for this line
If this is for slope-intercept, the equation is: y = 3x + 1
To find the slope, you would find the rise over run ( [tex]\frac{rise}{run}[/tex] ). So, you would start where the graph intersect at the y-axis, which is 1. You would go up 3 times, and right 1 time. So, [tex]\frac{3}{1}[/tex], or 3, would be your slope. To find the y-intercept, you would need to find where the graph intersects at the y-axis, which is 1, so it would be your y-intercept. Plug them into the y = mx + b formula and the answer is y = 3x + 1.

What is the end behavior f(x) ?
[tex]\text{ as } x \to \infty, \ f(x) \to \infty\\\\\text{ as } x \to -\infty, \ f(x) \to -\infty[/tex]
In other words, as x gets really large in the positive direction, so does f(x).
As x gets really large in the negative direction, so does f(x). We can see that x and f(x) move in the same direction toward the same type of infinity.
In laymen's terms or in plain English, we can say that "The graph falls to the left and rises to the right". We don't worry about the wiggle motion in the middle, since all we care about is what's going on as x goes to either infinity.
"Falls to the left" means it goes down forever as we move leftward. "Rises to the right" means it goes up forever as we move to the right. This type of behavior of "falls to the left and rises to the right" is indicative of any odd degree polynomial where the leading coefficient is positive. In this case, it appears we're dealing with a cubic function of degree 3.

Rob owes his father $18.
Step-by-step explanation:
Rob has to pay back the same amount of money that he took. Since he took 15 dollars, he has to give back 15 dollars which makes the 15 negative. The same goes for the 3 in the equation.
To find out the total amount Rob has to pay back, we have to add -15 and -3, which is -18.
