Jackson purchases a new car for $48,000. The car's value can be modeled by the

vekshin1

We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the following exponential function: $y = 48000(0.76)^t$ where y represents the car's value and t represents time in years. We are asked to find the decay rate as a percentage.

We know that an exponential decay function is in form $y=a\cdot (1-r)^x$ , where,

y = Final value,

a = Initial value,

r = Decay rate in decimal form,

x = time.

Upon comparing our given function $y = 48000(0.76)^t$ with standard decay function $y=a\cdot (1-r)^x$ , we can see that $1-r=0.76$ .

Let us solve for r.

$1-1-r=0.76-1$

$-r=-0.24$

$r=0.24$

Let us convert 0.24 into percentage.

$0.24\times 100\%=24\%$

Therefore, the decay rate is 24%.

Write the equation of the line that passes through (1, 3) and has a slope of 2 in point-slope form

raketka [301]

Answer:

y-3= 2(x-1)

Step-by-step explanation:

1. The equation of a line in point slope form is y-y1= m(x-x1)

2. m=slope and (x1,y1) is the point the line passes through

3. The point the line passes through is (1,3)

4, The slope is 2

5. Therefore the answer is y-3=2(x-1)

What is a true statement about negative exponents?

Nadya [2.5K]

Answer:

Raising something to a negative exponent is just taking the reciprocal of the amount.

Step-by-step explanation:

Let's assume that you wanted to know what $x^{-2}$ is.

To find it, you would take the reciprocal of the x amount. So $x^{-2}$ becomes $\frac{1}{x^{2}}$ .

This works because of the nature of exponents. Exponents represent the number of times you are multiplying a value by itself. So $a^{3}$ would be equal to a · a · a. To increase the exponent, you increase the number of times the value is multiplied by itself: To increase $a^{3}$ to $a^{5}$ , you would have to multiply a with $a^{3}$ two more times (a · a · a · a · a). To decrease the exponent, you must divide the value by itself. So to decrease $a^{5}$ to $a^{2}$ , you would have to divide $a^{5}$ by a 3 times.

If the exponent is 0, the value is equal to 1. But you can still decrease the exponent into negative numbers. You just divide 1 by a the desired amount of times: $\frac{1}{a^{3}}$ means that you are dividing 1 by a 3 times.

Hope this helps.

1) A book contains 192 pages. A boy reads x complete pages everyday.if he has not finished the book after 10days, find the highe

dlinn [17]

Answer:

19

Step-by-step explanation:

After x days, the boy will have read 10x. If this is less than 192, we have ...

10x < 192

x < 192/10

x < 19.2

If x is an integer, the largest possible value x could have is 19.
