The value of a car is decreasing by 14% per year. If the car is worth 11,000 today, what will it be worth in two years?

Xelga [282]

For us to be able to determine the worth of the car in two years, we will be using the depreciation formula:

$\text{ FV = PV(1 - }\frac{r}{100})^n$

Where,

PV = Current value of the car

r = rate of interest

n = number of years

FV = Future value

Given:

PV = 11,000

r = 14%

n = 2 years

We get,

$\text{ FV = PV(1 - }\frac{r}{100})^n$ $\text{= (11,000)(1 - }\frac{14}{100})^2$ $\text{= (11,000)(1 - }0.14)^2$ $\text{= (11,000)(}0.86)^2$ $\text{= (11,000)(}0.7396)$ $=\text{ 8,135.60}$

Therefore, the answer is 8,135.60

Caleb bought groceries and paid $1.60 in sales tax. The sales tax rate is 2.5%. What was the price of Caleb´s groceries before t

____ [38]

Answer:

Let x be the price of the groceries:

x × 0.25 = 1.60

x = 1.60/0.25

x = $6.40

$6.40 - $1.60 = $4.80

Step-by-step explanation:

Hhaah! My name is Caleb lolll :)

Mark as brainliest please! :)

Use differentials to estimate the amount of material in a closed cylindrical can that is 60 cm high and 24 cm in diameter if the

alexira [117]

Answer:

$dV=542.9 cm^{3}$

Step-by-step explanation:

Let's start with the equation of the volume of a cylinder:

$V=\pi r^{2}*h$

Where:

r is the radius of the cylinder (r=D/2=24/2=12 cm)
h is the high of the cylinder (h = 60 cm)

We can us partial derivatives to find the differential of this volume. So we will have:

$dV=\frac{\partial V}{\partial r}dr+\frac{\partial V}{\partial h}dh$ (1)

Now:

$\frac{\partial V}{\partial r}=2\pi r*h=2\pi 12*60=4523.9 cm^{2}$

$\frac{\partial V}{\partial h}=\pi 12^{2}=452.4 cm^{2}$

dr is a differential of the radius, so in our case it is 0.1 cm and dh, differential of the high, is 0.1*2 cm. We multiply by 2 because we need to consider the top and the bottom of the cylinder.

Now we just need to put all of this definitions in the equation (1).

$dV=4523.9*0.1+452.4*0.2=542.9 cm^{3}$

I hope it helps you!

Ryan, a baker, measured the weights of cakes baked in each batch at his bakery and found that the mean weight of each cake is 50

denpristay [2]

Answer: Rejecting the mean weight of each cake as 500 gram when H subscript 0 equals 500

Step-by-step explanation:

Given that :

Null hypothesis : H0 =500

Alternative hypothesis : Ha < 500

Type 1 Error: Type 1 error simply occurs when we reject the Null hypothesis when the Null is true. Alternatively, type 11 error occurs when we fail to reject a false null hypothesis.

Hence, in the scenario above, a type 1 error will occur when we reject the mean weight as 500 even though the Null hypothesis is True.
