Ben buys a car for $50,000. The value of the car decreases at a rate of 4% per year. How much will the car be worth in 3 years?

1 answer:

5 0

FOR THE FIRST YEAR
4/100×50000 = 2000
50,000 - 2000 = 48000
FOR THE SECOND YEAR
4/100 × 48000 = 1920
48000-1920 = 46080
FOR THE THIRD YEAR
4/100 × 46080 = 1843.2
46080-1843.2 = 44236.2

Shawn uses 45N of force to stop the cart 1 meter from running his foot over. How much work does he do?

zalisa [80]

Answer:

$\boxed {\boxed {\sf 45 \ Joules}}$

Step-by-step explanation:

Work can be found by multiplying the force by the distance traveled in the direction of the force.

$W=F*d$

The force is 45 Newtons.

The distance traveled is 1 meter.

$F=45 \ N \\d= 1 \ m$

Substitute the values into the formula.

$W=45 \ N * 1 \ m$

Multiply.

$W=45 \ N*m$

1 Newton meter is equal to 1 Joules.

Therefore our answer of 45 Newton meters is equal to 45 Joules.

$W= 45 \ J$

The work done is <u>45 Joules.</u>

A function is defined as {(0, 1), (2, 3), (5, 8), (7, 2)}. Isaac is asked to create one more ordered pair for the function. Whic

Digiron [165]

Answer:

The correct answer is 2 . (1 , 3)

Step-by-step explanation:

A function is used to denote a particular relationship between variables. They can even be visualized as an input-output machine.

Every function has a domain set and a co-domain set. A function maps elements from domain to the elements of co-domain.

Here the domain can be considered as { 0 , 2 , 5 , 7}.

Here the co- domain can be considered as { 1 , 3, 8 , 2}.

For a function to be a valid function, all elements from the domain should have an image in the co- domain and every element of domain should have exactly one image in the co-domain.

Here the options 1 , 3 and 4 violate the second necessary criteria for the function to be valid.

Hence (1 , 3) is the correct answer.

How many milliliters of 0.30% sugar solution must you add to 75mL of 4% sugar solution to get a 0.50% sugar solution?

hammer [34]

Based on the given data above, the equation below has been generated,
(X mL)(0.003) + 75 mL (0.04) = 0.005 (75 + X); X being the amount in mL of the sugar solution, by further simplification of the generated equation, it can be said that 1312.5 mL of 0.30% sugar solution should be added to 75 mL of 4% solution to come up with a 0.5% sugar solution.

Answer:

3.56*10^13

Step-by-step explanation:

8.9* 10^4 * 4*10^8

Multiply the number out front and then the exponents

8.9 * 4 * 10^4 * 10^8

When we multiply powers when the bases are the same, we add the exponents

35.6 * 10^(4+8)

35.6 *10^12

But this is not in proper scientific notation. Only one digit before the decimal

Move the decimal one place to the left, that means we need to add 1 to the exponent

3.56 *10^(12+1)

3.56 * 10^13

Write an equation of the line that passes through the given points.<br><br> (−5,−2),(−5,0)

agasfer [191]

Answer:

y=-2

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(0-(-2))/(-5-(-5))

m=(0+2)/(-5+5)

m=2/0

y-(-2)=0

y+2=0

y=0-2

y=-2
