You borrow $30,000 to buy a new car. The simple interest
bagirrra123 [75]

Answer:

I think you have a typo in the interest rate. If you want to calculate the interest on $30000 at 2% interest per year after 5 years, the answer is $3,000. If you want to calculate the interest on $30000 at 5% interest per year after 5 years,  the answer is $7500.

Step-by-step explanation:

I think you have a typo in the interest rate. If you want to calculate the interest on $30000 at 2% interest per year after 5 years, this is the correct answer:

The formula we'll use for this is the simple interest formula, or:

P= I × r × t

Where...

P equals the principal amount, which is $30000.00.

r equals interest rate, which in this case is 2% per year, or in decimal form, 2/100=0.02.

t equals time involved, which would be 5 years.

To find the simple interest, we multiply 30000 × 0.02 × 5 to get that the interest is: $3000.00

Now, if you want to calculate the interest on $30000 at 5% interest per year after 5 years, this is the correct answer:

The formula we'll use for this is the simple interest formula, or:

P= I × r × t

Where...

P equals the principal amount, which is $30000.00.

r equals interest rate, which in this case is 5% per year, or in decimal form, 5/100=0.05.

t equals time involved, which would be 5 years.

To find the simple interest, we multiply 30000 × 0.05 × 5 to get that the interest is $7500.00.

hope this helped! will you pls give a "thanks" and/or leave a brainllest since I had to do two different equations? :)

Find the value of x^3 + y^3 + z^3 – 3xyz if x^2 + y^2 + z^2 = 83 and x + y + z = 15​
daser333 [38]

Answer:

180

Step-by-step explanation:

Consider the equation x + y + z = 15

From algebraic identities, we know that (a + b + c)^2 = a^2 + b^2 + c^2 + 2(ab + bc + ca)

So,

(x + y + z)^2 = x^2 + y^2 + z^2 + 2(xy + yz + xz)

From the question, x^2 + y^2 + z^2 = 83 and x + y + z = 15

So,

152 = 83 + 2(xy + yz + xz)

=> 225 – 83 = 2(xy + yz + xz)

Or, xy + yz + xz = 142/2 = 71

Using algebraic identity a³ + b³ + c³ – 3abc = (a + b + c)(a² + b² + c² – ab – bc – ca),

x3 + y3 + z3 – 3xyz = (x + y + z)(x² + y² + z² – (xy + yz + xz))

Now,

x + y + z = 15, x² + y² + z² = 83 and xy + yz + xz = 71

So, x^3 + y^3 + z^3 – 3xyz = 15(83 – 71)

=> x^3 + y^3 + z^3 – 3xyz = 15 × 12

Or, x^3 + y^3 + z^3 – 3xyz = 180
