Answer:

13.6 g/ml

Step-by-step explanation:

Density is found by mass divided by volume

the polynomial ky^3+3y^2-3 and 2y^3-5y+k when divided by (y-5) leave the same remainder in each case. Find the value of k.

marshall27 [118]

Answer:

$k=\frac{153}{124}$

Step-by-step explanation:

According to the Remainder Theorem; when P(y) is divided by y-a, the remainder is p(a).

The first polynomial is :

$p(y)=ky^3+3y^2-3$

When p(y) is divided by y-5, the remainder is

$p(5)=k(5)^3+3(5)^2-3$

$p(5)=125k+75-3$

$p(5)=125k+72$

When the second polynomial:

$m(y)= 2y^3-5y+k$ is divided by y-5.

The remainder is;

$m(5)= 2(5)^3-5(5)+k$

$m(5)= 225+k$

The two remainders are equal;

$\implies 125k+72=225+k$

$\implies 125k-k=225-72$

$\implies 124k=153$

$k=\frac{153}{124}$

Hi, I'm currently a sophomore (10th grader) and my biggest advice would be don't give into peer presssure when it comes to choosing classes. Only take classes that you feel you are able to handle and succeed in, don't take high level classes just because your friends are!

Answer:

The answer is: a. 30 year FHA, 3.5% down at a fixed rate of 6.5%.

Step-by-step explanation:

If Eli wants to pay as little as possible, and we start with a 30-year mortgage, among the percentages that must be paid, the lowest is 3.5%, in terms of the fixed rate, the lowest is 5%, but if we see the amount of 30 years, it is 10%, so although the fixed rate of 6.5% is higher than that of 5%, the payment is only made once, and the difference is not so much compared to 10% for 30 years.

The answer is: a. 30 year FHA, 3.5% down at a fixed rate of 6.5%.
