Identify the data set that could be quadratic. HELP ASAP!!

Ne4ueva [31]

Answer:

Option B can be quadratic.

Step-by-step explanation:

Take a look at the data.

A quadratic equation is of the form ,

$y = ax^{2} +bx + c$ ,

where, a,b,c are constants.

To find an unknown equation of 3 variables,

we need 3 points lying on the equation.

here they have given, 5 points, meaning all should lie on the curve.

For first option, inserting first 3 points to find equation, we get equation as,

$y = x^{2} -4x +11$ , but the rest points don't satisfy the curve.

So first option is not quadratic.

Similarly, it can be shown that option C and D are also not quadratic.

While, in option B, it is clear that for every y, x is y squared,

$x = y^{2}$ , thus quadratic in nature.

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;

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

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

$\implies 124k=153$

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

There is 2 and 3/4 punds of roast beef and 1 and 7/8 pounds of turkey and 2 1/16 pounds of salami if you must put 1/4 of pound o

rosijanka [135]

2 and 3/4 punds of roast beef 2 3/4 = (4x2) + 3 /4= 11/4 roast beef

1 and 7/8 pounds of turkey 1 7/8 = 15/8 turkey

2 1/16 pounds of salami 2 1/16 33/16 salami

if you put 1/4 of pound of meat
then 11/4 roast beef divided by 1/4 = 11/4 x4 = 11 sandwiches roast beef

15/8 turkey divided 1/4 = 15/8 x 4 = 15/2 = 7 sandwishes

33/16 salami divided 1/4 = 33/16 x 4 = 33/ 4 = 8 sandwiches
