laiz [17]

Answer:

1 Batch... i think.

Step-by-step explanation:

So, like, half of 15 is 7.5. That makes two batches. I don't think we're supposed to say 0.5=1 batch here, cause that is unrealistic.

Find the missing number in this proportion <br> Help

Triss [41]

Answer:

Step-by-step explanation:

To solve, we can first cross multiply

28/63=4/x

28*x=63*4

28x=252

Since we are trying to find x(the missing number), we need to get x by itself. x is being multiplied by 28. To undo this, divide both sides by 28. This will cancel out 28 and leave x by itself.

28x/28=252/28

x=9

So, the missing number is 9

28/63=4/9

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. W

Tems11 [23]

Answer:

Hence, the polynomial function in standard form is:

$f(x)=x^3 - 12x^2 + 46x - 52$

Step-by-step explanation:

We are given a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros 2,5-i.

As we know that the polynomial function has rational coefficients.

so any complex root always appear in pair.

so as 5-i is a root of f(x) then it's complex conjugate 5+i is also an root of f(x).

Hence f(x) could be represented as:

$f(x)= (x-2)[x-(5-i)][x-(5+i)]\\\\f(x) = (x - 2)[(x-5)+ i][(x-5)- i)\\\\f(x)= (x - 2)[(x-5)^2 - i^2]\\\\f(x)=(x - 2)(x^2 - 10x + 25 + 1)\\\\f(x)= (x - 2)(x^2 - 10x + 26)\\\\f(x) = x^3 - 10x^2 + 26x - 2x^2 + 20x-52\\\\f(x)=x^3 - 12x^2 + 46x - 52$

Hence, the polynomial function in standard form is:

$f(x)=x^3 - 12x^2 + 46x - 52$
