Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the zeros −3 and 5

love history [14]

Answer:

Step-by-step explanation:

Since the zeros of the equation are -3 and 5+i, hence the factors of the polynomial in x is (x+3) and (x-(5+i))

Multiplying both factors

f(x) = (x+3)(x-(5+i))

f(x) = (x²-(5+i)x+3x -3(5+i))

f(x) = x² - (5+i- 3)x -15-3i

f(x) = x² (2+i)x-15-3i

<em>hence the required polynomial function in x is f(x) = x² (2+i)x-15-3i</em>

Josie is training for a race the ratio of the number of minutes she wants to the number of miles she wants is 2043 she plans to

guajiro [1.7K]

Answer:

Josie takes 0.93 minutes to run 2 miles.

Step-by-step explanation:

We are given the following in the question:

Ratio:

Number of minutes: Number of miles = 20:43

Josie wants to run 2 miles. We have to find the number of minutes she need to run to maintain the ration.

Let x be the number of minutes Josie run.

This can be done in the following manner:

$\dfrac{20}{43} = \dfrac{x}{2}\\\\\Rightarrow x = \dfrac{20}{43}\times 2\\\\\Rightarrow x = 0.93$

Thus, Josie takes 0.93 minutes to run 2 miles.

Is (0,0) a solution to this system?

Anuta_ua [19.1K]

Answer:

option-B

Step-by-step explanation:

we are given system of inequality as

$y\leq x^2-4$

$y>2x-1$

now, we can check solution

At (0,0):

we can plug x=0 and y=0

and check inequality

$0\leq 0^2-4$

$0\leq -4$

so, this is FALSE

now, we can check second inequality

$0>2\times 0-1$

$0>-1$

So, this is TRUE

so, option-B
