PLEASE HELP WILL MARK BRAINLIEST..Write a polynomial function of least degree with rational coefficients so that P(x) = 0 has th
Svetlanka [38]

A polynomial function of least degree with rational coefficients so that P(x) = 0 has the given roots is P(x)=x²-5x-14

<h3>What is a polynomial function?</h3>

A function is said to as polynomial when a variable in an equation, such as a quadratic equation or cubic equation, etc., has only positive integer exponents or non-negative integer powers. One polynomial with an exponent of 1 is 2x+5, for instance. One that has more than two algebraic terms is referred to as a polynomial expression. Polynomial is a monomial or binomial that is repeatedly added, as the name suggests.

A mathematical expression containing one or more algebraic terms, where each algebraic term is made up of a constant multiplied by one or more variables raised to a nonnegative integral power.

x= -2, x=7

Given,

P(x) = 0

This polynomial function has the roots,

x= -2, x=7

So,

(x+2)(x-7)

We have to multiply both of them we get,

P(x)=(x+2)(x-7)

0=x²-5x-14

x²-5x-14=0

Therefore, P(x)=x²-5x-14 is the polynomial function.

What is the center of the circle given by the equation below?
Helen [10]

Answer:

C:  (4, 8)

Step-by-step explanation:

Rewrite the given equation x² - 8x = -y² + 16y - 44 in std. form:

                                              x² - 8x + 16 - 16 + y² - 16y + 64 =  64 - 44,  or

                                                 (x - 4)²  + (y - 8)² = 64 - 44 + 16

         Comparing this to            (x - h)² + (y - k)² = 6²

we see that h = 4 and k = 8.  The radius is 6.  The center is at (4, 8) (Answer C).

What are the sine, cosine, and tangent of Θ = 3 pi over 4 radians?
inysia [295]
Notice the "x" and "y" coordinates

the x-coordinate is well, the cosine value
the y-coordinate is well, the sine value

now the tangent

\bf tan(\theta)=\cfrac{opposite}{adjacent}=\cfrac{y}{x}\\\\&#10;-------------------------------\\\\&#10;tan(\theta )=\cfrac{\frac{\sqrt{2}}{2}}{-\frac{\sqrt{2}}{2}}\implies tan(\theta )=-1

1. Erin hits a golf ball off a tee. The height, yin yards, of the ball off the ground is given by
Sladkaya [172]

Answer:

The maximum height of the ball is 28.2 yards.

Step-by-step explanation:

When we have a quadratic equation in the following format:

y = ax^{2} + bx + c

The maximum value happens when

x = x_{v} = \frac{-b}{2a}

The maximum value will be y(x_{v})

In this problem, we have that:

y = -0.0018x^{2} + 0.45x + 0.05

So

a = -0.0018, b = 0.45, c = 0.05

x = x_{v} = \frac{-b}{2a} = \frac{-0.45}{2*(-0.0018)} = 125

The maximum height is:

y(125) = -0.0018*(125)^{2} + 0.45*125 + 0.05 = 28.2

The maximum height of the ball is 28.2 yards.

What is the value of j?<br><br>___°​
grigory [225]

<em>34 degrees. </em>

<em>If you want to find how much an angle is, first check the original line (aka base). Then (only if the line is a 180 degree line) subtract whatever value is shown (in this case it was 146 degrees so what you would do is subtract 146 from 180 and you would have your answer).</em>

<em>Hope this helps.</em>
