e reason why.
k(x) = –3x6 – 0.7x + x3

A. Yes; degree 10
B. No, because some range elements correspond to more than one domain element
C. No, because 0.7 isn't an integer

ANSWER


The correct answer is option D.


EXPLANATION


The given function is



k(x)=-3x^6-0.7x+x^3



This a polynomial function. All degrees are greater than or equal to zero.


The coefficient being decimals does not disqualify it from being a polynomial.


The highest degree of this polynomial is 6.


Therefore the correct answer is D

A circle has centre (3,0) and radius 5. The line y = 2x + k intersects the circle in two points. Find the set
lara [203]

A circle with center (3,0) and radius 5 has equation

(x-3)^2+y^2=25 \iff x^2 + y^2- 6 x  = 16

If we substitute y=2x+k in this equation, we have

x^2+(2x+k)^2-6x=16 \iff 5x^2+(4k-6)x+k^2-16=0

This equation has two solutions (i.e. the line intersects the circle in two points) if and only if the determinant is greater than zero:

\Delta=b^2-4ac=(4k-6)^2-4\cdot 5\cdot (k^2-16)>0

The expression simplifies to

-4 (k^2 + 12 k - 89)>0 \iff k^2 + 12 k - 89

The solutions to the associated equation are

k^2 + 12 k - 89=0 \iff k=-6\pm 5\sqrt{5}

So, the parabola is negative between the two solutions:

-6-5\sqrt{5}

Natalie saved $20 when she purchased a new phone.The phone originally cost $125.What percent savings did Natalie receive on the
maw [93]

  x         20
------ = -------
100      125

(The percentage x saved is equal to 20 out of 120) Cross multiply:
125x = 20(100)
125x = 2000
Divide both sides by 125
x = 16%

Find the polar equation of the conic with the focus at the pole, directrix x = -5, and eccentricity 2.
prohojiy [21]

Step-by-step explanation:

Given that,

Directrix, d= -5, and eccentricity, e = 2.

The polar equation of the conic is given by :

r=\dfrac{ed}{1-e\cos\theta}

Put all the values,

r=\dfrac{-5\times 2}{1-2\cos\theta}\\\\=\dfrac{-10}{1-2\cos\theta}

As e>1, it is a hyperbola. Hence, this is the required solution.
