If you observe carefully, you can see that the graph is crossing x-axis at the points 1 and 9. This means x = 1 and x = 9 are the roots of the polynomials and x - 1 and x - 9 are thus the factors of the polynomial.

We can express the polynomial as the product of its factors. So the above polynomial can be expressed as (x - 1)(x - 9)

Thus, the answer to the question is option D

What value of x satisfies
LenaWriter [7]

Answer:

See explanation

Step-by-step explanation:

The given trigonometric equation is cos(90-x)=-\frac{\sqrt{3} }{3}.

We take the inverse cosine of both sides to get:

90-x=cos^{-1}(-\frac{\sqrt{3} }{3})

90-x=125

x=125-90

x=-35\degree=325\degree to the nearest degree

None of the options satisfies the given equation.

But if the question is actually;

cos(90-x)=-\frac{\sqrt{3} }{2}

Then;

90-x=\cos^{-1}(-\frac{\sqrt{3} }{2}).

90-x=210.

90-x=210.

x=-120\degree.

Or

x=360-120=240\degree.

In this case the answer will be B

A new car's original price is $13,999. If it's on sale<br> for 10% off, what's the new price?
blsea [12.9K]
To find new price after discount we are going to find 10% of $13,999.00, then subtract the discount amount from $13,999.00.

13,999.00 × ¹⁰/₁₀₀ = $1,399.90

13,999.00 - 1,399.90 = $12,599.10

Therefore, new price = $12,599.10

Determine if 2x = 14 + y and 4x + 2y = 10 are parallel, perpendicular, or neither.
kozerog [31]

Answer:

Neither

Step-by-step explanation:

To tell if lines are perpendicular or parallel just from the equations, you need to look at the slopes. So get the equations into slop-intercept form

(y = slope * x + y-intercept)

2x = 14 + y

-14          -14

2x - 14 = y    OR     y = 2x - 14

*So the slope of the first equation is 2*

4x + 2y = 10

-4x           -4x

2y = -4x + 10

/2          /2

y = -4/2 + 10

*So the slope is -2*

For the lines to be parallel, the slopes have to be the same. For them to be perpendicular, the slopes have to be opposite (negative is the opposite of positive and vice versa) and reciprocal (A flipped fraction, so the reciprocal of 2 would be 1/2)
