Which is a third degree polynomial with –3 and 2 as its only zeros?

x^2 + x – 6
x^3 + 2x^2 – 5x – 6
x^3 + 4x^2 – 3x – 18
x^3 + x^2 – 8x– 12

Answers

Answer 1
Let's think about it for a sec. It can't be A for obvious reasons. Now let's think what makes (X+3)(X-2)? the obvious answer is B, but don't be fooled. The zeros would be 2(X-3)(X-2) which doesn't make sense. It can't be D because the zeros of that (after solving is) (x-6)(x-2) which doesnt make sense.

therefore the answer is B. you can always just graph it too.
Answer 2
Final answer:

The third-degree polynomial with – 3 and 2 as its only zeros is x³ + x² – 8x – 12, which can be factored as (x+3)(x-2)(x-2).

Explanation:

A third-degree polynomial with – 3 and 2 as its only zeros must be in the format of A(x+3)(x-2)(x-C), where A and C are constants, and C is possibly another zero of the polynomial.

Given the four options, the only polynomial that fits this format and has – 3 and 2 as zeros is x³ + x² – 8x – 12.

To verify, we can factor it: (x+3)(x-2)(x-2), which shows that 2 is a zero of multiplicity 2, and – 3 is also a zero.

There are no other real zeros besides these, so it is the correct polynomial.

find an equation with vertical asymptotes 1 and 4 and horizontal asymptote 1 please help

Answers

Answer:

y = 1 + 1/((x -1)(x -4))

Step-by-step explanation:

To get vertical asymptotes at 1 and 4, you need factors (x -1) and (x -4) in the denominator. As x approaches 1 or 4, one of these will approach zero, and the function value will approach infinity.

To get a horizontal asymptote of 1, the function must approach the value 1 when the value of x gets large (positive or negative). This can generally be accomplished by simply adding 1 to a fraction that approaches zero when x is large.

Here, we make the fraction be the one that gives the vertical asymptotes, and we simply add 1 to it.

... y = 1 + 1/((x -1)(x -4))

If you like, this can be "simplified" to ...

... y = (x² -5x +5)/(x² -5x +4)

_____

In this rational expression form, please note that the numerator and denominator have the same degree. That will be the case when there is a horizontal asymptote. (When a slant asymptote, the numerator degree is 1 higher than the denominator.) The ratio of the coefficients of the highest degree terms is the horizontal asymptote value (or the slope of a slant asymptote).

Answers

Answer:

6 2/3 hours

Step-by-step explanation:

We assume the time of interest is the total time spent on the main road and side road.

In each case, ...

... time = distance/speed

On the main road, ...

... tmain = s/v

On the side road, ...

... tside = (2s)/(v -2)

Then the total time spent is ...

... ttotal = tmain + tside

... = s/v + (2s)/(v -2)

For s=10 and v=6, this is ...

... ttotal = 10/6 + 2·10/(6 -2) = 5/3 + 20/4 = 5/3 + 5 . . . . hours

Step-by-step explanation:

1. First differences in the y-values are ...

... -5-0 = -5; -8-(-5) = -3; -9-(-8) = -1; -8-(-9) = 1; -5-(-8) = 3; 0-(-5) = 5

Second differences are ...

... -3-(-5) = 2; -1-(-3) = 2; 1-(-1) = 2; 3-1 = 2; 5-3 = 2

These 2nd differences are constant, so the points can be described by a 2nd-degree polynomial.

2. Values on the graph range from 0 to a low of -9 and back up to 0. There is a minimum at (1, -9).

3. The value at x=-1 is -5; at x=1, it is -9, which is less than -5. The function is decreasing on the interval -1 to 1.

Which equation has the same solution as this equation? x^2-16x+12=0

Answers

Final answer:

Another equation that shares the same solutions as x²-16x+12=0 is 2x² - 32x + 24 = 0. This equation is the initial equation multiplied by 2 and thus would produce the same solutions when the quadratic formula is applied.

Explanation:

The equation given is a quadratic equation, which is in the form ax²+bx+c = 0. The solutions of a quadratic equation are given by the formula: -b ± √b² - 4ac / 2a. This formula can be used to find the solutions of any other quadratic equation. For the given equation, x²-16x+12=0, the values of a, b, and c are 1, -16, and 12 respectively. So, another equation with the same solutions could be 2x² - 32x + 24 = 0. This equation has the same solutions because it's simply the initial equation multiplied by 2, so this doesn't change the results of the quadratic formula.

Step-by-step explanation:

The chip is 14  nanometers

14 * .000000001

.000000014

Move the decimal 8 places to the right, because we need 1 number in front of the decimal for scientific notation.  The exponent will be -8 because  we moved it 8 places to the right

1.4 × 10^-8

Final answer:

The thickness of the silicon chip in scientific notation is 1.4 x 10^-8 m.

Explanation:

To express the thickness of the silicon chip in scientific notation, we need to convert the given thickness of 14 nanometers to meters.

Since 1 nanometer (nm) is equal to 0.000000001 meters, we can convert 14 nanometers to meters by multiplying it by the conversion factor:

14 nm x 0.000000001 m/nm = 0.000000014 m

Now, we can express the thickness of the chip in scientific notation:

0.000000014 m = 1.4 x 10-8 m

How much water must be evaporated from 20 gallons of a 10% salt solution in order to obtain a 20% salt solution?

Answers

Answer:

8 gallons have to be evaporated to have a 20% salt solution.


hope this helped :)

Step-by-step explanation:

.10*20=2 gallons of salt.

That leaves 18 gallons of water.


.2x=2


x=2/.2


x=10 gallons after evaporation.


18-10=8

Final answer:

To obtain a 20% salt solution from a 10% salt solution, 20 gallons of water must be evaporated.

Explanation:

To obtain a 20% salt solution from a 10% salt solution, the amount of water that needs to be evaporated can be calculated using a proportion. First, convert the percentages to decimals by dividing them by 100. Let x be the amount of water to be evaporated. The amount of salt in the initial solution is 10% of 20 gallons, or 0.10 * 20 = 2 gallons. The resulting solution will have 20% salt in a total volume of 20 - x gallons. Set up a proportion:

(2 gallons)/(20 gallons) = (0.20 * (20 - x) gallons)/(20 - x gallons)

Cross multiply and solve for x:

2(20 - x) = 0.20(20 - x)

Now solve the equation:

40 - 2x = 4 - 0.20x

2x - 0.20x = 40 - 4

1.8x = 36

x = 36/1.8

x = 20

Therefore, 20 gallons of water must be evaporated from the initial 20-gallon solution to obtain a 20% salt solution.

f(x) is an exponential function.

Lim x→∞ f(x) = Lim x→∞ (-5^x+2) = -5^(∞)+2 = -∞+2→ Lim x→∞ f(x) = -∞

Lim x→ -∞ f(x) = Lim x→ -∞ (-5^x+2) = -5^(-∞)+2 = -1/5^∞+2 = -1/∞+2 = 0+2→

A linear function is one that can be written in the form [tex]\( y = mx + b \)[/tex], where [tex]\( m \)[/tex] and [tex]\( b \)[/tex] are constants, and [tex]\( x \)[/tex] is the independent variable. The graph of a linear function is a straight line.

2. The function [tex]\( y = 23 \)[/tex] is a constant function. Although it does not have an [tex]\( x \)[/tex] term, it can still be considered linear because it can be written as [tex]\( y = 0x + 23 \)[/tex], where the slope [tex]\( m = 0 \)[/tex] and the y-intercept [tex]\( b = 23 \)[/tex]. The graph of this function is a horizontal line, which is a special case of a linear function.

3. The function [tex]\( y = 1 - 2x^2 \)[/tex] contains an [tex]\( x^2 \)[/tex] term, which makes it a quadratic function. Quadratic functions are nonlinear because their graphs are parabolas, not straight lines. The presence of the [tex]\( x^2 \)[/tex] term means that the rate of change of [tex]\( y \)[/tex] with respect to [tex]\( x \)[/tex] is not constant, which is a key characteristic of nonlinear functions. Therefore, this function is nonlinear.

= [tex]\frac{1}{3} \pi r^{2} h+\frac{2}{3} \pi r^{3}[/tex]

substitute for h and r in the equation

Required volume =

[tex][tex]\frac{1}{3}\pi  r^{2} (h+2r) = \frac{1}{3}\pi  9^{2} (17+2(9))\\= 1441.99+1526.31\\=2968.30[/tex][/tex]

So answer is 2968.30 cm cube.

Parker and Company pays Selma Stokes on a variable commission scale. In a month when Selma had net sales of $155,000, what was her Gross Pay based on the following scale?

Net Sales Commission Rate
Up to $40,000 5%
Excess of $40,000 to $75,000 5.5%
Excess of $75,000 to $100,000 6%
More than $100,000 7%

Answers

Answer:

$9275

Step-by-step explanation:

Selma earns 5% on the first $40,000, which is $2000.

She earns 5.5% on the next $35,000, which is $1925.

She earns 6% on the next $25,000, which is $1500.

And she earns 7% on the last $55,000 (the amount over 100,000), which is $3850.

Altogether, Selma's commission is ...

... $2000 +1925 +1500 +3850 = $9275.

Final answer:

There are 121 students in 9th grade and 115 students in 10th grade at Jefferson High School.

Explanation:

This question involves counting and analyzing data about grade levels and handedness of students at Jefferson High School. To answer the question, we need to use the given information:

- There are 236 students in 9th and 10th grades combined.

- Out of these, 121 students are in 9th grade.

- Among the 214 right-handed students, 103 are in 10th grade.

We can use these numbers to find out how many students are in each grade level.

Let's denote the number of 9th-grade students as 'x' and 10th-grade students as 'y'.

From the given information:

x + y = 236 (total number of students)

x = 121 (number of 9th-grade students)

y = 103 (number of 10th-grade students)

To find the value of 'y', we can substitute the given value of 'x' into the first equation:

121 + y = 236

y = 236 - 121

y = 115

Therefore, there are 121 students in 9th grade and 115 students in 10th grade.
