Immediately, we can factor an x out of each term to simplify the polynomial.

x(x^2 + 2x - 24)

In doing this, we know the first zero will be x = 0.

Using the AC method, we can find the next two zeros.

x(x - 4)(x + 6)

The zeros of the polynomial function f(x) = x^3 + 2x^2 -24x are x = -6, 0, and 4.

The question requires finding the zeros of the polynomial function f(x) = x^3 + 2x^2 -24x. The zeros of this function can be found by setting the function equal to zero and solving for x. So, we have 0 = x^3 + 2x^2 - 24x. All terms have an 'x', so we can factor out 'x' to give: 0 = x (x^2 + 2x - 24). The quadratic formula (which is used for expressions of the form ax^2 + bx + c = 0) to solve x^2 + 2x - 24 = 0, we get x = -6 and x = 4. Therefore, the zeros of the function are x = -6, 0, and 4.

Answer:

p=1.2

Step-by-step explanation:

Additive inverse of any number means a number which can be added to the original number to get

Two numbers are said to be additive inverse of each other if sum of both numbers is 0. For example if 5 is the given number then -5 will be it's additive inverse. So to find additive inverse, we basically change the sign of number.

Given number p is additive inverse off -1.2 so p must be 1.2.

Sum will obviously be 0.

So to graph them on number line, we make a point at -1.2, 1.2 and at 0 for their sum.

Answer:

1 and 3/4 days are equal to 42 hours

Step-by-step explanation:

42 hours = (42 hours) (1 day / 24 hours)

42 hours = 42/24 days

Simplyfing the fraction: Dividing the numerator and denominator by 6:

42 hours = (42/6) /  (24/6) days

42 hours = 7/4 days

42 hours = (4+3)/4 days

42 hours = (4/4+3/4) days

42 hours = 1 3/4 days

To determine how many days are equal to 42 hours, you divide 42 by 24 which results in 1.75. Therefore, 42 hours is equivalent to 1 and 3/4 days.

In this mathematics problem, we are asked to convert 42 hours into a measurement of days. To begin with, we know that 1 day equals 24 hours. Therefore, to convert 42 hours into days we will divide 42 by 24.

The result of this division is 1.75. In terms of a day fraction, this value represents 1 and 3/4 days. As such, we can say that 42 hours is equivalent to 1 and 3/4 days.

Answer: q²x² - p³x + 3pqx + q = 0

Step-by-step explanation:

Since a and B are the roots of x² - px + q = 0, then x = a and x = B

⇒ (x - a)(x - B) = 0

⇒ x² - ax - Bx + aB = 0

⇒ x² - (a + B)x + aB = 0

Comparing this to the given equation of x² - px + q = 0, we discover that

Next, given the roots for the new equation as [tex]x = \dfrac{a}{B^2} \quad\text{and}\quad\ x=\dfrac{B}{a^2}[/tex]

⇒ [tex]\bigg(x - \dfrac{a}{B^2}\bigg)\bigg(x-\dfrac{B}{a^2}\bigg)=0[/tex]

⇒ (B²x - a)(a²x - B) = 0

⇒ a²B²x² - a³x - B³x + aB = 0

⇒ a²B²x² - (a³ + B³)x + aB = 0

Let's look at each term individually:

1st term: a²B²x² = (aB)²x²   = q²x²  (since q = aB)

2nd term: (a³ + B³)x  cubic formula can be used

             = [(a + B)(a² - aB + B²)]x

              = [(a + B)(a² + (2aB - 3aB) + B²)]x

              = [(a + B)(a² + 2aB + B² - 3aB)]x

              = [(a + B)(a + B)² - 3aB)]x

              = [(   p   )(  p²     -  3 q      )]x      since p = a + B and q = aB

              = (p³ - 3pq)x       distributed "p" into p² - 3q

              = p³x - 3pqx       distributed "x" into p³ - 3pq

3rd term: aB = q       since q = aB  

Put it all together:

   q²x² - (p³x - 3pqx) + q = 0

⇒ q²x² - p³x + 3pqx + q = 0

Answer:

The second option is correct. The point slope form of AB is [tex]y+1=\frac{-3}{2}(x-1)[/tex].

Step-by-step explanation:

The given points are A(-3,5) and B(1,-1).

Slope of a line is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of AB is

[tex]m=\frac{-1-5}{1-(-3)}[/tex]

[tex]m=\frac{-6}{4}[/tex]

[tex]m=\frac{-3}{2}[/tex]

The point slope form of a line is

[tex]y-y_1=m(x-x_1)[/tex]

Where, m is slope of the line.

Case 1: The slope of the line is [tex]\frac{-3}{2}[/tex] and the point is (-3,5). The point slope form of AB is

[tex]y-5=\frac{-3}{2}(x+3)[/tex]

Case 1: The slope of the line is [tex]\frac{-3}{2}[/tex] and the point is (1,-1). The point slope form of AB is

[tex]y+1=\frac{-3}{2}(x-1)[/tex]

Therefore the point slope form of AB is [tex]y+1=\frac{-3}{2}(x-1)[/tex]. Option 2 is correct.

Answer:

in the point slop form y=2x+8

the slope is 2

the y intercept is 8

The slope-intercept form of line:

y = mx + b

m - slope

b - y-intercept

We have y = 2x + 8. Therefore:

slope m = 2

y-intercept b = 8

Answer:

x=9

Step-by-step explanation:

2x+3y =36

We know y =6, so we can substitute this into the equation

2x+ 3(6) = 36

2x+18 = 36

Subtract 18 from each side

2x+18-18 = 36-18

2x =18

Divide each side by 2

2x/2 =18/2

x=9

Answer:

x² + y² = 5

Step-by-step explanation:

The circle with center (h, k) and radius r has equation ...

... (x -h)² + (y -k)² = r²

You can find r² using the Pythagorean theorem or the distance formula, or you can simply calculate what it needs to be to make one or the other of the points lie on the circle.

For (h, k) = (0, 0), the equation is ...

... (x -0)² + (y -0)² = r²

Using (-1, 2) for (x, y), we can find r² as ...

... (-1 -0)² + (2 -0)² = r² = 1 + 4 = 5

Then the circle equation is ...

... x² + y² = 5

Answer: 200 yards

Step-by-step explanation:

So if 3/4 inches on the map is equal to 50 yards then you could divide the 3 inch distance from him to his home by 3/4 and then multiply that answer by 50. So 3 ÷ 3/4 = 4. 4 * 50 = 200. He is 200 yards from his home.

Answer:

Step-by-step explanation:

To solve this problem, we use the rule of three, if 50 yards represents 3/4 inches, how many yards would represent 3 inches?

[tex]x=3in\frac{50yd}{\frac{3}{4}in } =3\frac{200}{3}yd=200yd[/tex]

So, 3 inches represents 200 yards, that means Harper is 200 yards away home.

Remember that the rule of three is just about using the ratio that the problem already gave.

Therefore, the answer is 200 yards.

Step-by-step explanation:

Z-score = (score - mean)  / standard deviation

98 is the highest score and its z-score is (98- 81.5) / 9.3

= 1.7742

Answer: 1.77

Step-by-step explanation:

Given : The test grades of a science class are given.

78, 75, 70, 92, 69, 83, 98, 76, 75, 82, 91, 89

The grades are normally distributed with a mean [tex]\mu= 81.5[/tex] and a standard deviation [tex]\sigma=9.3[/tex] .

let x be any random variable represents the test grades of a science class.

Formula for z-score:-

[tex]z=\dfrac{x-\mu}{\sigma}[/tex]

The highest score= 98

Then , the z-score of the highest grade in the test will be :-

[tex]z=\dfrac{98-81.5}{9.3}=1.77419354839\approx1.77[/tex]

Hence, the z-score of the highest grade in the test =1.77

Answer: 25%

Step-by-step explanation:

Hi, if you buy 2 sweaters at full price (100%)

$48 x 2 = $96

"Buy one get one 1/2 off sale"´price

48 + (48/2) = 48 +24 = $72

So, the normal price for both sweaters (96) multiplied by a percentage is equal to the "buy one get one 1/2 off sale” price.

96 x =72

x =72/96 = 0.75  

Multiplying by 100 to obtain the percentage form

0.75 =75%

So, the sale price is %75 of the full price.

To obtain the percent discount.

100%-75% = 25%

You would need 12 gallons of paint A. You can find this answer by finding what 60% of 20 is, and do that by multiplying 20 • (0.6). This is what gives you 12. Following that, you’ll need 3 gallons of C, and 5 gallons of B.
