The polynomial function of the lowest degree that has -5, -2, and 0 as roots is f(x) = (x - 2)(x - 5).

To find the polynomial function of the lowest degree with -5, -2, and 0 as roots, we can use the factored form of a polynomial. If a number is a root of a polynomial, it means that when we substitute that number into the polynomial, the result is equal to zero.

In this case, we have the roots -5, -2, and 0. To construct the polynomial, we can write it in factored form as follows: f(x) = (x - r1)(x - r2)(x - r3), where r1, r2, and r3 are the roots.

Substituting the given roots, we have: f(x) = (x - (-5))(x - (-2))(x - 0) = (x + 5)(x + 2)(x - 0) = (x + 5)(x + 2)(x).

Simplifying further, we get: f(x) = (x^2 + 7x + 10)(x) = x^3 + 7x^2 + 10x.

Therefore, the polynomial function of the lowest degree with -5, -2, and 0 as roots is f(x) = x^3 + 7x^2 + 10x.

Answer:

  (x, y) = (4, 0)

Step-by-step explanation:

You want the solution to the system of equations ...

It often works well to start the solution process by putting both equations into standard form. We do that by removing any common factors from the coefficients. Here, we see that the second equation's coefficients each have a factor of 3, so we can remove that and rewrite the system as ...

Changing the coefficient of the y-term has no effect, telling us that y=0, and the equation reduces to ...

  5x = 20

  x = 4

More formally, if we subtract the first equation from the second, we get ...

  (5x +2y) -(5x -3y) = (20) -(20)

  5y = 0 . . . . . . simplify

  y = 0 . . . . . . . divide by 5

The solution is (x, y) = (4, 0).

Answer:

B

Step-by-step explanation:

We are given the two functions:

\(f(x) = 8 - 4x - x^3\text{ and } g(x) = x^2 + 7x - 9\)

And we want to find:

\(f(x) + g(x)\)

Substitute:

\(= (8 - 4x - x^3) + (x^2 + 7x - 9)\)

Rewrite:

\(= (-x^3) + (x^2) + (7x - 4x) + (8 - 9)\)

Combine like terms:

Answer:

625.5 cm^2

Step-by-step explanation:

The volume of a cone is

V = 1/3 B h

4170 = 1/3 B 20

4170 = 20/3 B

Multiply each side by 3/20

4170 *3/20 = B

625.5 = B

Hey there! I'm happy to help you!

The formula for the volume of a cone is V=1/3(πr²h). Now, to make it look ungibberishy and all numbery...

The volume of the cone is equal to the area of the base (the circle on the bottom whose area formula is pi multiplied by the radius squared) multiplied by the height and then divided by three.

In our case, though, we already have the volume. We need to undo the equation so that we can find the area of the circle base.

In our equation the last thing we do is divide by three. So, we will want to multiply by three to undo this.

4,170*3= 12510

The other step we took was multiply the base by the height, which is 20 centimeters.  To get our base, we will divide by the height instead!

12510/20= 625.5

Therefore, the area of the base of the cone is 625.5 centimeters squared.

I hope that this helps! Have a wonderful day!

Step-by-step explanation:

Given that the measures of the Angles of the triangle ΔXYZ are in the ratio 2:4:6.

Also, the sum of the measure of angles in a triangle is 180°.

so

2x + 4x + 6x = 180

Add similar elements: 2x + 4x + 6x = 12x

12x = 180

Divide both sides by 12

12x/12 = 180/12

Simplify

x = 15

Therefore, the measure of the angles of a triangle will be:

2x = 2(15) = 30

4x = 4(15) = 60

6x = 6(15) = 90

Verification:

30 + 60 + 90 = 180

180 = 180

26-4=22

22/2 is 11

11+4=15

15+11=26

So Sarahs age is 15 and Joe's in 11.

Answer:

Joe = 11 y/o, Sarah = 15 y/o

Step-by-step explanation:

Equation: x+(x+4) = 26

Combined ages: 2x+4=26

2x=22

x=11

So, Joe is 11.

Sarah's age: 11+4

So, Joe is 11 and Sarah is 15.

Both rational and irrational numbers are considered to be real numbers. Real numbers include all rational and irrational numbers, including integers (-2, 0, 1), fractions (1/2, 2.5), and the number 3. A rational number is any fraction with a non-zero denominator. 1/2, 1/5, 3/4, and other like numbers are a few examples of rational numbers.

Any number that can be expressed as a fraction and where the denominator (the bottom number) and the numerator (the top number) are both integers is considered a rational number. In other words, p/q, where p and q are both integers and q 0, can be used to represent a rational number.

The system of inequalities are graphed accordingly.

A system   of linear inequalities is similar to a system of linear equations, except that it is made up of inequalities  rather than equations.

For the system of inequalities y < 2(x+2)² + 3 and y > x+2, we can follow these steps ....

Graph each inequality separately on the same coordinate plane.

For   y < 2(x+2)² + 3,   we can begin by graphing y = 2(x+2)²   + 3 This is a parabola that opens upwards and has its vertex at (-2,3).

After the above   we need to determine which side of the parabola satisfies

y   < 2(x+2)² + 3

For y > x+2,     we can begin by graphing y = x+2. This is a line with a y  -intercept of 2 and a slope of    1

Next,    we need to determine which side of the line satisfies y   > x+2. .We can shade this region to indicate the solution set.

Determine the region that satisfies both inequalities by finding the overlapping shaded regions.

The region that satisfies both inequalities is the region where the shaded regions overlap. In this case, it is the region between the parabola and the line.

Identify the solution set by selecting a point in the overlapping shaded region and testing it in each inequality.

(a) If the discrimant is > 0, the quadratic equation has 2 real solutions.

(b) If the discrimant is = 0, the quadratic equation has 1 real solution.

(c) If b^2-4ac is < 0, the quadratic equation has 0 real solution, therefore it has 2 imaginary solutions.

The square root's input (i.e., its contents), which is the phrase b^2 -  4ac, is known as the "discriminant" because using its value, you may "discriminate" between (i.e., be able to distinguish between) the different solution types.

To determine how many possible solutions a quadratic equation has, utilize the discriminant formula.

(a) If the discrimant is > 0, the quadratic equation has 2 real solutions.

Example

x^2 - 5x + 2 = 0

where a = 1, b = -5, c= 2

D=b^2 - 4ac = (-5)^2 - 4 ×1 × 2 = 17

∴ It has two real solutions.

(b) If the discrimant is = 0, the quadratic equation has 1 real solution.

Example

x^2 + 2x + 1 = 0

where a = 1, b = 2, c= 1

D=b^2 - 4ac = (2)^2 - 4 ×1 × 1 = 0

∴ It has one real solution.

(c) If b^2-4ac is < 0, the quadratic equation has 0 real solution, therefore it has 2 imaginary solutions.

Example

3x^2 + 2x + 1 = 0
