The quadratic equation whose roots are -6 and -1 with leading coefficient 1 is [tex]x^{2} +7x+6=0[/tex].

Given that a Quadratic equation whose roots are -6 and -1 with leading coefficient is 1 and asked to find the equation of quadratic equation.

Quadratic equation:

The polynomial equations of degree two in one variable of form f(x) = a[tex]x^{2}[/tex] + bx + c = 0 and with a, b, c, ∈ R and a ≠0 are known as quadratic equations. It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" is for the absolute term of f(x).

For a quadratic equation if (a,b) are roots then,

(x-a)(x-b) is the quadratic equation having roots "a" and "b"

The equation with roots -6 and -1 is
⇒(x+6)(x+1)

⇒[tex]x^{2}[/tex]+7x+6

Answer:

angle 1 = 51

angle 2 = 39

Step-by-step explanation:

The sum of two angles is equal to 90° since they are complementary angles

angle 1 + angle 2 = 90° rewrite equation using given values

x + 38 + 3x = 90 add like terms

4x + 38 = 90 subtract 38 from both sides

4x = 52 divide both sides by 4

x = 13 now to find the measure of each angle replace x with 13

angle 1 = 51

angle 2 = 39

So 12 more than N would be 12 + N.

Answer:

b) 12 + n

Step-by-step explanation:

The statement is,

→ 12 more than a number.

Now equation will be,

→ 12 + n

≈ (or) n + 12

So, option (b) is correct.

The value of a based on the information is 4.

It should be noted that b = 5.5

It should be noted that e = 10

There are three alphabets in between them. This means the difference will be:

= (10 - 5.5)/3

= 1.5

Therefore, the value of a will be:

= 5.5 - 1.5

= 4

Step-by-step explanation:

The equation shows that the slope of the line is 3 and the y-intercept is 4 that is the line will pass through the point (0, 4)

The standard linear equation is expressed as y = mx + b where;

m is the slope

b is the y-intercept

Given the linear equation (y-1) = 3(x+3)

Expand

y-1 = 3x + 3

Answer: -18 ==> C

Step-by-step explanation:

x = −3 and y = −6

3x + 4y + 15=

3(-3) + 4(-6) + 15=

-9 + (-24) + 15 =

-9-24+15=

-(9+24)+15=

-33+15=

-(33-15)=-18 ==> C

Answer:

c) -18

Step-by-step explanation:

Given that,

→ x = -3

→ y = -6

Let's solve the problem,

→ 3x + 4y + 15

→ (3 × -3) + (4 × -6) + 15

→ -9 - 24 + 15 = -18

Thus, the solution is -18.

According to the formula speed = distance / time The rate in miles per hour is 4.54

If you know how far something has traveled and how long it took to get there, you can calculate its average speed. Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to calculate the units for speed.

Rachel jogs 20 feet in 3 seconds

then by the formula

speed = distance/time

speed = 20 feet / 3 seconds

speed = 6.666667 feet per hour

but this speed is in feet per seconds to convert the speed from feet per seconds to miles per hour we need to multiply by 0.681818,

speed = 6.66667*0.681818

speed = 4.5454 miles per hour

the graphic shows that the angle at A is split in half by the line AD (because the angles at both sides of the line are marked as equal, so the whole angle must be 2 times of one of these parts).

so, as CAD = 29°, CAB = 2×CAD = 2×29 = 58°

Step-by-step explanation:

that means that there is one scale factor for all sides of the triangles.

so,

2 × f = 14

f = 14/2 = 7

and to control, this has to work also for the other given side :

3 × 7 = 21

so, the scaling factor to get from E to F is 7.

The polynomial of 3rd degree whose zeros and degree are given as for zero of (-2), multiplicity 1 and for zero of (3), multiplicity 2 is [tex]f(x)=(x^{3}-10x^{2} -15x+18)[/tex]

As per the question statement, a 3rd degree polynomial has a zero of (-2), multiplicity 1 and another zero of (3), multiplicity 2.

We are required to determine the polynomial.

Since, (-2) is a zero of the polynomial, then [tex][x-(-2)]=(x+2)[/tex] will be a factor of the polynomial. And since for zero of (-2), multiplicity is 1, this means that the factor of (x + 2) is only multiplied once.

Similarly, as (3) is another zero of the polynomial, then [tex](x-3)[/tex] will be a factor of the polynomial. And since for zero of (3), multiplicity is 2, this means that the factor of (x - 3) will be multiplied twice, i.e., [tex](x-3)^{2}[/tex].

Therefore, our function, say, f(x) will be [tex](x+2)(x-3)^2[/tex]

[tex]or, f(x) = (x+2)(x-3)^2\\or, f(x) = (x + 2)(x^{2} +9-12x)\\or,f(x) =x^{3}+9x-12x^{2} +2x^{2} +18-24x\\ or, f(x)=x^{3}+(2x^{2}-12x^{2})+(9x-24x)+18\\or, f(x)=(x^{3}-10x^{2} -15x+18)[/tex]

Hence, our required polynomial is [tex]f(x)=(x^{3}-10x^{2} -15x+18)[/tex]
