If m and n are the zeroes of the polynomial 6y 2 -7y – 2, find a polynomial whose zeroes are 1/m and 1/n
denis-greek [22]

Answer:

y^2-\frac{7}{2}y+3

Step-by-step explanation:

Given polynomial is,

6y² - 7y - 2

Fro the zeros of the given polynomial,

6y² - 7y - 2 = 0

6y² - 4y - 3y - 2 = 0

2y(3y - 2) - 1(3y - 2) = 0

(2y - 1)(3y - 2) = 0

(2y - 1) = 0

y = \frac{1}{2}

(3y - 2) = 0

y = \frac{2}{3}

Therefore, zeros of this polynomial are m = \frac{1}{2} and n = \frac{2}{3}

If a polynomial has zeros as \frac{1}{m} and \frac{1}{n} then the zeros will be \frac{3}{2} and 2.

Polynomial will be,

(y-\frac{3}{2})(y-2)

= y(y-2)-\frac{3}{2}(y-2)

= y^2-2y-\frac{3}{2}y+3

= y^2-\frac{7}{2}y+3

The velocity of an object in meters per second varies directly with time in seconds since the object was dropped, as represented
IrinaVladis [17]

It is given to us that the velocity of an object in meters per second varies directly with time in seconds since the object was dropped, as represented by the table (which is not given to us). The acceleration due to gravity is the constant of variation. Now, we know, from basic physics that the value of the acceleration due to gravity in the SI unit is 9.8 m/s^2. Therefore, the second option is the correct option.

How do you find the equation of the line in standard form that is perpendicular to the line y=3x+2 and passes through (-1, 5)
Novay_Z [31]
y=mx+b \perp y=3x+2 \\
\Downarrow \hbox{the product of the slopes is -1} \\
m \times 3=-1 \\
m=-\frac{1}{3} \\ y=-\frac{1}{3}x+b \\ \\
(-1,5) \\
x=-1 \\
y=5 \\ 
\Downarrow \\
5=-\frac{1}{3} \times (-1) + b \\
5=\frac{1}{3}+b \\
5-\frac{1}{3}=b \\
\frac{15}{3}-\frac{1}{3}=b \\
b=\frac{14}{3} \\
y=-\frac{1}{3}x+\frac{14}{3} \\ \\
y=-\frac{1}{3}x+\frac{14}{3} \\
\frac{1}{3}x+y=\frac{14}{3} \ \ \ |\times 3 \\
\boxed{x+3y=14}

Does anyone know the answer plz ?
Natalija [7]

Answer:

x = 5; y = 5

Step-by-step explanation:

One angle is a right angle, so its measure is 90 degrees.

One angle measures 45 degrees, so the unknown angle must also measure 45 degrees.

x and y are opposite two 45-degree angles, so x = y.

In a 45-45-90 triangle, the ratio of the lengths of the sides is

1 : 1 : sqrt(2)

We have

x : y : 5sqrt(2)

x/1 = 5sqrt(2)/sqrt(2)

x = 5

y = 5
