Find the zeros of the quadratic function: y= 6(7x + 9)(8x - 3).
A) (-9/7,0), (3/8,0)
B)(-7/9,0), (8/3,0)
C) (-3/8,0), (°/7,0)
D) (-8/3,0), (7/9,0)

Answers

Answer 1

Answer:

A) (-9/7,0), (3/8,0)

Step-by-step explanation:

Zeros of a quadratic function:

x for which y = 0.

In this question:

[tex]y = 6(7x + 9)(8x - 3)[/tex]

It's 0 if one of the factors is 0. 6 is never 0, now about the other to:

[tex]7x + 9 = 0[/tex]

[tex]7x = -9[/tex]

[tex]x = -\frac{9}{7}[/tex]

So (-9/7, 0) is a zero of the quadratic function.

The other is:

[tex]8x - 3 = 0[/tex]

[tex]8x = 3[/tex]

[tex]x = \frac{3}{8}[/tex]

(3/8,0) is the other zero.

Thus, the correct answer is given by option A.

for the perimeter of the shape.

Step-by-step explanation:

I cut out the extra square-ish pieces of the sides and found

that both are 17.2 for their perimeter. so 17.2×2= 34.4

then I found the perimeter of the sides of the rectangular shape and the sides were both 18.4ft. so 2(18.4+8.2)= 53.2.

so 53.2+34.4 = 87.6ft.

What is a Fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the first fraction be p = 2 7/9

Let the second fraction be q = 5/6

Now , A = p/q

On simplifying the equation , we get

A = 2 7/9 / 5/6

A = ( 25/9 ) / ( 5/6 )

A = ( 25/9 ) x ( 6/5 )

On simplifying , we get

A = 138/45

A = 46 / 15

Hence , the fraction is A = 46/15

Solve each equation for 0 ≤ θ 2π -2√2=-4sin 2θ

Answers

Answer:

Step-by-step explanation:

Begin by dividing both sides by -4 to get:

[tex]\frac{\sqrt{2} }{2}=sin2\theta[/tex] and then take the inverse sin of both sides to get

[tex]sin^{-1}(\frac{\sqrt{2} }{2})=2\theta[/tex] (the inverse sin undoes the sin on the right). Now we need to look on our unit circle to find the angles where [tex]sin(\frac{\sqrt{2} }{2})[/tex] is positive. There are 2 places. Sin is positive in both QI and QII. The angles are

[tex]\frac{\pi}{4},\frac{3\pi}{4}[/tex]. Therefore, our 2 equations are

[tex]\frac{\pi}{4}=2\theta[/tex]  and  [tex]\frac{3\pi}{4}=2\theta[/tex].  Solving the first equation:

[tex]\theta=\frac{\pi}{8}[/tex]

and the second equation:

Step-by-step explanation:

the answer is 0.2

The average of x and y is 03

How to determine the average?

The average of the three numbers is given as:

Average = 10

This means that:

(x + y + 24)/3 = 10

Multiply both sides by 3

x + y + 24 = 30

Subtract 24 from both sides

x + y = 6

Divide by 2

(x + y) = 3

Hence, the average of x and y is 03
