Answer:

y = (5/9)(x -2)(x +6)

Step-by-step explanation:

When a polynomial has a zero (p, 0), it has a factor (x -p).

The given zeros mean the factored form of the equation will be ...

y = a(x -2)(x +6)

The given point will mean the value of 'a' will satisfy ...

(x, y) = (3, 5)

5 = a(3 -2)(3 +6) = 9a

a = 5/9 . . . . . . . . . . . . . . divide by the coefficient of 'a'

The factored equation is ...

y = (5/9)(x -2)(x +6)

Simplify the problem: Sin theta Sec Theta

kherson [118]

Answer:

$\tan \theta$

Step-by-step explanation:

We have to simplify the following expression as given by

$\sin \theta \times \sec \theta$

= $\frac{\sin \theta}{\cos \theta}$

= $\tan \theta$ ( Answer )

Because, we know that $\sec \theta =\frac{1}{\cos \theta}$ and $\tan \theta = \frac{\sin \theta}{\cos \theta}$

If we consider $\sin \theta = \frac{Perpendicular}{Hypotenuse}$ and $\sec \theta = \frac{Hypotenuse}{Base}$ ,

then $\sin \theta \times \sec \theta = \frac{Perpendicular}{Hypotenuse}\times \frac{Hypotenuse}{Base} = \frac{Perpendicular}{Base}= \tan \theta$

What is the answer to this equation 2/3x +7= 5

nadezda [96]

Answer:

x = -3

Step-by-step explanation:

$\frac{2}{3} x + 7 = 5\\\frac{2}{3} x = 5 - 7\\\frac{2}{3} x = -2\\x = -2 / \frac{2}{3}\\x = -2 * \frac{3}{2}\\x = -6/2\\x = -3$

What's the perimeter or how do you find it?

ziro4ka [17]

The perimeter of inside of the track is 536.44m

<h3>Perimeter of a circle and rectangle</h3>

The perimeter of a circle is also known as the circumference of the circle. The formula for calculating the circumference is expressed as:

C = 2πr

where

r is the radius

From the given diagram

r = 46/2 = 23m

C = 2(3.14)(23)
C = 144.44m

Find the perimeter of the rectangle

P = 2(l+w)

p = 2(46+150)
P = 2(196)
P =392m

The perimeter of the inside track = 144.44 + 392

The perimeter of the inside track = 536.44m

Hence the perimeter of inside of the track is 536.44m
