Answer:

Step-by-step explanation:

1). x² - 8x

To convert this expression into a perfect square trinomial,

x² - 2(4x) + 4² = (x - 2)²

Therefore , 4² = 16 should be added.

Option (4) is the answer.

2). x² + 2x = 3

x² + 2(1)(x) = 3

x² + 2(1)(x) + 1 = 3 + 1 [By adding 1 on both the sides]

(x + 1)² = 4

x + 1 = ±2

x = -3, -1

Option (1) is the answer.

3). 3x²- 18x = 21

x² - 6x = 7

x² - 2(3x) = 7

x² - 2(3x) + 3² = 7 + 3²

(x - 3)² = 7 + 9

(x - 3)² = 16

x - 3 = ±4

x = -1, 7

castortr0y [4]

An equation for water level in june for pensacola as a function of time (t) is f(t) = 5 cos pi/6 t + 7.

Which equation of cos show period amplitude ?

The equation given below show aplitude and period

$y = A cos bx + c$

where A = amplitude,

b = 2 pi/Period,

Period = 12 hrs,

c = midline,

x = t and y = f(t)

We have to find the amplitude

<h3>What is the formula for the amplitude?</h3>

$A = 1/2 (Xmax - Xmin)$

$12 - 2 / 2 = 10/2 = 5$

$b = 2 pi / 12 = pi/6$

$c = 1/2 (Xmax + Xmin)$

$12+2/2 = 7$

Therefore, the an equation for water level in june for pensacola as a function of time (t)

$f(t) = 5 cos pi/6 t + 7$
