The length of a rectangle is 5in longer than its width. If the perimeter of the rectangle is 46in, find its area

Crank

width = x
length = x+5

2x + 2(x+5) = 46
2x + 2x + 10 = 46
4x = 46 - 10
4x = 36
x = 36/4 
x = 9 in ← width

length = x+5 = 9 + 5 = 14 in

Area = 9 * 14 = 126 in²

A portion of the Quadratic Formula proof is shown. Fill in the missing statement. x equals b plus or minus the square root of b

liraira [26]

Answer: $x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

Step-by-step explanation:

When you subtract b/2a from both sides, you end up with the Quadratic Formula.

1) State the amplitude, period, phase shift, vertical shift and graph

bogdanovich [222]

Answer:

See answers and explanations below (along with a visual graph)

Step-by-step explanation:

For the function $y=acos(b(x+c))+d$ :

Amplitude: $|a|$

Period: $\frac{2\pi}{|b|}$

Phase shift: $\frac{-c}{b}$

Vertical shift: $d$

Therefore, for $y=2cos(\frac{2}{3}(\theta+\pi))-1$ :

Amplitude: $|a|=|2|=2$ , which is 2 units above and below the midline (see d)

Period: $\frac{2\pi}{|b|}=\frac{2\pi}{|\frac{2}{3}|}=\frac{2\pi}{\frac{2}{3}}=3\pi$ , so the cycle will repeat every 3π units

Phase shift: $\frac{-c}{b}=\frac{-\frac{2\pi}{3} }{\frac{2}{3} }=-\pi$ , or π units to the left

Vertical shift: $d=-1$ , or 1 unit down
