ALG TWO HELP ASAP?
Alexxx [7]

Answer:

Therefore the period of the sinusoidal wave = 3.14.

The amplitude of the function = 2.

Step-by-step explanation:

The period of a sinusiodal wave is given by the length of x axis which covers one full cycle of the wave, which one positive half-cycle and one negative half cycle.

From the graph we can see  that one of the cycles starts at -3.14 / 4 and ends at 3.14 \times 3/4.

Therefore we can sutract the start point value from the end point value to get the period

Therefore period  = (3.14 \times 3/4) - (-3.14 / 4) = (3.14 \times 3/4) + (3.14 / 4) = 3.14

Therefore the period of the sinusoidal wave = 3.14.

The amplitude of the function = 2.

Write an equation of the circle with center (6, 2) and radius 4.
luda_lava [24]

Answer:

(x-6)^2+(y-2)^2=16.

Step-by-step explanation:

(x-h)^2+(y-k)^2=r^2 is the equation for a circle with center (h,k) and radius r.

You are given center (6,2) and radius 4.

So we will replace h with 6 and k with 2 and r with 4.

This gives us:

(x-6)^2+(y-2)^2=4^2

Simplify:

(x-6)^2+(y-2)^2=16.

A rectangular vegetable garden will have a width that is 4 feet less than the length, and an area of 140 square feet. If x repre
UNO [17]

Answer:

The length of the garden=14 feet

Step-by-step explanation:

<em>Step 1: Determine the dimensions of the garden</em>

length of the garden=x feet

width of the garden=(x-4) feet

<em>Step 2: Determine the area of the garden</em>

Area of the garden=length×width

where;

area=140

length=x

width=x-4

replacing'

x(x-4)=140

x²-4x-140=0, solve the quadratic equation;

x={-b±√(b²-4ac)}/2a

x={4±√4²-4×1×-140}/2×1

x={4±√(16+560)}/2

x={4±√576}/2

x=(4±24)/2

x=(4+24)/2=14, or (4-24)/2=-10, take x=14

The length=14 feet, width=(14-4)=10 feet

The length of the garden=14 feet
