Y = a sin b x
amplitude = a
period = 2π /b.

<span>y = 6 sin x
a = 6
b = 1
</span>
a, the amplitude, represents the highest point a graph reaches;
a = 6

The period represents the length of a cycle-

the period = 2π /b = 2π/1 = 2π

Answer:

Step-by-step explanation:

To solve this problem, we can make an equation using the values provided to us. The equation is shown below:

$350 + 32.50x = 1,500$

The first step is to subtract 350 from 1,500.

$32.50x=1,500-350$

$32.50x=1,150$

The last step is to divide 1,150 by 32.50 to get <em>x</em> by itself.

$x=\frac{1,150}{32.50}$

$x=35.38$

Kellen can have 35 people at the shower.

Solve by factoring 2x^3-9x^2+10x=0 with full steps

Strike441 [17]

X(2x²-9x+10)=x(2x-5)(x-2)=0.
x=0 is one solution.
2x-5=0 and x-2=0 give us the solutions x=5/2 and x=2.
So x=0, 2 or 5/2.

vodomira [7]

F(x)=8
3x+2=8
-2 both sides
3x=6
Divide 3 both sides
X=6/3
X=2
