write the particular equation of this transformed sine graph. assume that the horizontal shift is 1 unit to the right. (hint: tr

Goryan [66]

We are given the graph of sine function.
First, we get the amplitude
A = [6 - (-2)] / 2
A = 4

Next, we determine the period and b
T = 4 - 0 = 4
b = 2π / T
b = π/2

The original sine function was
y = 4 sin πx/2

After the transformation, the equation now is
y = 4 sin [π(x+2)/2] + 2

HELP PLEASE! ONLY 5 MORE MINUTES! Look at the following shape below: Please find the PERIMETER of the following shape using the

Evgen [1.6K]

Answer:

The perimeter is $P=73.12\ cm$

Step-by-step explanation:

we know that

The perimeter of the figure is equal to the circumference of a semicircle

plus the perimeter of a square minus the diameter of the circle

$P=\pi r+4(b)-D$

we have

$r=8\ cm$

$b=16\ cm$

$D=16\ cm$

The diameter of the circle is equal to the length side of the square

substitute

$P=(3.14)(8)+4(16)-16$

$P=25.12+64-16$

$P=73.12\ cm$

Write each fraction as an expression with negative exponents.

Artemon [7]

The answer is w⁻²/v⁻².

v/w raised to the second power is (v/w)²

(v/w)² = v²/w²

Since xᵃ = 1/x⁻ᵃ, then v²/w² = 1/v⁻²w²

Since 1/xᵃ = x⁻ᵃ, then 1/v⁻²w² = w⁻²/v⁻²
