Write one sine and one cosine equation for each graph below.

pychu [463]

Answer:

Q13. y = sin(2x – π/2); y = - 2cos2x

Q14. y = 2sin2x -1; y = -2cos(2x – π/2) -1

Step-by-step explanation:

Question 13

(A) Sine function

y = a sin[b(x - h)] + k

y = a sin(bx - bh) + k; bh = phase shift

(1) Amp = 1; a = 1

(2) The graph is symmetrical about the x-axis. k = 0.

(3) Per = π. b = 2

(4) Phase shift = π/2.

2h =π/2

h = π/4

The equation is

y = sin[2(x – π/4)} or

y = sin(2x – π/2)

B. Cosine function

y = a cos[b(x - h)] + k

y = a cos(bx - bh) + k; bh = phase shift

(1) Amp = 1; a = 1

(2) The graph is symmetrical about the x-axis. k = 0.

(3) Per = π. b = 2

(4) Reflected across x-axis, y ⟶ -y

The equation is y = - 2cos2x

Question 14

(A) Sine function

(1) Amp = 2; a = 2

(2) Shifted down 1; k = -1

(3) Per = π; b = 2

(4) Phase shift = 0; h = 0

The equation is y = 2sin2x -1

(B) Cosine function

a = 2, b = -1; b = 2

Phase shift = π/2; h = π/4

The equation is

y = -2cos[2(x – π/4)] – 1 or

y = -2cos(2x – π/2) - 1

How do I get the answer to m+4=13/2

Kaylis [27]

M=13/2 - 4

$\frac{13}{2} - \frac{4}{1} = \frac{13-8}{2} = \frac{5}{2} =2.5$

BONUS: What is the standard form of the linear model for Matuba? Matuba: 312.4 308.6

Elodia [21]

Answer:

Step-by-step explanation: The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

Completing the Square: -b/(2a)

Step-by-step explanation:

Step 1: Define

x² - 8x + 15 = 0

Step 2: Solve for x

[Subtraction Property of Equality] Subtract 15 on both sides: x² - 8x = -15
Complete the Square [Addition Property of Equality]: x² - 8x + 16 = -15 + 16
[Complete the Square] Simplify: (x - 4)² = 1
[Equality Property] Square root both sides: x - 4 = ±1
[Addition Property of Equality] Add 4 on both sides: x = 4 ± 1
Evaluate: x = 3, 5
