what is the general equation of cosine function with a amplitude of 3 a period of 4pi and a horizontal shift of - pi
kicyunya [14]
The general form of such an equation will be
f(x)=A\cos\left(\dfrac{2\pi(x-B)}{C} \right)+D
where
  A = amplitude (3)
  B = horizontal shift to the right (-π)
  C = period (4π)
  D = vertical offset (0)

Your equation will be ...
f(x)=3\cos\left(\dfrac{x+\pi}{2}\right)

What is the answer to this equation
julia-pushkina [17]

Answer:

x = - \frac{494}{3} = - 164\frac{2}{3}

Step-by-step explanation:

75 + \frac{3}{8} x = 13\frac{1}{4}\\\\75 + \frac{3}{8} x = \frac{53}{4}\\\\\frac{3}{8}x = \frac{53}{ 4} - 75\\\\\frac{3}{8}x = \frac{53-300}{4}\\\\\frac{3}{8}x = - \frac{247}{4}\\\\x = -\frac{247 \times 8}{4 \times 3} \\\\x = -\frac{494}{3}

Can you help me!
MariettaO [177]

Hi,

4a - 11 = 2a + 3

4a - 11 + 11 = 2a + 3 + 11

4a = 2a +14

4a - 2a = 2a - 2a + 14

2a = 14

2a / 2 = 14 / 2

a = 7

3z + 12 = 15

3z + 12 - 12 = 15 - 12

3z = 3

3z / 3 = 3 / 3

z = 1

2 - 6b = 20

2 - 2 - 6b = 20 - 2

- 6b = 18

6b = - 18

6b / 6 = -18 / 6

b = -3

3y - 5 = 27 - y

3y - 5 + 5 = 27 - y + 5

3y = - y +32

3y + y = - y + y +32

4y = 32

4y / 4 = 32 / 4

y = 8

Consider the point.
aalyn [17]

Answer:

L = 8.366

Step-by-step explanation:

Given

A(0,0,0)

H(3,5,6)

we can apply the equation

L = √((xH-xA)²+(yH-yA)²+(zH-zA)²)

where L is the length of the diagonal of the box

then

L = √((3-0)²+(5-0)²+(6-0)²)

⇒   L = √(9+25+36) = √70

⇒   L = 8.366

We can see the box in the pic shown.
