Write a cosine function that has a midline of 2, an amplitude of 4 and a period of
8/3

Answers

Answer 1

Answer: f(x) = 4*cos(pi*(6/8)*x) + 2

Step-by-step explanation:

A generic cosine function is written as:

f(x) = A*cos(w*x + p) + M

where:

A = amplitude

w = angular frequency

p = phase

M = midline.

We know that:

the midline is 2, then  M = 2

the amplitude is 4, then A  = 4

There is no information about the phase, so p = 0.

And we know that the period is 8/3.

The period is written as T, and the relation between the period and the angular frequency is:

T = 2*pi/w

Then we have:

8/3 = 2*pi/w

w = (2*pi)*(3/8) = pi*(6/8)

where pi = 3.14

Then we have:

w =  pi*(6/8)

A = 4

M = 2

p = 0

Then the cosine function is:

f(x) = 4*cos(pi*(6/8)*x) + 2.

Are 12/102 and 18/153 equivalent ratios?

Answers

Answer:

there are 2 ways:

[tex]\frac{12}{102}[/tex] ?= [tex]\frac{18}{153}[/tex]

1) try to simplify

[tex]\frac{12}{102}[/tex] (divide the numerator and denominator by 6) ?= [tex]\frac{18}{153}[/tex] (divide the numerator and denominator by 9)

2/17 = 2/17 so yes they are equivalent

2) use cross products

102x18 ?= 12x153

 1836 = 1836 so yes they are equivalent

Ed bus a box of eggs costing £2.30, two packs of bacon for £2.60 each and two tins of baked beans. He pays with a £10 note gets 80p change how much did the tin of beans cost?

Answers

Answer:

£0.85 for each

£1.70 for both

Step-by-step explanation:

Variable x = cost of baked beans

2.30 + 2(2.60) + 2x = 10 - 0.80

Use PEMDAS

2.30 + 5.20 + 2x = 10 - 0.80

7.50 + 2x = 9.20

Subtract both sides by 7.50

2x = 1.70

Divide both sides by 2 to isolate the variable

x = 0.85

Let's check our work by plugging this into our original equation

2.30 + 2(2.60) + 2(0.85) = 10 - 0.80

2.30 + 5.20 + 1.70 = 10 - 0.80

7.50 + 1.70 = 9.20

9.20 = 9.20

Our number is correct
