Answer:

<em><u>y = d + a · cos(bx - c) ⇒ y = -4cos(4/3x)</u></em>

  • a = -4
  • b = 4/3
  • c = 0
  • d = 0

Amplitude = |a| = |-4| = 4

Period = \frac{2\pi }{b} =\frac{2\pi }{\frac{4}{3} } =2\pi *\frac{3}{4} =\frac{3}{2} \pi

There are 130 m&amp;m's in a bag. there are half as many green as red. the number of blue is equal to the number of red and gree
AleksandrR [38]
Let x = red
Let 0.5x = green
Let (x) + (0.5x) = 1.5x = blue
Let 0.5(1.5x) = 0.75x = yellow
Let 0.75x + 4 = brown

(x) + (0.5x) + (1.5x) + (0.75x) + (0.75 + 4) = 130
x + 0.5x+ 1.5x + 0.75x + 0.75 + 4 = 130
4.5x + 4 = 130
4.5x = 126
x = 28

Use this value to calculate the other required numbers.
red = 28
green = 0.5x = 0.5(28) = 14
blue = 1.5x = 1.5(28) = 42
yellow = 0.75x = 0.75(28) = 21
brown = 0.75x + 4 = 0.75(28) + 4 = 25

sophie was 28 years old when daughter Nichole was born. In how many years will Sophie be two years less than still times Nichole
Kamila [148]
It will take 6 years for that to happen. 

You can find this by setting Nichole's age as x and Sophie's age as x + 28 since she will always be 28 years older. 

Now we are looking for a time that Sophie's age is equal to 2 less than 6 times Nichole's age. So we can set up the below equation. 

6(x) - 2 = x + 28
6x - 2 = x + 28
5x - 2 = 28
5x = 30
x = 6

This let's us know that it needs to be when Nichole is 6, which is 6 years in the future.

The diameter of the circle above is 22 cm. What is the circumference of the circle? (Use = 3.14.)
postnew [5]

Answer:

69.08cm

Step-by-step explanation:

The formula for the circumference is

pi times diameter=circumference

Since we are using 3.14 and we know the diameter we can plug that in

3.14 times 22= circumference

69.08=circumference
