Answer:

Step-by-step explanation:

amplitude of oscillation a = 12 / 2 = 6 inches.

time period T = 2 s

b = angular frequency = 2π / T

= 2π / 2

= π

so putting the values in the equation

d = a cos ( b t )

d = 6 cos ( π t )

A road bike has a wheel diameter of 622 mm. What is the circumference of the wheel? Use 3.14
Vlad1618 [11]

The formula for finding the circumference of a circle is c=\pi *d (where d is the diameter). So, simply plugging in 622 mm for <em>d </em>and 3.14 for pi, we find that c = 622 * 3.14 = 1953.08 mm.

A coin weighs 5/6 ounces. Ann picked up 3 of these coins.
JulsSmile [24]
How I’d do it:
5/6 three times makes 15/6. Made into a mixed fraction is 2 3/6, which in its simplest form is 2 1/2.
When converted to ounces, assuming that 6/6 is one complete ounce, then you get 2.5 ounces.
The total weight she picked up is 2.5 ounces.

Answer:

you will add $1.53 to every bracelet you make

Step-by-step explanation:

figure out what 85 percent of 1.80 is and then add that to 1.80 for the total price

85% x 1.8 = 1.53 (markup ammount)

1.80 + 1.53 = 3.33 (total cost)

Find the slope intercept form of the equation of the line through the points(2,-4) parallel to the line 8x+2y+2=0
Margarita [4]

Answer:

y = -4x + 4

Step-by-step explanation:

8x+2y+2=0

turn that into slope intercept form:

y = -4x - 1

a parallel line has the same slope, but different y-intercept

y = -4x + b

put (2,-4) into the equation

-4 = -4(2) + b

you get b=4

final product:

y = -4x + 4
