Answer:

Estimate the value of pi =3.14

Step-by-step explanation:

The diameter of the circle base of a storage container 18.8m

The diameter of the circle 'd' = 2r

Given data  'd' = 2r = 18.8m

The circumference of the circle = 2πr

Given data of circumference of the circle = 59 m

given        2πr = 59

                2r(π) = 59

                18.8 π = 59 ( by using 2r =18.8)

                  π = 59/18.8

                   π  = 3.13829

                    π  = 3.14

<u>Conclusion</u>:-

Estimate the value of pi =3.14

michelle hong noticed that her gross pay per period increased by 2,800 when her employer changed from a bi weekly pay plan to a
mart [117]

Answer:

<em>Her annual salary is $62,400</em>

Step-by-step explanation:

Michelle Hong noticed that her gross pay per period increased by 2,800 when her employer changed from a bi weekly pay plan to a monthly pay plan.

Bi weekly is a check every 2 weeks, so she would get 26 checks per year.

Monthly would be 12 checks per year.

When she gets paid monthly her pay increased by $2,800 each check.

Let x be one bi-weekly paycheck.

The equation we get is:

12(x+2800) = 26x

Multiply the bracket by 12:

12x +33600 = 26x

Subtract 12x from both sides

33600 = 14x

Divide both sides by 14:

x = 33600/14

<em>x = 2400</em>

Her pay increased by 2800 each period:

2400 + 2800 = 5200 per check.

5200 x 12 months = 62400

<em>Her annual salary is $62,400</em>

A function is shown: f(x) = 36x2 − 1.
german

Answer:

The equivalent function: f(x)=(6x+1)(6x-1)

Step-by-step explanation:

The x-intercepts of the given function on the graph can be obtained by equating the function to zero.

This is because on the x-axis, the y-coordinate is zero.

36x^{2} -1=0\\36x^{2} =1\\x=\frac{1}{6},-\frac{1}{6}

The function that has the same x-intercepts on the graph from the given options is:

f(x)=(6x+1)(6x-1)

Alternate Method:

The answer can also be obtained by factorizing the question.
