Rewrite it in the form a^2 - b^2, where a = 7q^2 and b = 2

(7q^2)^2 - 2^2

Use the Difference of Squares; a^2 - b^2 = (a + b)(a - b)

<u>= (7q^2 + 2)(7q^2 - 2)</u>

At a museum you can see the four cable lines that are used to pull cable cars up and down a hill. Each cable travels at a speed
borishaifa [10]

Answer:

54.514 rev/min

Step-by-step explanation:

Data provided in the question:

Speed of the cable car = 12.65 miles per hour

Diameter of the rotating wheel, d = 6.5 feet

Now,

The speed of rotation of the wheel will be equal to the speed of the cable car

thus,

The speed of rotation of the wheel = 12.65 miles per hour

also,

1 miles = 5280 feets

1 hour = 60 minutes

Thus,

The speed of rotation of the wheel = \frac{12.65\times5280}{60}

= 1113.2 ft/ min

Circumference of the wheel = πd

= 6.5π feet

= 20.42 feet

Therefore,

The speed of rotation of the wheel in  revolutions per minute

=  1113.2 ÷ 20.42 rev/min

= 54.514 rev/min

The principal of Angelo carrera saving account is $9855 it earns 6% interest compounded quarterly for two quarter
malfutka [58]

Answer:

$ 297.87 interest

Step-by-step explanation:

Calculate the amount and the compound interest.

Amount = PNR Where P is Principal ; N is the no of Terms and R is the rate of interest

  Amount of 1 st quarter  = $ 9,855 x 6 % x \frac{1}{4} = $147.83

Compound interest  is $ 9,855 + 147.83= $ 10,002.83

Amount of 2 nd quarter ,  10,002.83 x 6% x \frac{1}{4} =  $150.04

Compound Interest is 10,002.83 + 150.04  =  $10,152.87 amount

                               10,152.87 - 9,855= $297.87 interest
