Answer: The next three terms =2.56, - 1.024 and 0.4096

Step-by-step explanation:

Common Ratio of a Geometric sequence, R is calculated as

=a2/a1 = -40/100=-0.4

or a3/a2=16/ -40 = -0.4

such that the next three terms are

5th term =  -6.4 x -0.4=2.56

6th term= 2.56 x -0.4 =-1.024

7TH term= -1.024 x -0.4=0.4096

Pls help it'd be appreciated​

Answer:

option A

Step-by-step explanation:

∠WPS +∠OPW  = 180   {straight line}

∠WPS +110 = 180

∠WPS = 180 - 110

∠WPS = 70°

∠RWQ + ∠QWT +∠TWU = 180   {straight line}

∠RWQ + 60 + 50 = 180

∠RWQ + 110 = 180

∠RWQ = 180 - 110

∠RWQ= 70°

∠PWU +  ∠USP + ∠ WPS = 180  {angle sum property of triangle}

∠PWU + 40 + 70 = 180

∠PWU + 110 = 180

∠PWU = 180 - 110  

∠PWU = 70°

Use two unit multipliers to convert 20 inches to miles
jarptica [38.1K]

Answer:

Step-by-step explanation:

I answered another one of your questions so I will not explain as much.  ther are 12 inches in a foot and then 5280 feet in a mile so that's 1 ft/ 12 in and 1 mi/ 5280 ft.  So  the math is 20 in * 1 ft/ 12 in * 1 mi/ 5280 ft = .000315 mi.  

In reference to the last one, do keep in mind "square" inches and whatnot mean you square things.  so 1 ft/ 12 in becomes 1 ft^2/ 144 in^2.  Just as a small heads up to what could be tricky.

<u>Answer:</u>

A. 8.2 x 10^6

<u>Step-by-step explanation:</u>

To get what 4.1x10^3 is equal to you move the decimal point to the right three times. This leaves you with 4,100. To get what 2.0x10^3 is equal to, you move the decimal point to the right three times. This leaves you with 2,000. 4,100 x 2,000 is 8,200,000. Then move the decimal to the left until it is behind the 8. In order to do this, you would have to move the decimal point 6 times. So the final answer is 8.2 x 10^6.

What is the length of BC ? Round to the nearest tenth.<br> 16 cm
serg [7]

Since Sin is equal to opposite over hypotenuse

so that's mean Sin(60°) = \frac{x}{16}

#I just rounddown from angle 65° to 60° as the number is not that much different.

and Sin(60°) is equal to \frac{\sqrt{3} }{2}

so we got Sin(60°) = \frac{\sqrt{3} }{2} = \frac{x}{16}

x = \frac{16\sqrt{3} }{2}

x ≈ 14

then we can answer C)14.5

the answer D) is not correct for sure because the opposite cannot be longer than hypotenuse in the Right Triangle form.
