Answer with explanation:
A: Treasury Bond: In treasury bond interest is paid till that duration until the bond completely matures. When the period of bond gets over, Actual amount or Par Amount is Returned.
⇒A Saving Instrument.
B. C D
Compact Disc. A type of device that can store data, that is Nanotechnology is used to store more than 500 MB of data.
C: Saving Account
In saving Account, you can deposit and withdraw money at any time ,any day, with the evolution of new technology.
D: Checking Account
Same with the checking account,you can withdraw and deposit money any time on a day.
→Option A, C and D are , types of account , related with currency that is money, but option B, is term related to data.
Option B: →C D is not a Saving Instrument.
First term = T(1) is obtained by plugging n = 1 into the formula,
thus First term = 1^2 - 4 = 1 - 4

bearing in mind the standard form uses all integers, and the x-variable cannot have a negative coefficient.
Short Answer: y = 36°
Remark
What an interesting question!! The first thing you have to do is find out what the interior angle of a regular pentagon is. After you have done that, you can calculate y.
Method.
The exterior angles of a regular figure add up to 360°.
Step One
Find out the size of the exterior angles of a regular pentagon.
There are 5 such angles. They add up to 360°
5x = 360 Divide by 5
x = 360 / 5
x = 72°
Step Two
Find out the value of the interior angles of a pentagon.
Method
The interior and exterior angles add up to 180°
Exterior Angle + Interior Angle = 180°
Exterior angle = 72 degrees
72° + Interior Angle = 180° Subtract 72 from both sides.
Interior Angle = 180° - 72°
Interior Angle = 108°
Step Three
Solve for y.
There are 3 tiles each with an angle of 108° that are placed together. So y + 3 interior angles = 360°
y + 3*interior angles = 360°
y + 3*108 = 360
y + 324 = 360 Subtract 324 from both sides.
y = 360 - 324
y = 36°
