Evaluate (1/4)^—2-(5^0x 2)x1^-1

This expression is awkward.  Your (1/4)^--2 should be written (1/4)^(-2).
Also, your x 2 should be written x^2 (the square of x).

But maybe that's not what you meant!

Your apparent use of "x" to indicate "multiply" makes things harder and more confusing.  Please use " * " ONLY to denote multiplication.  

Let's try again.  Here's what I think I see:

(1/4)^(-2)    -    1*2*1^(-1)                  and here is the evaluation:

16               -      2              =    32

Practice typing in expressions like these and then try to get some critique from your teacher regarding where you are correct and where you are not.

The diagonals of this rhombus are 8 and 16 units long. Their intersection creates four right angles, two 4-unit-long segments, a
Roman55 [17]

Answer:

64\ \text{sq. units}

Step-by-step explanation:

Area of a rhombus is the product of the length of the diagonals divided by two.

Length of one diagonal is 8 units and the other diagonal is 16 units

Area is given by

A=\dfrac{8\times 16}{2}\\\Rightarrow A=64\ \text{sq. units}

The area of the rhombus is 64\ \text{sq. units}

Another approach is the diagonals have created 4 triangles where the base and is height is either 4 units long or 8 units long so the area of the rhombus would be the area of the 4 triangles.

A=4\times \dfrac{1}{2}\times 4\times 8\\\Rightarrow A=64\ \text{sq. units}

Which of the following is not a promotional tactic used by a seller?
Leviafan [203]

Answer:

we conclude that the 'bait and switch' technique is not a promotional tactic used by a seller.

Hence, 'a' is the correct option.

Step-by-step explanation:

From the given options, the 'bait and switch' technique is not a promotional tactic used by a seller.

'Bait and switch' is a deceptive sale practice using which the sells try to attract (bait) the customers by offering attractive prices on certain items, but when the customers tend to go to the shop to buy the items, they witness the unavailability of the goods, or find the prices go higher compared to what they had been offered.

Now, since the customers are already present at the shop, the sellers try to pressurize the customer so that they could buy something else.

Therefore, we conclude that the 'bait and switch' technique is not a promotional tactic used by a seller.

Hence, 'a' is the correct option.
