What are the answers and why?

Answers

Answer:

$\boxed{\text{(v) and (viii)}}$

Step-by-step explanation:

The three step test for continuity states that a function ƒ(x) is continuous at a point x = a if three conditions are satisfied:

f(a) is defined.
The limit of ƒ(x) as x approaches a exists.
The limit of ƒ(x) as x approaches a is equal to f(a).

(i) Left-hand limit = right-hand limit.

Pass. The limit from either side is 8.

(ii) Left-hand limit = limit.

Pass. If the limits from either direction exist, the limit exists.

(iii) Limit as x ⟶ ∞ is not part of the three-step test.

(iv) Limit as x ⟶ 1 exists. Pass.

(v) f(1) is defined.

FAIL. f(1) is not defined.

(vi) Limit as x ⟶ ∞ is not part of the three-step test.

(vii) Passing the three-step test is not a step in the test.

(viii) The limit as x ⟶ 1 does not equal f(1).

FAIL. f(1) is undefined.

The steps in the three-step test for which the function fails are $\boxed{\textbf{(v) and (viii)}}$ .

A dime weighs 50% as much as a nickel does what is the weight of a dime?

Answers

It's weight would be: x*150 / 100

Where, x= weight of nickel

Final answer:

A nickel weighs 5 grams. As a dime is said to weigh 50% as much as a nickel, we calculate 50% of 5 to find the weight of the dime, which gives us 2.5 grams.

Explanation:

The subject of this question is in the context of Mathematics, more specifically proportional relationships. The weight of a nickel is 5 grams. As mentioned, a dime weighs 50% less than a nickel. So to find the weight of the dime, we calculate 50% of 5 grams.

First, to find 50%, we need to divide by 100 and then multiply by 50. That is: (5 / 100) * 50 = 2.5 .

So, a dime weighs 2.5 grams. Always remember, weight measurements can have slight variations depending upon measurement techniques and tools used. For instance, if you place a coin on a standard electronic balance, you may obtain a weight of 2.5 g with a nominal uncertainty in the measurement of ± 0.01 gram. However, in a general sense for our calculation with given data, the weight of a dime is indeed 2.5 grams.

Answer:

28:15

3:13

Step-by-step explanation:

The ratios 28:15 and 3:13 are in their simplest form, meaning that they cannot be simplified any further.

Meanwhile, the other 3 ratios are not in their simplest form and can still be simplified if they are divided by either 2 or 4.

I like this question. When we factorise this question the brackets have to be identical.
5 has to be square rooted to become √5. From, FOIL we know that the last digit is times by the other last digit to find the 5, as our brackets are identical this number is the same. The square root of 5.
This number is doubled in identical brackets to find the middle number. so it is 2√5. As there is a minus number there the brackets are: (x-√5)(x-√5). Multiplying this out gives us: x²-2√5 x+5. k=2√5 (or -2√5, depending on if the minus is counted or not)
