Find the indicated quantities for y equals f (x )equals 3 x squared. ​(A) Simplify StartFraction f (3 plus Upper Delta x )minus
torisob [31]

Answer:

6x

Step-by-step explanation:

Given that a function f(x) is given as

y=f(x) = 3x^2

A) f(x+ \Delta x) = 3((x+ \Delta x)^2=3(x^2+2x \Delta x+\Delta x^2)\\f(x) = 3x^2\\f(x+ \Delta x) -f(x) = 6x  \Delta x +\Delta x^2

Now divide by delta x

\frac{f(x+ \Delta x) -f(x)}{\Delta x}\\=6x+\Delta x

B) When delta x tends to 0, this becomes

6x

(NOte: This is the derivative of f(x))

If product of two numbers=384HCF=8,2cm=?​
lions [1.4K]

Answer:

96 and 288

Step-by-step explanation:

So, we need to find 2 numbers such that their sum is 8 and they do not have common factor (Relatively prime). Both these numbers will be divisible by 48 but there would be no other common divisor (after dividing by 48).

Such order independent pairs are (1,7) and (3,5).

Difference between them would be (7–1)*48=6*48 and (5–3)*48=2*48 respectively.

The differences are 6*48=288 and 2*48=96.

We have found difference without finding numbers.

Ans.: 96 and 288

p.s.: The number pairs (again order neutral) would be (48, 336) and (144, 240)

Difference for 48 and 336 add up to 384, their HCF is 48. These two numbers match the conditions. Their difference is 288.

Difference of 144 and 240 add up to 384, their HFC is 48 (the numbers are 48*3 and 48*5, common factor is 48 and no other common factor for 3 and 5; 48 is HCF). The difference is 96.

There are 5 people, l, m, n, o and p. M is taller than only p and o is taller than p and m both. O is smaller than l and n both
Free_Kalibri [48]

The study of proper reasoning or excellent arguments is known as logic.  O is taller than two people, M and P.

<h3>What is Logic?</h3>

The study of proper reasoning or excellent arguments is known as logic. It is sometimes described narrowly as the study of deductively valid deductions or logical facts.

M is taller than only P → M > P

O is taller than P and M both → O > M&P

O is smaller than l and n both but not m. → I&N > O > M

N is not the tallest one. I >N

Now, if we sum up all the conditions then we can arrange the 5 people from tallest to shortest as,

I > N > O > M > P

Hence, O is taller than two people M and P.

vaieri [72.5K]
A perfect score on a test with 25 questions is 100.
 Each question is worth 4 points.
=> 25 * 4 points = 100 points.

Fred got a score of 80 on the tes.
We need to write a division sentence usingnegative numbers where the quotient represents the number of questions Fred answered incorrectly

=> 100 - 80 = 20 points.
=> 20 / 4 points = 5 questions
