Answer:

1650 a. C

Step-by-step explanation:

Square roots are mathematical expressions that arose when posing various geometric problems such as the diagonal length of a square. The Papyrus of Ahmes dated around 1650 a. C., which copies older texts, shows how the Egyptians extracted square roots.

Find H.C.F. and L.C.M. of x3-y3, x2-y2 and (x-y) ?

maks197457 [2]

Answer:

1) x³-y³ = (x-y)(x²-xy+y²)

2)x²-y² =(x-y)(x+y)

3)x-y = (x-y)

hcf = (x-y)

lcm = (x-y)(x²-xy+y²)(x+y)= (x³-y³)(x+y)

prisoha [69]

Answer:

Less than $12

Step-by-step explanation:

I changed everything into decimals to make it easier to solve:

1 2/5= 1.4

2 3/10= 2.3

1.4+2.3=3.7

2.99·3.7=11.063 (Round it to the nearest hundredth and you get 11.06)

Given that -6,-6 is on the graph of f x find the corresponding point for the function f(3/4x)

Liono4ka [1.6K]

Answer:

The corresponding point is <em>(-8, -6).</em>

Step-by-step explanation:

Given that

(-6,-6) lies on the graph of $f(x)$

A function is represented in the form:

$y = f(x)$

i.e. (-6,-6) means value of x = -6 is put and value y came out as -6.

$f(-6) = -6$

Now, we have to find the corresponding point on $f(\frac{3}{4}x)$ .

We know the value of $f(-6)$

Let us find the value of x where $\frac{3}{4}x$ becomes equal to -6

$\dfrac{3}{4}x=-6\\\Rightarrow 3x=-24\\ \Rightarrow x =-8$

So, let us put value of $x = -8$ in $f(\frac{3}{4}x)$ :

$f(\frac{3}{4}\times (-8))\\\Rightarrow f(3\times (-2))\\\Rightarrow f(-6) = -6$ (as per given statement)

So, the corresponding point is <em>(-8, -6).</em>

PLSSS HELP IF YOU TURLY KNOW THISS

Alexandra [31]

Hello there! :)

6^8*6^3

Here, we have the same base, so we add the powers:

6^11

Now, our expression looks like this:

6^11/6^5

Subtract the powers now that we divide:

6^6

So the missing exponent is 6. Hope it helps!

If you have any query, feel free to ask!
