Find dy/dx.<br> x^2y+xy^2=6

AfilCa [17]

We are asked to evaluate dx/dy of the function x^2y+xy^2=6
we use implicit differentiation here:
2xy dx + 2xy dy = 0we can cancel 2xy from both terms in the left-hand side such that what is left is dx/dy = 0

What is the sum of the arithmetic series 16∑t-1 (6t-4)

Reil [10]

Answer:

Sum of an arithmetic sequence is given by the formula:

Sn = (a1 + an)*(n/2)

First term is 6(1) - 4 = 2

16th term is 6(16) - 4 = 92

(2+92)*(16/2) = 752

2. Use the same formula from above. (assuming the first term is when n = 1)

a1 = 2(1) - 3 = -1

a10 = 2(10) - 3 = 17

(-1+17)*(10/2) = 80

When 1,250 Superscript three-fourths is written in simplest radical form, which value remains under the radical?

Dvinal [7]

The value remains under the radical is 8 ⇒ last answer

Step-by-step explanation:

Let us revise how to write the exponent as a radical

$a^{\frac{m}{n}}$ can be written as $\sqrt[n]{a^{m}}$
To simplify the radical factorize the base "a" to its prime factors

Example:

$(54)^{\frac{2}{3}}=\sqrt[3]{(54)^{2}}$ ,
Factorize 54 into prime factors ⇒ 54 = 2 × 3 × 3 × 3 = $2(3)^{3}$
$\sqrt[3]{(54)^{2}}=\sqrt[3]{[2(3^{3}]^{2}}=\sqrt[3]{2^{2}*3^{6}}$
2² can not go out the radical because 2 is less than 3 not divisible by 3
$3^{6}$ can go out the radical because 6 is divisible by 3, then divide 6 by 3, so it will be 3² out the radical
$\sqrt[3]{(54)^{2}}=3^{2}\sqrt[3]{2^{2}}=9\sqrt[3]{4}$
