\:  \:  \:  \:

=  {a}^{2}  \:  {b}^{2}  -  {b}^{2}   \: {c}^{2}

Step-by-step explanation:

(ab + bc)(ab - bc)

  • use <u>(</u><u> </u><u>a </u><u>+</u><u> </u><u>b </u><u>)</u><u> </u><u>(</u><u> </u><u>a </u><u>+</u><u> </u><u>b</u><u> </u><u>)</u><u> </u><u>=</u><u> </u><u>a²</u><u> </u><u>-</u><u> </u><u>b²</u><u> </u>to simply the product

(ab {)}^{2}  - (bc {)}^{2}

  • to raise a <u>product</u><u> </u><u>to </u><u>a</u><u> </u><u>power </u>,raise each factor to that power

=  {a}^{2}  {b}^{2}  -  {b}^{2}  {c}^{2}

What is 2 and negative three using integers​
Darina [25.2K]

If you mean "how to write the sum", the answer is

2+(-3)

The result of this sum is -1, because you start from 2 on the number line and take 3 steps to the left (negative integers mean going left, positive integers mean going right)

Find the length of the curve y = integral from 1 to x of sqrt(t^3-1)
Arlecino [84]
y=\displaystyle\int_1^x\sqrt{t^3-1}\,\mathrm dt

By the fundamental theorem of calculus,

\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\mathrm d}{\mathrm dx}\displaystyle\int_1^x\sqrt{t^3-1}\,\mathrm dt=\sqrt{x^3-1}

Now the arc length over an arbitrary interval (a,b) is

\displaystyle\int_a^b\sqrt{1+\left(\frac{\mathrm dy}{\mathrm dx}\right)^2}\,\mathrm dx=\int_a^b\sqrt{1+x^3-1}\,\mathrm dx=\int_a^bx^{3/2}\,\mathrm dx

But before we compute the integral, first we need to make sure the integrand exists over it. x^{3/2} is undefined if x, so we assume a\ge0 and for convenience that a. Then

\displaystyle\int_a^bx^{3/2}\,\mathrm dx=\frac25x^{5/2}\bigg|_{x=a}^{x=b}=\frac25\left(b^{5/2}-a^{5/2}\right)

Can you help me with math?
GaryK [48]

Answer:

n = 143

Step-by-step explanation:

To find the value of n, you multiply 13 by 10 because that is the inverse of dividing, and you get 130. Since there is a greater than sign, the answer is 143 because the value of n has to be greater than 130.
