6(1) = 16<br> 6(n) = b(n − 1) + 1<br> Find the 2-term in the sequence.

Tresset [83]

Answer:

Step-by-step explanation:

Given

$b(1)=16\\ \\b(n)=b(n-1)+1$

Finding the second term of the sequence means to find $b(2).$ To find $b(2)$ substitute $n=2$ into the second expression:

$b(2)=b(2-1)+1\\ \\b(2)=b(1)+1\\ \\b(2)=16+1\\ \\b(2)=17$

Pleases someone explain

When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.

For example:

$\frac{1}{y^{-2}} =\frac{y^2}{1}$ or $y^2$

$2x^{-3}$ or $\frac{2^1x^{-3}}{1} =\frac{2}{x^3}$

$\frac{1}{x^{-5}} =x^5$

When a base with an exponent is divided by a base with an exponent, you subtract the exponents together. (But you can only combine the exponents when the bases are the same)

For example:

$\frac{x^2}{y}$ (can't combine because they have different bases of y and x)

$\frac{x^5}{x^3} =x^{(5-3)}=x^2$

$\frac{2^2}{2} =2^{(2-1)}=2^1 = 2$

When you multiply an exponent directly to a base with an exponent, you multiply the exponents together.

For example:

$(x^2)^3=x^{(2*3)}=x^6$

$(y^2)^{10}=y^{(2*10)}=y^{20}$

$\frac{2e^0}{(e^{-3})^2}$ First multiply the exponents together in the denominator

$\frac{2e^0}{e^{(-3*2)}}= \frac{2e^0}{e^{-6}}$ Now subtract the exponents together

$2e^{(0-(-6))}$ (two negative signs cancel each other out and become positive)

$2e^{(0+6)}$

$2e^6$

Find the area of the circle

motikmotik

The formula is $\pi$ r², and to find r, or radius, you divide the diameter by 2. Your radius is 12.5, so you just plug that into your formula, and you have pi(12.5)², and simplify that to pi(156.25) and then your answer is <span>490.873852123. You probably want to round to the nearest hundredth, I don't know if you have specific directions, but if so your final answer would be 490.87.</span>

Write an equation of a line in slope-intercept form with the given slope and y-intercept.

arsen [322]

Answer:

y=-2x+7

Step-by-step explanation:

The formula for this is y=mx+b

the m is the slope, and the b is the intercept, just plug them both in to make it work.
