2^5= 32, the fifth root of_____=_____.
brilliants [131]

The fifth root of 32 is 2

In other words,

\sqrt[5]{32} = 2

It's similar to stating that 7^2 = 49 can be transformed into saying sqrt(49) = 7 where "sqrt" is shorthand for "square root"

The general rule is

x^n = b \ \  \longleftrightarrow \ \  \sqrt[n]{b} = x

Find the length of arc AB for each circle.
Eddi Din [679]

Answer:

see explanation

Step-by-step explanation:

The length of the arc is calculated as

AB = circumference of circle × fraction of circle

(11)

AB = 2πr × \frac{90}{360}

     = 2π × 7 × \frac{9}{36}

     = 14π × \frac{1}{4}

     = \frac{7}{2} π in

(12)

AB = 2πr × \frac{135}{360} ( r = 20 ÷ 2 = 10 )

      = 2π × 10 × \frac{3}{8}

      = 20π × \frac{3}{8}

      = \frac{60}{8} π

      = \frac{15}{2} π cm

The formula for the nth term of an arithmetic sequence can be found using the formula a Subscript n Baseline = a Subscript 1 Bas
Gnoma [55]

The equation of nth term will be written as for n as will be (\rm a_n - a₁ + d) / d. Then the correct option is D.

The missing options are attached to the picture given below.

<h3>What is a sequence?</h3>

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The formula for the nth term of an arithmetic sequence can be found using the formula given below.

\rm a_n = a_1 + (n-1)d

Then arrange the equation for n, we have

\begin{aligned} \rm a_n - a_1 & \rm = nd - d\\\\\rm a_n - a_1 + d & \rm =nd\\\\\rm n & \rm = \dfrac{a_n - a_1 + d}{d}  \end{aligned}

Then the correct option is D.

More about the sequence link is given below.

qaws [65]

The area of the triangle is 24 ft² while the area of the square is 64 ft²

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Area of triangle = (1/2) * base * height = 0.5 * 8 * 6 = 24 ft²

Area of square = 8 ft * 8 ft = 64 ft²

The area of the triangle is 24 ft² while the area of the square is 64 ft²
