Answer:

StartFraction 25 Over 9 EndFraction

Step-by-step explanation:

\bigg(  \huge{\frac{ {3}^{2}a ^{ - 2}  }{3 {a}^{ - 1} }} \bigg)^{k}  \\  \\  =  \bigg(  \huge{\frac{ 9a   }{3 {a}^{ 2} }} \bigg)^{k}  \\  \\  = \bigg(  \huge{\frac{ 3   }{ {a}}} \bigg)^{k}  \\  \\  = \bigg(  \huge{\frac{ 3   }{ {5}}} \bigg)^{ - 2}   \\  \\  = \bigg(  \huge{\frac{ 5   }{ {3}}} \bigg)^{ 2}  \\  \\  =   \huge{\frac{ 25   }{ {9}}}

An arithmetic sequence has this recursive formula:
horsena [70]

Answer:

\text{\bf{C.}}\quad a_n=4+(n-1)(-7)

Step-by-step explanation:

An arithmetic sequence that is described by the explicit formula ...

  a_n=a_1+(n-1)d

can also be described by the recursive formula ...

  \left \{\begin{array}{l}a_1=\text{(first term)}&a_n=a_{n-1}+d&\end{array}\right.

Matching parts of the formulas, we see that a1 = 4, d = -7. Putting these values into the explicit formula gives ...

a_n=4+(n-1)(-7)

A mother gives birth to a 9 pound baby. every 4 months, the baby gained 2 pounds. if x is the age of the baby in months, then y
chubhunter [2.5K]
For the equation of the line of the form y = mx + b, m is the slope of the line and b is the y-intercept which is the value of y when x is equal to zero. The slope is the rate of change of y per change in x. "y" would represent the dependent variable which is the weight of the baby while "x" represents the independent variable which is the number of months or the age of the baby in months. We calculate the slope as follows:

slope = (11 - 9) / ( 4 - 0) = 2/4 = 0.5
at x = 0, it is said that the weight of the baby is 9 lbs so the value of b would be 9.

The equation of the line would be y = 0.5x + 9

In the image, shape ABCD is similar to shape WXYZ. Find the measure of side ZW.
vladimir2022 [97]

Solution:

we are given that

In the image, shape ABCD is similar to shape WXYZ.

we have been asked to find the measure of side ZW.

As we know that when two shapes are similar then the ratios of their corresponding sides are equal.

So we can write

\frac{zw}{6}= \frac{18}{24}\\&#10;\\&#10;ZW=6*\frac{18}{24}\\&#10;\\&#10;ZW=\frac{18}{4}\\&#10;\\&#10;ZW=4.5\\

Hence ZW=4.5 Inches.
