What is the rational number equivalent to 1.28?

Vera_Pavlovna [14]

Step-by-step explanation:

here's your solution

=> in first figure , base = 5.5, perpendicular =7.8

=> h^2 = 5.5^2 + 7.8^2

=> h^2 = 30.25 + 60.84

=>h^2 = 91.09

=> h = √91.09

=> h = 9.5

 Both figure are congruent

enc we will get a rectangle by add both 

hope it helps

Circle A was translated 3 units to the left and 4 units up to create Circle B. Which rule describes the translation that was app

kifflom [539]

Answer:

$B = (x - 3, y + 4)$

Step-by-step explanation:

Given

Represent the coordinates of circle A with (x,y)

Translation

Left = 3 units

Up = 4 units

Required

Determine the coordinates of B

When a point (x,y) is translated by h units left, the new point is: (x - h, y)

When a point (x,y) is translated by b units up, the new point is: (x, y + b)

So, when circle A is completely translated to B, the new points of B is:

$B = (x - h, y + b)$

In this case:

$h = 3\ and\ b = 4$

So:

$B = (x - 3, y + 4)$

Simplify the expression using properties of exponents. 25a^-5b^-8/5a^4b

ivanzaharov [21]

Answer: The simplification is $5*a^{-9}*b^{-9}$

Step-by-step explanation:

Here we need to use the property:

$\frac{a^n}{a^m} = a^{n - m}$

We have the expression:

$\frac{25*a^{-5}*b^{-8}}{5*a^{4}*b}$

We can separate it in parts with the same base, then we can rewrite this as:

$\frac{25*a^{-5}*b^{-8}}{5*a^{4}*b} = \frac{25}{5} \frac{a^{-5}}{a^4} \frac{b^{-8}}{b}$

Using the first property we can rewrite this as:

$\frac{25}{5} \frac{a^{-5}}{a^4} \frac{b^{-8}}{b} = 5*a^{-5 - 4}*b^{-8 - 1} = 5*a^{-9}*b^{-9}$
