Compare the numbers with<br> &gt;, &lt;, =<br> - 3.5 ____ 2.8<br> 7.4 ____ - 9
labwork [276]

Answer:

-3.5 <u>   <   </u> 2.8

7.4 <u>   >   </u> -9

Step-by-step explanation:

If you have a negative number and a positive number the <em>positive number is always greater.</em>

When you have a negative number and another negative, <em>the smallest number is greater. </em>

For example: -2.5 <u>       </u> -3.7

-2.5 is greater than -3.7 because it is <em>less</em> negative.

-2.5 <u>   >   </u> -3.7

When you have a positive number and a positive number, <em>the biggest number is greater.</em>

For example: 8.3 <u>       </u> 4.2

8.3 is greater than 4.2 because it is a <em>bigger number</em>.

8.3 <u>   >   </u> 4.2

Use the ratio test to determine whether the series is convergent or divergent.
Kitty [74]

Answer:

Divergent

Step-by-step explanation:

Given series has general term as

\frac{2^n}{n^2}

n+1 th term =\frac{2^(n+1)}{(n+1)^2}

WE have to check whether this series converges or diverges

Let us use ratio test

Ratio of n+1 th term to nth term

=\frac{2n^2}{(n+1)^2} =\frac{2}{(1+\frac{1}{n} }^2

by dividing numerator and denominator by n square

Take limits as n tends to infinity

The ratio tends to 2

Since ratio >2, the series diverges

Well first you have to figure out what x is, so that would be 200+75 and you would get 275, with that i could say i have $275, i owed becky $75 from last week so i gave her $75. with that you would have $200 after subtracting or giving the money to becky.

The function h is defined by h(x) =<br> 6+ x<br> -5+ 3x<br> Find h(5a).
almond37 [142]

Answer:

(6+5a)/ (-5 +15a)

Step-by-step explanation:

h(x) = (6+x) / (-5+3x)

Let x = 5a

h(5a) =(6+5a) / (-5+3*5a)

        = (6+5a)/ (-5 +15a)
