Hey!

The nth term for your sequence is -2!

18 - 2 = 16

16 - 2 =14

And so on! (the nth term of a sequence is basically the differences between the different terms!)

Select the expression that has a value of 96.45

leonid [27]

Given:

Number is 96.45.

To find:

The expression that has a value of 96.45.

Solution:

In option a,

$0.9645\times 10^2=0.9645\times 100$

$0.9645\times 10^2=96.45$

In option b,

$9.645\div 10^1=\dfrac{9.645}{10}$

$9.645\div 10^1=0.9645\neq 96.45$

In option c,

$964.5\times 10^3=964.5\times 1000$

$964.5\times 10^3=964500\neq 96.45$

In option d,

$9645\div 10^3=\dfrac{9645}{1000}$

$9645\div 10^3=9.645\neq 96.45$

Therefore, the correct option is a.

Find the value of x. Round to the nearest tenth.<br> PLEASE HELP ME!!

Mekhanik [1.2K]

Answer:

Step-by-step explanation:

Use the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have

$leg=x,\ leg=15.6cm:2=7.8cm,\ hypotenuse=8.8cm$

Substitute:

$x^2+7.8^2=8.8^2$

$x^2+60.84=77.44$ <em>subtract 60.84 from both sides</em>

$x^2=16.6\to x=\sqrt{16.6}\\\\x\approx4.1\ cm$
