The terms are (4.2x), (-3.9), (-5.1x), (6)

like terms are terms that represent the same variable.

-3.9 & 6 both do not represent any varibles, they are just numbers, so they are like terms

4.2x & -5.1x both represent (x) so they are like terms.

to collect like terms, you create a smaller equation, just for them.
so you equations are;
-3.9+6
&
4.2x-5.1x

note: you know to add the 6 as all positive numbers have a + infront, it is just not written.

-3.9+6=2.1
4.2x-5.1x=-1.1x

therefore your equation after collecting like terms is 2.1-1.1x.

Hope this helps :)

If $560 is invested at an interest rate of 9% per year and is compounded continuously, how much will the investment be worth in
koban [17]

Answer:

$878.25

Step-by-step explanation:

Continuously compounded interest is:

A = Pe^(rt)

where A is the final amount, P is the initial amount, r is the interest rate, and t is the number of compoundings.

Here, P = 560, r = 0.09, and t = 5.

A = 560e^(0.09×5)

A = 878.25

The following table presents the time taken to review articles that were submitted for publication to a particular journal durin
belka [17]

A) Variance = 10.24

B) Standard Deviation = 3.2

One of the measurements of dispersion is the standard deviation, which is exclusively used for quantitative data. It aids in determining if the data's mean is a suitable measurement to reflect the core value.

TIME         FREQUENCY(f)  MIDPOINT(x)    d    d²     fd              fd²

0 - 0.9         43                          0.45             -3     9     -129            387

1.0 - 1.9         17                           1.45              -2    4     -34                68

2.0 - 2.9       19                            2.45             -1     1       -19               19

3.0 - 3.9        18                            3.45             0     0       0                  0

4.0 - 4.9        14                            4.45              1      1        14               14

5.0 -5.9         16                            5.45              2     4        32             64                            

∑f = 127                                                              

∑fd = -136  

∑fd² = 552

d = \frac{x - 3.45}{1}

Standard Deviation = \sqrt \frac{fd^{2} }{N} - \sqrt \frac{(fd)^{2} }{N} * i

\sqrt \frac{552}{127} -\sqrt (\frac{-136}{127})^{2}   * 1

√4.35 - √1.15

Standard Deviation = 3.2

(SD)² = (3.2)² = 10.24

Variance = 10.24

Find the root<br><br> X^3-125=0
Firlakuza [10]

Steps to solve:

x^3 - 125 = 0

~Add 125 to both sides

x^3 = 125

~Take cube root of both sides

x = 5
