Well 2+2=4 just think of 1+1+1+1

To help out Love2Read...there is no y intercept for the last one

The y intercept would occur where x = 0

But letting x =0  means a negative under the radical which can't result in a real number  !!!

Starting at t= 0.5 it takes until 1.5 to get back to its resting position (1/2 of a cycle) =  1 sec

Let's write

y = 3^(x - 1)       take the log of both sides

log y = log 3^(x - 1)

log y = (x - 1)log 3

log y / log 3 = x - 1

 [ log y / log 3 ] + 1   = x            swap x and y

[ log x / log 3 ]   + 1   = y   =   the inverse

Hello there bro let me help you out,

 I will do a problem for ou so you can figure it out!

As we can see we have f(x)=1/2 square root x-3

first thing that we need to do is find the zeros, which ill give you a hint, we have only 1 and it is displayed in the question.

that answer is the x-3 but the zero isnt -3 because we have to flip the sign which gives you 3 as your zero

now for the y intercept it isnt as simple

In fact I couldnt really find a Y intercept myself so I would have to say that there is either no Y intercept or that the intercept is 0.5

First one :  Good job  !!!!!

Second

x^3 - 10x^2 + 24x

y intercept  - easy - let x = 0    so  y = 0

zeroes...... factor

x ( x^2 - 10x + 24) = 0

x (x - 12) ( x + 2)  = 0

Set each factor to 0 and solve for x and we get that    x = 0 , x = 12  and x = 2

(2x - 3) ( 3x + 2)  =

2x *3x  - 3*3x + 2*2x- 3*2  =

6x^2 - 9x + 4x - 6  =

6x^2 - 5x - 6

Easiest to  use exponential properties and then convert to radical form

 (x^4y^7)^2/3  =

[ x^4 ]^(2/3)  * [ y^7 ]^(2/3)  =

x^(8/ 3)  * y^(14/3)  =

x^( 2 + 2/3)  *  y^(4 + 2/3)  =

x^2 * y^4  * x^(2/3) * y^(2/3)   =

x^2 * y^4  ∛ [ x^2 * y^2 ]

You were correct   !!!!

So sorry for the late reply! Thank you again for the help!

This number is simply powers of 3 numbers multiplied together as follows: 3^40 × 7^80 × 67^40

Merci i’ll try the next 10 problems on my own 

10(3+8k)+9(k+3)      =

10*3  + 10*8k  + 9k + 9*3  =

30 + 80k + 9k + 27  =

57 + 89k

De rien.....

without digging into it too deeply you look like you know what you're doing.

To be honest once out of college I never had to solve any analog circuits.

Merci bon monsieur

-4 ( 7r + 7)  =

-4* 7r    +     - 4 * 7   =

-28r    -  28

Yep, thanx !...I overlooked that....will edit.... 

17 + e^(7x) = 33     subtract 17 from both sides

e^(7x)  =  16           take the Ln of both sides

Ln e^(7x)  = Ln 16      and we can write

(7x) Ln e  = Ln 16         Ln e = 1.....so we  can ignore this

7x =  Ln 16         divide both sides by 7

x =  [ Ln 16 ]  / 7

AB = AC                                                        given

Angle 1 = Angle 2                                         given

Angle BAD is supplemental to Angle 1         supplementary pair

Angle CAD is supplemental to Angle 2         supplementary pair

Angle BAD  + Angle 1 = 180                         definition of supplemental

Angle CAD + Angle 2 = 180                          definition of supplemental

Angle BAD + Angle 1 = Angle CAD + Angle 2      substitution

Angle BAD = Angle CAD                                      subtraction property of equality

AD = AD                                                               reflexive property of equality

Triangle DAB congruent to Triangle DAC            SAS

Angle B  = Angle C                                            corresponding parts of congruent triangles are congruent

EP: Good Job!. A slight oversight. Plan 2 "accumulates 10% annual interest which compounds annually."

$10,000 x {1.10}^10 = $25,937.42.

You are correct, EP.....I didn't see that we had 5 people...!!!!

Hey Chris.....why would this NOT be  5 P 3 = 60

  which would include the outcomes quoted in the question?

Any 3 can finish 1st

And, after this, any 2 can finish second

So

3 x 2   =   6  possible finishing orders

4 (10)^(5x) = 200       divide both sides by 4

(10)^(5x) = 50          take the log of both sides

log 10^(5x) = log 50       and by a log property, we can write

(5x) log 10  =  log 50        log 10  = 1  ....so we can ignore this.....and we have

5x  =  log 50             divide both sides by 5

x =  [ log 50 ] / 5
