1 answer:
Rainbow [258]3 years ago
4 0

Answer:

f^-1 (x) =  1+ln( (x-3)/2)

Step-by-step explanation:

hello :

let f(x) = y  so : y = 2e^(x-1) +3

calculate x :  e^(x-1) = (y-3)/2

for : y-3 > 0 :  x-1 = ln( (y-3)/2)    so : x= 1+ln( (y-3)/2)

If(x)= 2e^(x-1) +3 , what is f^-1 (x) =  1+ln( (x-3)/2)

\frac{x^{2}+x-4}{x^{2}+3x+2}

Micah did not explain the last step correctly.  You cannot cross out a term from the numerator and denominator unless it is a factor.  In other words, x² needed to be multiplied and not added in order to cross it out.

I I need the answer as soon as possible please!! (Worth 15 points!)
NARA [144]

Answer:

70

Step-by-step explanation: Lets say x is the integer

5,600/x=80 is the same as

5,600÷x=80.

You should then rewrite it as 5,600÷80=x

Now simplify.

x=70

Remove parentheses and simplify 7a+6b-4 (3a-3b)
Varvara68 [4.7K]
Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion

7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)

7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer

Which function will have a y-intercept at –1 and an amplitude of 2?
Angelina_Jolie [31]

Answer:

Options B and D.

Step-by-step explanation:

The general form of sine function

h(x)=A\sin (Bx+C)+D

where, |A| is amplitude, \frac{2\pi}{B} is period, \frac{-C}{B} is phase shift and D is y-intercept.

The general form of cosine function

h(x)=A\cos (Bx+C)+D

where, |A| is amplitude, \frac{2\pi}{B} is period, \frac{-C}{B} is phase shift and D is y-intercept.

In function, f(x)=-\sin x-1

Amplitude : |A|=1

y-intercept : -1

In function, f(x)=-2\sin x-1

Amplitude : |A|=2

y-intercept : -1

In function, f(x)=-\cos x

Amplitude : |A|=1

y-intercept : 0

In function, f(x)=-2\cos x-1

Amplitude : |A|=2

y-intercept : -1

Therefore, the correct options are B and D.

Using words, explain all steps of dimensional analysis when converting 6.7 hectometers to meters.
9966 [12]
<h2>6.7 hectometers is equal to "670 meters".</h2>

Step-by-step explanation:

We have,

6.7 hectometers

To convert 6.7 hectometers to meters.

We know that,

1 hectometer = 100 meters

⇒ 1 hm = 100 m

∴ 6.7 hectometers

= 6.7 × 100 meters

= 670 meters

∴ 6.7 hectometers (hm) = 670 meters (m)

Thus, 6.7 hectometers is equal to "670 meters".
