Answer: C

Step-by-step explanation:

1+2e^x+1=9

2e^x+1=9-1

e^x+1= 8/2

e^x+1 = 4

Here we can applicate the Ln:

ln e^x+1 = ln 4

Applicating the log property for exponent:

(x+1).ln e = ln 4

Ln e = 1, so:

x+1 = ln 4

x = ln 4-1

Question 3(Multiple Choice Worth 1 points)

maxonik [38]

Answer:

$g(x)=(x+3)^2$ best describes g(x)

Step-by-step explanation:

We are given an equation of graph $f(x)=x^2$

Rule : When the graph f(x) shifts left by c units . So, resultant graph is f(x+c)

Now we are given that The graph of $f(x) = x^2$ is shifted 3 units to the left to obtain the graph of g(x).

So, By using rule :

$f(x+3)=(x+3)^2$

So, $g(x)=(x+3)^2$

So, Option A is true

Hence $g(x)=(x+3)^2$ best describes g(x)

Of the 190 students in an elementary school, 57 students had perfect attendance during the second semester. What percent attenda

romanna [79]

Answer:

The percent attendance for that semester was 30%.

Step-by-step explanation:

In this problem, out of 190 students, only 57 students had perfect attendance. When a question says something like this, then it means that you are going to use division. You are going to divide 57 by 190.

57 ÷ 190 = 0.3

Now, multiply 0.3 by 100 to get the percentage.

0.3 * 100 = 30

So, the percentage of the perfect attendance is 30%.
