Answer:

$x=\frac{ln(\frac{19}{7}) }{2}$

Step-by-step explanation:

7*e^2x + 10 = 29

Subtract 10 to both side.

7*e^2x = 19

Divide 7 to both side.

e^2x = 19/7

Inverse e with ln.

ln(19/7) = 2x

Divide 2 to both side.

$x=\frac{ln(\frac{19}{7}) }{2}$

Find the fraction of stundents enrolled in each language

blondinia [14]

Fraction of students enrolled in Chinese = $\frac{51}{126}$

Fraction of students enrolled in French = $\frac{33}{126}$

Fraction of students enrolled in Spanish = $\frac{42}{126}$

Solution:

Total number of students = 51 + 33 + 42

= 126

Number of students enrolled in Chinese = 51

Fraction of students enrolled in Chinese

$$=\frac{\text{Number of students enrolled in Chinese}}{\text{Total number of students}}$

$$=\frac{51}{126}$

Fraction of students enrolled in Chinese = $\frac{51}{126}$

Number of students enrolled in French = 33

Fraction of students enrolled in French

$$=\frac{\text{Number of students enrolled in French}}{\text{Total number of students}}$

$$=\frac{33}{126}$

Fraction of students enrolled in French = $\frac{33}{126}$

Number of students enrolled in Spanish = 42

Fraction of students enrolled in Spanish

$$=\frac{\text{Number of students enrolled in Spanish}}{\text{Total number of students}}$

$$=\frac{42}{126}$

Fraction of students enrolled in Spanish = $\frac{42}{126}$

Please help I need workings

Aleonysh [2.5K]

So first thing is find the number of small boxes. Find 1% of 120, 1.2. Multiply 1.2 by 35, it’s 42.
Next find what the percent that 2/5 is. Divide two by five, it’s .4 or 40%. We already know one percent is 1.2 so multiply 1.2 by 40, 48.
Add this two.
42+48=90.
120-90=30

Small boxes:42
Medium boxes: 48
Large:30
42*6=252
48*10=480
15*30=450
1182 eggs total.

The graph of the piecewise function f(x) is shown what is the domain of f(x)

Rom4ik [11]

The domain of a function is where we have a value for x.

Since that's the case the domain of f(x) = {x e R / 1 ≤ x < 5}

We see that we have a value for x = 1 cuz we have a filled circle, but we don't have a value for x = 5, look at the unfilled circle

So, our x can vary between 1 and 5, but can't be 5.
