Answer:

-2

Step-by-step explanation:

Notice that 1/e^2 = e^(-2), by power rules.

Now ln(e^x)=x.

So ln(1/e^2) = ln(e^(-2))=-2

3 nd 4

Step-by-step explanation:

hope this helps

B)

here,

A to B = 62

C To B = 11

A to C = ?

now,

so, 62 - 11 = 51

therefore a to C Is 51 cm

plz mark me brainliest ok

plz follow me

A)

Here,

A to B = 13

A to C = 26

total = ?

now,

A to B + A to C

13 + 26 = 39

Therefore,

total number is 39

Answer:

a) 45 minutes

b) 100 km/hr

Step-by-step explanation:

a) It is the length of the horizontal line in the graph. It extends from 14:45 to 15:30 and that is 45 minutes.

b) Andy travels 50 km in 30 minutes (=0.5 hr), that's 50/0.5 = 100 km/hr.

As per linear equation, Andy stayed his sisters house for 45 minutes.

The average speed on his journey home is 100 km/hour.

"An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line."

As per the graph, Andy drove from his home to his sisters house.

Then he rested for a while there.

After that, he returned back to his home.

It is clear from the graph that, Andy stayed his sisters house

= (15:30 - 14:45) hours = 45 minutes

Again, from the graph, the distance between Andy and his sister's house is 50 k.m.

Andy return back to his home in

(16:00 - 15:30) hours

= 30 minutes

= 0.5 hours

Therefore, the average speed on his journey home is

[tex]= \frac{50}{0.5} km/hour\\= 100 km/hour[/tex]

Answer:

f(x)＝(x-3)*(x+5)*(x-2)*(x+2)

Answer:

Step-by-step explanation:

Given the scale conversion;

3 centimeter = 5 feet

x = 30 feet

Cross multiply

5x = 3 * 30

5x = 90

x = 90/5

x = 18cm

Hence the side length in cm is 18cm

Area of the square = L²

Area of the square = 18²

Area of the square = 324cm²

Hence the area of the scale drawing is 324cm²

Given:

The graph of a line.

To find:

The equation of line and values of m and b. Check whether it is proportional or linear.

Solution:

From the given graph it is clear that, the line passes through (0,4) and (2,0). So, the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-4=\dfrac{0-4}{2-0}(x-0)[/tex]

[tex]y-4=\dfrac{-4}{2}(x)[/tex]

[tex]y-4=-2x[/tex]

Adding 4 on both sides, we get

[tex]y=-2x+4[/tex]

On comparing this equation with slope intercept form, i.e., [tex]y=mx+b[/tex], we get

[tex]m=-2\text{ and }b=4[/tex]

All lines are linear. If a line passes through the origin then it is proportional.

From the given graph it is clear that the line is not passing through the origin, i.e., (0,0). So, it is linear not proportional.

Therefore, the value of m is -2 and the value of b is 4. The equation of line is [tex]y=-2x+4[/tex].  The line linear not proportional because it does not passing through the origin.
