Answer:

138 degrees

Step-by-step explanation:

Angle b and the 42 degree angle right next to it are supplementary angles. That means that 42+b=180

b=138

How many years will it take $39,450 to double at an interest rate of 3.2%, continuously compounded? *

taurus [48]

Years = natural log (total / principal) / rate
Years = ln (78,900 / 39,450) / .032
Years = ln (2) / .032
Years = 0.69314718056 / .032
Years = 21.6608493925 
And here's a calculator to check that answer:

The description below represents Function A and the table represents Function B:

ICE Princess25 [194]

The expression in A is equal to:
y = 8 + 3x
It can be observed that the equation is in the slope-intercept form which is equal to,
y = mx + b
where m is slope and b is intercept.

The slope and intercept therefore of this equation of the line are equal to 3 and 8, respectively.

For Part B:
The slope of the line can be calculated through the equation,
m = (y₂ - y₁) / (x₂ - x₁)
Substituting,
m = (5 - 2)/ (0 - -1) = 1.5

The intercept, b, is the value of y when x = 0. From the tabulation, y = 5 when x = 0. Thus, the intercept is equal to 5.

Comparing the slopes and intercepts of the equations, we can say that the slope of the second is only half that of the first and the intercept of the second is 3 less than that of the first equation.

7m − 5 − 13m = 25 what is m and explenation please :)

lesya [120]

The answer of m is -1 because if is -7 then the -13 and -7 will change reverse into positive so 7 + 5 + 13 = 25

Lea and her father arrived at the scenic overlook 15 minutes before noon and left 12 minutes after noon using am or pm write the

Aneli [31]

Answer:

They arrived at am and left at pm

Step-by-step explanation:

What do you need to find?

We need to find the time when Lea and her father arrived at the scenic overlook and the time when they left.

What do you need to find first?

First we need to find the exact minutes they arrived and left. Then we have to determine whether it was am or pm

Steps:

1. Noting the time they arrived

They arrived 15 minutes before noon

2. Determining whether it was am or pm

Noon is 12 pm by convention

Midnight is 12 am by convention

3. Calculating the minutes for exact time

Each hour has 60 minutes:

60 - 15 = 45

4. Determining the time(am or pm) after subtracting 15 minutes

which means they arrived at 11:45 am (am is used for time before 12 at noon)

5. They left 12 minutes after the noon:

Noon time is 12 pm

6. Adding 12 minutes to 12pm

The exact time becomes 12:12pm
