You may need to input the number only without the "degrees".
=============================================================
Explanation:
First we'll focus on triangle DEH. Ignore the other points and values.
We have the sides of EH = 32 and DH = 49. Let x be the measure of angle DHE, which is one of the pieces of angle DHG. We'll use the cosine rule to find x.
cos(angle) = adjacent/hypotenuse
cos(H) = EH/DH
cos(x) = 32/49
x = arccos(32/49)
x = 49.227195
The value is approximate and rounded to 6 decimal places. Make sure your calculator is in degree mode. Arccos is the same as inverse cosine.
We'll come back to this value later.
---------------------
Now focus on triangle HFG. Ignore the other points.
We have the sides of FG = 38 and GH = 43
Let y be the measure of angle FHG, which is the missing piece to form angle DHG. Based on how x and y are set up, we can say x+y = angle DHG.
To find y, we'll need the sine rule this time
sin(angle) = opposite/hypotenuse
sin(H) = FG/GH
sin(y) = 38/43
y = arcsin(38/43)
y = 62.094527 which is approximate to 6 decimal places
---------------------
The last step is to add the values of x and y we found earlier
angle DHG = (angle DHE) + (angle FHG)
angle DHG = (x) + (y)
angle DHG = (49.227195) + (62.094527)
angle DHG = 111.321722
angle DHG = 111 degrees after rounding to the nearest whole degree.
----------------------
If you wanted to do this all in one step, you could say:
arccos(32/49)+arcsin(38/43) = 111.3217 which rounds to 111 degrees.

A population of rabbits doubles every 4 months. If the population starts out with 8 rabbits how many will there be in 1 year
Given:
The initial population of rabbit = 8
Population of rabbits doubles every 4 months.
To find:
The number of population in 1 year.
Solution:
The exponential growth model is
[tex]y=a(b)^x[/tex] ...(i)
Where, a is the initial population, b is growth factor, x is time period.
We know that,
12 month = 1 year
So, there are 3 time period of 4 months in an year.
Initial population of rabbit (a) = 8
Population of rabbits doubles every 4 months. So, growth factor is 2, i.e., b=2 and the time period is 3, i.e., x=3.
Putting a=8, b=2, x=3 in (i), we get
[tex]y=8(2)^3[/tex]
[tex]y=8(8)[/tex]
[tex]y=64[/tex]
Therefore, the population of rabbit in 1 year will be 64.

I want to take the measurements of my 5 avocado trees and order their
heights from shortest to tallest, that way they can get enough sunlight to
continue growing. I have to worry about sea level, so those above sea
level get sunlight more easily (positive is above sea level, negative is
below sea level). The 5 heights are in feet: 6,-3, 2,-8,-6. Please help me
order them from shortest to tallest so I plant them in the right order to get
enough sunlight.
Answer:
If we are saying everyhing above sea level is taller then plants under sea level. Then here is the order
Step-by-step explanation:
-8, -6, -3, 2, 6
And just in case it's above sea level the shortest then 6, 2, -3, -6, -8

All parts showing
Answer:
Function A has a greater initial value because the initial value for Function A is 6 and the initial vale for Function B is 3
Step-by-step explanation:
The data for Function A is presented here as follows;
[tex]\begin{array}{cc}x&y\\-1&9\\0&6\\1&3\\2&0\end{array}[/tex]
The slope of the function, 'm', is given using any two points as follows;
m = (9 - 3)/((-1) - 1) = -3
The slope of the function = -3
The equation of function in point and slope form is given as follows;
y - 3 = -3·(x - 1)
The equation of Function A, is therefore, given as follows;
y = 3 - 3·x + 3 = 6 - 3·x
∴ y = 6 - 3·x
The equation of Function B is given as follows;
y = 6·x + 3
The initial value of a function is given by the y-intercept of the function, where the input variable (x-variable) is zero
The initial value, (y-intercept) of Function A, f(0) is therefore found as follows;
f(x) = y = 6 - 3·x
f(0) = 6 - 3×0 = 6
The initial value of Function A, f(0) = 6
Similarly, the initial value, (y-intercept) of Function B, f(0) is found as follows;
f(x) = y = 6·x + 3
f(0) = 6×0 + 3 = 3
The initial value of the Function B, f(0) = 3
Therefore, we have that Function A has a greater initial value than Function B
(Help please) Find both the perimeter and the area of the following rectangle

X+6
Perimeter:_____
Area:____
Given:
Length of a rectangle = (2x+3) units
Width of the rectangle = (x+6) units
To find:
The perimeter and the area of the rectangle.
Solution:
We know that, the perimeter of the rectangle is
[tex]Perimeter=2(Length+Width)[/tex]
[tex]Perimeter=2((2x+3)+(x+6))[/tex]
[tex]Perimeter=2(3x+9)[/tex]
[tex]Perimeter=6x+18[/tex]
The area of rectangle is
[tex]Area=Length\times width[/tex]
[tex]Area=(2x+3)\times (x+6)[/tex]
[tex]Area=2x^2+12x+3x+18[/tex]
[tex]Area=2x^2+15x+18[/tex]
Therefore, [tex]Perimeter=6x+18[/tex] and [tex]Area=2x^2+15x+18[/tex].
Can someone give me the answer and explanation
Answer: A
Step-by-step explanation:
The total minus the cost of the eggs leaves you with just the total of the potatoes. Since we know that the total of the potatoes is the product of 5 bags, we can divide the total of the potatoes by 5 to find the cost of each bag of potatoes.

Who understands how to do this mess?
Answer: 140
Step-by-step explanation:
Angle 4 and A are supplementary meaning they add to 180
Thus you can do 180-40 = 140 to get that angle A = 140.
Since the two lines are parallel, Angle A is congruent to Angle D. Then, since Angle D is opposite Angle 3, we know that that Angle 3 and Angle D are congruent.

four thousand three hundred twenty-one ten thousandths as a decimal
Answer:
.4321
Step-by-step explanation:
move the decimal to the left four times
We want to write four thousand three hundred twenty-one ten thousandths as a decimal.
The number is:
4321.010
To do it, we need to understand what each place value represents, where the place values are the place of each digit in reference to the decimal point.
The first digit at the left of the decimal point represents the units.The second digit at the left of the decimal point represents the tens.The third digit at the left of the decimal point represents the hundreds.The fourth digit at the left of the decimal point represents the thousands.
And for the right we have:
The first digit at the right of the decimal point represents the tenths.The second digit at the right of the decimal point represents the hundredths.The third represents the thousandths.Of course, it continues in both ways, but this is enough to write our number.
We have:
"four thousand..."
Then the fourth digit at the left is a 4.
"... three hundred..."
The third digit is a 3.
"...twenty-one..."
The second digit is a 2, and the first is a 1.
For the right side, we do not have tenths, so the first digit at the right is a zero.
And "...ten thousandths"
We have a "10" in the second and third digits at the right of the decimal point.
Then our number is:
4321.010
