The bearing of point B from point A is 043°. Find the bearing of point A from point B.
Answers
The bearing of point A from point B is 223°.
We have given that,
The bearing of point B from point A is 043°.
We have to determine the bearing angle,
Suppose that we have the angle BAD=43 degrees.
So angle CBA=43 degrees.
What is the angle of bearing?
A bearing is an angle in degrees measured clockwise from north. Bearings are usually given as a three-figure bearing.
For example, 30° clockwise from the north is usually written as 030°.
Angle EBA= 180+∠CBA
=180°+43°
=223°
Therefore the bearing of point A from point B is 223°.

If f(x)=(4x-3) / 2 and g(x) =(2x+3) / 4, which of the following is true?
A f(g(x)) =1
B f(g (x)) = 0
C f(g(x))=-1
D f(g(x)) = x
Answers
Answer:
f(g(x))= x
Step-by-step explanation:
f(x)=(4x-3)/2
g(x) =(2x+3)/4
f(g(x)) means use the value obtained from g(x) in the equation defined by f(x). Since g(x) =(2x+3)/4, we can substitute (2x+3)/4 in place of the x in f(x).
If f(x)=(4x-3)/2 then use the expression (2x+3)/4 in place of "x" in (4x-3)/2
f(x) = (4x-3)/2
g(x) = (2x+3)/4
f(g(x))=(4((2x+3)/4)-3)/2
f(g(x))=(((8x+12)/4)-3)/2
f(g(x))= (2x+3-3)/2
f(g(x))= 2x/2
f(g(x))= x

Parallel to y=−3/4x, through (4, -1)
Answers
Answer:
y = -3/4x + 2
Step-by-step explanation:
The line is parallel to y = -3/4x and passes through the point (4, -1)
=============================================================
Solving :
⇒ As they are parallel, the slope remains the same (-3/4)
Now apply into the point slope formula :
⇒ y + 1 = -3/4 (x - 4)
⇒ y + 1 = -3/4x + 3
⇒ y = -3/4x + 2 [in slope-intercept form]
Which equation represents a line that is parallel to the line that passes through the points (−6,9) and (7,−17)?
Answers
Answer: y - 17 = -2(x-7)
Step-by-step explanation:
point-slope form: y - y1 = m(x - x1)
m = y2-y1/x2-x1
= 9+17/-6-7
= 26/-13
= -2
y1 = -17
x1 = 7
y - 17 = -2(x-7)
The equation represents a line that is parallel to the line that passes through the points (−6,9) and (7,−17) is y = -2x - 3
What is the general equation of a straight line?The general equation of a straight line is-
y = mx + c
where, m is the gradient and is given by y₂ - y₁/x₂ - x₁
and, c is the value where the line cuts y-axis.
Now it is given that the line passes through points (−6,9) and (7,−17)
Therefore we have,
x₁ = -6, y₁ = 9, x₂ = 7, y₂ = -17
So, the slope m of the line is given as,
m = (y₂ - y₁)/(x₂ - x₁)
Put the values,
m = (-17 - 9)/(7 - (-6))
m = -26/7+6
m = -26/13
m = -2
Thus, the equation parallel to the line will be given as:
y - y₁ = m(x - x₁)
y - 9 = -2{x - (-6)}
y - 9 = -2(x + 6)
y = -2x - 12 + 9
y = -2x - 3
Thus, the equation represents a line that is parallel to the line that passes through the points (−6,9) and (7,−17) is y = -2x - 3

Triangle ABC is an isosceles right triangle. What is the measure of one base angle?
Answers
Answer:
45°
Step-by-step explanation:
ΔABC is an isosceles right triangle. So, one angle is 90°
In an isosceles triangle, base angles are congruent.
Let the base angles be x ,x
x + x +90 = 180 {Angle sum property}
2x + 90 = 180
2x = 180 - 90
2x = 90
x = 90/2
x = 45
Base angle = 45°

Identify the angle of depression.
Answers
Answer:
4
Step-by-step explanation:
An angle of elevation is the angle formed by a horizontal line and a line of sight to a point above the line.
An angle of depression is the angle formed by a horizontal line and a line of sight to a point below the line.
∠3 is an angle of elevation because it is formed by the line of sight that is above the horizontal line.
∠4 is an angle of depression because it is formed by the line of sight that is below the horizontal line.
∠5 is neither an angle of depression nor an angle of elevation because it is not formed by the horizontal line and the line of sight.
∠6 is an angle of elevation because it is formed by the line of sight that is above the horizontal line.
Therefore, the angle of depression is ∠4.

You need to invest $1000 in a bank account and are give two options. The first option is to earn $50 every month you leave the money in the account. The second one is to earn 3% interest each month. Describe each of these two functions and make a table of values for each for several months. Which account would you choose?
Answers
Answer:
Option 1Earn $50 every month.
Let x = number of months the money is left in the accountLet y = the amount in the accountInitial amount = $1,000[tex]\implies y = 50x + 1000[/tex]
This is a linear function.
Option 2Earn 3% interest each month.
(Assuming the interest earned each month is compounding interest.)
Let x = number of months the money is left in the accountLet y = the amount in the accountInitial amount = $1,000[tex]\implies y = 1000(1.03)^x[/tex]
This is an exponential function.

From the table of values, it appears that Account Option 1 is the best choice, as the accumulative growth of this account is higher than the other account option.
However, there will be a point in time when Account Option 2 starts accruing more than Account Option 2 each month. To find this, graph the two functions and find the point of intersection.
From the attached graph, Account Option 1 accrues more until month 32. From month 33, Account Option 2 accrues more in the account.
ConclusionIf the money is going to be invested for less than 33 months then Account Option 1 is the better choice. However, if the money is going to be invested for 33 months or more, then Account Option 2 is the better choice.

Mary is planning a costume party. She spent $375.00 as shown on the graph. How much of the money was spent, to the nearest dollar, on the following items?
1) On decorations?
2) On food?
3) On party hall rental?
4) On prizes?
5) On invitations?
Answers
For the first, decorations, Mary spent $?? as shown by the blue triangle on the pie chart. Let’s get the other ones first to total the money left over.
For the second, she spent $65 on food, as shown by the green triangle on the pie chart.
For the third, she spent $80 on party hall rental, as shown by the blue triangle on the pie chart.
For the fourth, she spent $30 on prizes, as shown by the dark blue triangle.
And for the fifth one, she spent $45 on invitations. A bit too expensive if you ask me.
Then we add all the costs together, and get 220. After adding the extra costs such as candy, costumes, and music, we get a total of $345. We would subtract this from $375 to get a total of $30 left over, which was spent on decorations. The ??? value of the light blue triangle is $30.
Hope this helps!
