The function f(x) represents the time it takes an airplane to travel east. The function g(x) represents the time it takes an airplane to travel west. Given f(x) = 4x 13 and g(x) = 10x − 2, solve for (f g)(x) to determine the total roundtrip time. (f g)(x) = 14x 15 (f g)(x) = 14x 11 (f g)(x) = 6x 11 (f g)(x) = 6x 15.
Answers
The total time taken for round trip will be (f+g)(x) = 14x+11
We have given that
f(x)=4x+13and g(x)=10x-2
What is the round trip time?In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.
Therefore we get,
[tex](f+g)(x)=f(x)+g(x)\\ =(4x+13)(10x-3)\\ =4x+13+10x-2\\ =4x+10x+13-2\\ =14x+11[/tex]
Hence,The total time taken for round trip will be: (f+g)(x) = 14x+11

An angle measures 82º more than the measure of its complementary angle. What is the measure of each angle?
Answers
Answer:
Step-by-step explanation:
Let one angle be x
Other angle =x + 82
Complementary angles add up to 90
x + x + 82 = 90
2x + 82 = 90
2x = 90 - 82
2x = 8
x = 8/2
x = 4
Other angle = x + 82
= 4 +82
= 86
The angles are: 4 , 86
An angle measures 82º more than the measure of its complementary angle. What is the measure of each angle?
❖ Explanation -:Given -:
An angle measures 82º more than the measure of its complementary angle.Need to find -:
Measure of each angleAssuming -:
An angle measures 82º more than the measure of its complementary angle.
Let us assume one angle as x
Then other angle = (x + 82)
Solution -:
First we will make an equation
We know,
Complementary angles add up to 90°
x + (x + 82°) = 90°
→ x + x + 82° = 90°
→ 2x + 82° = 90°
→ 2x = 90° - 82°
→ 2x = 8
→ x = [tex]\cancel{\dfrac{8}{2}}[/tex]
→ x = 4
Substituting the value of x = 4
One angle = x = 4°
Other angle = x + 82° = (4 + 82)° = 86°
Final Answer -:
The angles are 4 and 86.[tex] \rule{180pt}{2pt}[/tex]
In a certain chemical, the ratio of zinc to copper is 3 to 19. A jar of the chemical contains 494 grams of copper. How many grams of zinc does it contain?
enter your response here
It contains grams of zinc.
Answers
Answer:
3216 grams of Zn
Step-by-step explanation:
It is not clear from the question if the ratio is based on the chemical formula, and is thus the ratio of atoms, or if it is based on mass (in g). I'll assume it is based on the numbers of Zn and Cu atoms.
Let's convert the mass of copper, 494 grams, to moles of copper (representative of the number of atoms). The molar mass of copper, Cu, is 63.55 grams/mole.
Moles Cu =(494 grams)/(63.55 grams/mole) = 7.77 moles Cu
If zinc (Zn) is in a ratio of 19/3, we would have:
(19 moles Zn/3 moles Cu)*(7.77 moles Cu) = 49.2 moles of Zn
The molar mass of zinc is 65.38 grams/mole
The mass of 49.2 moles of Zn is:
(49.2 moles Zn)(65.38 grams/mole) = 3216 grams of Zn

Alfie has two sticks he puts the end to end in total it equals 80cm one stick is 10cm longer than the other stick how long is the longest stick
Answers
Solving
Alright so we know there are two sticks and that one is 10cm longer than the other. Knowing this information we can start off by dividing the total to make the sticks equal in length.
80cm ÷ 2 = 40cm
^ So currently each stick is 40cm
From here we have to make one stick 10cm longer so we would subtract 10cm from one and add that 10cm to the other one.
Stick 1: 40cm - 10cm = 30cm
Stick 2: 40cm + 10cm = 50cm
Answer
This means that the longest stick is 50cm in length
The length of the longest stick is 45cm.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Let's call the length of the shorter stick "x".
According to the problem, the longer stick is 10cm longer than the shorter stick, so its length is x + 10.
Now we know that when the two sticks are put end to end, the total length is 80cm.
Therefore, we can write the equation:
x + (x + 10) = 80
Simplifying the equation, we get:
2x + 10 = 80
Subtracting 10 from both sides:
2x = 70
Dividing both sides by 2:
x = 35
The length of the shorter stick is 35cm, and the length of the longer stick is:
x + 10 = 35 + 10 = 45
Therefore,
The length of the longest stick is 45cm.

What are the slope and y-intercept of the linear function shown in the grid?
Answers
Answer:
C Slope = -4/3, Y-Intercept = 4
Step-by-step explanation:
The Y- Intercept is where the line contacts the Y-Axis (the vertical line)
Since the line is going down, the slope is going to be negative. You fine the slope by finding a point the line goes through perfectly and then since its negative, go down however many it is until the line goes through another point perfectly, then go right and how many points it takes to get to the point is your denominator. (so your slope is -4/3)

To complete the paragraph proof, we have;

m<2 - m<3 = m<2 - m<1
m<1 + m<2 = m<2 + m<3 (by the addition property of supplementary angles)
