Answer 1

A function is a relationship where each input (the x axis) has only one output (the y axis). This means that for every x value, there must only be one y value. As the graph shows only one y value for each x value (for example, if the graph were to be a straight vertical line it would not be a function), this is a function!

Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving at a constant rate of 50 mi/h. Complete the function that models the distance they drive as a function of time. Then complete a reasonable domain for this situation.

Answers

1. The total distance will be equal to 20 miles plus the remaining distance which would be obtained when you multiply the speed to time t. The equation would be written as follows:

120 = 20 + 50t

2. The minimum time would be 0 hours. The maximum time is when the total distance of 120 is fully covered.

t ≤ (120 - 20)/50
t ≤ 2 hours

Thus, the domain would be 0 < t ≤ 2.

The function that models the distance they drive as a function of time is 120 = 20 + 50t

The required domain must be within the range of 0 and 2 i.e. 0≤t≤2

The formula for calculating distance travelled is expressed as:

Distance = Speed × time

Given the following

Total distance = 120 miles

Distance already travelled = 20miles

If they are trying at a constant rate of 50mi/hr, the distance travelled at the time "t", this period will be 50t.

The required function that models the distance is expressed as;

120 = 20 + 50t

Hence the function that models the distance they drive as a function of time is 120 = 20 + 50t

To get a reasonable domain, we need to get the value of t as shown;

120 = 20 + 50t

120 - 20 = 50t

100 = 50t

t = 100/50

t = 2sec

Hence the required domain must be within the range of 0 and 2 i.e. 0≤t≤2

What is proportion?

It is the equality between two or more ratios derived from measurements extracted from quantities. When two ratios have the same result, we say they are proportional. If these ratios represent measures of some magnitude, we also say that they are proportional.

So we know that a proportion is given by the equality between two ratios and the resolution process consists of the following situation: “the product of the extremes is equal to the product of the means” or using the eventual cross multiplication.

To meet building codes, a building must have a roof no taller than 74 feet. An architect is designing a museum with a 14 ½ foot ground floor, and 12 foot 3 inch upper floors (including supports) How many floors, including the ground floor, can the building have?

Answers

Answer:

Building can have 4 floors.

Step-by-step explanation:

Height of the ground floor is 14.5 foot and height of upper floors = 12 foot 3 inches or 12.25 foot per floor

Let there are x floors in the building.

Total height of the building = 74 foot

Therefore, total height of the building = Height of the ground floor + Height of the upper floors

74 = 14.5 + 12.25x

74 - 14.5 = 12.25x

12.25x = 59.5

x = [tex]\frac{59.5}{12.25}[/tex]

x = 4.9 floors

Therefore, the building can have 4 floors.

If (2x^2 - 5x + 7) is subtracted from (4x^2 + 2x - 11),

= (4x^2 + 2x-11) - (2x^2 - 5x + 7)

= 4x^2 + 2x - 11 - 2x^2 + 5x - 7

= (4 - 2)x^2 + (2 + 5)x - (11 + 7)

= 2x^2 + 7x - 18

I have chosen 4 MYSTERY INTEGERS. At least one is positive and one is negative.
Follow these clues to figure out my integers. BE SURE TO EXPLAIN YOUR REASONING!
1. The sum of the four integers is (-6)
2. When you order the integers from LEAST to GREATEST the difference of the middle two integers is (-4) and the sum is 0
3. The quotient when you divide the LEAST integer by the GREATEST is (-3)
4. The product of the two greatest integers is (+6)

Answers

Let the four numbers be A,B,C,D in ascending order.

The key is in conditions 2 & 3.
B-C=-4, and B+C=0
therefore B=-2, C=2 by solving the two previous equations.

Given that the product of the two greatest numbers is 6, we have C*D=6, or
D=6/C=6/2=3
Now since the sum of all the four numbers is -6, we have
A+B+C+D=-6
A-2+2+3=-6
A=-6+2-2-3=-9
Check: we were told smallest divided by greatest = A/D=-9/3=-3 ok.

So the numbers are
A=-9, B=-2, C=2, D=3.

Carmen cuts a 60 inch long wire into pieces that are 3/4 inch long. How many pieces does she have?

Answers

Basically, she is dividing a 60 inch long wire into 3/4 pieces. So, what we have to do here is divide 60 by 3/4.

= 60 ÷ 3/4

Keep the first number, change the sign, and flip the fraction.

= 60 × 4/3

You can reduce the numbers by the GCF (greatest common factor) of 3.

= 20 × 4/1

After reducing 60 to 20 and 3 to 1, you are left with 20 × 4/1 or simply 20 × 4.

Multiply the numbers as usual, and you will get your product of 80.

The midpoint of AB is M (4,2). If the coordinates of A are ( 6,-4) what are the coordinates of B?

Answers

Final answer:

The coordinates of point B are calculated using the midpoint formula. Substituting given values for points A and M allows us to find B's coordinates, which are (2, 8).

Explanation:

The midpoint of a line segment is calculated using the formula M=(x1 +x2)/2, (y1+y2)/2 where x1 and y1 are the coordinates of the first point and x2, y2 are the coordinates of the second point. Given that the coordinates of point A are (6,-4) and the coordinates of the midpoint M are (4, 2), we can set up the following equations to solve for the coordinates of point B (x2, y2): (6+x2)/2 = 4 and (-4+y2)/2 = 2. Solving for x2 and y2 gives us the coordinates of Point B: (2, 8).
