The graph of g(x)=f(x)-d crosses the y-axis at (0,c-d).

What does y-intercept mean?

The point on a line where it crosses the y-axis is known as the y-intercept. To put it another way, it is the value of y when x is equal to 0.

It is given that graph  [tex]f(x)=ce^{x}[/tex] crosses the y-axis at (0,c).

Because at x=0,

[tex]f(0)=ce^{0}\\f(0)=c[/tex].

So, if g(x)=f(x)-d

[tex]g(x)=ce^{x}-d[/tex]

when x=0:

So the graph of g(x)=f(x)-c touches the y-axis at (0,c-d).

The maximum number of hours is 1.6 hours and the minimum  number of hours is 1.6 hours.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, a plane is flying at a speed of 175 miles per hour.

The distance covered by the pilot, d = 250 ± 25 miles

We know that, speed = Distance/Time

The equation for the maximum number of hours is given as;

175 =(250+25)/t

t=275/175

t=1.6 hours

The equation for the minimum number of hours is given as;

175 =(250-25)/t

175=225/t

t=225/175

t=1.3 hours

Therefore, the maximum number of hours is 1.6 hours and the minimum  number of hours is 1.6 hours.

Answer:1024 grid squares

Step-by-step explanation:

Let's call the side length of the original piece of graph paper "x".

Since, side length of the cut out square is then (x-2) because the cut out square has to have an integer number of grid squares, and each side of the square would take up 2 grid squares on the graph paper.

The number of grid squares in the cut out square is then (x-2)^2.

The number of grid squares left on the graph paper is 124, so we have:

x^2 - (x-2)^2 = 124

Expanding the right side:

x^2 - x^2 + 4x - 4 = 124

Simplifying:

4x = 128

therefore:

x = 32

therefore original graph paper contains 32 grids i.e 32^2 = 1024

Answer:

  any of {128, 133, 140, 160, 224, 320, 380, 700, 1024}

  1024 if the original grid was square

Step-by-step explanation:

You want to know how many grid squares are on a piece of graph paper if a square number of grid squares can be cut from it to leave 124 grid squares.

If the graph is square to begin with, a square of x² can be removed from its size (x+a)² to leave 124 squares. That is ...

  (x +a)² -x² = 124

  (a)(2x+a) = 124

The factor pairs of 124 are ...

  124 = 1·124 = 2·62 = 4·31

Of these, only 2 and 62 differ by an even number, so we have a=2 and x=30.

The graph paper could be 32 units square originally, having 1024 grid squares.

There is nothing in the problem statement that requires the original graph paper be square. If it is not necessarily square, there are 13 possible shapes it could be. Those have 9 different possibilities for numbers of grid squares.

The graph paper could have originally had this number of grid squares:

Thus, the required rest stops are approximately 4.09 miles apart on the new map.

The scale factor is defined as the ratio of the modified change in length to the original length.

Here,
The total length of the highway in miles can be found by using the scale of the original map. Since 2 inches on the map represent 33 miles in reality, 6 inches on the map represent:

= 6 inches × (33 miles/2 inches) = 99 miles

Since there are 11 equally spaced rest stops along the highway,

= (99 miles)/(11 intervals) = 9 miles per interval

To create the new map with a scale of 1 inch = 30 miles, we need to use a scale factor of (1/2) × (30/33) = 15/33.

Therefore, the distance between each rest stop on the new map can be found by multiplying the distance between rest stops on the old map by the scale factor,

= (9 miles per interval) × (15/33) = 4.09 miles per interval

So, the required rest stops are approximately 4.09 miles apart on the new map.

Answer: 2021

Step-by-step explanation:

The total amount of time McKenna spends on her chores is 41/8 hours, or approximately 5.125 hours.

To find the total amount of time McKenna spends on her chores, we need to add up the time she spends mopping the floors and mowing and weeding the yard.

First, let's convert both the time spent mopping the floors and mowing and weeding the yard to a common denominator. The least common multiple of 4 and 8 is 8, so we can convert 7/4 hours to

7/4 * 2/2 = 7/2 hours.

Next, we can add the time spent on each chore:

7/2 hours + 27/8 hours = (14 + 27)/8 hours = 41/8 hours.

So, the total amount of time McKenna spends on her chores is 41/8 hours, or approximately 5.125 hours.

It is important to note that this calculation assumes that the time spent on each chore is a continuous amount of time, rather than broken up into smaller increments throughout the day.

The correct answer to the given question about all of the diagonals drawn from a vertex of an n-gon is option b) n-1

If all of the diagonals are drawn from a vertex of an n-gon, the number of triangles formed is equal to the number of non-diagonal sides of the n-gon. To see why, imagine selecting a vertex of the n-gon and drawing all of the diagonals from that vertex. Each diagonal connects that vertex to a non-adjacent vertex of the n-gon, which splits the n-gon into a series of triangles. The total number of triangles formed is equal to the number of non-diagonal sides of the n-gon, because each non-diagonal side forms one triangle with the selected vertex and one of its adjacent vertices. An n-gon has n sides, so the number of non-diagonal sides is equal to n - 3. This is because each vertex is connected to two adjacent vertices, so there are n - 2 diagonal sides emanating from the selected vertex, and the remaining n - 2 sides are non-diagonal. In addition, there are three sides at the selected vertex that are not counted as non-diagonal sides, so we subtract 3 from n - 2 to get n - 3. Therefore, the answer is (B) n - 1.

m = slope which is the rate of change of y with respect to x
b = y-intercept which is the value of y when x = 0; also the y-value where the line crosses the y-axis

To find m:

To find b:

So the equation of the line is

There are 2002 groups of 5 people that can answer the 5 phone lines.

This is a combination problem, because we want to choose groups of 5 people from a group of 14, and the order in which we choose the people does not matter.

The formula for the number of combinations of n objects taken r at a time is:

C(n,r) = n! / (r! * (n-r)!)

In this case, we want to choose 5 people out of a group of 14, so we can plug those values into the formula:

C(14,5) = 14! / (5! * (14-5)!)

Simplifying the factorial terms:

C(14,5) = (1413121110) / (54321)

C(14,5) = 2002

where x is = the individual height, μ is = the mean height, and σ is = the standard deviation.

Substituting the values, we get  ;

⇒ z = (63.4 - 69.0)/2.8  ;

Simplifying, we get:

⇒ z = -5.6/2.8 = -2  .
