The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:
Montano1993 [528]

Answer:

0.2 miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.

Step-by-step explanation:

As there is no graph mentioned here but the information are quite sufficient to answer the question.

We have points (0,3), (5,4),(10,5)...

From these points we can find the slope of the line .

From point slope formula y-y_1=m(x-x_1)

And assigning (x,y) (0,3) and (x_1,y_1) (5,4)

m=\frac{y_1-y}{x_1-x} =\frac{4-3}{5-0} =\frac{1}{5}=0.2

This slope is also the speed of the bird which is 0.2\ miles\ per\ minute.

As by plugging the values of any coordinate point we can confirm this.

Lets put (10,5), y-axis is the distance so in 10 minutes the the distance covered by the bird must be equal to to y-axis value which is 5 miles.

y=0.2(x),y=0.2(10)=5\ miles

Now as in t=0 the bird has started from y-intercept value 3 so we can say that,the original distance of the bird from its nest is 3\ miles.

So the correct choices are:B and D

The birds speed is 0.2\ miles per minute and is 3\ miles away from its nest.

Ann, Bob, Carol, and Denis own a candy store. After a large argument, they decide to dissolve their partnership using the sealed
MaRussiya [10]

Answer:

Following are the solution to the given points:

Step-by-step explanation:

Ann=\$3,20,000\\\\Bob=\$4,40,000\\\\Carol=\$240,000\\\\Denis= \$4,00,000\\\\

Each player's offer divided by the total number of players calculates the fair share

Ann's fair share = \frac{\$320,000}{4} = \$80,000\\\\

Bob's fair share= \frac{\$440,000}{4} = \$110,000\\\\

 Carol's fair share = \frac{\$240,000}{4} = \$60,000\\\\

Denis's fair share = \frac{\$400,000}{4} = \$100,000\\\\

 Because Bob has the highest bid, that receives in the business.

Payments:

 Ann \$80,000 paid by estate

 Bob = \$440,000 - \$110,000 = \$330,000 owes estate

 Carol = \$60,000 paid by estate

 Denis = \$100,000 paid by estate  

Surplus = \$330,000 - (\$80,000+\$60,000+ \$100,000) = \$90,000  

Splitting the equally among the four players. therefore one of the each receives:

\frac{\$90,000}{4}= \$22,500

The final settlement of the Ann receives:

= \$80,000+ \$22,500 = \$102,500

The graph of the quadratic function f(x) is shown below. What is one of the solutions of the equation?
Vaselesa [24]

Answer:

x = -2

Or

x = 4

Step-by-step explanation:

The solutions of the quadratic function that is represented by the graph shown above, is the x-intercepts of the graph.

The x-intercepts are the values of x, when y = 0. At any of these x-values, the parabola intercepts the x-axis.

Therefore, the graph shows that the parabola intercepts the x-axis when x = -2 and also when x = 4.

The solutions of the equation of the graph are x = -2, and x = 4.
