Answer:

(4,14)

Step-by-step explanation:

plug in ordered pairs for the given equation and see which one works. ordered pairs are simply (x,y) and the equation just so happens to have x and y variables. when x in the equation equals 4 then 3.5*4 is equal to 14 which is the y value of the first ordered pair. try it with the others and they don't work. is x equaled 28 then 3.5*28 is 98 and that paired y is only 8 so no. do it with all ordered pairs if you must. it's an elimination game

The ordered pairs (4, 14), and (3, 28) satisfy the equation y = 3.5x.

An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.

Pair in Order = (x,y)

x is the abscissa, the distance measure of a point from the primary axis x

y is the ordinate, the distance measure of a point from the secondary axis y

The given equation for the pounds of fruits 'x' and the total cost 'y' is,

y = 3.5x.

Now, The ordered pairs that satisfy the equation can be obtained by putting the value of 'x' and checking the corresponding 'y' value.

(4, 14).

y = 3.5×4.

y = 14. (satisfies).

Similarly,

(3, 28), also satisfies the equation y = 3.5x.

Answer:

Step-by-step explanation:

Answer:

20.2 miles

Step-by-step explanation:

This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:

[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]

[tex]/24/^{2}[/tex] = [tex]/x/^{2}[/tex] + [tex]/13/^{2}[/tex]

576 = [tex]x^{2}[/tex] + 169

[tex]x^{2}[/tex] = 576 - 169

   = 407

x = [tex]\sqrt{407}[/tex]

  = 20.1742

x = 20.2 miles

The glider has to fly 20.2 miles to return to the airport.

Answer:

1 : 4 : 9

Step-by-step explanation:

Given the ratio of diameters = a : b , then

ratio of areas = a² : b²

Here ratio of diameters = 1 : 2 : 3 , so

ratio of areas = 1² : 2² : 3² = 1 : 4 : 9

Answer:

1,250 meters.

Step-by-step explanation:

If you convert the 2 km into meters, you get 2000 meters. So after that you subtract 2000-750 and you should get 1,250

Hope this helps

2 kilomters = 2000 meters

Thus, to find out how much closer Adrian lives next to his school than Kevin you subtract the distance from kevin's home to his school (2000 meters) by the distance of Adrian's home to his school (750 meters).

2000 - 750 = 1250 meters

Therefore, Adrian lives 1250 meters closer to his school than Kevin.

Step-by-step explanation:

Given:

A right triangle has legs of 18 inches and 24 inches.

The short leg is increasing by 4 in/sec and the long leg is  shrinking at 9 in/sec.

To find:

The rate of change of the hypotenuse.

Solution:

Let x be the shorter leg (Base), y be the larger leg (Perpendicular) and z be the hypotenuse.

We have,

[tex]\dfrac{dx}{dt}=4\text{ in/sec}[/tex]

[tex]\dfrac{dy}{dt}=-9\text{ in/sec}[/tex]

[tex]x=18[/tex]

[tex]y=24[/tex]

According to the Pythagoras theorem,

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

[tex]z^2=x^2+y^2[/tex]           ...(i)

[tex]z^2=(18)^2+(24)^2[/tex]

[tex]z^2=324+576[/tex]

[tex]z^2=900[/tex]

Taking square root on both sides.

[tex]z=\pm \sqrt{900}[/tex]

Side cannot be negative. So,

[tex]z=30[/tex]

Differentiating (i) with respect to time t, we get

[tex]\dfrac{d}{dt}z^2=\dfrac{d}{dt}(x^2+y^2)[/tex]

[tex]2z\dfrac{dz}{dt}=2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}[/tex]

[tex]2(30)\dfrac{dz}{dt}=2(18)(4)+2(24)(-9)[/tex]

[tex]60\dfrac{dz}{dt}=144-432[/tex]

[tex]60\dfrac{dz}{dt}=-288[/tex]

Divide both sides by 60.

[tex]\dfrac{dz}{dt}=\dfrac{-288}{60}[/tex]

[tex]\dfrac{dz}{dt}=-4.8[/tex]

Here, negative sign means hypotenuse is decreasing.

Therefore, the hypotenuse is shrinking at 4.8 in/sec.

Answer:

The measure of an interior angle of a regular 15-gon is 120°.

Step-by-step explanation:

We need to determine the measure of the size of an interior angle of a regular 15-gon having 15 sides.

Thus,

The number of sides n = 15

Hence,

Using the formula to determine the measure of an interior angle of a regular 15-gon is given by

(n - 2) × 180° = n × interior angle

substitute n = 15

(15 - 2) × 180 = 15 × interior angle

13 × 180 = 15 × interior angle

Interior angle = (10 × 180) / 15

                      = 1800 / 15

                      = 120°

Therefore, the measure of an interior angle of a regular 15-gon is 120°.
