Step-by-step explanation:

Answer:

n = 7 1/3 weeks

Step-by-step explanation:

Amount Jabari wants to save = $66

Amount he earns per week = $9

Hours worked per week = 2 hours

How many weeks will it take him to save $66?

Let

n = number of weeks will it take him to save $66

66 = 9n

n = 66/9

n = 7 3/9

n = 7 1/3 weeks

Or

n = 7.33 weeks

Answer:

(1) First pair; (2, 3), (7, 3), d₁ = 5

(2) Second pair; (-2, 5), (-2, -3), d₂ = 8

(3) Third pair; (-8, 5), (-2, 5), d₃ = 6

(4) Fourth pair; (-9, 1), (6, 1), d₄ = 15

Step-by-step explanation:

Given pair of points;

(1)  (2, 3), (7, 3)

(2) (-2, 5), (-2, -3)

(3) (-8, 5), (-2, 5)

(4) ) (-9, 1), (6, 1)

The distance between each pair of points is calculated as follows;

[tex]d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2}[/tex]

(1) first pair; (2, 3), (7, 3)

[tex]d_1 = \sqrt{(3-3)^2 + (7-2)^2} \\\\d_1 = 5[/tex]

(2) second pair; (-2, 5), (-2, -3)

[tex]d_2 = \sqrt{(-3-5)^2 + (-2-(-2))^2}\\\\d_2 = \sqrt{(-3-5)^2 + (-2+2)^2} \\\\d_2 = 8[/tex]

(3) Third pair; (-8, 5), (-2, 5)

[tex]d_3 = \sqrt{(5-5)^2 + (-2-(-8))^2}\\\\d_3 = \sqrt{(5-5)^2 + (-2+8)^2} \\\\d_3 = 6[/tex]

(4) Fourth pair; (-9, 1), (6, 1)

[tex]d_4 = \sqrt{(1-1)^2 + (6-(-9))^2}\\\\d_4 = \sqrt{(1-1)^2 + (6+9)^2} \\\\d_4 = 15[/tex]

Answer:

y=-1/6x

Step-by-step explanation:

To find the answer you can just look at 2 points on the graph and whichever one comes first is (y1,x1) and the next pair is (y2,x2). So to find it we can use (0,0) automatically because the line is crossing through it. We can also use (600,-100) as the second point becasue it is the next farthest away and when we plug the numbers into the slope equation(y2-y1/x2-x1) we get -100-0/600-0 which when simplified is -100/600 or -1/6 so that would be the m in slope-intercept form (y=mx+b) and when you get everything you can find the equation y=-1/6x

Step-by-step explanation:

Answer:

The resultant speed = 181.3 mph

The final direction = 38.7° northeast.

Step-by-step explanation:

We need to find the component in the x-direction and in the y-direction of the speed:

For the plane:

[tex] v_{p_{x}} = 200cos(45) = 141.42 [/tex]

[tex] v_{p_{y}} = 200sin(45) = 141.42 [/tex]

For the wind we have:

[tex] v_{w_{x}} = -28 [/tex]

[tex] v_{w_{y}} = 0 [/tex]

Now, the total speed in the x-direction and  in the y-direction is:

[tex] V_{x} = v_{p_{x}} + v_{w_{x}} = 141.42 - 28 = 113.42 [/tex]

[tex] V_{y} = v_{p_{y}} + v_{w_{y}} = 141.42 [/tex]

Hence, the resultant speed is:

[tex] V = \sqrt{V_{x}^{2} + V_{y}^{2}} = \sqrt{(113.42)^{2} + (141.42)^{2}} = 181.3 mph [/tex]

Finally, the direction of the plane is:

[tex] tan(\theta) = \frac{V_{y}}{V_{x}} = \frac{141.42}{113.42} = 1.25 [/tex]

[tex] \theta = 51.3 ^{\circ} [/tex]

[tex] \theta = 90 - 51.3 = 38.7 ^{\circ} [/tex]

The plane is moving at 38.7° northeast.

Answer:

6m - 15 = 9m+9

Step-by-step explanation:

Looking at option b;

6m - 15 = 9m+9

Collect the like terms

6m-9m= 9 + 15

-3m = 24

Divide both sides by -3

-3m/-3 = 24/-3

m = -8

Hence the equation that has -8 as solution is 6m - 15 = 9m+9

The length of AC is 6.4 unit.

The correct option is C.

We have the figure from which we can say that

BD is the diameter which is

= 4.8 + 1.6

= 6.4 unit long.

Now, AC is the chord.

As, the distance between the two opposite point the the surface of circle would be same.

Then, the length of AC = length of BD

Thus, the length of AC is 6.4 unit.
