SOCCER Alice kicks a soccer ball towards a wall. The ball is deflected off the wall at an angle of 40°,
and it travels 6 meters. How far is the soccer ball from the wall when it stops rolling?
Answers
Answer:
The ball is 3.86 meters from the wall when it stops rolling.
Step-by-step explanation:
Representation of the situation:
This situation can be represented by a right triangle:
The hypotenuse is the distance the ball traveled, of 6 meters.
The distance from the wall is the side opposite to the angle of 40º.
We have that:
Sine of an angle is the length of the opposite side divided by the hypotenuse. So, in this situation.
Sine of 40 degrees = Distance from the wall/6
Sine of 40 degrees is of 0.64278760968.
Distance = 6*0.64278760968 = 3.86.
The ball is 3.86 meters from the wall when it stops rolling.

Find x if the average of 19, 12, 14, 18, and x is 12.
Answers
Answer:
-3
Step-by-step explanation:
To do this, let's arrange it into an equation:
(19+12+14+18+x) / 5 = 12
Let's shift the 5 to the other side by multiplying 12 by 5, which is 60. Now the equation looks like this:
19+12+14+18 + x = 60
Now let's add 19, 12, 14 and 18 together, which is 63:
63 + x =60
Let's move the 63 over to the other side by subtracting it from 60, so 60-63 equals -3. Hence, the answer is -3. Hope this helps!

Your gas company charges you a standing charge of 9 pence per day and 2 pence per kilowatt-hour (KWh).

How much is your bill for the last quarter?
Answers
Answer:
$8.10 + 55.50 x $2 KW
= 8.10 + 111.00 = $119.10
Step-by-step explanation:
d = days and x = kw/h
9d = 2x = 9(90) = 500m3
1 unit m3 = 11.1 kwh
We rewrite
9(90) = 500 x 11.1
500 x 11.1 = 5550 KW
0.09 x 90 = 5550 KW
8.1 + 5550 x 0.02
= 8.1 + 111 KW
= 119.10
= $119.10
Write a rule for the nth term of the arithmetic sequence. Then graph the first six terms of the sequence. a6=-12 a12=-36
Answers
Answer:
We need to find the first term. We can use the formula
an = a1 + d(n - 1)
to solve for a1. We already know the 12th term, a12, common difference, d, and nth sequence, n.
a12 = -36
d = -4
n = 12
-36 = a1 - 4(12 - 1)
-36 = a1 - 44
8 = a1
The first term is 8. Therefore, your formula is
an = 8 - 4(n - 1)
an = -4n + 12
Then use this formula to graph.
n is the independent variable.
an is the dependent variable.
Your graph will be a line.

Answer:
4x + 10
Step-by-step explanation:
Given
Let
[tex]t = time[/tex]
[tex]s = speed[/tex]
So:
[tex]t = 2; s = (2x +5)[/tex] --- first 2 hours
[tex]t = 3; s = (3x -5)[/tex] --- last 3 hours
Required
Distance covered in the first 2 hours
Distance (d) is calculated as:
[tex]Distance = speed * time[/tex]
i.e.
[tex]d = s * t[/tex]
For the first 2 hours, we have:
[tex]t = 2; s = (2x +5)[/tex]
So:
[tex]d = (2x + 5) * 2[/tex]
Open bracket
[tex]d =2x * 2 + 5 * 2[/tex]
[tex]d =4x + 10[/tex]
Hence, the distance covered in 4x + 10
