Answer:
The number of car washed per club is:
The art club = 533 cars
The music club = 633 cars
The drama club = 414 cars
Step-by-step explanation:
The art club, music club, and drama club at Glendale High School raised money last summer by washing cars.•
For the art club
The art club raised about $3,200 and charged $6 per car.•
$6 = 1 car
$3200 = x
6x = 3200
x = 3200/6
x = 533.33333333 cars
Approximately = 533 cars
The music club earned approximately $3,800, charging $8 for each car
$8 = 1 car
$3800 = x
8x = 3800
x = 3800/8
x = 633.33333333 cars
Approximately = 633 cars
The drama club took in nearly $2,900, at a cost per car of $7.
$7= 1 car
$2900 = x
7x = 2900
x = 2900/7
x = 414.28571429 cars
Approximately = 414 cars
The number of car washed per club is:
The art club = 533 cars
The music club = 633 cars
The drama club = 414 cars
If the value of cos(θ) is negative, this angle (θ) can only be in one of two quadrants; the sine quadrant or the tan quadrant. In the sine quadrant, tan(θ) must be negative, but since tan(θ) > 0, we can safely say that the angle (<span>θ) is based in the tan quadrant.
We know that cos(</span><span>θ) = - Adjacent / Hypotenuse, and in this case Adjacent = 2 and Hypotenuse = 5. Using Pythagoras' theorem, we can find the opposite side of the right angled triangle situated in the tan quadrant...
</span>Adjacent² + Opposite² = Hypotenuse²
Therefore:
2² + Opposite² = 5²
Opposite² = 5² - 2²
Opposite² = 21
Opposite = √(21)
------------
Now, sin(θ) must be negative, as the right angled triangle is in the tan quadrant. We also know that sin(<span>θ) = Opposite / Hypotenuse, therefore:
sin(</span><span>θ) = - [</span>√(21)]/[5]
Answer:
-3
Step-by-step explanation:
Given the points, we can see that as x increases by 4, y decreases by 4, which means the slope is -1. Working backwards from (5, -8), we can decrease x by 5 (and thus increase y by 5, since we're subtracting a negative) and add that to -8 to find the y-intercept = -3
Y=4x shows y as the total earnings and x as the number of windows
