Answer:
x=2
Step-by-step explanation:
(x+2)(x-6)= y
0 = x+2 0 = x-6
The zeros of the functions are at -2 and 6 using the zero product property
We know a parabola is symmetric so the vertex is 1/2 way between the zeros
(-2+6)/2 = 4/2 =2
The x coordinate of the vertex is at 2
Terrible formatting. 0 x 4? What does that mean? - x 0 4? Nobody can read that. I can't even tell what the integral is.
Is 0 x 4 supposed to mean
?
Answer:
Step-by-step explanation:
By the Intersecting secants theorem, we know that:
Then, substituting, we get:
Now we need to expand the expression:
Simplifying, we get that the value of "x" is:
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
You want to find the ratio of BC to AB. You know that the length of BC is 16 and AB is 20. So, it is 16:20. However, you want to find the simplest form so find the greatest common factor of 16 and 20 which is 4. Divide both by 4 to get 4:5.
