The least common factor is 2.
2*18=36 2*24=48
A ) This is a quadratic function:
y = a x² + b x + c
If the starting point is ( 0, 0 ) then c = 0
b ) The function is:
y = - 0.2 x² + 3.6 x
( with coefficients to the nearest tenth )
The graph is in the attachment.
c ) The roots:
x 1 = 0,
0.2 x = 3.6
x = 3.6 : 0.2
x 2 = 18d ) This is near the target ( 17 m ) . So the pumpkin
will hit near the target.
X² + y² - 4 x + 2 y = b
x² - 4 x + 4 + y² + 2 y + 1 = b + 4 + 1
( x - 2 )² + ( y + 1 )² = b + 5
y - coordinate of the center of the circle is: y = - 1
b + 5 = r
b + 5 = 7
b = 7 - 5
b = 2
Answer:
15
Step-by-step explanation:
What is average/arithmetic mean?
It means the "sum of the numbers" divided by the "number of numbers".
Let the two numbers be "x" & "y"
It says, average of 2 numbers is 12, so we can write:
Smaller number is 6 less than bigger number. Let's suppose x is the bigger one and y is the smaller one, so we can write:
x - 6 = y
Now we have 2 equations:
x + y = 24
x - 6 = y
Putting 2nd in 1st we get:
x + x - 6 = 24
Solving for x:
2x - 6 = 24
2x = 24 + 6
2x = 30
x = 30/2
x = 15
Now we know y = x - 6, so
y = 15 - 6 = 9
y = 9
The larger number is 15
Answer:
Minimum hour = 177 hour
Step-by-step explanation:
Given:
Paddle boats rent = $8
Paddles rent = $5 Per 24 hours
Total amount = $45
Find:
Number of hour David rent paddle boat
Computation:
8 + (5/24)n = 45
(5/24)n = 37
n = 177.6 hour
Minimum hour = 177 hour
