Answer:
his tip will be $3.21
Step-by-step explanation:
17.85 times 0.18
multiply and get 3.213
round that to $3.21
Answer:
(x+5)² = 16
Solution: -1 and -9
Step-by-step explanation:
Given the quadratic equation X^2+10x+22=13
Subtract 22 from both sides
X^2+10x+22-22=13-22
x^2+10x = -9
Complete the square
Add the square of half of coefficient of x to both sides
coefficient of x = 10
half of coefficient of x = 10/2 = 5
square of half of coefficient of x= 5² = 25
Add 25 to both sides
x²+10x + 25 = -9+25
(x+5)² = 16
Hence the required equation is (x+5)² = 16
(x+5)² = 16
square root both sides
√(x+5)² = √16
x+5 = √16
x +5 = ±4
x = +4 - 5 and -4-5
x = -1 and -9
Hence the solution to the equation is -1 and -9
Answer: Use the second one: 18 - x = 6
Answer: 64 ft
Step-by-step explanation:
We are given the following equation that models the baseball's parabolic path:
(1)
Where:
is the ball maximum height
is the time
is the initial height
With this information the equation is rewritten as:
(2)
Now, we have to find , and this will be posible with the following formula:
(3)
Where:
is the final velocity of the ball at the point where its height is the maximum
is the acceleration due gravity
Isolating :
(4)
(5)
(6)
Substituting (6) in (2):
(7)
Finally:
So you just want to say 36/18 or 2.
So it's 2, or 200%.
