Answer:
110.9 feet
Step-by-step explanation:
The function that models the flight of the ball is
where f(x) is the vertical distance in feet and x is the horizontal distance the ball travels
If the ball hits the ground, then f(x)=0
The solution is given by the quadratic formula:
We substitute a=-0.02, b=2.2, and c=2 to get:
This implies that:
Since we are dealing with time,
To one decimal place, we have 110.9 feet
Answer:
Divide both the numerator and denominator by the GCD
Step-by-step explanation:
Answer:
Step-by-step explanation:
The real part does not have i as a multiplier. It is 23.3.
The imaginary part* is the coefficient of i: 44.
_____
* There is some disagreement as to whether the imaginary part includes i or not. One source says the imaginary part is the part that has i as a factor (44i). Another source says the imaginary part is the real number that multiplies i (44). Above, we have used the latter definition. Please consult your curriculum materials for the definition you should use.
Answer:
Total mixture = (8x + 15y) / 100
Step-by-step explanation:
Butterfat x:
= 8% of x
= 8/100 * x
= (8 * x) / 100
= 8x / 100
Butterfat y:
= 15% of y
= 15/100 * y
= (15 * y) / 100
= 15y / 100
Total mixture = butterfat x + butterfat y
= 8x / 100 + 15y / 100
= (8x + 15y) / 100
Total mixture = (8x + 15y) / 100
