The sum(9) of half of the first number(1/2a) and one third of the second number(+1/3b)
That is correct
Answer:
d. $43.00
Step-by-step explanation:
Karli's total cost is ...
total cost = material cost + labor cost
= ($8.00/10 gal)·(5 gal) + ($13.00/h)·(3 h)
= $4.00 + $39.00
= $43.00
D is correct because the 48 quart * 4cup/1quart*8ounce/1Cup=1536 fl .oz
Problem
For a quadratic equation function that models the height above ground of a projectile, how do you determine the maximum height, y, and time, x , when the projectile reaches the ground
Solution
We know that the x coordinate of a quadratic function is given by:
Vx= -b/2a
And the y coordinate correspond to the maximum value of y.
Then the best options are C and D but the best option is:
D) The maximum height is a y coordinate of the vertex of the quadratic function, which occurs when x = -b/2a
The projectile reaches the ground when the height is zero. The time when this occurs is the x-intercept of the zero of the function that is farthest to the right.
•Using the formula the first term is a1 = −3
•Using the formula the second term is a2 = −1
•Using the formula the third term is a1 = 6
•Common difference formula:
a2 - a1 = (-1) - (-3) = 2
