Answer:
Step-by-step explanation:
What you have here is the factored form of the quadratic
where a is the term representing the pull of gravity, b is the upwards vertical velocity and c is the initial height. If we FOIL that out, we get the equation in a form that is easily analyzed for velocity and initial height.
This tells us that the initial vertical velocity of the dive was 10 m/sec, and that she was 15 meters up at the time of diving.
Any rational number that is -9 up (-10, -11, -12, etc.) is an integer less than -8
To find the value of Coach Velez's total bill, first we must figure out how much the total of all of the ice cream sundaes were.
To do this, we must multiply the number of sundaes (8) by the cost of each sundae ($5.35).
8 * 5.35 = $42.80
However, Coach Velez also left a tip of 15%. To find out how much Coach Velez tipped, we have to multiply his regular bill ($42.80) times the amount he is tipping (15% or 0.15)
$42.80 * 0.15 = $6.42
Finally, we just have to add the bill ($42.80) and the tip ($6.42) together to find Coach Velez's total amount.
$42.80 + $6.42 = $49.22
Coach Velez spent $49.22 in all.
I think the answer would be D.
Answer:
47.856
Step-by-step explanation:
We will use
SOH
CAH
TOA
to solve this
we have the adjacent length, but need the hypotonouse
which means that we will use CAH
we have
cos(43)= 35/p
solve for p
47.856
