Answer:
698 apples
Step-by-step explanation: 78*9 equals 702. She sold 4 less than that so you need to subtract 4. 702-4=698 apples Berta sold.
If you are trying to find the degree of f(-4) the answer is 1.
Answer:
The stone will be in flight for 3 seconds
Step-by-step explanation:
Given the equation;
d = -16t^2 + vt + h
Where;
v = the initial velocity
h = the initial height
Given;
v = 48 ft/s
h = 0
Substituting into function d;
d = -16t^2 + 48t + 0
d = -16t^2 + 48t
At the point of launch and the point of landing d = 0.
We need to calculate the values of t for d to be equal to zero.
d = -16t^2 + 48t = 0
-16t^2 + 48t = 0
Factorising, we have;
16(-t+3)t = 0
So,
t = 0 or -t+3 = 0
t= 0 or t =3
Change in t is;
∆t = t2 - t1 = 3 - 0
∆t = 3 seconds.
The stone will be in flight for 3 seconds.
Well you can use the Pythagorean Theorem Formula a
+b
=c
. Just plug in the first 2 least numbers into a and b, and see if your answer(c) is equal to the last number. Hope I helped!
