Answer:
6
Step-by-step explanation:
Let . We know the formula for the sum of an arithmetic sequence is:
Where n is the number term you are finding the sum up to, a1 is the first term, and an is the nth term. We can substitute what we have:
The formula to find the nth term of an arithmetic series is:
Where d is the common difference. Again, we can plug in what we have;
B is the answer as when you draw angle bisector you draw arcs that intersect at the bisector
2)use the formula y2-y1/x2-X1
3)is (A)
Answer:
y=-5/2x+7
Step-by-step explanation:
y=mx+b (slope intercept form)
y-2=-5/2(x-2)
y-2=-5/2x+10/2
y-2=-5/2x+5
y=-5/2x+5+2
y=-5/2x+7
The number of second it takes the apple to hit the ground is 4 seconds
To answer the question, we need to know what functions are
<h3>What are functions?</h3>
Functions are mathematical equations that show the relationship between two variables
Given that when an apple is dropped from a tower 256 feet high, the function h(t) = -16t² + 256 modelshe height of the apple, in feet, after t seconds.
<h3>Time it takes the apple to hit the ground</h3>
The time it takes the apple hits the ground is when h(t) = 0
So, h(t) = 0
-16t² + 256 = 0
-16t² = -256
t² = -256/-16
t² = 16
t = ±√16
t = ±4
Since t ≥ 0, t = 4 seconds
So, the number of second it takes the apple to hit the ground is 4 seconds
