The midpoint is 15 hope i helped
Answer:
4
Step-by-step explanation:
To find the rate of change for the increase (warm up), use the coordinate pair of any two points on the line that slopes upwards in the graph.
Let's use the following:
At 5 mins (x), heart beats (y) is 80 => (5, 80)
At 10 mins (x), heart beats (y) is 100 => (10, 100)
Rate of change = 
Rate of change is 4.
Answer:
0.17
Step-by-step explanation:
The function can be rewritten as ...
B(t) = 9300·((1/2)^6)^t = 9300·(1/2)^(6t)
In order to multiply the number of bacteria by 1/2, the value of the exponent 6t must be equal to 1:
6t = 1
t = 1/6 ≈ 0.166667 ≈ 0.17
The culture loses half its size every 0.17 seconds.
Answer:
Step-by-step explanation:
k (porportionality)=y/x
our point on the graph is (4,3) so our constant of porportionality is 3/4
We know, S = n/2 [ a + l ]
Here, a = 45
l = 108
Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64
Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896
In short, Your Answer would be 4896
Hope this helps!
