Answer:
C. AB = 5.8 cm
Step-by-step explanation:
In trapezoid ABCD, EF is the Midsegment.
.:. EF = {(AB+CD)
.:: 9.2 = {(AB + 12.6)
:: 9.2 x 2 = AB + 12.6
.. 18.4 = AB + 12.6
.. 18.4-12.6 = AB
:: AB = 5.8 cm
Answer:
C
Step-by-step explanation:
g(x) = 4x²
g(x) is steeper than f(x) and the ordered pair (1, 4) fits in option C:
g(1) = 4(1)² = 4
Answer:
Exponential
Step-by-step explanation:
<em>Starter:</em>
According to the title:
"Every day, half a bacteria population dies."
Exponential: y = ab^x ( b > 0 , b ≠ 1)
So the answer is C.
<em>Calculations:</em>
An exponential model is of the form y = a • b^t.
If you start with population of 500 million bacteria
t = 0
so 500 million = a • b^0 = a
Since every day half the population dies then in 1 day population will be 250 million
so a = 500 million, y = 250 million and t = 1
250 million = 500 million • b^1
b = 0.5
Therefore your equation would be
y = 500 million (or whatever the pop) • 0.5^t
Where t = number of days
This could also be written in exponential form ( e = 2.73)
The data set has no association.
