Answer:
We choose B. (1, 10)
Step-by-step explanation:
Given the exponential model in the form y = a
- passes through the points (2, 50)
<=> 50 = a
<=> a = (1)
- passes through the points (3, 250)
<=> 250 = a (2)
Substitute (1) into (2) we have:
250 =
<=> 50b = 250
<=> b = 5
=> a = = 2
Hence, our exponential model is: y =2*
Let analyse all possible answer:
A. (0, 5) we have: y =2* ≠ 5 so it is wrong
B. (1, 10) we have: y = 2* so it is true
C. (4, 450) we have: y = 2* ≠ 450 so it is wrong
D. (5, 650) we have: y = 2* ≠ 650 so it is wrong
Hence we choose B. (1, 10)
Answer:
18 5/12 is the answer.
Step-by-step explanation:
Answer:
looking at this picture i see that the x value is -30 and the y value is 30
and looking at this it looks like the slope is 30°.
Step-by-step explanation:
not sure if this is right because i have a blank memory about things i learned in pre alg.
but if i'm wrong forgive me.
and if i'm right good luck on whatever you are doing.
We can sum two fractions if they have the same denominator, so we have to rewrite both fractions so that they'll have the same denominator.
We can generate equivalent fractions by multiplying both numerator and denominator by the same number.
So, we have
Similarly, we have
Now we can sum the fractions:
ln(2e/x)
ln2+ ln e -ln x
ln 2 + 1 - ln x
OPTION D is the correct answer
