How do I solve this?

1 answer:

4 0

y = abˣ
20 = ab¹
20 = ab
b b
20/b = a

y = abˣ
4 = (20/b)b²
4 = 20b
20 20
¹/₅ = b

y = abˣ
20 = ¹/₅b¹
20 = ¹/₅b
¹/₅ ¹/₅
100 = b

y = abˣ
y = 100(0.2)ˣ

Suppose a jar contains 13 red marbles and 11 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same

Alisiya [41]

I’d say around 75% or less

This is just an assumption considering that there are more red than blue but only trumps blue by 2. Taking out those two, you’d be left with a 50% chance of getting red and/or blue marbles

Determine whether the improper integral converges or diverges, and find the value of each that converges.

Ksju [112]

Answer:converge at $I=\frac{1}{3}$

Step-by-step explanation:

Given

Improper Integral I is given as

$I=\int^{\infty}_{3}\frac{1}{x^2}dx$

integration of $\frac{1}{x^2}$ is - $\frac{1}{x}$

$I=\left [ -\frac{1}{x}\right ]^{\infty}_3$

substituting value

$I=-\left [ \frac{1}{\infty }-\frac{1}{3}\right ]$

$I=-\left [ 0-\frac{1}{3}\right ]$

$I=\frac{1}{3}$

so the value of integral converges at $\frac{1}{3}$

I do not know how to count following formula<br><br>x + 5 = 3

saw5 [17]

The x is going to be a negative number to get the 3. so start off minus 5 from plus 5 and minus five from the other side too. the positive 5 and the negative cancel out and then take it fromt here with three and the negative 5.
