Answer:
Correct answer: y- intercept is 200 for time x = 0 sec
y = 200 · (3/2)ˣ
The population after x = 10 minutes is: y = 11,533
Step-by-step explanation:
We see from the diagram that the initial bacterial count is 200 which is y-intercept
The formula for an exponential function is:
y = 200· aˣ
to find the basis a we read the second point (1, 300)
300 = 200 · a¹ => a = 300/200 = 3/2
the exact formula is
y = 200 · (3/2)ˣ
we verify the accuracy of the formula using the third point (2, 450)
450 = 200 · (3/2)² => 450 = 200 · 9/4 => 450 = 50 · 9 => 450 = 450
The population after x = 10 minutes is:
y = 200 · (3/2)¹⁰ = 200 · 57.665 = 11,533
y = 11,533
God is with you!!!
Sin of an angle is opposite leg divided by hypotenuse.
sin B= 12 / 13
tan of an angle is opposite leg divided by adjacent leg
tan B= 12 / 5
cos of an angle is adjacent leg divided by hypotenuse
cos B= 5 / 13
Answer:
12x + 15 = 12x - 15
Step-by-step explanation:
-5x - 25 = 5x + 25
-25 = 10x + 25
-50 = 10x
-5 = x
12x + 15 = 12x - 15
15 = -15 ( No solution )
12x + 15 = 3(4x + 5)
12x + 15 = 12x + 15
12x = 12x
0 = 0 ( True for all x's )
7x + 21 = 21
7x = 0
x = 0
Answer:Maybe ffor the positive numbers you could use like 1,2,3,4,5,6,7,8, and 9. For the negitive number could be like -1,-2,-3,-4,-5. And zero could repersent the middle. Get it or no?
