Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000
Growth rate = r = 150% = 1.50
The equation model for this situation is:
Using the values in above equation, we can write:
This means, the person will fall sick after about 14 hours.
Answer:
5 and -5 (±5)
Step-by-step explanation:
x²-8=17
x²=25
√x²=√25
x=±5
Since AB=AD, the triangle on the left is isosceles and has two 35 degree angles. Since the sum of all the interior angles is 180 deg,
x = 180 deg - 2(35 deg) = 110 deg (answer)
Answer:
The matched options to the given problem is below:
Step1: Choose a point on the parabola
Step2: Find the distance from the focus to the point on the parabola.
Step3: Use (x, y).
Find the distance from the point on the parabola to the directrix.
Step4: Set the distance from focus to the point equal to the distance from directrix to the point.
Step5: Square both sides and simplify.
Step6: Write the equation of the parabola.
Step by step Explanation:
Given that the focus (-1,2) and directrix x=5
To find the equation of the parabola:
By using focus directrix property of parabola
Let S be a point and d be line
focus (-1,2) and directrix x=5 respectively
If P is any point on the parabola then p is equidistant from S and d
Focus S=(-1,2), d:x-5=0]
Answer:
He hit 552 home runs in 12 years
Step-by-step explanation:
To solve this problem, we will follow the steps below;
Using proportion;
Let x be the number of home runs he hits in 12 years
46 home runs = 1 year
x = 12
cross -multiply
x × 1 = 46× 12
x = 552 home runs
Therefore, he hit 552 home runs in 12 years
