Answer:
-0.67
Step-by-step explanation:
Pick two points on the tangent line, and find the slope between them.
The line passes through approximately (30,145) and (90, 105).
m = (105 − 145) / (90 − 30)
m = -0.67
Y = mx+c
m is the gradient and c is the y-intercept so
4 = m(4) + (-4)
4 = 4m - 4
4m = 8
m = 2
Ans: Y = 2x - 4
Answer:
The number of bacteria grown in 35 hours is 15771
Step-by-step explanation:
It is given that,
Researchers recorded that a group of bacteria grew from 100 to 7,000 in 14 hours.
Therefore, the bacteria has grown from 100 to 7000 in 14 hours.
To calculate number of bacteria grown in 14 hours :
⇒ 7000 - 100 = 6900
6900 bacteria grows in 14 hours. We need to find out the growth of bacteria in 1 hour in order to calculate its growth in 32 hours.
To calculate number of bacteria grown in 1 hour :
⇒ Total bacteria growth in 14 hours / 14
⇒ 6900 / 14
⇒ 492.85
To calculate number of bacteria grown in 32 hours :
⇒ 492.85 × 32
⇒ 15771.2
⇒ 15771 (rounded to nearest whole number)
∴ The number of bacteria grown in 32 hours is 15771
Hope this answer helps you :)
