Answer: 18x+16 cm
Step-by-step explanation:
Combine the like terms. 9x+9x = 18x and 8+8=16
Answer:
{ln 4, (2 + 2e^ln 4 − 4 ln 4)} or (1.39, 4.45)
Step-by-step explanation:
From this equation 4x − y = 3
-y = 3 - 4x
then, y = 4x - 3
From line equation y = mx + b
Therefore, the slope is 4
Since the are parallel line, they will have same slope
Finding the derivative of y = 2 + 2e^x − 4x
y = 2 + 2e^x − 4x
y' = 0 + 2e^x - 4
Therefore,
4 = 2e^x - 4
4 = e^x
x = ln 4 = 1.39
To find the y coordinate
y = 2 + 2e^x − 4x
y = 2 + 2e^ln 4 − 4 ln 4
y = 4.45
Hence, they are parallel at point (1.39 and 4.45)
You would solve this by finding the slope. The wrestler would have started at month 0. The slope formula is y1-y2/x1-x2. We are going to use the first two numbers for the slope,
93.6-85.8/3-1.5 Then we simply the equation.
7.8/1.5
5.2
This means that each month and a half. He gains 5.2 kilograms. So, we would subtract this from the first number in our table. 85.8-5.2=80.6
The wrestler was 80.6 kilograms when he started his diet
The answer is 0.069444444444
