Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 3ˣ + 10x
g(x) = 2x - 4
<u>Step 2: Find</u>
- Substitute in function values: (f - g)(x) = 3ˣ + 10x - (2x - 4)
- [Distributive Property] Distribute negative: (f - g)(x) = 3ˣ + 10x - 2x + 4
- Combine like terms: (f - g)(x) = 3ˣ + 8x + 4
Answer:
The number of chicken and cows should be 19 and 11.
Step-by-step explanation:
The number of chicken and cows should be 19 and 11.
Given that,
The farm has 30 chickens and cows, and there are 82 chicken and cow legs all together.
Let x represent the number of chickens in the farm.
Let y represent the number of cows in the farm.
Based on the above information, the calculation is as follows:
x + y = 30
Since a chicken has 2 legs and a cow has 4 legs.
So,
2x + 4y = 82 - - - - - - - - - - - - 1
Now
Substituting x = 30 - y into equation 1, it becomes
2(30 - y) + 4y = 82
60 - 2y + 4y = 82
- 2y + 4y = 82 - 60
2y = 22
y = 11
Now
x = 30 - 11
= 19
Answer:
Percentage of light that penetrates at 150 m will be 0.94%.
Step-by-step explanation:
By using logarithmic regression calculator,
Equation of the regression line will be,
y = 104.5173 - 20.6711(lnx)
Where x represents the depth of the ocean
And y will represent the penetration of light
Therefore, at the depth of 150 m, penetration of the light will be,
y = 104.5173 - 20.6711[ln(150)]
= 104.5173 - 103.5753
= 0.9420
≈ 0.94 %
Therefore, percentage of light that penetrates at 150 m will be 0.94%.
Karen has more of her drink left
This is because she has 1/6 of her drink left,while Michelle has 2/16, or 1/8 of her drink left.
Since 1/6> 1/8, Karen has more of her drink left
Hope this helps :)
