Answer:
x =1
y = 2
z = -1
Step-by-step explanation:
I Hope it helps. Please if you need any clarification, let me know .
Given that the bacteria has been modeled by the function:
r(t)=(450.267)e^(1.12567t)
thus the number of bacteria after 3 hours will be:
r(3)=450.267e^(1.12567×3)
r(3)=13,185.20623
The number of bacteria after 3 hours will be:
13, 185.20623
r = 255
r = R-2RF/W
R = 1,750
F = 63.2
W = 148
Now, we need to plug the values in to substitute the variables with real numbers.
r = 1750-2(1750 x 63.2)/148
First, solve for the parentheses.
r = 1750-2(110600)/148
Second, multiply by 2.
r = 1750-221200/148
Next, divide by 148.
r = 1750 - 1494.594
Then, we subtract.
r = 255.406
Lastly, we round it to the nearest whole number.
r = 255
Answer:
Perimeter: 26.43 m
Area: 27.99 sq m
Step-by-step explanation:
To find the perimeter we just add all the sides, 11.1+9.33+6 = 26.43
To find the area of a triangle, we use the formula we do (bh)/2
9.33 * 6 = 55.98
55.98 / 2 = 27.99
