Answer:
8
Step-by-step explanation:
m=30 n=1/4
0.1*30+8-12*1/4
3+8-12*1/4
=3+8-3
=8

Answer:
<em>The diver's depth will be -42.9 after 30 minutes</em>
Step-by-step explanation:
The equation of the trend (or best fit line) for the scuba diver's depth in the ocean is:
y = -3.29x - 10
Where y is the diver's depth and x is the time in minutes.
To predict the diver's depth at x=30 minutes, substitute in the equation:
y = -3.29(10) - 10
y = -32.9 - 10
y = -42.9
Since no units are provided for y, the answer is:
The diver's depth will be -42.9 after 30 minutes
You need to subtract everything to the left side and set it equal to zero. Combine like terms.
Then, the coefficient of x^2 is a, the coefficient of x is b, and the constant term is c.
4x^2 - 5 = 3x + 4
4x^2 - 3x - 5 - 4 = 0
4x^2 - 3x - 9 = 0
a = 4; b = -3; c = -9
Answer:
(x-2)²+(y-4)²=4
