The slope of a line is the amount of units it goes across the x axis by how many units it goes up the y axis. A line with slope 3 goes 3 spaces up for every one space along.
Final answer is...... positive 15/8
31.0 degrees
TanX wich is 30/50
same thing as 30 divided by 50
Answer:
A) 0.106
Step-by-step explanation:
8e^3x + 4 = 15
Subtract 4 from each side
8e^3x + 4-4 = 15-4
8e^3x = 11
Divide each side by 8
8/8e^3x = 11/8
e^(3x) = 11/8
Take the natural log of each side
ln(e^(3x)) = ln(11/8)
3x = ln(11/8)
Divide by 3
3x/3 = 1/3 ln(11/8)
x = 1/3 ln(11/8)
x =.106151244
To the nearest thousandth
x = .106
F ( x ) - the number of seats in the 1st row;
s ( x ) - the number of additional seats in the next row;
An equation that predicts the number of seats in any row:
g ( x ) = f ( x ) + s ( x )
g ( x ) = 12 + 3 ( x - 1 )
The number of seats in the 30th row:
g ( 30 ) = 12 + 3 * ( 30 - 1 ) = 12+ 3 * 29 = 12 + 87 = 99 seats
