Answer:
Option c. All real numbers except
Step by step explanation:
The first thing we must do is divide the function between the function
Note that both the domain of f(x) and the domain of g(x) are all reals, since they are polynomial functions.
However, remember that the division between zero is not allowed. Therefore now the domain of f(x)/g(x) are all values of x for which the denominator is nonzero. Therefore we must find the values for which g(x) = 0
Finally the domain of f/g are all real numbers except
The little rectangle in the top right means the angle is a right angle which equals 90 degrees.
This also means all the other angles are also 90 degrees.
Solve for x:
2x+8 = 90
Subtract 8 from both sides:
2x = 82
Divide both sides by 2:
x = 82/2
x = 41
Area of central park = 2.5 × 0.5 = 1.25 square mile
1 acre = 1/640 square mile
1.25 square mile = 1.25 ÷ 1/640 = 800 acre
Number of people in the park = 800 ÷ 15 = 53.3 ≈ 53 people
Answer:
1. 5x+10y=35 x= 5 y= 1
2. 2x+12y=30 x= 3 y= 2
Step-by-step explanation:
1. 5x+10y
10+5=15; 15-10=5; x=5
10/5=2; 2/2=1; y=1
5(5)=25
10(1)= 10
25+10= 35
YAY!
2. 2x+12y
12/2=6; 6/2=3; x=3
12/6=2; y=2
2(3)=6
12(2)=24
24+6= 30
YAY!
Answer:
That's the exponential function.
Step-by-step explanation:
Simply just use a graphing calculator (there's plenty of apps and websites that are graphing calculators) and follow these steps.
1) Clear out calculator RAM
2) Press STAT button
3) Press ENTER on EDIT
4) Type the X's in L1 and type the Y's L2.
5) Press STAT again
6) Press the RIGHT ARROW once
7) Press 0
8) Press ENTER
9) There's your exponential function!
