Answer: B, 5.5
Step-by-step explanation:
4+4+4+5+5+6+6+6+6+9=55
55/10=5.5
Factor out the common term; 3
(3(x + 1))^2 = 36
Use the Multiplication Distributive Property; (xy)^a = x^ay^a
3^2(x + 1)^2 = 36
Simplify 3^2 to 9
9(x + 1)^2 = 36
Divide both sides by 9
(x + 1)^2 = 36/9
Simplify 36/9 to 4
(x + 1)^2 = 4
Take the square root of both sides
x + 1 = √4
Since 2 * 2 = 4, the square root of 2 is 2
x + 1 = 2
Break down the problem into these 2 equations
x + 1 = 2
x + 1 = -2
Solve the first equation; x + 1 = 2
x = 1
Solve the second equation; x + 1 = -2
x = -3
Collect all solutions;
<u>x = 1, -3</u>
The y intercept is where the line hits the verticals line of the graph. Hope this helps!
Answer:
The average rate of change of the function over the interval is 5.
Step-by-step explanation:
Average rate of change of a function:
The average rate of change of a function f(x) over an interval [a,b] is given by:
Interval -3 less-than-or-equal-to x less-than-or-equal-to 3
This means that 
So
Average rate of change
The average rate of change of the function over the interval is 5.
Respuesta:
30,6 metros
Explicación paso a paso:
Dado :
Presión = 300 Kpa
Usando la fórmula que relaciona la presión y la profundidad:
Presión = profundidad * aceleración debida a la gravedad * densidad del agua
Densidad del agua = 1000 kg / m³
Presión = 300Kpa = 300 * 10 ^ 3 Pa
300 * 10 ^ 3 Pa = profundidad * 9,8 * 1000
300000 = profundidad * 9800
Profundidad = 300000/9800
Profundidad = 30,612
Profundidad = 30,6 m
