Answer:
9 seconds
Step-by-step explanation:
When the object is on the ground it's height = 0
Equate h(x) = 0, hence
- 5(x + 1)(x - 9) = 0
equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x - 9 = 0 ⇒ x = 9
x > 0 hence x = 9
The object hits the ground 9 seconds after being launched
Answer:
y- intercept --> Location on graph where input is zero
f(x) < 0 --> Intervals of the domain where the graph is below the x-axis
x- intercept --> Location on graph where output is zero
f(x) > 0 --> Intervals of the domain where the graph is above the x-axis
Step-by-step explanation:
Y-intercept: The y-intercept is equivalent to the point where x= 0. 'x' is the input variable in an equation, therefore the y-intercept is where the input, or x, is equal to 0.
f(x) <0: Notice the 'lesser than' sign. This means that the value of f(x), or 'y', is less than 0. This means that this area consists of intervals of the domain below the x-axis.
X-intercept: The x-intercept is the location of the graph where y= 0, or the output is equal to 0.
f(x) >0: In this, there is a 'greater than' sign. This means that f(x), or 'y', is greater than 0. Therefore, this consists of intervals of the domain above the x-axis.
Answer:
A
Step-by-step explanation:
Because it’s the only sequence that have a common difference
P=25h +600
Total pay would be P, ot rate is $25, and his basic pay is $600.
h - would represent the ot hours that he works times the rate
