Answer:
(1). 8
(2). 8
(3). 8
(4). 8
Step-by-step explanation:
Statement (1).
The domain of this graph is [0, 10]
True.
(x-values or input values of the function is a set of values between 0 and 10 including 0 and 10 both)
Statement (2).
The Range of this graph is {3, 7, 9, 12}.
True.
(For input values x = 0, 4, 9, 10 there is a distinct output value y = 3, 7, 9, 10
Statement (3).
This graph represents continuous data.
True.
Since this graph has a distinct value of y for every value of x and the graph is not interrupted.
Therefore, it's a continuous function.
Statement (4).
The graph represents a function.
True.
For every value of x (input value ) a distinct value of y (output value) is obtained.
Therefore, graph represents a function.
All i got is (3,8) (2,5) and (2,-6)
Answer: 57.27
Step-by-step explanation:
using the proportion we have x= (5*126)/11= 57.27
Answer: (2x-1) (2x-3)
Step-by-step explanation:
Answer:
x =-5± 2i sqrt(14)
Step-by-step explanation:
x^2 + 10x= -81
Take the coefficient of x and divide by 2
10/2 = 5
Square it
5^2 =25
add to each side
x^2 + 10x+25 = -81+25
( x+5) ^2 = -56
Take the square root of each side
sqrt(( x+5) ^2) =± sqrt(-56)
x+5 = ± sqrt(-1) sqrt(4*14)
x+5 =± i sqrt(4)sqrt(14)
x+5 =± i 2 sqrt(14)
Subtract 5 from each side
x+5-5 =-5± i 2 sqrt(14)
x =-5± 2i sqrt(14)
