Answer:
[ - 5, 3 ]
Step-by-step explanation:
Solve (x - 3)(x + 5) = 0
The zeros are x = - 5 and x = 3
These divide the domain into 3 intervals
(- ∞, - 5 ], [- 5, 3 ], [ 3, + ∞ )
Choose a test point in each interval and consider the sign of the result.
x = - 10 : (- 10 - 3)(- 10 + 5) = (- 13)(- 5) = 65 > 0
x = 0 : (0 - 3)(0 + 5) = (- 3)(5) = - 15 < 0 ← required result
x = 5 : (5 - 3)(5 + 5) = (2)(10) = 20 > 0
The solution is [ - 5, 3 ] or - 5 ≤ x ≤ 3
Answer: 448 hours
Step-by-step explanation:
272 divided by 17 = hourly wage
hourly wage= 16$
448 divided by 16 = 28 weeks
28 x 16= 448 hours
Answer:
22 square units.
Step-by-step explanation:
The missing image is attached.
We want to find the area of the figure shown in the attachment.
We can quickly calculate the area of the figure by counting the unit squares.
Counting from top row, we have: (6 +4+6+3+3) unit squares.
This simplifies to 22 unit squares.
The correct answer for that would be a circle, because a circle is perfectly symmetrical all the way around
