Answer:
D) Vertex: (-2,-8); maximum
Step-by-step explanation:
y = -2x² - 8x - 16
The negative on the first term tells us that the vertex will be a maximum
vertex occurs when the derivative is set to zero
y' = -4x - 8
0 = -4x - 8
8 = -4x
x = -2
y = -2(-2)² - 8(-2) - 16
y = -8 + 16 - 16 = -8
<em><u>Total Cost : 1800</u></em>
<u><em>12 dollars * 16 hours = 192 dollars earned</em></u>
<u><em>0.2 percent * 192 = 38.4 dollars saved</em></u>
A.<u><em>She earns 192 dollars every week</em></u>
B. she will save <em><u>38.4 dollars * 7 weeks = 268.8 </u></em> dollars in a week.
C. 7 days times 4.3 weeks = 30.1 days. <em><u>30.1 days * 38.4 = 1,155.84 dollars every month.</u></em>
D. it will take her about <em><u>2 months</u></em> to save the money. <em><u>To be exact: 1.6 months.</u></em>

Answer:
65
Step-by-step explanation:
You substitute the x in 10x with 6 so you have 10x6+5. So you multiply 10x6 and you add 5 and you get 65
