2.3+w>18. This is most likely the correct answer
Answer:
<u>400,000</u>
Step-by-step explanation: 3,000,000+400,000+90,000+3,000+500+80+4= 3,493,584.
The coefficient of n is 1
Answer:
Graph A
Step-by-step explanation:
The inequality reads "y is greater than negative one half." The > sign tells us that the arrow will point to the right. There is no line under the > sign, so the circle will be open. Graph A fits this criteria.
Answer:
C) 6.9 seconds
Step-by-step explanation:
h = -16t² + 96t + 100
When the ball hits the ground, h = 0.
0 = -16t² + 96t + 100
0 = 4t² − 24t − 25
Solve with quadratic formula:
t = [ -b ± √(b² − 4ac) ] / 2a
t = [ -(-24) ± √((-24)² − 4(4)(-25)) ] / 2(4)
t = [ 24 ± √(576 + 400) ] / 8
t = (24 ± √976) / 8
t = (24 ± 4√61) / 8
t = (6 ± √61) / 2
t = -0.91 or 6.9
Since t must be positive, t = 6.9 seconds.
