Answer:
around 4.1
Step-by-step explanation:
Answer:
The arrow is at a height of 48 ft after approximately <u>0.55</u> s and after <u>5.45</u> s
Step-by-step explanation:
The following information is missing:
<em>The height of an arrow shot upward can be given by the formula s = v0*t - 16*t², where v0 is the initial velocity and t is time.How long does it take for the arrow to reach a height of 48 ft if it has an initial velocity of 96 ft/s? </em>
If the arrow is at a height of 48 ft and its initial velocity is 96 ft/s, then:
48 = 96*t - 16*t²
16*t² - 96*t + 48 = 0
16*(t² - 6*t + 3) = 0
t² - 6*t + 3 = 0
t² - 6*t + 3 + 6 = 0 + 6
t² - 6*t + 9 = 6
(t - 3)² = 6
t - 3 = √6
t - 3 = 2.45; t = 2.45 + 3; t = 5.45
or
t - 3 = -2.45; t = -2.45 + 3; t = 0.55
Answer:
x=0 x=2 x=7/2
Step-by-step explanation:
P(x) = 3x (x - 2) (2x - 7)
Set equal to zero
0 = 3x (x - 2) (2x - 7)
Using the zero product property
3x =0 x-2 =0 2x-7 =0
x=0 x=2 2x=7
x=0 x=2 x=7/2
Answer:
D
Explanation:
Same x values cannot correspond to any y values. Also if u plotted the points, the vertical line test would fail.
Answer:
D. 105
Step-by-step explanation:
500-270, there's 230 total 2 head.
270-100 of one head, is 170 purple one head. 170+125 purple equals 295.
296 subtract from 500 total is 205 for total green.
205-100, 105 2 head.
