There are 310 tens in 3100.
145 = -16 t² + 80 t +s
s = ?
v = v0 - at
0 = 80 - at
80 = at
s = 80 t - at²/2
s = 80 t - 80t/2
s = 40 t
Finally: 145 = -16 t² + 80 t + 40 t
16 t² - 120 t + 145 = 0
We will solve this quadratic equation:
t = [120 +√ ( (-120)²- 4 · 16 · 145 )] / 32
t = [120 + √ (14400 - 9280) ] / 32
t = (120 + 71.55) / 32 = 5.98 ≈ 6 s
Answer:D) 6 seconds
Answer:
f(x) = (x - 4)^2
Step-by-step explanation:
When plotted upon a graph, the function passes through the line. You can find the vertex by using the formula: f(x) = a(x - h)^2 + k
h = 4, meaning the vertex is (4, 0)
Hope this helps!
Knowing that it is a quarterly rate, we know that there are 20 quarters in 5 years:
20(1.05(x)) = 7500
21x = 7500
x = 357.14
You should deposit about $357.14
Answer:
24 inches
Step-by-step explanation:
a square has 4 equal sides. if one side is 6, the rest of the sides are also six. perimeter is all the sides added. so 6+6+6+6, or 6*4, equals 24 inches as perimeter.
