Answer:
Ann us correct. It's a quadratic function.
Step-by-step explanation:
Given equation is,
y = 3x(x - 7)
By converting this equation into the standard quadratic equation,
y = 3x² - 21x
Highest exponent of the polynomial equation is 2 (Exponent of highest degree variable x²). This decides that the given function is a quadratic function.
Therefore, Ann is correct. It's a quadratic function.
Answer:
The answer is G. y=2x-2
Step-by-step explanation:
y+6=2(x+2)
First you multiply 2 by what is in the parenthesis
y+6=2x+4
Next you get y by itself by subtracting 6
y=2x+4-6
Simplify
y=2x-2
A.
For this case, let us set the variables:
s = 0 (final destination on the ground)
t = unknown
vo = 0
so = 8000 ft
Using the equation, we calculate for t:
0 = -16 t^2 + 0t + 8000
t = 22.36 s
B.
For this case:
s = unknown
t = 22.36 s
vo = 600 miles/hr = 880 ft/s
so = 0
Using the equation, we calculate for s:
s = -16*(22.36)^2 + 880*22.36 + 0
s = 11, 677.29 ft = 2.21 miles

Answer:
<h3>0.8</h3>
Step-by-step explanation:
Given the formula for the geometric series expressed as;
The nth term of a geometric progression is expressed as;
a is the first term
r is the common ratio
Comparing both equations;
Hence the value of r of the geometric series is 0.8
