Answer:
(3,1)
Step-by-step explanation:
y=-4x^2+24x-35
x-intercept of the vertex formula:
v=-b/2a
a=-4
b=24,
c=-35
v = - 24/2(-4)
v = -24/-8
v = 3
substitute x as v
y= -4(3)^2 + 24(3) - 35
y= -4(9) + 72 - 35
y = -36 +72 - 35
y = 36 - 35
y = 1
therefore the vertex is
(3,1)
(1/4ab)^-2
Remove negative exponent by rewritten the equation as (4ab)^2
AUse Product rule to get:
4^2a^2b^2
Now raise 4 to the second power to get:
16a^2b^2
The last answer is correct.
The answer is the second answer choice, an = -13 + 5(n - 1)
Answer:
83 %
Step-by-step explanation:
If 5 out of 30 got an A, that means that
30 -5 = 25
25 out of 30 did not get and A
25/30 = .8333333 = 83.33333 %
Rounding to the nearest whole percent
83 %
