Answer:
Below in bold.
Step-by-step explanation:
x-intercepts (-3,0) and (6, 0)
y-intercept (0, -5)
Axis of symmetry:
(-3 + 6) / 2 = 1.5
x = 1.5.
Domain = all real x.
Range is f(x) ≥ -6.
Graph is positive for x < -3 and x > 6.
Negative for -3 < x < 6.
Increasing for x > 1.5 and decreasing for x < 1.5.
Answer:
height: 125m; distance: 500m
Step-by-step explanation:
x = 250
f(x) = x − 0.002x2
f(x) = 250 − 0.002(250 )2
= 250 − 0.002(62,500)
= 250 − 125
= 125
250 times 2 = 500

Answer:
Step-by-step explanation:
Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test reults
µ = mean score
σ = standard deviation
From the information given,
µ = 1700 points
σ = 75 points
We want to the probability that a student will score more than 1700 points. This is expressed as
P(x > 1700) = 1 - P(x ≤ 1700)
For x = 1700,
z = (1700 - 1700)/75 = 0/75 = 0
Looking at the normal distribution table, the probability corresponding to the z score is 0.5
P(x > 1700) = 1 - 0.5 = 0.5
