Using a rain gauge, Gerry determined that 1/2 inch of rain fell during 3/4 of an hour.What is the unit rate of rainfall in inches per hour
Answer:
Step-by-step explanation:
Remark
f(x) = 9x^2 - 5x + 3 is given. The notation means that wherever you see and x on the right, you replace it with the x in the brackes on the left. f(3) is a direction, not anything you have to adjust or manipulate.
Solution
f(-3) = 9*(-3^2) - 5*(-3) + 3 (-(3))^2 = -3 * -3 = 9 two minuses make a +
f(-3) = 9*(-3)(-3) + 15 + 3 -3 times an operation of minus equals a +
f(-3) = 9 * 9 + 15 + 3
f(-3) = 81 + 15 + 3
Answer: f(-3) = 99
Answer:
10.25
Step-by-step explanation:
Unit price means per 1
71.75/7 = 10.25 each
Answer:
A) 90.32%
B) 90.11%
C) 81.546 miles per hour
D)77.93%
Step-by-step explanation:
Given data:
speed = 73.7 miles/hour
standard deviation = 4.77 miles /hour
a)
= P (z< 1.31)
= 0.90320 = 90.32%
b)
= P (-2.872< z< 1.31)
= P (z<1.31) - P(z<-2.87)
= 0.90320 - 0.00205
= 0.90115 = 90.11%
c) P(X <X) = 0.95
z = 1.645
x = 81.546 miles per hour
= P (z> -0.775)
= 0. 0.7793 = 77.93%
Answer:
y = 3
Step-by-step explanation:
Hello,
when x tends to
tends to 0 as 1/2 < 1
so the equation of the asymptote for this function is y = 3
