Answer:
3x^2+1.5x-9
Step-by-step explanation:
(f+g) (x)
=f(x)+g(x)
=x/2-3+3x^2+x-6
=3x^2+1.5x-9

Answer:
Speed of Amy is 3.75 miles per hour.
Step-by-step explanation:
We have, speed of Amy = 110 yards per minute
This means, she covers 110 yards of distance in 1 minute.
Now, to convert the speed of Amy into miles per hour, we will first convert the distance from yards into miles and then convert time from minutes to hour.
We know that,
1 yard = 3 feet
∴ 110 yards = 3 × 110 feet = 330 feet
Now, we also know that,
5280 feet = 1 mile
∴ 1 feet =
miles
So, 330 feet =
=
miles
∴ 110 yards = 330 feet =
miles
Now, 60 min = 1 hr
∴ 1 min =
hrs
So, 110 yards =
miles and 1 min =
hr
So, we can say that, Amy covers a distance of
miles in
hr.
We know that,



Therefore, the speed of Amy in miles/hr is 3.75 miles/hr.
Tan(29°) = opposite/adjacent = AC/CB ⇒
CB = AC/tan(29°) = 20/0.5543 ≈ 36.08
sin(29°) = opposite/hypotenuse = AC/AB ⇒
AB = AC/sin(29°) = 20/0.4848 ≈ 41.25
∠A = 180 - ∠B - ∠С = 180 - 29 - 90 = 61°
