Answer:
144
Step-by-step explanation:
f(4)=3*4^2
f(4)=12^2
12*12=144
Answer:
B
Step-by-step explanation:
Interior angles of a triangle = 180°
3x°+3x+10°+4x-30°=180°
10x°-20°=180°
10x°=180°+20°
10x°= 200°
10x°/10=200°/10
x°=20°
Ok
y=-0.04x^2+8.3x+4.3
when the rocket reaches the ground (when height=0, ie when y=0), then the rocket will land, find the x coordinate
set y=0
0=-0.04x^2+8.3x+4.3
use quadratic formula
if you have ax^2+bx+c=0, then
x=

a=-0.04
b=8.3
c=4.3
x=

x=208.017 or -0.516785
xrepresents horizontal distance
you cannot have a negative horizontal distance unless you fired and theh wind blew it backwards
therefor x=280.017 is the answer
208.02 m
Answer:
Result: $26.46
Steps:
$24.50 (increase) + 8% = $26.46
24.50 x (1 + 8%) = 24.50 x (1 + 0.08) = 26.46
I'm truly sorry if my math is incorrect.
Bye, have a great day/night :)
