Just simply multiply then after you multiply you get: 36156
Now since you have 3 decimal places you put the decimal point three times to the left and you get.....
36.156
I hope this helps!
Answer:
5
Step-by-step explanation:
if you add $1.50 +50 cents its $2.00 count by 2's until you get
to 10 and thats 5 how i got 50 cents 25 cents for a half mile
25+25 is 50.
<span>(3x^3-4x^2-5x+3)+(-4 - 6x^3+x^2 - 5x+5)
= </span><span>3x^3 - 4x^2 - 5x + 3 - 4 - 6x^3 + x^2 - 5x + 5
= -3x^3 - 3x^2 - 10x + 4</span>
Answer:
the rate from the plane to the radar station increasing 3 minutes later is 19.81 km/min
Step-by-step explanation:
A plane flying with a constant speed of 14 km/min passes over a ground radar station at an altitude of 4 km and climbs at an angle of 45 degrees. At what rate is the distance from the plane to the radar station increasing 3 minutes later?
speed (Δs₁)= change in distance(Δd₁) /(Δt₁)change in time
mathematically,
= Δs₁
= 14 km/min = 
and will are to find the speed after passes the radar
=Δs₂ km/min = 
to find d₁ and d₂ with respect to angle 45 degree at 4km
sin 45 = opp/hyp = 4/d₁
d₁ = 4/sin45 = 5.66km
tan 45 == opp/adj = 4/d₂
d₂ =4/tan45 = 4km
for three minute increment,
=3 x d₁ x Δs₁ = 3 x d₂ Δs₂
= 3x5.66x14 = 3x 4 xΔs₂
= 237.72 = 12Δs₂
=Δs₂ = 19.81km/min
Answer:

Step-by-step explanation:
parabola equation with vertex (0 , 0) and focus length |f| = 7
4*f*(x - h) = (y - k)²
4*7*(x-0)=(y-0)²
28x = y²
