Answer:
the new equation is f(x)=x^2-4
vertex- (0,-4)
zeros- (-2,2)
y-intercept- (-4)
and it has a minimum
Answer:
t= 52 seconds
A= 7,903 ft
Step-by-step explanation:
So start by writing each plane as an expression.
Plane A
3687+65.5*t is an expression for the ascent
Plane B
5000+40.25*t is an expression for the ascent
to find the time when they are at the same altitude set them equal to each other
3687+65.5*t = 5000+40.25*t
25.25*t = 1313
t= 52 seconds
to find the altitude solve one of the expressions with t=52
A =3687+65.5*52= 7093 ft
Answer:
α = 27.9794744° ≈ 28.0 m (nearest tenth)
Step-by-step explanation:
Step 1:
Opposite (O) = 42.5 (the side opposite to the reference angle, α)
Adjacent (A) = 80
Hypotenuse (H) = the longest side opposite to the right angle
2. We are given the adjacent (A) and opposite (O) lengths, we would use TOA. Which is:
Tan α = Opp/Adj
Plug in the values
Tan α = 42.5/80
3. Make α stand alone
α = 
4. α = 27.9794744° ≈ 28.0 m (nearest tenth)
Answer:
y = 5/4 x
Step-by-step explanation:
We already know the slope, so now we need to find the y-intercept. To do that, you need to simply plug the coordinates into the equation which is
y = 5/4 x + b
-5 = 5/4 (-4) + b
-5 = -5 + b
0 = b
y = 5/4 x + 0 or simply just y = 5/4 x.
