Well, the answer would be square root of 3 over 2 because of the unit circle. So, the answer choice should be which ever one involved square root 3 over 2
The speed of the plane will be equal to 240 Mph.
<h3>What is speed?</h3>
Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
Given that:-
- Mattie Evans drove 350 miles in the same amount of time that it took a turbo propeller plane to travel 1200 miles.
- The speed of the plane was 170 mph faster than the speed of the car.
The speed of the plane will be calculated as:-
Let the speed of the car will be x mph so the speed of the plane will be
(x + 170)
Now time for the plane:-
Tp = Dp / Sp
Tp = 1200 / (x+170)
Now time for the car:-
Tc = Dc / Sc
Tc = 350 / x
It is given that time taken by both the plane and the car are equal:-
Tp = Tc
1200 / x+170 = 350 / x
1200x = 350x + 59500
850x = 59500
x = 59500 / 850
x = 70mph
The speed of the plane will be calculated By:-
Sp = x + 170 = 70 + 170 = 240 Mph
Therefore the speed of the plane will be equal to 240 Mph.

Answer:
Step-by-step explanation:
a) f(x) = x² y f(x) = (x+1)²-4 tienen la misma forma y orientación.
b) f(x) = x² se encuentra debajo y a la izquierda de f(x) = (x+1)²-4.
c) En la función f(x) = (x + 1)²-4 el vértice tiene un desplazamiento horizontal, 1 unidad hacia la izquierda.
d) el vértice de la función f(x) = (x + 1)²-4 está desplazado verticalmente, 4 unidades hacia abajo.
20.25 because 1 mile takes 0.75 minutes
So break it down to decimals, if we know that 1/4 is 0.25 then we can work off of the left numberstart at the lowest possible, 1/51/5=0.2in this case 1/4 is larger than 1/5 so we go 2/5>1/42/5=0.4 which is larger than 0.25So 2 would be the lowest whole number to complete the comparison
2/5>1/4
