Si las propociciones p , q y r son verdaderas , falsa y verdadera , respectivamente determinar el valor de verdad de las siguientes proposiciones I.- ( pVq)^r II.- ⁓(p^r)Vq III⁓(pV⁓q)^r rapido pls , es para una practica ✋

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

you would need to also lose 1 point for each of the other outcomes for it to be fair.

step-by-step explanation:

hello umm i don't understand your question can you explain it more pls

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
