Answer:
-16t²+17t+7=11
==>16t²-17t+4=0
Δ=17²-4*4*16=33
==>t= (17-√33)/32=0.351732... (s)≈0.35 (s)
or t=(17+√33)/32=0.710767 (s)≈0.71 (s)

Step-by-step explanation:
Consider the expression
First, use the commutative property over addition:
Then, use the associative property over addition:
Now, it is easy to add 5 and 65:

Answer:
Radio es 8.799974535 cm
Diametro es 17.59994907 cm
Explicación paso a paso:
Como tienes la medida en cm, me indica que es el perimetro del circulo
C=πd
55.292=3.1416 d
\frac{55.292}{3.1416} =d
3.1416
55.292
=d
17.59994907=d
Para sacar radio hay que dividir entre 2
r=8.799974535
The answer is 2/10 simplified to 1/5
49/2= 24.5
Z=24.5
Since you need to get rid of the 2 just divide 49 by 2 and that's what Z equals
