Answer:

± 1/4 sqrt((400-y))  =t

Step-by-step explanation:

Y=-16t^2 + 400

Subtract 400 from each side

y - 400 = -16t^2 +400-400

y-400 = -16t^2

Divide by -16t^2

(y-400)/-16 = t^2

(400-y)/16 = t^2

Take the square root of each side

±sqrt((400-y)/16) =sqrt(t^2)

±sqrt((400-y)) / sqrt(16) =t

± 1/4 sqrt((400-y))  =t

emmainna [20.7K]

Answer:

A=150.72 m^2

Step-by-step explanation:

Using the formula for the surface area of a cylinder

A=2\pi rh+2\pi r^2

As we know that r=3, h=5, and \pi =3.14 we can substitute in these values into the equation and then solve it

A=2(3.14)(3)(5)+2(3.14)(3)^2\\\\A=94.20+56.52\\\\A=150.72

Brrunno [24]

Answer:

a) what is the probability that Neither will of these products launch ?

= 0.30

b) At least one product will be launched ?

= 0.70

Step-by-step explanation:

From the above question, we have the following information:

P(A) = 0.45

P(B) = 0.60

P(A ∩ B) = P(A and B) launching = 0.35

Step 1

We find the Probability that A or B will launch

P (A ∪ B) = P(A) + P(B) - P(A ∩ B)

= 0.60 + 0.45 - 0.35

= 1.05 - 0.35

= 0.70

a) what is the probability that Neither will of these products launch ?

1 - Probability ( A or B will launch)

= 1 - 0.70

= 0.30

b)At least one product will be launched?

This is equivalent to the probability that A or B will be launched

P (A ∪ B) = P(A) + P(B) - P(A ∩ B)

= 0.60 + 0.45 - 0.35

= 1.05 - 0.35

= 0.70
