Are these converses true? The answer is yes. Each of these converses can be a way to show that a quadrilateral is a parallelogram. However, the Consecutive Angles Converse can be a bit tricky, considering you would have to show that each angle is supplementary to its neighbor

(∠A

and

∠B, ∠B

and

∠C, ∠C

and

∠D

, and

∠A

and

∠D)

. We will not use this converse.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The  value is  v(3) =  29.4 \  m/s

Step-by-step explanation:

From the question we are told that

    s(t) =  -4.9t^2 + 500

And  

    \lim_{t \to a}  \frac{s(a) - s(t)}{a-t}

Generally s(t) at t = a is mathematically evaluated as

      s(a) =  -4.9a^2+ 500

So

    s(a) - s(t) =  -4.9a^2 + 500 - ( -4.9t^2+500)

     s(a) - s(t) =  -4.9a^2 + 500 +4.9t^2-500)

      s(a) - s(t) = 4.9(t^2 - a^2)

Thus the velocity is represented as

     v(t) =\lim_{t \to a}  \frac{s(a) - s(t)}{a-t} \equiv \lim_{t \to a} \frac{4.9(t^2 -  a^2 )}{ a-t}

=>     v(t) = \lim_{t \to a}  - 4.9(a + t )

=>      v(t) = -4.9 (a + a )

=>      v(t) = -9.8a

Now at  t =  3

=>  v(3) = -9.8 (3)

=>   v(3) =  29.4 \  m/s

Given two functions f(x)=2x+1 and g(x)=−13x−3 , what is the function rule for (f+g)(x)
raketka [301]

Answer:

- 11x - 2

Step-by-step explanation:

note that (f + g)(x) = f(x) + g(x)

f(x) + g(x)

= 2x + 1 - 13x - 3 ← collect like terms

= - 11x - 2
