If you launch the cannonball from the ground instead (hi=0), what does that change in the original equation?
ikadub [295]

Answer:

  the value of hi changes from 58 to 0:

  h(t) = -4.9t^2 +19.8t

Step-by-step explanation:

If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.

  h(t)=-4.9t^2+19.8t+0\\\\\boxed{h(t)=-4.9t^2+19.8t}

Vector v is plotted below. What is the length of the x-component of v?
Rzqust [24]
Answer:

C. 1

Step-by-step explanation:

We can see that each box in the grid is one unit.

We count one box to the right on the horizontal axis and 4 boxes down on the vertical axes to obtain the components of vector v.

See graph in attachment.

Therefore the components of vector v is

\binom{1}{-4}.

The length of the x component is 1 unit

Hence the correct answer is C.

Solve for c<br><br><br> R=5(c/a-0.3)
aalyn [17]

we have

R=5(c/a-0.3)

Solve for c--------> that means that clear variable c

so

Divide by 5 both sides

R/5=(c/a-0.3)

Adds 0.3 both sides

(R/5)+0.3=(c/a)

Multiply by a both sides

a[(R/5)+0.3]=c

so

c=a[(R/5)+0.3]

therefore

<u>the answer is</u>

c=a[(R/5)+0.3]

#6) BRAINLIEST + 10 + POINTS! :D
kumpel [21]

Answer:

B

Step-by-step explanation:

Notice that if we divide our given equation (2x - 4 = 6) by 2 from both sides, we get:

(2/2)x - (4/2) = (6/2)

x - 2 = 3

Now, notice what happens if we multiply this by -3:

-3 * (x - 2) = 3 * (-3)

-3 * x + (-3) * (-2) = -9

-3x + 6 = -9

This matches B.

Hope this helps!

What is the domain and the range of these functions?? quick please!!!!!!!!!!
Sever21 [200]
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. A rational function is a function of the form f(x)=p(x)q(x) , where p(x) and q(x) are polynomials and q(x)≠0 .
