Answer:

3.75 seconds

Step-by-step explanation:

<u>Given:</u>

h(t)=-16t^2+Vt+h

h=2

V=180

<u>Plug in given info into formula:</u>

h(t)=-16t^2+120t+2

<u>Find the x-coordinate of the vertex:</u>

<u />t=-\frac{b}{2a}<u />

t=-\frac{120}{2(-16)}

t=-\frac{120}{-32}

t=\frac{15}{4}

t=3.75

Would this be correct even though I didn’t use the chain rule to solve?
Semenov [28]

Answer:

Dy/Dx=1/√ (2x+3)

Yeah it's correct

Step-by-step explanation:

Applying differential by chain differentiation method.

The differential of y = √(2x+3) with respect to x

y = √(2x+3)

Let y = √u

Y = u^½

U = 2x +3

The formula for chain differentiation is

Dy/Dx = Dy/Du *Du/Dx

So

Dy/Dx = Dy/Du *Du/Dx

Dy/Du= 1/2u^-½

Du/Dx = 2

Dy/Dx =( 1/2u^-½)2

Dy/Dx= u^-½

Dy/Dx=1/√ u

But u = 2x+3

Dy/Dx=1/√ (2x+3)

Starting with the graph of f(x) = 5^{x}, write the equation of the graph that results from (a) shifting f(x) 1 units downward. y
aev [14]
1 down, means minus 1 from whole equation
moving 1 to left means add 1 to every x
reflecting across x axis means multiply every x by -1

a. y=5^x+1
b. y=5^{x+1}
c. y=5^{-x}
