H=vt+1/2gt^2 solving for G <br>GIVING BRAINLISEST
ololo11 [35]

Answer:

g=\frac{2h}{t^2}-\frac{2v}{t}

Step-by-step explanation:

So we have the equation:

h=vt+\frac{1}{2}gt^2

And we want to solve for g.

First, isolate g. To do so, subtract vt from both sides:

h-vt=\frac{1}{2}gt^2

Multiply both sides by 2:

2h-2vt=gt^2

Now, divide both sides by t^2:

g=\frac{2h-2vt}{t^2}

Expand:

g=\frac{2h}{t^2}-\frac{2vt}{t^2}

Simplify the second term:

g=\frac{2h}{t^2}-\frac{2v}{t}

And we're done!

Find two positive real numbers whose product is a maximum. the sum is 80
Eduardwww [97]
Let's say the numbers are "a" and "b"

thus \bf y=ab\qquad &#10;\begin{cases}&#10;a+b=80\\&#10;b=80-a&#10;\end{cases}\implies y=a(80-a)\implies y=80a-a^2\\\\&#10;-----------------------------\\\\&#10;\cfrac{dy}{da}=80-2a

set the derivative to 0, and check the critical points, there's only one anyway

and do a first-derivative test, to see if it's a maximum

2x^3-3x^2+kx-1 is divided (x-1),the remainder is 2 find k
Debora [2.8K]

Answer:

k = 4

Step-by-step explanation:

if f(x) is divided by (x - h) then f(h) is the remainder

f(x) = 2x³ - 3x² + kx - 1

divided by (x - 1) , so h = 1 , then

2(1)³ - 3(1)² + k(1) - 1 = 2

2 - 3 + k - 1 = 2

- 2 + k = 2 ( add 2 to both sides )

k = 4
