A formula is expressed as D= a(2+kt). Express k in terms of D,a, and t.
Yuri [45]
This is just rearranging terms, it gets kind of ugly though. Start by dividing both sides by a to get D/a=2+kt, next move the 2 over to the left to get (D/a)-2=kt, finally divide the whole expression by t to get ((D/a)-2)/t=k

4x2 + y2 = 36<br> Obtener dominio
Veronika [31]

<em>Answer:</em>

<em>[-3,3]</em>

<em>Step-by-step explanation:</em>

<em>Write the problem as a mathematical expression.</em>

<em>4x^2+y^2=36</em>

<em>Subtract 4x^2 from both sides of the equation.</em>

<em>y^2=36-4x^2</em>

<em>Take the square root of both sides of the equation to eliminate the exponent on the left side.</em>

<em>y= + and - </em>\sqrt{36-4x^2}<em />

<em>The complete solution is the result of both the positive and negative portions of the solution.</em>

<em>y= </em>2\sqrt{(3+x)(3-x)<em />

<em />y= -2\sqrt{(3+x)(3-x)}<em />

<em>Set the radicand in </em>\sqrt{(3+x)(3-x)} \geq 0<em> greater than or equal to 0 to find where the expression is defined.</em>

<em />(3+x)(3-x)\geq 0<em />

<em>So your answer would be [-3,3]</em>

Using distributive property what is the value of the expression for 2(-5 + 3)
Vladimir [108]

Answer:

-4

Step-by-step explanation:

According to the rules of the distributive property, you have to multiply the term outside of the parentheses with the terms inside the parentheses first.

1. 2(-5)=-10    

2. 2(3)=6

The terms that we have are now -10 and 6. Add them together to get the final answer.

-10+6=-4

A set of numbers was created using a rule that states, "Start with 2, multiply by 3." Write the numbers included
WITCHER [35]
2, 6, 18, 54, 162, 486...

Start with the number 2.
2*3=6 \\ 6*3=18 \\ 18*3=54 \\ 54*3=162 \\ 162*3=486
And continue with that pattern from there.

Can anyone help me with the answer to this please?
stiks02 [169]

Answer:

Step-by-step explanation:

To find the inverse function switch variables out and solve for y

If

y=(x+3)/x swap variables to get

(y+3)/y=x then solve for y

y+3=yx

y-yx+3=0

y-yx=-3

y(1-x)=-3

y=-3/(1-x)

y=3/(x-1)
