I not sure what the question is here. Is 67,000 closer to what? If you are rounding then it would be closer to 70,000

67,000 is closer to 70,000 because when you were rounding numbers it is the rule that five or more goes up and lower than five so like four goes down

Y =square root 1-x/1+x find it's derivative

tiny-mole [99]

Answer:

The first derivative of $y = \sqrt{\frac{1-x}{1+x} }$ is $y' = -\frac{1}{(1-x)\cdot (1+x)^{3/2}}$ .

Step-by-step explanation:

Let $y = \sqrt{\frac{1-x}{1+x} }$ . we can determine its first derivative by Rule for the Square Root Function, Rule for Power Function, Rule of Chain and Rule for the Addition of Functions, Rule for the Subtraction of Functions, Rule for the Division of Functions:

$y' = \frac{1}{2\cdot \sqrt{\frac{1-x}{1+x} }}\cdot \frac{(-1)\cdot (1+x)-(1)\cdot (1-x)}{(1+x)^{2}}$

$y' = \frac{1}{2}\cdot \sqrt{\frac{1+x}{1-x} }\cdot \left[\frac{-1-x-1+x}{(1+x)^{2}} \right]$

$y' = \frac{1}{2}\cdot \sqrt{\frac{1+x}{1-x} } \cdot \left[-\frac{2}{(1+x)^{2}} \right]$

$y' = -\frac{1}{(1-x)\cdot (1+x)^{3/2}}$

The first derivative of $y = \sqrt{\frac{1-x}{1+x} }$ is $y' = -\frac{1}{(1-x)\cdot (1+x)^{3/2}}$ .

Given: AD = BC and AD || BC

o-na [289]

Answer:

See below

Step-by-step explanation:

Proof:

Statements | Reasons

AD ≅ BC | Given

AD ║ BC | Given

AC ≅ AC | Reflexive Property

∠DAC ≅ ∠ACB | If 2 || lines are cut by a trans., the | alternate interior ∠s are congruent.

ΔADC ≅ ΔBCA | S.A.S Postulate

BA ≅ DC | Corresponding sides of congruent Δs

So, quad. ABCD is a ║gm | If a quad. has its opposite sides

| congruent, the quad. is a parallelogram.

7. What is the next fraction in each of the following patterns?

serious [3.7K]

Answer:

36/40, 47/101, 192

Step-by-step explanation:

(a)The numerator (top number of the fraction) is adding up by odd numbers in order.

From 1/40 to 4/40 you add 3, from 4/40 to 9/40 you add 5, from 9/40 to 16/40 you add 7, and from 16/40 to 25/40 you add 9.

The next number to add would logically be 11. So from 25/40 you would go to 36/40.

36/40 is your next fraction.

(b)

3+4=7,4+7=11,7+11=18,11+18=29,18+29=47
