we know that

The multiplicative rate of change of the exponential function between two points is equal to

$[f(b) / f(a) ] / (b-a)$

Let

$A(1,6)\\B(2,4)$

we have that

$f(a)=6\\f(b)=4\\a=1\\b=2$

substitute in the formula

$[4 / 6 ] / (2-1)=4/6=2/3$

Let

$A(3,8/3)\\B(4,16/9)$

we have that

$f(a)=8/3\\f(b)=16/9\\a=3\\b=4$

substitute in the formula

$[(16/9) / (8/3) ] / (4-3)=48/72=2/3$

therefore

<u>the answer is the option</u>

Find a right triangle that has legs with your irrational Lengths and a hypotenuse with a rational Length

cluponka [151]

gg easy

the legs of a triangle are related as $a^2+b^2=c^2$ wehre a, b, and c are the legs and the hypotonuse of a triangle respectively

let's find some stuff

one easy way is to find a rational value for c find values of a and b

lets pick c=5

$a^2+b^2=5^2$

$a^2+b^2=25$

now split up 25 into 2 things that don't have rational square roots

if we say $a^2=19$ and $b^2=6$ then we get

$a=\sqrt{19}$ and $b=\sqrt{6}$ (which are both irrational)

Round 1627187 to the nearest ten?

Eduardwww [97]

Answer:

1627190

Step-by-step explanation:

(see attached for reference)

Given the number 1627187, we can see that the number in the tens place is the number 8.

How we round this depends on the number immediately to the right of this number. (i.e the digit in the ones place)

Case 1: If the digit in the ones place is less less than 5, then the number in the tens place remains the same and replace all the digits to its right with zeros

Case 2: If the digit in the ones places is 5 or greater, then we increase the digit in the tens place and replace all the digits to its right with zeros.

In our case, the digit in the ones places is 7, this greater than 5, hence according to Case 2 above, we increase the digit in the tens place by one (from 8 to 9) and replace all the digits to its right by zeros giving us:

1627190
