Log base 2 (1/4) ...?

liubo4ka [24]

Log ( base 2 ) ( 1 / 4 ) =
= log ( base 2 ) ( 2 ^(-2 ) ) =
= - 2 log ( base 2 ) 2 = ( because : log x^n = n log x )
= ( - 2 ) * 1 = ( because: log (base x) x = 1 )
= - 2

Y+3=4 WHAT DOES Y EQUEL?

DedPeter [7]

Answer: y=1

Step-by-step explanation:

First we need to get y alone.

y+3 = 4

We must subtract 3 on both sides (this will cancel out the +3 on the y side).

y=1

If you had y-3=4 then you would have to add 3 on both sides to cancel out the -3 on the y side.

If it is division you multiply and vise versa. Just do the opposite to everything on the y side to give y alone and figure out what y is equal to!

:) Best of luck!

A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rat

oksano4ka [1.4K]

Answer-

The insect population at the end of week 11 is 1730.

Solution-

A population of insects grows exponentially.

The general form of exponential function is,

$y=ab^x$

Where,

a, b are constants.

Putting the data given in the table, in the the equation in order to get the values of a, b

At (0, 20)

$\Rightarrow 20=ab^0$

$\Rightarrow a\cdot (1)=20$

$\Rightarrow a=20$

Now the exponential function becomes,

$y=20b^x$

At (1, 30)

$\Rightarrow 30=20b^1$

$\Rightarrow 20b=30$

$\Rightarrow b=\dfrac{30}{20}$

$\Rightarrow b=\dfrac{3}{2}$

Now the equation becomes,

$y=20(\frac{3}{2})^x$

For calculating the number of insects at the end of the 11th week, putting x=11, so

$y=20(\frac{3}{2})^{11}$

$=1729.95 \approx 1730$
