Jordan enters 3.4 x6.8 into his calculator. He writes the digits 2312 from the display and forgets the decimal point. Where shou

vivado [14]

Answer:

23.12

Step-by-step explanation:

Jordan has entered 3.4 x 6.8 on his calculator.

3.4 x 6.8 = (34/10) x (68/10) = (34 x 68) / (100) = 23.12

Or an easier way would be, observing the two numbers.

In 3.4 , there is one digit after decimal point.

In 6.8 there is one digit after decimal point.

So in their product there should be two digits after the decimal point.

So the answer is <em>23.12</em>

(4/3)^1-x = e^x (solve exponential equation)

Alex777 [14]

we are given

$(\frac{4}{3} )^{1-x}=e^x$

Since, we have to solve for x

so, firstly we will isolate x on any one side

we can take ln on both sides

$ln((\frac{4}{3} )^{1-x})=ln(e^x)$

now, we can simplify it

$(4-x)ln((\frac{4}{3} )=x$

now, we can move all x terms altogether

$4*ln(\frac{4}{3})-xln(\frac{4}{3})=x$

$xln(\frac{4}{3})+x=4*ln(\frac{4}{3})$

$x(ln(\frac{4}{3})+1)=4ln(\frac{4}{3})$

so, we get

$x=\frac{4ln(\frac{4}{3})}{(ln(\frac{4}{3})+1)}$ ...........Answer

What is the value of the expression below when

DiKsa [7]

Answer:

The value of the expression is 36.

Step-by-step explanation:

If substitute the x (in 4x) with 4, and y (in 10y) with 2, we get:

4(4) + 10(2)
16 + 20
= 36

Hope this helps!!
