Answer:

Step-by-step explanation:

B = 180 - 50 - 35 = 115 degrees

By the law of sines,

$c=\frac{13\sin 35^{\circ}}{\sin 115^{\crc}}$

And $a=\frac{13\sin 50^{\circ}}{\sin 115^{\circ}}$

5^(2x-1)+5^(x+1)=250 how do you solve? thank you

zepelin [54]

Answer:

x = 2

Step-by-step explanation:

Exponential Equations

Solve:

$5^{2x-1}+5^{x+1}=250$

Separate each exponential:

$5^{2x}5^{-1}+5^{x}5^{1}=250$

Operating:

$\displaystyle \frac{5^{2x}}{5}+5^{x}5=250$

Multiplying by 5:

$5^{2x}+25\cdot5^x=1250$

Rearranging:

$5^{2x}+25\cdot5^x-1250=0$

Recall that:

$5^{2x}=(5^{x})^2$

$(5^{x})^2+25\cdot5^x-1250=0$

Calling

$y=5^{x}:$

$y^2+25y-1250=0$

Factoring:

$(y-25)(y+50)=0$

There are two possible solutions:

y=25

y=-50

Since

$y=5^{x}$

y cannot be negative, thus:

$5^{x}=25=5^2$

The solution is:

x = 2

Is the value of the 1 in 1,440,000 10 times as great as the value of the 4 in the hundred thousands place ? Explain

Burka [1]

I do not think so, because it has to be the same number.
Ex: 5,539 - in this the 5 in the thousands place is greater than the 5 in the hundreds place
