Answer:
y=25x+7
Step-by-step explanation:
The equation will be in the form of y=mx+c where m is gradient/slope and c is constant,
normally referred as y intercept.
Slope is given by dividing change in y by change in x
Slope=(57-32)/(2-1)=25
Therefore slope is 25
For the first term
32=25(1)+c
C=32-25=7
Therefore, the general equation will be y=25x+7
That would be
12,000(1.05)^2 = 13,230
<em><u>(0.2)x = 2.</u></em>
<em><u>Taking log on both sides</u></em>
<em><u>log (0.2)x = log 2.</u></em>
<em><u>x</u></em><em><u> </u></em><em><u>log (0.2) = 0.3010, [since log 2 = 0.3010].</u></em>
<em><u>x</u></em><em><u> </u></em><em><u>log (2/10) = 0.3010.</u></em>
<em><u>x</u></em><em><u> </u></em><em><u>[log 2 - log 10] = 0.3010.</u></em>
<em><u>x</u></em><em><u> </u></em><em><u>[log 2 - 1] = 0.3010,[since log 10=1].</u></em>
<em><u>x[-0.699] = 0.3010.</u></em>
<em><u>x</u></em><em><u>=</u></em><em><u> </u></em><em><u>0.3010/-0.699.</u></em>
<em><u>x</u></em><em><u>=</u></em><em><u> </u></em><em><u>= -0.4306….</u></em>
<em><u>x</u></em><em><u>=</u></em><em><u> </u></em><em><u>= -0.4</u></em><em><u>.</u></em>
