Answer:
first you must know how many 3/4 do you have
because of scale
and after that multiply to 5 to get actual length
We can first factor all the terms by 2:
<span>6x^2 - 10x - 4=2(3x^2-5x-2)
</span>
Then we solve 3x^2-5x-2=0.
Discriminant : 25+4*3*2=49=7^2 hence the roots are (5-7)/6 and (5+7)/6 which are -1/3 and 2
Hence 3x^2-5x-2=(x-2)(3x+1)
Thus 6x^2-10x-4=2(x-2)(3x+1)
Answer:
y = 400(1.01)^t
Step-by-step explanation:
Firstly find the rate
(Take any balance for two years, e. g 400 and 404,412.12 and 416.24,etc to get simple interest)
408.04-404= 4.04
I=(P*R*T)/100
From which R=(100*I)/PT
R= 100*4.04/404*1
R=1%
Using compound interest formula
A =P(1+r/100)^n
where n is time
substituting each value
y = 400(1+1/100)^t
y= 400(1.01)^t
