The answer to this question would be: 17 years
The <span>interest rate is 3.8% compounded twice a year. The function of the saving account amount would be:
f(x)= </span><span>4,790.23* (1+ 0.038/2)^2x
</span>f(x)= 4,790.23* (1.019)^2x
Then for f(x)= 9,000 the x value would be:
9,000= 4,790.23* (1.019)^2x
9,000/4,790.23= (1.019)^2x
1.8788= (1.019)^2x
<span>2x=34
</span>x=17
Answer:
C 84.2-79.2/SQRoot(10.2^2/50 + of of 6.8^2/30)
Step-by-step explanation:
Step-by-step explanation:
A straight line graph is of the form:
y = mx+b
So we get our equation in this form:
9=2x+3y
or, 9-2x=3y
or, -2x+9 = 3y
or, y= (-2x+9)/3
or, y = -2/3x + 3
So,
Slope(m)=−2/3
y-intercept (b) = 3
Therefore, slope(m) is -2/3x and y-intercept(b) is 3.
It would take Stan 30 minutes and Hilda 15 minutes
