Answer:
4.96 years
Step-by-step explanation:
use the rule of 72
Y = 72 / r and r = 72 / Y
y= years
r= rate
Answer:
Step-by-step explanation:
<u>Use two points on the graph to get an equation:</u>
<u>The slope</u>: m = (60 - 8)/6 = 8.667
<u>The y- intercept</u> is 8
<u>The equation of the line of best fit:</u>
Parallel lines have the same slope, so if you need a line parallel to this one, it'll share a slope of (7/4). for future reference, perpendicular lines have opposite reciprocal slopes. you change the sign, then flip the fraction. -2 would become 1/2; as slopes, these would be perpendicular lines.
Answer:
the answer is option B
Step-by-step explanation:
To find dy/dx the equation here is
first multipled by derivative of second + second multipled by derivative of first
y = x*sinx
dy/dx = x * derivative of sinx + sinx * derivative of x
derivative of x with respect to x is 1
derivative of sinx with respect to x is cosx
therefore
dy/dx = x * cosx + sinx * 1
= x * cosx + sinx
