Answer:
Step-by-step explanation:
Let's find the answer by using the arc length formula which is:
First, let's find dy/dx which is:
y=4x-5
y'=4*(1)-0
y'=4, now let's use the formula:
Now, using the distance formula we have:
So we have two points (-1, -9) and (3, 7) so:
Notice both equations gave the same length .
$1,954
Picture 1 x = 43°
Picture 1 - When a triangle is formed inside a semicircle, two lines from either side of the diameter meet at a point on the circumference at a right angle.
180 - 47-90= 43° = x
$89.1
13.5 % of $660
= 13.5/ 100 × 660
= 0.135 × 660
= 89.1
hence, $ 89.1
the interest is 195dollars
