The slope of the tangent at a given point can be found by differentiating the given equation and substituting the value of x at the point as such:
y = 9 - x²
dy/dx = -2x; x = 1
dy/dx = -2
For a line with the slope of -2 and passing through point (1 , 12)
y -12 = -2(x - 1)
The shape shown is a cone and the cones perpendicular cross section is a triangle.
If you need the parallel cross section then it will be a circle.
The answer is A.
Hope this helps :)
Answer:
y=18.2
Step-by-step explanation:
-3x+5y=22
-3(37-14)+5y=22
-69+5y=22
5y=91
y=18.2
check:
-3(37-14)+5(18.2)=22
-69+91=22
22=22

Answer:
If the interest is yearly $2702.87 will be owed
Step-by-step explanation:
first you would need to find out how much 11.3% of $1205 is which is $136.17. And since the interest is yearly you would multiply the $136.17 by the 11 years which would be $1497.87. Then you would add the amount that they borrowed to the interest that they would owe after 11 years which would be $1497.87 + $1205 = $2702.87. So after 11 years the total amount that must be repaid is $2702.87
